Claim:
1. A computer-implemented method to control access to functions of a resource, comprising: establishing, by an access manager of a resource, enrollment information (e) for each of a plurality of users; encrypting, by the access manager, each received enrollment information (e) in an authorization data item for the corresponding user; transmitting, by the access manager, each authorization data item to a user computing device of the corresponding user; receiving, by a control point of the resource, from a user computing device having received a transmitted authorization data item, a request for access to a function of the resource, the request for access comprising the received authorization data item and verification information (v); decrypting, by the control point, the received authorization data item to extract enrollment information (e); determining, by the control point, a similarity measure between (v) and (e); for a determined similarity measure greater than or equal to a threshold, authorizing, by the control point, the request for access; and for a determined similarity measure less than the threshold, denying, by control point, the request for access.
