A hand bone identification system

Abstract

The invention relates to the technical field of information security, and in particular relates to a hand bone identification system. The hand bone identification system comprises a collection module, a preprocessing module, a characteristic extraction module, a hand bone database and a characteristic identification module, wherein the collection module collects and transmits an X-ray image of hand bones to the preprocessing module; the preprocessing module carries out morphological calculation, grey level transformation, histogram equalization, image smoothing and image normalization on the image of the hand bones, and transmits the processed image to the characteristic extraction module; the characteristic extraction module extracts the hand bone contour from the image of the hand bones, and calculates the characteristic value of the hand bone contour according to the image of the hand bone contour; and the characteristic identification module carries out clustering and classification on pre-collected hand bone images and characteristic values thereof in the hand bone database, and identifies the hand bone image to be identified according to the characteristic value of the hand bone contour provided by the characteristic extraction module. The hand bone identification system has the advantages that the identification data is not easy to disguise so that the identification accuracy is high.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an identification system for hand bones. Background technique [0002] In today's society with highly developed information technology, how to accurately identify a person's identity and protect information security is a key social problem that must be solved in today's information age, which requires an identification system. Identification systems have been applied to various industries and are increasingly used. According to research reports, the easier it is to obtain biometrics, the greater the possibility of being maliciously attacked by humans. So far, fingerprints, faces, voices, palm prints, gait and auricle recognition methods all have weaknesses, and it is difficult to identify artificial modifications and camouflage. As a new identification method, hand bone recognition aims to use hand bone X-rays as the basis for identification, making it difficult fo...

Problems solved by technology

[0003] However, at present, the use of palm bone X-ray films is mainly used to study the assessment of bone age, and there is no research on the application of identity recognition.
