System and method for homomorphic ancillary document data encryption, data authentication, and data transfer

Abstract

Systems, computer program products, and methods are described herein for homomorphic ancillary document data encryption, data authentication, and data transfer. The present disclosure includes receiving an interaction event from a terminal device, receiving, upon a first condition where the resource transfer card comprises an embedded document card comprising at least one document data file, a network check comprising a document data file trigger, retrieving, from the resource transfer card, the at least one document data file, encrypting the at least one document data file using a homomorphic encryption protocol, transmitting the at least one homomorphic encrypted document data file, receiving a signal comprising an authentication credential associated with a cardholder of the resource transfer card, recording the authentication credential, and transmitting a decryption key configured to decrypt the at least one homomorphic encrypted document data file.
