US Patent 10212144 Digital credential with embedded authentication instructions

Methods and systems are provided for sending messages in a security system. In particular, a new message syntax can include one or more positive assertions that may be verified. The receiver of the message or credential may verify all the positive assertions. In other configurations, one or more nodes that relay the message from the sender to the receiver can verify the positive assertions or may create one or more of the positive assertions. In this way, the network or entities used to relay the message can also be checked.
