SYSTEMS AND METHODS FOR PROVIDING AUTHENTICITY, INTEGRITY, AND NON-REPUDIATION TO COMMUNICATIONS ONLINE

摘要

A system for providing non-repudiation and data integrity of communications online is shown and described. The system has one or more servers communicably connected to a communications network, the one or more server including at least one processor configured for receiving, from a first party, an ad request for an ad impression available for sale. The ad request includes a plurality of attributes associated with the ad impression and a first cryptographic proof that provides non-repudiation and data integrity of the ad request, wherein the first cryptographic proof comprises a second cryptographic proof of the first party; and, authenticating non-repudiation and data integrity of the ad request by querying a blockchain having a public key infrastructure. The public key infrastructure also has a public key associated with the first party. Furthermore, the public key infrastructure authenticates the second cryptographic proof against the public key associated with the first party.
