Systems and methods for providing authenticity, integrity, and non-repudiation to advertising technology

A system for providing non-repudiation and data integrity of communications in ad sales online, the system comprising one or more servers communicably connected to a communications network, the one or more server including at least one processor configured for:

• providing a blockchain comprising a public key infrastructure including public keys of parties against which a plurality of cryptographic proofs of said parties may be authenticated;
• wherein the public keys of parties comprise a public key associated with the first party;
• receiving, from a first party, an ad request for an ad impression available for sale, wherein 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;
• authenticating non-repudiation and data integrity of the ad request by querying the blockchain;
• wherein the authenticating comprises authenticating the first cryptographic proof against the public key associated with the first party;
• wherein the first cryptographic proof comprises a third cryptographic proof of the first party;
• and
• wherein the public key infrastructure authenticates the third cryptographic proof against the public key associated with the first party;
• accessing a database of second parties seeking to purchase ads online, wherein the database stores attributes associated with each second party;
• matching the ad request with a selected second party in the database based on the attributes associated with each second party in the database and the attributes associated with the ad impression of the ad request;
• and,
• transmitting, to the first party, a message comprising an ad for the selected second party and a second cryptographic second proof that provides non-repudiation and data integrity of the message, so as to fill the ad impression with the ad for the selected second party.

• providing a blockchain comprising a public key infrastructure including public keys of parties against which a plurality of cryptographic proofs of said parties may be authenticated;
• wherein the public keys of parties comprise a public key associated with the first party;
• distributing a separate cryptographic key to each of a plurality of parties and creating a separate space on the blockchain corresponding to each of the plurality of parties, such that each of the plurality of parties may edit its corresponding space on the blockchain using a cryptographic key received from the system;
• receiving, from a first party, an ad request for an ad impression available for sale, wherein 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;
