A computer implemented method for identifying and linking a data originator and a data file or data batch from the originator through one or more data source systems. The system stores the data files and batches on a permanent basis for subsequent verification purposes, verifying the identity of the data file originator through originator-specific information from the data source system; and generating unique data entries associated with the originator identity, the file identity and/or a file verification cryptographic digest, and a unique originator signature. The data entries and signature are stored in encrypted form in a Relay Access Table (RAT), as are the public and private keys associated with both the data file and the originator. A certificate for verification of the data file is generated, that contains a digital signature, as well as a file cryptographic digest and metadata associated with filing conditions. |
