Colin Baseman

The twenty-first century is notorious for identity thefts. In the spring of 2018, Mark Zuckerberg was summoned to the US Congress to explain the personal information leakage of more than 87 million Facebook users. This incident led to another round of the need for personal data protection problem.

Opportunities offered by blockchain

Thanks to blockchain, users will be able to store personal information on their own. As well, they will have full control over its disclosure to third parties. That is why there is simply no more need to trust the information to other organizations. Personal data will be protected by cryptographic encryption.

The blockchain technology implementation allows storing personal information only on the user's devices without using remote servers. They can set the access levels to the data.

Government organizations using blockchain technologies will be able to standardize the digital documentation release, as well make processes of use, update and withdraw easier. They often set requirements to undergo KYC procedure for product and services suppliers. As a result, the suppliers must undergo the process of verifying their identities, usually with the help of some special documents. A number of services require customers to scan their passport and send a photo of them holding the original document.

Modern blockchain developments for document control

Blockchain technology allows you to pass the KYC procedure almost instantly. Decentralized Identity Foundation, IBM and the World Wide Web Consortium are actively developing such solutions.

The non-profit organization ID2020 together with world-famous companies Hyperledger, Microsoft, UNICC and others develops personal identifiers on the blockchain. They are working under way to help 1.2 billion people who do not have any documents confirming their existence. The absence of such documents makes it impossible to receive social benefits and allowance as well as get medical care for children and women. Special difficulties arise when opening a bank account and getting education.

SecureKey company provides passport data storage services for identity verification purposes to banking organizations, governments and service providers. Thanks to blockchain, users will have total control and will be able to avoid the need to create central personal information repositories, which are often attacked by hackers.

The Sovrin Foundation service allows creating personal identifiers that may include passports, driver's licenses, air tickets and other documents. It acts as a reliable protection for the customers.

As you can see, the blockchain document flow is no longer a rarity. Many projects are already built on smart contracts
