Sony Requests Blockchain Patent for User Authentication System

Sony may be looking to use a blockchain in a user login system, according to a new patent application.

Released by the US Patent and Trademark Office on October 26th, the document describes how the electronics manufacturer can use two different blockchains platforms in conjunction with one another as part of a multi-factor authentication (MFA) system.

MFA systems work by giving users two different credentials to log into a site or program. After a user enters a default user name and password, an authentication token generates a code, which they must also enter to gain access. The idea is that although an attacker can get a user’s password, they usually can not access the token, which generates a different code for each login.

According to Sony’s application, one of its proposed blockchain platforms would create these authentication codes, while the other would receive them to confirm the identity of a user when attempting to make a transaction through the platform. Possible transactions include data transfer, contract generation, and asset transfer, according to the application.

Earlier this year, Sony announced an educational platform it is developing in conjunction with IBM, poised for a release next year. The platform will use a blockchain to store students’ records securely, with the idea that the technology can provide additional transparency for stakeholders.

The company said in a statement that it plans to continue seeking use of blockchain technology for different fields, including in the supply chain and logistics, indicating other areas where proposed intellectual property could be applied.
