A method for authenticating an object, comprising determining a physical dispersion pattern of a set of elements, determining a physical characteristic of the set of elements which is distinct from a physical characteristic producible by a transfer printing technology, determining a digital code associated with the object defining the physical dispersion pattern, and authenticating the object by verifying a correspondence of the digital code with the physical dispersion pattern, and verifying the physical characteristic.

The disclosure provides a device for recognizing an image and a device for reading an image. The device for recognizing the image includes a circuit board (50) on which a plurality of light sources (20) are arranged, the multiple light sources (20) which are configured to supply multiple lights in different directions to the image to be recognized, and an imaging component configured to uniformly image the lights diffused by the image to be recognized so as to recognize the image to be recognized. The disclosure solves the problem that the device for recognizing the image in the relevant technology may only supply one single light emitting direction, and the device for recognizing the image has a beneficial effect of recognizing a hologram including various pieces of image information.

A device for verifying a content of an analog document is provided. The device includes a scanning unit being configured to generate a scan information by scanning the analog document and to store the scan information in a storing element being provided on the analog document, and a verification unit being configured to verify the content of the analog document using the stored scan information. Further, a corresponding method for verifying a content of an analog document is provided. Using the provided device for verifying the content of an analog document, it can be ensured that the content of the analog document is not changed by an attacker. If the content is changed, the verification would fail.

The present invention relates to a method for authenticating a document comprising at least one line of anti-counterfeit patterns spaced from each other, the positions of the anti-counterfeit patterns being random, and a partial anti-counterfeit pattern being provided at an edge line of said document, the method comprising the following steps of:

receiving a digital image of said document, said digital image comprising said partial anti-counterfeit pattern in a first edge area corresponding to said edge line;

selecting said first edge area;

copy-pasting said first edge area adjacent to a second edge area of the digital image to generate a combined digital image, said second edge area being opposite to said first edge area, wherein content, which is comprised in said second edge area and located on the same line as said partial anti-counterfeit pattern, and said partial anti-counterfeit pattern jointly form a combined pattern;

authenticating said document by taking into account said combined pattern.
