Patent ID: 8762731

Claim:
A computer system including instructions recorded on a computer-readable medium and executable by at least one processor, the system comprising: a multi-system manager configured to cause the at least one processor to perform state change calls to one or more backend systems by combining a multi-system protection token with a message component for transporting from a user agent to the one or more backend systems for validation, wherein the multi-system manager includes: a symbol generator configured to generate an authentication code for proving authenticity of a combined data structure generated by combining a secret cryptographic data key with a portion of the message component and generating a hash code of the combined data structure; a nonce generator configured to generate an arbitrary random number to bind the multi-system protection token to the user agent; and a token generator configured to generate the multi-system protection token by combining the authentication code and the arbitrary random number with the message component for transporting from the user agent to the one or more backend systems for validation.
