Title: Innovations by Toshiyuki Ishiguro
Introduction
Toshiyuki Ishiguro is a notable inventor based in Ota, Japan. He has made significant contributions to the field of encryption technology, holding 2 patents that showcase his innovative approach to security and data verification.
Latest Patents
Ishiguro's latest patents include a method for relational encryption for password verification. This method involves receiving a relational key and a registration ciphertext, which is stored without decryption. Upon receiving an authentication request, the method communicates a safeguard data set that includes a random challenge. It verifies the relationship between the encrypted response and the registration ciphertext without decrypting either, ensuring equality between the first and second plaintext data sets. Another patent focuses on relational encryption, which processes biometric data to a level of randomness and encrypts it using a relational linearity encryption scheme and a relational proximity encryption scheme. This method communicates the generated ciphertexts to an authentication server, which then provides an authentication signal indicative of the relationships between the ciphertexts.
