Problems solved by technology

[0007] However, in this case, since the identification of the paper type is performed based on the entire image data, it is easily affected by the inconsistency of the characteristics of the machine and the paper type, so the reliability of the data accuracy is low.
In addition, since all the data for collation judgment is required to identify the type of paper, it is necessary to have a huge amount of data storage.

Embodiment Construction

[0034] Embodiments of the present invention will be described below with reference to the drawings.

[0035] Accompanying drawing represents the document authenticity identification device for identifying the authenticity of documents such as driver's licenses, such as figure 1 As shown, the document authenticity identification device 11 is provided with a loading surface 13 for placing documents such as a driver's license on the top of a cuboid device body 12, and an openable single-openable opening and closing cover 14 is arranged on it. .

[0036] The mounting surface 13 has an image data acquisition function of optically detecting display data using transmitted light and reflected light to obtain image data for identifying the authenticity of the driver's license.

[0037] In order to acquire the image, a flat glass surface is provided, the driver's license is placed on the glass surface with the front of the driver's license facing down, and this part is set as the image...

Abstract

The present invention has its object to provide a document authenticity discriminating apparatus and a document authenticity discriminating method, in which authenticity can be discriminated with high accuracy at the time of discriminating authenticity of a presented document by acquiring picture images making use of a wavelength characteristic with respect to transmissivity and reflectance of light, and subjecting the acquired picture images to numeric conversion to find feature quantities. The present invention is characterized by making use of a wavelength characteristic for a document with respect to transmissivity and reflectance of light, extracting feature quantities, in which wavelength characteristic is subjected to numeric conversion, on the basis of picture images of the document picked up by light sources having a plurality of wavelengths, and discriminating authenticity of the document from the feature quantities.

Description

technical field [0001] The present invention relates to a document authenticity identification device for identifying the authenticity of, for example, an ID card, a driver's license, etc., and more particularly relates to a document having a high identification performance for authenticity identification by correctly reading out authenticity degree information A device for authenticity identification and a method for identification of authenticity of certificates. Background technique [0002] In general, such a certificate authenticity identification device is installed, for example, in an automatic contract machine, etc., and optically reads the recorded content of a certificate such as an ID card presented by a user, and performs collation and authentication. [0003] In this case, when the identification of the authenticity of the certificate is carried out, the certificate is photographed under visible light, the captured image data is obtained, and then the authentici...
