ACCESS CONTROL METHOD, SYSTEM, DEVICE, TERMINAL, AND COMPUTER PROGRAM PRODUCT USING MULTIMODAL AUTHENTICITY DETERMINATION

Aspects of the present invention are directed to access control method, system, device, terminal, and computer program product for controlling access to an identity-based access-controlled resource using multimodal authenticity determination for an object of authentication at an access point located in the access-controlled resource. First and second authenticity scores are determined from information on facial recognition and fingerprint authentication modalities. Based on the acceptability of each of the first and second authenticity scores, a third authenticity score is determined from a digital key authentication data uniquely identifying input data associated with any one of the facial recognition and fingerprint authentication. The digital key is generated based at least in part on a determined distance of at least two unique identifier data in relation to one another. The unique identifier data are included in a subset of unique identifier data overlaid to any of reference input data into which the input data are compared. The subset of unique identifier data is randomly selected from a set of unique identifier data generated from any one or more color identifier data in a standardized color matching system such as the Pantone Matching System which provides unique color values whereby no same digital key can be generated for the object of authentication. The uniqueness of the digital key guarantees high level of authentication.
