Abstract: Examples disclosed herein relate to authentication based on data content and data partitions. In one implementation, a processor may execute instructions to determine the likelihood of authenticity based on partitions of the authentication data and content of the authentication data. The processor then outputs information related to the likelihood of authenticity.

Abstract: Examples of methods for fiducial location are described herein. In some examples, a method may include estimating a first location of an unidentified fiducial based on image coordinates and grid coordinates of a set of contiguous fiducials. In some examples, the method may include determining that a candidate fiducial is a fiducial based on comparing the first location with a second location of the candidate fiducial.
