Latest Patents
One of Saarepera's latest patents is a digital signature system using scalable servers. This system includes scalable frontend servers that communicate with application servers and scalable backend servers that interact with remote security devices. When a user registers with the system, their remote security devices are assigned to a backend server. A total public key is generated by cryptographically embedding the unique identifier of the assigned backend server into a combined public key associated with the remote security devices. This innovative approach ensures secure and efficient processing of signature requests.
Another notable patent is for verifiably unique transfer of exclusive control of data units. This invention allows for the exclusive ownership of data units, such as monetary units, to be transferred securely. The process involves inputting a request from a transferor to a transferee, including identifiers for both parties and the designated data unit. The system verifies the transferor's identity and confirms that no other transfer requests exist during the update period. Ownership is then changed in a ledger configured as a blockchain, allowing for per-unit processing instead of per-account.
