Method and system for verification of identity attribute information

Abstract:

A method for verification of a data value via a Merkle root includes: storing, in a memory of a processing server, a Merkle root; receiving at least a data value, a nonce, and a plurality of hash path values; generating a combined value by combining the data value and the nonce; generating a first hash value via application of a hashing algorithm to the combined value; generating a subsequent hash value via application of the hashing algorithm to a combination of the first hash value and a first of the plurality of hash path values; repeating generation of the subsequent hash value using a combination of the next hash path value of the plurality of hash path values and the most recent subsequent hash value; and verifying the data value based on a comparison of the Merkle root and the last generated subsequent hash value.
