Abstract
A system and method for receiving secure data in a client device. In one embodiment, the method comprises (a) receiving a token having a token ID and a digital certificate generated by a certificate authority (CA) having client device fingerprint data generated from client device parameters, (b) accepting a request in the client device to provide secure data to the client device, (c) regenerating the client device fingerprint data from the client device parameters, (d) determining, in the client device, differences between the client device fingerprint data of the digital certificate from the regenerated client device fingerprint data, and (e) transmitting a request to a secure data service to provide secure data based upon the determination.
