An identification device includes: an observation object shape frame display configured to display, on a display screen, an observation object shape image indicating a shape of an anti-counterfeit medium observed at an observation angle, and display image data that is an image of an imaging object of an image-capturing device, the anti-counterfeit medium being designed such that an observed pattern of light varies as the observation angle varies; a shape similarity calculator configured to calculate a shape similarity between the observation object shape image and an outer shape of the anti-counterfeit medium; and an imaging determinator configured to perform imaging determination as to whether the observation angle and an observation position of the image-capturing device are correct based on whether the shape similarity is equal to or greater than a shape similarity threshold.

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.

A method is provided for checking a substrate with a specified luminescent substance incorporated and/or applied areally. A substrate luminescent characteristic value for the substrate is ascertained, for which purpose a number N of luminescence intensity values are captured at respectively different locations on the value document, and the substrate luminescence characteristic value is ascertained in dependence on a rank order of the luminescence intensity values. It can be checked whether the substrate luminescence characteristic value meets a specified criterion.

An image identification system for conducting image identification of a valuable file in an automatic teller machine and a corresponding image storage control method are provided. The system comprises: an image sensor; an image memory; an image identification module; an image storage area controller; and a main control unit, wherein the image storage area controller comprises a storage area index link table which is divided into N nodes, N being a natural number greater than 1, each node corresponding to each of the image storage areas divided by the image storage area controller in a one to one relationship, and each node storing the storage locations of a previous image and a next image which are linked with the node, and being provided with an acquired image write pointer, an identified image read pointer, an unidentifiable image head pointer, and an unidentifiable image tail pointer.

A serial number recognition parameter determination apparatus includes: a generation unit, an identification unit, and an evaluation index calculation unit. The generation unit generates a parameter set of a program, the program being used when a paper sheet handing apparatus identifies, from an image of a paper sheet, character present regions in which characters that form a serial number are present. The identification unit identifies, from an image of the paper sheet, the character present regions by using the parameter set that is generated by the generation unit. The evaluation index calculation unit calculates an evaluation index of the parameter set based on the character present regions that are identified by the identification unit.
