US Patent 9762564 Acquiring client device data

In one implementation, a processing system receives a request from a client device to access a user account of the user. In response to receiving the request, the processing system transmits credential data, which corresponds to a credential and which indicates client device data to transmit in response to receiving the credential data. The processing system receives the client device data from the client device, identifies an issuer of the credential, and transmits the client device data to the issuer of the credential.
