Appl. No.:

12/540241

Inventors:

Douglas H. Trotter - Baltimore MD, US

Michael D. Beck - Bethesda MD, US

International Classification:

H04L 9/32
G06F 15/16
G06F 21/20
G06F 17/00

US Classification:

713182, 726 4, 709203, 235375

Abstract:

A system for secure, role-based exchange of information between a client and providers of services is described. The system includes a client device having a memory that includes a portion of the data relating to the client, a user access component, and an enforcement agent. The system also includes a central server running an authentication methodology and a roles server. The central server includes the data relating to the client. The system further includes an interface device capable of communications with the central server and capable of communicative coupling with the client device. The system is operable to, upon a communicative coupling between the interface device and the client device, activate the user access method, in conjunction with the authentication method, to ensure that the client is the proper holder of the client device. The enforcement agent is operable with the roles server and user interface input from the client to define access rights to the client data for the providers of services, who also have access to the central server.

International Classification:

G07C 9/21
G07C 9/00

Abstract:

A physical access control system enables acceptable portal entry codes upon receiving each physical access request by operating on the elapsed time from a previous physical access request to generate a temporal credential. The controller receives a plurality of physical access requests from a plurality of mobile application devices. Upon authenticating the first access request, the controller eliminates repetition from the space of acceptable successor requests from each mobile application device. Monotonic nonces advance the range of temporal code matches. Entry code generation is decentralized to distributed application devices and is inherently unknowable until a successor access request is initiated by the same application device.
