Described are various embodiments of a cryptographic process for portable devices, and user presence and/or access authorization systems and methods employing such protocols. In one embodiment, a digital user authentication system is described to comprise a wireless digital user authentication device (UAD) operable to authenticate the user and wirelessly communicate an authenticated identity thereof; and a network application operatively associated with a wireless access point and operable to authenticate the user presence. Upon the network application authenticating the user presence based, at least in part, on the authenticated identity, the UAD and the network application securely establish a short-term symmetric advertising (STSA) key. During a prescribed advertising lifetime of the STSA, the UAD periodically computes and advertises authentication codes encompassing the STSA key so to securely advertise the authenticated user presence.

Cryptographic process for portable devices, and user presence and/or access authorization system and method employing same

Described are various embodiments of a user activity-related monitoring system and method, and a user access authorization system and method employing same. In one embodiment, a system is provided for authenticating a user authorised to perform a designated activity in a designated environment. The system comprises a wireless digital user authentication device (UAD) operable to: wirelessly establish an authenticated access session at an access point within the designated environment for performing the designated activity; and acquire activity-related data during performance of the designated activity. The system further comprises a digital application operatively associated with the wireless digital UAD and operable to: digitally compare and evaluate compliance of the activity-related data with a digital authenticated activity template within a designated tolerance.

User activity-related monitoring system and method, and a user access authorization system and method employing same

Described are various embodiments of a system for monitoring a physical user presence during an authenticated user access session at an access point. In one embodiment, the system comprises a wireless digital user authentication device (UAD) operable to wirelessly establish the authenticated user access session, periodically communicate an authenticated presence code to actively maintain the session and acquire motion-related data during the session to capture a UAD departure motion representative of the user departing from the access point. The system further comprises a digital application operatively associated with the access point and operable to wirelessly establish the session with the UAD upon arrival at the access point, and periodically receive the authenticated presence code to maintain the authenticated user access session. The authenticated user session is terminated upon identifying the UAD departure motion from said the motion-related data.
