Our money is transferred instantly via virtual bank accounts. Our informational sources are vast and thorough. Even online orders are delivered the next day. But the amazing expediency of the digital age comes with a cost. Namely, our privacy.

Our dozens of accounts spread throughout the web and protected only by often weak passwords include bank accounts, health records, birthdays, social security numbers and passport information.

Blockchain Cybersecurity Uses

  • Maintaining cryptocurrency integrity
  • Securing banking assets
  • Protecting patient health records
  • Revamping government cybersecurity protocols
  • Safeguarding military and defense data
  • Fortifying Internet of Things (IoT) devices

The information age explosion of online data has brought with it lapses in security protocols that regularly expose our most sensitive information to malicious actors. Finding a reliable cybersecurity protocol, therefore, is more important than ever before. 

Industries across the board are latching onto new technology that promises to improve online safety, with blockchain cybersecurity leading the way.

 

Blockchain: A New Weapon in Cybersecurity 

Cybercrime is such a vast and burgeoning underworld industry that it prompted Ginni Rometty, Chairman, President and CEO of IBM, to declare that “cybercrime, by definition, is the greatest threat to every profession, every industry, every company in the world.

Both dangerous and costly, cybercrime costs the global economy an estimated $445 billion per year. Our current security protocols simply cannot keep up with the relentless and clever attacks.

Blockchain, a Distributed Ledger Technology (DLT), is focused on creating trust in an untrusting ecosystem, making it a potentially strong cybersecurity technology.  

The ledger system is decentralized, but information is transparently available to members of the specific blockchain. All members (or nodes) can record, pass along and view any transactional data that is encrypted onto their blockchain.

This process creates trust while also maintaining a high level of data integrity. In essence, the distributed nature of blockchain provides no “hackable” entrance or point of failure that detrimentally exposes entire datasets.

The cybersecurity industry can benefit from blockchain’s unique features, which create a virtually impenetrable wall between a hacker and your information.

The transparent ledger allows for password-free entry. Using biometrics, including retina scans and fingerprints, the ledger can create a single-source, uncrackable form of entry into any private data.

Decentralized storage ensures that each block contains only a small informational piece to a much larger puzzle, limiting hackable data to almost nothing.

Finally, blockchain’s public record-keeping system gives each node an insight into any data manipulation, exposing potential cybercrime attempts in real time.

Blockchain in cybersecurity is widespread, and we’ve rounded up six industries that use it as a new weapon in the fight to protect our most sensitive information.

 

Blockchain and Cryptocurrency Integrity

First implemented as the operational network behind Bitcoin, blockchain is now used in more than 1,000 different cryptocurrencies, a number that grows almost daily.

DLT protects the integrity of cryptos through encryption methods and public information sharing.

The legitimacy of cryptocurrency purchases by individuals is ensured because they can trace the transfer of the currency to its origin. Encryption helps control the number of cryptocurrencies being created, thus stabilizing value.

These four companies use blockchain as a cybersecurity protocol in cryptocurrency trading.

Coinbase is an exchange for users to buy and sell digital currency. Users can trade everything from Bitcoin to Litecoin to Ethereum on the company’s secure blockchain platform. Coinbase runs entirely on encryption. The company stores wallets and passwords in a secure database and requires employees to undergo a rigorous background check, all to ensure that their crypto is safe.

 

Location: San Francisco, California

MobileCoin develops an easy-to-use cryptocurrency for resource-constrained businesses that aren’t currently equipped to securely handle ledger information. The company’s crypto replaces third-party transaction vendors, and it keeps all transactional data between two peers encrypted. The boosted level of security helps companies keep transparent records in the public sphere.

Founders Bank aims to be the world’s first decentralized bank. Instead of being owned by a central authority, the bank is owned by purchasers of its token-based equity.  The company employs decentralized storage methods, an extensive public ledger system and encryption methods to make sure cryptocurrencies are traded and stored securely.

 

Banking and Blockchain

Wall Street has begun to take notice of blockchain’s bolstered security protocols. Traditionally known as slow movers in adopting new technologies, some of Wall Street’s largest financial institutions (including JP Morgan and Bank of America) are trying to stay ahead of the curve. JP Morgan Chairman and CEO Jamie Dimon said the bank has been looking at blockchain for solutions to cybersecurity issues.

Trillions of dollars in cash flow combined with outdated and centralized cybersecurity protocols make the largest banks constant targets of hacking and fraud. In fact, most multinational banks currently experience cyber attacks daily, with cyber criminals focused on operational risks. In its annual report, the US Office of the Comptroller of the Currency (OCC) said more sophisticated phishing attacks target employees who have access to credentialed information. The report suggests a multi-layered security protocol to decentralize risk — exactly what blockchain can provide. Here are three early adopters among “traditional” Wall Street banks that use blockchain technology to guard their most important data.   

 

Location: New York, New York

JPMorgan Chase, the largest financial institution in the U.S., has developed an enterprise-focused version of Ethereum called Quorum. The platform uses blockchain technology to process private transactions. The bank uses smart contracts on the Quorum network to implement transparent yet cryptographically assured transactions.

 

Location: Boston, Massachusetts

Santander was the first bank in the UK to adopt blockchain to securitize their international payments service. The bank’s blockchain enables customers to securely pay between Santander accounts in Europe and South America. In partnership with Ripple, Santander’s “One Pay FX” is now live in Spain, the UK, Poland and Brazil.

 

Location: London, England

Barclays filed a patent that would use blockchain technology to bolster security in fund transfers. The Wall Street bank is possibly looking to boost the popularity and stability of cryptocurrency transfers while using DLT to process these transfers. Along with its blockchain fund transfer patent, Barclays has a patent for know-your-customer processes that enables the bank to store all personal identifying customer information on a secure blockchain.

Patient Health Records and Blockchain

Like banking, the healthcare industry endures a constant barrage of cyber attacks. In fact, healthcare experiences twice the amount of phishing emails and malware attacks of any other industry. New challenges arise constantly and now include cyber-attacks on IoT devices that are disguised using encrypted malware.

Not only do healthcare companies, hospitals, doctors and clinics store patient banking information, they also possess important health records. Patient data is important to cyber criminals because it demands much more money on the black market — up to $250 per record. Credit card information is constantly stolen, but modern technology typically resolves any damage quickly. Exposing the social security numbers, full names, weights, heights, prescriptions and medical conditions of millions of patients can be detrimental. By threatening to release confidential information, hackers have already extorted millions of dollars from hospitals all over the world and will continue to do so unless new technologies are implemented.

Blockchain could be the badly-needed solution to a problem that puts patients and hospitals at severe risk. The DLT’s decentralized state allows only certain individuals to have small amounts of information that, if combined, would comprise a patient’s entire health chart. The distribution of only certain information to credentialed healthcare professionals ensures that cybercriminals cannot access all identifiable aspects of an individual’s health record.

Blockchain and Military and Defense Data

Innovation within the military and defense sectors has led to some of the biggest technological breakthroughs in the past century. The U.S. military pioneered the Internet to share important detailed information with dispersed groups all over the world, and it created GPS to better grasp military positioning. Will blockchain be the next breakthrough technology that’s promoted by the defense sector?

According to Accenture, 61 percent of aerospace and defense companies have adopted blockchain solutions. Blockchain is seen as a legitimate data safeguard for militaries, defense contractors and aerospace companies that house some of the most sensitive information.

These militaries and defense companies use blockchain’s encryption and decentralization methods to improve data security and maximize privacy.

Internet of Things (IoT) Security and Blockchain

The Internet of Things (IoT) is a growing industry full of innovation, creativity and, consequently, cybersecurity issues. Nowadays, IoT products can be found in almost every aspect of our lives. From robo-sprinklers to Bluetooth-enabled bike locks to smart kitchen appliances, everything is wirelessly connected.

There have been thousands of reported IoT device hacks over the last few years, a number that will surely increase in light of estimates that there will be over 55 billion connected IoT devices by 2025. One cybersecurity-related report found that hackers were able to bypass the security measures in an implantable cardiac device, which gave them the ability to deplete the battery as well as administer incorrect heart shocks. Additionally, it was reported that hackers targeted the camera of a “smart” baby monitor by obtaining a simple IP address. The hackers had full control of the machine to watch through the camera and listen in on conversations.

As the IoT device market continues to grow, so too does the need for an enhanced form of cybersecurity. Blockchain provides a safe infrastructure for the transfer of data from one device to another without the interference of malicious actors. Decentralized control enables IoT devices to create audit trails and tracking methods for registering and using products.

These four companies are focusing on diminishing hacking opportunities and maximizing cybersecurity strength within the Internet of Things.

Blockchain and Government Cybersecurity Protocols

The Office of Management and Budget (OMB) published a damning report on the U.S. Government cybersecurity infrastructure, where phrases like “do not have the resources to combat the current threat environment” and “agencies lack visibility into what is occurring on their networks” are only the beginning.

The porous security can be improved with blockchain. The entire system runs on safe encryption of information, essentially putting a barrier between hackers and identifiable information. Encrypted data, decentralized information storage and publicly-visible ledgers can instill a new set of government cybersecurity priorities. Agencies would be able to quickly identify potential hacks and trace the manipulated data to its origin. These governments and agencies, in attempting to be among the first governmental blockchain adapters, are pioneering ways to implement DLT into everyday cybersecurity protocol.       

 

The State of Colorado

Location: Denver, Colorado

The Colorado Senate passed a bill in May 2018 that implores the government to consider blockchain for data protection and the secure storage of records.
