Verification data processing system and verification data processing method

The invention provides a certificate data processing system and method, in which a plurality of electronic signatures are received within a time interval, and each of the electronic signatures is generated by processing and encrypting original data according to a private key of an electronic certificate. In the proof data processing method, after the time interval, a Merkel tree is generated according to the plurality of electronic signatures, and a token for each of the electronic signatures is generated. Each token records a Merkel root of the Merkel tree, each electronic signature, an electronic certificate corresponding to each electronic signature, a Merkel proof corresponding to each electronic signature, and a timestamp set.
