Abstract
Logic on a first remote device receives a first transaction number and personal data transmitted from a second remote device. The first transaction number was received from a distributed public database in response to a transmission, from the second remote device, of a signed hash value and a first public key associated with a first private key on the second remote device. The signed hash value was created by signing a hash value with the first private key and the hash value was generated by hashing the personal data with a hashing algorithm on the second remote device. The logic uses the first transaction number to retrieve the signed hash value and the first public key from the distributed public database. The logic hashes the personal data using the hashing algorithm to create a generated hash value and verifies the signed hash value against the generated hash value.
