Blockchain as a solution for data privacyPexels.com
Blockchain technology has been in the limelight of the recent. The new use cases that spread across multiple sectors were swelling. Governments, large companies and agile startups have implemented successful pilot projects, demonstrating that the blockchain really has a "life" beyond the cryptocurrencies in production, invest and other industries. & Nbsp;
This year has also been complicated from a security point of view. Several data breaches have challenged both users and regulators about how companies should process the data entrusted to them. New compliance requirements have emerged that address user privacy and data collection (GDPR). & nbsp; These two trends seem to merge into a single new one: companies are now thinking about whether the blockchain could be the "magic ball" to deal with data privacy issues.
"Blockchain has the technological foundations to ensure better data security," said Xiaoyang He, founder of Lambda, a secure and scalable decentralized storage network with the mission to promote the decentralization of the Internet.
Blockchain is a decentralized technology, operating like a distributed ledger, shared across multiple devices around the world. All data recorded on that log is stored in a distributed manner, eliminating the single point of failure: the central repository of data that most cyber criminals tend to identify at this time. According to Xiaoyang "Breaking into a single block to steal some recorded information is virtually impossible at this point." Altering or otherwise hindering a string of data inserted into a blockchain-ledger is even less likely. "
Secondly, blockchain technology enabled the new type of storage for virtually any type of virtual resources: legal documents, medical records, payment or identity information. "Once these data points have been encoded and entered into the ledger, there is no way to copy or duplicate such information without the explicit permission of the owner, technologically granted," Xiaoyang explained. "The exchange of such cryptographically protected documents, however, is simple: sensitive information does not" change hands. "The two users simply exchange keys for accessing and revising such information, and one party can revoke that access at any time. "
These & nbsp; "authorized" accesses, powered by the blockchain, are now actively explored as a new solution to stay compliant with GDPR.
Emerging use cases of Blockchain for data privacy
IBM is among the first companies to get on the cart. Last September, the technology giant has presented a new patent for a blockchain-based system that will handle privacy and security issues for drones.
The solution described can be used to manage sensitive data exchanges such as those relating to the position of the drone, its manufacturer and / or model, its flight behavior, the proximity of the vehicle to restricted or forbidden flight areas and further information necessary for regular operations. The patent also indicates that smart contracts can be exploited to "securely" feed additional data to the blockchain system described.
General Motors seems to follow the example. The right company has filed a patent describe how self-driving cars could store all the necessary data on a distributed ledger and exchange it with other entities connected to the system, e.g. authorities, public facilities such as airports and other vehicles participating in autonomous driving on the roads. Clearly, more and more companies are viewing blockchain as a secure data exchange solution for powering IoT devices and "smart" gadgets, which transmit sensitive data.
Lambda further analyzes the value of the blockchain for data privacy. This new one The blockchain infrastructure project addresses decentralized data storage from a scientific point of view, taking advantage of two different approaches: Provable Data Possession (PDP) and Proofs of Retrievability (POR) to create an immutable and secure archiving solution, recording and exchanging large volumes of data between multiple parties. & nbsp; Their platform can be an alternative to local and cloud-based solutions, with an added level of security and transparency. For companies that are subject to stringent compliance requirements, decentralized storage can be a significant lever to stay compliant without increasing operational costs.
MEDREC, a project launched at MIT, pursues a similar goal, but for the health sector. & nbsp; The project is positioned as "a Network, not at service," allowing a seamless exchange of health information between patients and the service provider. Patients can maintain full control of their information and give access to their records to suppliers, rather than the reverse as it is now. Healthcare professionals can join the network and make patient data available on request, with patient permission. They have already managed a number of pilot projects with research partners and are currently working on further improvements. Solutions similar to MedRec can reduce the numbers and costs of health data breaches, continuing to reign in the industry and fueling the development of new HIPAA compliant EHR solutions.
Blockchain has significant potential to change data transactions in the future, making them more secure and based on permissions. The successes are still too early to be defined as definitive, but they certainly demonstrate what we can expect when the blockchain will eventually move from the margins to the mainstream.
