Claim 16:
17. A computerized method for generating a multi-signature access token on a network for signature validation, the method comprising:
accessing, by only an authorization service on the network, a first private key of a first key pair and a second private key of a second private key pair, wherein the first key pair includes the first private key and a first public key which are protected at a first keystone using a first security protocol, wherein the second key pair includes the second private key and a second public key which are protected a second keystore using a second security protocol, and wherein the first security protocol and the second security protocol are different security protocols;
generating, by the authorization service, a first signature by applying the first private key to user information associated with a user request that includes request data;
generating, by the authorization service, a second signature by applying the second private key to the user information;
generating, by the authorization service, an access token that includes (1) the user information, (2) the first signature, and (3) the second signature; and
determining whether the user request is authorized based on an analysis of the first signature and the second signature of the access token.
