8 Revolutionary Real-World Blockchain Use Cases

The origin of Blockchain can be traced back to the 90’s, ancient for the world of IT, but the technology only recently gained traction due to the success of Bitcoin. However, a few unique advantages of blockchain make it perfectly suitable for use outside of the crypto- world. In this article, DSR answers the questions: Why is blockchain is so popular nowadays? Which industries are already being impacted by blockchain? Where are we headed with blockchain in the future?

Blockchain’s unique advantages have allowed it to step into industries and areas of life such as banking, supply chain management, refugee registration, digital identity and citizenship, healthcare, land and (intellectual) property registration, and even video games. The technology is security, private, and transparency oriented.

The following are the key benefits of blockchain that make it a unique, emerging technology:
Distributed. The blockchain is a P2P network with equal nodes.
Decentralization. The technology doesn’t rely on any central point of control. Therefore, a blockchain system is reliable, verifiable, and secure from third party tampering.
Consensual. Consensus protocols create agreement between nodes, generating irrefutable and verifiable receipts
Immutability. Information stored on the blockchain is immune to most manipulation and fraud. Guaranteed by hash anchoring and Merkle trees, the blockchain provides a verifiable history of all transactions.

The explosion of blockchain-based cryptocurrencies made the technology more mature and robust. Many of its initial drawbacks were eliminated: consensus protocols have become much more effective, performance is improved (as a pioneer, Bitcoin’s blockchain processes just 4.6 transactions per second, versus Visa’s 1,700 transactions per second), and vulnerabilities to the new types of attacks were identified and fixed.

These key, proven advantages makes blockchain a must for various real-world applications where security, transparency, and fraud protection are paramount.

Smart contracts

If we take a look at any information system, we can identify two main components: data or the information itself, and the way it is managed. In the case of cryptocurrency, the data is the amount of currency on a user’s account, and smart contracts are the way we manage and verify that data. Basic smart contracts (SC) can be found in Bitcoin, where a stack-oriented programming language is used. The concept of smart contracts was initially introduced in 1994 by Nick Szabo, a famous cryptographer, legal scholar, and computer scientist. Szabo’s revolutionary idea finally came to life with the appearance of blockchain.

Smart contracts allow for the creation of various data storage and processing systems based on the decentralized blockchain. All of the operations performed on data are defined by mathematical rules.

Key advantages of blockchain-based smart contracts:
• No server failures, intrinsic to the system’s decentralized nature.
• No censorship or threats of data manipulation/stealing.

With the help of SCs on the blockchain, we can create reliable and secured registers for everything; from the storage of intellectual property, to CryptoKitties (virtual, Etherium-based pets).

Digital identity

Identity management and security are a couple of the massive, crucial issues facing the web today. The global identity and access management market is going to reach a whopping $14.82 billion by 2021 according to KBV Research. Despite massive investment, traditional systems are still suffering from all sorts of vulnerabilities.

Blockchain holds the answer. Blockchain’s properties make it the backbone of Self-Sovereign Identity (SSI) a secure, reliable system of digital identity management. SSI data cannot be forged by design, and its’ level of security exceeds any conventional identification system.

Below we’ll show some impressive examples of blockchain use in digital identity management systems as well as in the supply chain, healthcare, automotive, banking, property registration, and even state election industries.

8 Revolutionary Blockchain Use Cases

Hyperledger Indy

Hyperledger Indy is an open-source project and one of several, well-established distributed ledgers built exclusively for decentralized identity. It features some evident advantages such as robust interoperability, zero-knowledge proof security, and anonymous credentials support.

The following are potential use cases for Hyperledger Indy:
• Digitization and verification of documents such as driver’s licenses and passports
• Secure, password-less authentication (SPA). On-site authorization with biometric data (like fingerprint scan) via user’s mobile device
• Membership management
• Sophisticated spam filters
• Age or basic credential verification (for online purchasing access, etc.)
• Secure and intuitive document and digital file exchange (purchase orders, invoices, design schemes, etc.)
• Employment verification
• Supply-chain inventory tracking and provenance
• Trusted peer-to-peer communication

Hyperledger Indy provides libraries, necessary components, SDKs, and detailed documentation. The platform can be used to build secure systems based on SSI.

You can learn more information about Hyperledger Indy on the official website or in person by visiting nearest community event or meeting, such as the Hyperledger Bootcamp Moscow which DSR attended in October.

MyClinic, Medicalchain

Medicalchain uses blockchain to create secured, electronic clinical records, monitor patients’ treatments, and share lab tests and other relevant diagnostic data between countries with different legal systems.

This is a great example of securing sensitive information and ensuring interoperability in healthcare systems which differ significantly not only from one another, but also from conventional data storage systems.

Renault

This blockchain-based system was created in collaboration with Microsoft (Azure Blockchain) and Viseo. The Renault system is used to identify a car, track any road traffic accidents related to it, build original spare parts catalogues to fight counterfeit products, and track car maintenance and insurance history.

Barclays

With the help of the startup Wave, Barclays has created a Letter of Credit system based on blockchain. Barclays claims this is a faster, more secured, and easy-to-use way of executing global trade transactions. Trade documentation is handled on the Wave platform and funds sent via Swift.

The bank claims that this is first-ever case of a live trade transaction using blockchain technology.
Barclays is hoping to get other banks on board with supporting the Wave platform in order to improve trade documentation management.

The new blockchain-based system helps to speed up trade transactions, reduce cost for companies around the world, optimize internal processes for banks, and eliminate the risk of documentary fraud.

Cambridge blockchain, CULedger, Masterchain

The emergence of “know your customer” blockchain use cases is going to be a huge disruption in the financial world. Blockchain is being used to make it fast and easy to identify and verify customers.

CULedger, for instance, is a global, distributed ledger with based on self-sovereign, digital-identity, built to reduce cybersecurity and fraud risks, improve the member experience, and reduce costs. The initiative works via a consortium made up of credit unions and trusted industry investors.

In Russia, Masterchain is being utilized by some of the countries biggest banks. Masterchain is a blockchain-based “know your customer” project to establish a secure and fast way to identify clients and access their financial history, without disclosing any personal or sensitive information unless the customer gives their informed consent.

Banks and large corporations are actively seeking ways to use blockchain in their operational activities and they are working together to explore blockchain technology and its applications. One such example is Consortium R3, with more than 300 participants across a variety of industries.

TradeLens

TradeLens is a blockchain platform built by IBM and Maersk which ships freights all over the world. It is used to manage sophisticated supply chains and involves smart contracts. This system is already being deployed around the world.

The supply chain system involves regulatory authorities, international ports, shipping hubs, etc. Sensors installed on ships, trucks, and shipping hubs are used to track freights in real-time with the help of an IoT system view and other relevant data, including shipping container weights and temperatures inside.

The TradeLens blockchain platform and smart contracts are used to establish the fast and secure sharing of shipping data from a single source with different supply chain participants like a cargo receiver, customs controller, delivery company, freight terminal, and other involved parties.

Follow My Vote

This online voting solution utilizes blockchain to ensure transparency and battle fraudulent activities in the voting system. Follow my vote provides the ability to prove the accuracy of election results by mathematical methods. It uses a blind signature approach to eliminate the need for procedural security in traditional election systems.

Blockchain technology brings a variety of advantages to the online election solution:
Security. Ballots are securely stored and cannot be altered by any party.
Privacy. Sophisticated and independently tested cryptographic algorithms ensure the privacy of voters’ data.
Voter Intent Verification. A voter can verify they casted their vote as intended.
Transparency. Any voter or party can audit each registered ballot to verify the legitimacy of results and the credibility of elections.

Georgia Land Registry

This is the first-ever nationwide land-registry system. Built in collaboration with the government of Georgia and launched in 2016, more than 1.5 million land registry entries have been made so far.

Immutable by design, blockchain technology guarantees citizens’ records are safe and cannot be forged by any party.

The Exonum platform greatly increases the speed of the registration process (less than 3 minutes) and a timestamping feature ensures independent validation of the land property title deed using cryptographic proof (hash). published on the Bitcoin Blockchain. In case of any doubt, a citizen can prove their ownership by providing the timestamp.

Key blockchain platforms
• Hyperledger (Indy, Fabric, Sawtooth, Iroha)
• R3 Corda
• Exonum
• Tendermint
• Verify

There are even more exciting and revolutionary blockchain use cases coming in the near future like access control and management solutions. Stay tuned on DSR Corporation’s blog to read more insights into cutting-edge technologies of M2M, IoT, machine learning, computer vision and other IT industries.

World Ruled by Robots?

“What’s New in the World of Artificial Intelligence?” asked me Alexa….

Some people believe that artificial intelligence does not exist, while others watch Sci-Fi movies and devise survival plans for when robots rise against us. Artificial intelligence today is weak, meaning many of the tasks and operations being performed now are limited in scope, but that is continuing to change every day. The development of AI is building at a rapid pace and is poised to change how we interact with the world around us on a daily basis.

Recently, with the help of artificial intelligence, companies are beginning to solve individual niche issues.  For example, emails and responses can be automated in the workplace, reducing the need for human attention. Self-driving cars are operating independently and more safely, reducing the number of accidents on roads. Experts have even predicted that in 10 years self-driving cars will be a normal reality in the US, along with radical organizational and cost structure changes for transportation companies like taxi and bus services.

Social networks, neural networks, and learning algorithms… Russian search engine Yandex is currently conducting closed testing of a new social network using AI and neural networks. Access is only available by invitation of someone who already exists on the network. By tapping into AI and neural networks, you are able to find completely new friends solely on the information you have provided to the system. The algorithms are configured so that you see people based along your selected features. Interestingly, the development with the use of artificial intelligence began to appear in areas such as beauty, cosmetology, and health.

Other large companies continue to use artificial intelligence to help predict events. Mobile operators can analyze the behavior of subscribers in order to offer services that will help improve the user experience, while other applications of modern development are aimed at helping users make decisions.

Google, Siri, Alexa, Cortana, Alice, how many virtual assistants can you remember?  There are many others, but these are some of the most popular we see today. Each of these assistants can allow you to do basic searches, analyze or processes information, but the fact remains that each assistant relates back to weak AI. Just think about how many times you’ve tried to talk humanly and gotten a response that didn’t quite seem to make any sense.

So why don’t we see strong artificial intelligence?  Well, why grow an artificial tree, if you can grow the present faster and cheaper?  Perhaps humanity doesn’t need strong AI just yet.

We are going to continue to dive deeper into this subject in our next issue. In the meantime, please remember that not all robots can be correlated with artificial intelligence. If you have a floor cleaning robot at home, this does not mean that it can study neural networks, collect or process your personal data.

Thoughts After CES 2019

CES 2019 at a Glance

Every year we make our way to CES (Consumer Electronics Show) in Las Vegas for the annual consumer electronics exhibition. Imagine over 4,500 vendors presenting new ideas and technological developments spread across an entire week — it really does give a whole new meaning to the city of lights. CES presents a great opportunity to meet like-minded individuals in similar fields, or different, helping catch new ideas, contacts, and ideas – it’s wonderful here.

The history of CES began over 52 years ago with organizers showing more progress each and every year. With the main theme being innovation and information technology, the width of coverage is vast:

  • Robotics,
  • Artificial Intelligence,
  • Three-dimensional Printing,
  • Design,
  • Drones,
  • Sport Technologies,
  • Smart Home,
  • Family & Lifestyle,
  • Virtual Reality (VR),
  • Games,
  • Unmanned Vehicles,
  • Music,
  • Entertainment & Content,
  • Cryptocurrency,
  • Internet of Things (IoT),
  • and Machine Intelligence.

 

All About IoT

The beginning of the year confirmed that IoT is coming to the mass market.  Focus has shifted from smartphones to other smart devices — and manufactures are taking notice.  Improved air quality sensors, door positions, windows, just to provide a few quick examples.  There are even smart window systems being developed that can inform the home when a window is opened wider than an indicated gap, for example.

Consumers can now choose between a wide variety of smart devices and systems, putting real pressure on manufactures and companies to advance smart home ecosystems. But the problem doesn’t just end there. Consumers need a way to connect many different smart devices to a single system – easy management.  This is where Zigbee and other wireless technologies flex their strength; gateways with multiantenna and customization service suggestions come to the rescue.

Hi Computer, Talk to Me

Voice automation control becomes more the norm than the rarity.  It falls into many devices and almost everyone has them now. People want to have a voice assistant in their home, in the office, and in the car, like Jarvis from Iron Man. Project recipes from the Internet to the kitchen door by voice request?  Yes, please!  Yet, even Alexa from Amazon or Google-assistant do not always suit as a compromising option.  Artificial intelligence is poised to grow wiser and communicate with people better and faster.  Companies that once winced at the idea of software in their products are now flocking to CES.  For example, Procter and Gamble – L’Oreal, are developing mirrors that can look at your face to determine if your skin needs support or treatment.  Maybe just a care cream?  Cameras take pictures of the users face and follow changes of the face in real time.  Maybe they’ll even notice skin cancer in due time.

It is interesting that companies that are seemingly far from “software” come into the sphere of technology.  These companies expand the development zone to such wide branches like automation for pets, children, sleep, and beauty.  There are even smart leashes and collars!  People even get interested in buying devices that can distribute pleasant smells throughout their homes.  And what if you could connect a device that could command three-dimensional TV? Cars? Batteries? Spotify on your steering wheel?  The ideas and possibilities are endless.

Robotics help businesses change their models.  It is especially gratifying that companies competing in the past are starting to cooperate.  To denote such activity, the new term ‘coopetition’ has appeared.  ‘Coopetition’ should bring even greater breakthroughs in overall development.  Teamwork gives rise to new achievements.  SDKs help bring the product to market.  Quick starts are real.

Meet & Talk

DSR had a lot of productive meetings with existing and prospective clients and it was the most successful CES to date. DSR was also a proud  sponsor of the Zigbee Alliance Social – an invitation only event that was a great opportunity to bring all of the members together in one location and celebrate Zigbee successes from 2018. During this event, Zigbee Alliance announced several of the new developments and expansions of the standard and also unveil the location of the next member meeting. The atmosphere for the event was very warm and inviting and perfect for conversations and celebration.

In Closing

Here are seven key CES 2019 takeaways that caught our attention:

  • IoT is finally an emerging mass market (and the data it gathers has lots of financial implications)
  • Amazon and Google are in “hand-to-hand combat” driving voice technology into the Smart Home and beyond
  • 5G, NB-IOT and Cat-M1 are expanding battery-powered WAN connectivity in amazing ways
  • Drones—from airborne to underwater to John Deere—are becoming platforms
  • Robotics are creating business change
  • Artificial Intelligence is getting smarter
  • “Coopetition” is happening in lots of places

IoT is moving capabilities out of smart phones and into different smart things. People want their homes, cars and offices to have a voice like Jarvis (see the Ironman movie franchise). And not everyone wants Amazon Alexa or Google Assistant as the go-between. Battery-powered WAN connectivity in a variety of speeds is making the cloud easier by “losing the gateway.” Drones and robotics platforms are giving new capabilities to businesses and consumers. Artificial Intelligence (“AI”) is changing the way products and services interact with humans. And if Apple and Samsung are teaming up, is it time to evaluate how “coopetition” might help your 2019 business goals?

Why Scala Is an Awesome Programming Language

No one will argue that IT is one of the fastest developing areas of engineering. New tools, approaches and ideas complete or even supersede the existing ones. One of the quickest growing technology stacks is the Scala language stack.  In this blog we explore what makes this language awesome.

Language Design

Scala was designed to help write thread safe and laconic code. It overcomes some JVM limitations and provides features that could not be achieved in Java. Scala has a clean, expressive, and extensible syntax with lots of built-in shorthands for most common cases.

Since less code needs to be written to accomplish the same task, the programmer can now focus on the problem’s solution instead of spending the time for boilerplate code. It is especially nice if you pay your programmers for SLOC. Furthermore, Scala reduces the number of places mistakes can be made and hence improves implementation quality.

Here is a short list of Scala language and compiler features:

  • Type inference – in most cases compiler can automatically detect types of values:

val i = 1 // Int

val s = “Hello, world!” // String

  •  Named and default function arguments:

class Point(x: Int = 0, y: Int = 0)

new Point(y = 1) // Point(0, 1)

  •  Tail recursion optimization – recursive function self-calls transforms to loops – no more StackOverflowError.
  •  Support of both imperative object-oriented and functional programming – in Scala object composition, methods, state encapsulation and inheritance, traits and mixins combined with lazy evaluations, algebraic data types, pattern matching, type classes and, of course, first class functions.
  •  Lots of immutable and mutable, finite and infinite collections with many implemented transformations like map, reduce and filter:

users.filter(_.lastVisitDate before today).map(_.email).foreach(sendNotification)

// Sending notifications to all users that visited our  site   too long ago

  •  Concurrency through mechanisms of actors and futures:

val sum = sumActor ? List(1, 2, 3) // sum == Future(6)

val x = sum.map(_ * 2) // x == Future(12)

  •  Generics – JVM does use type erasure and knows nothing about real types of generics in runtime, but Scala keeps that information.
  •  Compile-time meta programming – in addition to runtime reflection, Scala compiler supports macroses – functions evaluated during compilation.

Distributed Computations and Big Data

One of the fields where Scala found its widest application is distributed computing. Scala has great mechanisms for working with data sequences even in a cluster, which is why it is frequently used by Big Data engineers and data scientists. Here is a list of the most well-known technologies that use Scala:

  • Akka –  a framework for creating distributed systems. It is based on actors model and makes it easier to implement concurrent applications without race conditions and explicit synchronization.
  •  Spark – a very popular batch data processing framework. Spark has integration with different data sources such as Cassandra, HBase, HDFS, and Parquet files. In addition, it has a Streaming extension that provides tools for building stream processing pipelines. One of the most powerful features of Spark is the ability to run quick ad-hoc tasks to check hypothesis. Such functionality is reached by Spark’s design that in some cases gives more than 100 times performance impact in comparison with Hadoop jobs.
  •  Kafka – a high performance message queue, one of the key middleware components in data streaming systems. It is distributed by design and usually acts like a data buffer in streaming systems on the different stages of the processing and as a media between different system parts.
  •  Samza – one more framework for stream processing. It is similar to Spark Streaming but works in a different way. It does not create micro batches as Spark does. Instead, it processes data pieces as soon as they arrive, which makes Samza more preferable in some cases.

In addition to these tools, it is also possible to use Scala for implementing good old Hadoop map-reduce jobs, directly or utilizing Scalding. Anyway Scala is a great choice for data processing and distributed computing.

Compatibility with Java

One more important thing is compatibility with libraries written in Java. Java code can be used in Scala directly and without limitations. This allows to keep existing modules without the need to re-implement them. It could be quite helpful when it is needed to use a rare library, legacy code, or API that have implementations only for Java.

Why Scala?

To sum it up, Scala is well designed and very extensible. It has special processes (SIP and SLIP) that let any Scala developer propose enhancements. In conjunction with the large community, Scala ecosystem has been growing rapidly. Scala has its own stack of tools and is compatible with existing Java code. It brings new effective approaches that give the  programmer an ability to do their job more efficiently. All these features make Scala one of the most attractive modern programming languages.

Which Big Data technology stack is right for your business?

If data analysis is one of the core features of your product, then you probably already know that choosing a data storage and processing solution requires careful consideration. Let’s discuss the pros, and cons of the most popular choices, Redshift/EMR, DynamoDB + EMR, AWS RDS for PGSQL, and Cassandra + Spark.

Managed Amazon Redshift/EMR

Pro – It’s fully-managed by Amazon with no need to hire support staff for maintenance.

Pro – It’s scalable to petabyte-size with very few mouse clicks.
Pro – Redshift is SQL-compatible, so you can use external BI tools to analyze data.

Pro – Redshift is quite fast and performant for its price on typical BI queries.
Con – Redshift’s SQL is the only way to structure/analyze data inside Redshift. It may be easier for simple tasks, but to do complex tasks like social network analysis or text mining (or even running custom AWS EMR tasks) you have to manually export all data to external storage (to S3 for example). You then run all your external analytics tasks, and load results back to Redshift. The amount of manual work will only grow with time ultimately making the use of Redshift an obstacle.
Con – Redshift’ SQL dialect for data analysis used is also very limited (as a tradeoff for its performance), the main drawbacks are: missing secondary indexing support, no full-text search, and no unstructured JSON data support. Usually it’s OK for structured and pre-cleaned sterile data, but it will be really hard to store and analyze semi-structured data there (like data from social networks or text from webpages)
Con – EMR has very weak integration with Redshift: you have to export/import all data through S3.
Con – To write analytical EMR jobs, you have to hire people with pricey Big Data/Hadoop competence

Managed Amazon DynamoDB + EMR

PRO – It’s fully-managed by Amazon with no need to hire support staff for maintenance.
PRO – It’s scalable to petabyte-size with very few clicks of the mouse.
PRO – Pricing is opaque and it may be rather costly to run analytical workload (with full-table scans as for text mining) on large workloads.
CON – DynamoDB is a columnar NoSQL store. For most analytical queries, you have to use EMR tools like Hive, which is rather slow, taking minutes for simple queries that typically execute instantly on Redshift/RDS).
CON – DynamoDB is closed technology which is unpopular in the Big data community (mostly because of its prices). We’ve also noticed difficulty finding people with required competences to extend the system later.

Custom ‘light’ solution with AWS RDS for PGSQL

PRO – Postgresql is easily deployable anywhere, has very large community and there’s a lot of people with required competence. You can use either hosted RDS version, or install your own on EC2 – it does not require any hardcore maintenance (like own custom hadoop cluster) and just works.
PRO – RDS Postgresql supports querying unstructured JSON data (so you can store social network data in a more natural way than in Redshift), full-text search (so you can query user’s friends for custom keywords), and multiple datatypes (like arrays which are very useful for storing social graph data).
PRO – Has full-featured unrestricted SQL support for your analytical needs and external BI tools.
CON – PGSQL is not “big” data friendly. Although versatile for small to medium data, our experience has uncovered difficulties when scaling for large datasets sizes. Scaling may be a serious issue later and require non-easy architectural modifications in the whole analytical backend, but may speed up development if data size is not an issue.

Custom ‘heavy’ solution with Cassandra + Spark:

PRO – Cassandra + Spark can easily handle storing and analyzing petabytes of data.
PRO – Cassandra deals with semi-structured data well, which comes in handy when storing social network data like user’s Facebook wall posts, friends, etc.
PRO – Spark has good machine-learning (for example, dimensionality reduction) and graph-processing (useable for SNA analysis) libraries included. Also has python API to use ant other external tools from numpy and scikit.
PRO – As a self-hosted solution, Cassandra + Spark is much more flexible for future complex analysis tasks.
PRO – Spark has SparkSQL which is an easy integration add-on for external BI tools.
CON – Cassandra may need higher tier competences for challenges that arise when scaling which, in turn, may require additional investment in support staff supervision.
CON – Spark is a rather new technology, but it has already positioned itself well within the big data community as a next-gen Hadoop. At present, it may be hard to find people with Spark competency, but the user community is quickly growing, thus making skills easier to find as time passes.

To Conclude

The final choice is dictated by your current business priorities.

If you need to move forward fast with less maintenance routine and are not afraid of later technical debt, we recommend using the “Light” solution or Amazon DynamoDB. If your top priority is system scalability, then the ‘Heavy’ solution surfaces as the clear choice.

The impact of Big Data is really Big

Data analytics (and big data, as a part of it) is not just an ordinary business tool. It is also not just a buzzword, it deeply impacts almost all modern industries. By the end of 2014 the size of Big Data industry has reached 16 billion, with a forecasted value of 48 billion over the next five years. The fact is that as an innovation point big data has much in common with the invention of the internet – it can revolutionize every industry and affect everybody.  

Many industries benefit from data analysis and here are a few not-so-obvious examples:
  • Farming. With the help of drones farmers are now able to collect precise information about the health of the crops, the level of field hydration and the crops growth dynamics. Analyzing that data, they are able to use fertilizers more economically or build a more effective irrigation system. As a result, production costs decrease and revenue is growing.
  • Film making. Prior to filming its TV series project “House of cards,” Netflix has performed an extensive research, trying to determine, who must be the director (Finch), who must play the main role (Kevin Spacey), and what the plot must be (it is a remake of an older series) in order to hit a certain audience. As its IMDB rating is 9.1, it is safe to say that the analysis was executed well and has contributed to the overall success of the show.
  • Oil extraction. Kaggle has built software that helps oil companies to determine how much to bid on a lease of an oil spot or to determine optimal well spacing. Now oil companies are able to make more informed decisions, resulting in improved operational indicators.
  • Professional athlete training.  Using dozens of different detectors and tools, measuring almost every physical parameter of an athlete – blood pressure, heart rate, body temperature, muscle tension – coaches are now able to detect the best training strategy or even predict athlete’s performance.
  • Fighting crime. The Smart Policing program, implemented in 38 different American police departments, funds and empowers local, data-focused, crime prevention tactics. A key feature of the program is “hot spot policing,” which analyzes geographic patterns to uncover highly likely crime locales. 
Big data and data analysis has potential to improve performance and operations of any business. How has your company been affected by the revolution of big data? With the help of data analytics you can make your product offering more competitive, your services more targeted  and  your next steps in the market more strategic. It is very likely that your competitors are already taking advantage of data analytics that are helping to strengthen their product or service offering. If you haven’t already, it is time to consider what big data and data analysis can do for you.
