摘要： Systems and methods applicable, for instance, to the generation and usage of authentication images. In one aspect, unauthorized attempts to duplicate authentication images can be thwarted. In another aspect, there can be provision for authorized authentication image generation using low-resolution print devices.

摘要： An authentication system includes an object including an authentication hologram disposed over an area of a surface of the object. The authentication hologram is defined by a pattern of reflective material and includes latent authentication information. The system includes a computer-readable medium including program instructions for execution by one or more processors. The program instructions are executable by the one or more processors to: (i) receive, from an image capture device, a digital image of the authentication hologram, wherein light reflected by the reflective material is captured in the digital image of the authentication hologram, and (ii) detect the latent authentication information in the digital image of the authentication hologram, wherein an effect of the reflected light is reduced to detect the latent authentication information.
