Abstract: A method for enabling a verifying party to verify an identity of a target comprising a target party or device. The method comprises, in a set-up phase 702, by a party other than the verifying party: inputting a set of one or more challenges into a PUF module associated with the target party and comprising a physically unclonable function (PUF), in order to generate a respective set of one or more responses based on the PUF; and storing a respective response data record for each of the set of responses in a data store external to any equipment of the target party or verifying party, the data store either being part of third party computer equipment or being a public peer-to-peer publication medium e.g. a blockchain. The response data records are thus made available to the verifying party to verify the identity of the target in a subsequent verification phase 704. Instead of storing the actual responses, the record could include an attestation of the response e.g. a signed hash, or a public/private key pair generated from the response.

Title: Systems and methods for privacy preserving determination of intersections of sets of user identifiers
Inventor: Michael William Daub
IPC: G06Q30/02
Filed: 2020-05-29
Abstract: At least one aspect is directed to determining an estimate of an intersection of user identifiers in a first set of user identifiers and a second set of user identifiers. The first and second sets of user identifiers can be populated with user identifiers that have interacted with the same content item or content item campaign. Estimates of intersections of the first and the second sets can be determined based on a binomial vector approach, a vector of counts approach, or a hybrid approach. The binomial vector approach generates vectors based on k hashes of each user identifier in the first set and summing the vectors to generate a first vector. The intersection can be determined based on a dot product of the first vector and a second vector similarly generated from the second set of user identifiers.
