Kaspersky Lab has received a patent from the U.S. Patent and Trademark Office for a blockchain technology that facilitates the process of data management and ensures their legal transfer and processing. It also solves the task of authenticating the parties involved in the data transfer process and ensures the confidentiality of the transmitted information. Previously, the technology was patented in Russia,” the press service reported.

The patent was called “Systems and methods for sending user data by a trusted party to a third party with using a distributed registry,” the company explained. We are talking about methods of protecting personal data from illegal transfer and processing.

“The technology is of particular value for service providers who are obliged to comply with the requirements of Know Your Customer (KYC) and Client Due Diligence (CDD), the purpose of which is to reduce customer risks and track financial transactions. Companies can refer to transaction records in the blockchain network to confirm the consent of subjects to transfer and process personal data in case of problems with the legitimacy of these processes,” the company explained.

The patented methods ensure that the data log contains only information related to the facts of the transfer of personal data and the consent of the subjects to this process, the “Laboratory” stressed. All records are contained in the form of hashes, which are signed and encrypted in a unique, patented way. “This approach avoids leaks and uncontrolled data transmission, since it makes it possible to use entries in the registry only to direct participants – the sender, recipient and owner of the information,” the company added.

The technology can also be used in other scenarios, for example, when exchanging shipping documents or confirming an employee’s authority to sign a document with an electronic signature, the company added.
