PHYSICAL ACCESS CONTROL USING DYNAMIC INPUTS FROM A PORTABLE COMMUNICATIONS DEVICE

摘要

Methods and apparatus for controlling access to a secure facility (100) are disclosed, wherein a determination of whether access is permitted is based at least in part on a digital image (210) of one or more predetermined features of the secure facility (100). In an exemplary method, an image (210) of a predetermined feature of the secure facility (100) is captured by a user device (200, 700) and compared to stored security data corresponding to the secure facility (100). A determination of whether access to the secure facility (100) is permitted is made, based on the results of the comparison. The predetermined feature may be a security mechanism (120) attached to the secure facility, for example, or may be textual information, a graphical image, or a machine-readable code (132) posted at the security facility (100).
