OBJECT AUTHENTICATION DEVICE AND METHOD

摘要

The present invention discloses a device for authentication, which is capable of producing a topographic pattern image based on a microstructure of a paper-based artifact. The topographic pattern image of the microstructure of the paper-based artifacts is used for authentication of the paper-based artifacts. The device is characterized by an illumination channel (100) comprising a light source (110) and a light director (120) configured to bend the light beam produced by said light source. The device also includes an imaging channel (130) comprising at least one lens (140) configured to magnify the topographic pattern created by the light beam and an image capturing mechanism (150) to capture said topographic pattern.
