Abstract: A method for auditing an advertisement impression in which a first advertisement was presented in conjunction with first media content is disclosed. The method generally comprises transmitting to a plurality of second computing devices a plurality of randomly generated first cryptographic proofs; receiving, a first message from a second computing device indicating that the first advertisement was presented in conjunction with the first media content; and evaluating the first targeting model for the first advertisement based on the at least one media content classifier.

Abstract: A mechanism by which a secure, privacy preserving query system may be constructed from blockchain technology is disclosed. This system operates on the local differential privacy model through random responses using a private weighted coin protocol. The system specified allows for the ejection of malicious and/or non-interactive participants, minimizes blockchain storage size, and provides a mechanism for forward secrecy. The system specification uses a distributed random beacon to provide a public source of randomness. This randomness is utilized to perform random subset selection from a publicly known list of participating entities. The system uses a homomorphic self-tallying voting protocol under homomorphic encryption to further ensure participant privacy.

Abstract: A system and methods are disclosed that enable advertisers, publishers, and consumers to interact to provide well-targeted advertisement impressions, while preserving consumer privacy. Particularly, the system and methods enable accurate and reliable targeting of advertisements without the need for privacy-invasive tracking and collection of consumer information by advertisers or publishers. Instead, the consumer retains complete control of his or her own private information, even while that private information is used for programmatic targeting of advertisements. The system and methods disclosed herein advantageously utilize blockchain as a tool for arbitrating data, which accounts for and helps to eliminate fraud, costly arbitrage, and brand safety concerns by providing the programmatic advertising ecosystem with trust, permanence, transparency, and auditability.

Abstract: 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.

Abstract: A system for providing authenticity, integrity, and non-repudiation to advertising technology. At least one processor receives an ad request for an ad impression available for sale. The ad request includes attributes associated with the ad impression and a cryptographic proof that provides non-repudiation and data integrity of the ad request. The ad request is authenticated by querying a blockchain. The processor accesses a database of second parties seeking to purchase ads online. The database stores attributes associated with each second party, matches the ad request with a selected second party based on the attributes associated with each second party in the database and the attributes associated with the ad impression of the ad request. The processor transmits to the first party a message having an ad and a cryptographic proof of the message, so as to fill the ad impression with the ad for the selected second party.
