Abstract
The present disclosure relates generally to identification documents and related methods and apparatus. One claim recites a method to determine whether to authenticate an identification document through digital watermarking or through an alternative process. The method includes: receiving data carried by the identification document corresponding to a detection trigger; if the received data indicates an expected presence of digital watermarks, attempting to authenticate the identification document by analyzing digital watermarking carried by the identification document; and if the received data indicates an expected absence of digital watermarks, attempting to authenticate the identification document through an alternative process. Other claims and combinations are provided too.
