More Information
Summary:Methods, systems, and computer media provide attestation tokens that protect the integrity of communications transmitted from client devices, while at the same time avoiding the use of stable device identifiers that could be used to track client devices or their users. In one approach, client devices can receive anonymous certificates from a device integrity computing system signifying membership in a selected device trustworthiness group, and attestation tokens can be signed anonymously with the anonymous certificates using a group signature scheme. Client devices can include throttlers imposing limits on the quantity of attestation tokens created by the client device.
