Access control systems
First Claim
1. A method comprising:
- receiving optical data from an optical sensor, the optical data being associated with an object presented to the optical sensor, wherein the object comprises optically-detectable, machine-readable indicia encoded using digital watermarking, said indicia comprising an orientation component and an identifier;
determining, at a electronic processor a series of orientations of the orientation component;
transmitting the identifier to a server;
receiving a series of expected orientations based on the identifier;
comparing the series of expected orientations with the determined series of orientations; and
determining an access status based on the comparison.

Abstract
The present invention relates generally to access control. One claim recites a method of determining whether to allow access to a location, including: receiving optical data from an optical sensor, the optical data being associated with an object presented to the optical sensor, wherein the object comprises optically-detectable, machine-readable indicia encoded in a predetermined symbology thereon, the indicia including at least an orientation component; determining an orientation of the orientation component; obtaining from a data store a predetermined orientation; and comparing the predetermined orientation with the determined orientation to decide whether to allow access to the location. Of course, other claims are provided as well.
