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