Theoretical Analysis Of Forged Fingerprint Identification Methods

With the rapid development of biometrics technology,using the uniqueness of biometrics for personal identification has gradually entered the stage of maturation.Fingerprint identification technology is one of the most mature and widely used technologies.It has been a hundred years since the application of the relative stability and specificity of fingerprints has been applied to identify the personal in various fields.Before the rise of biometrics identification technologies such as DNA,fingerprints were once considered the “ head of evidence ” in the process of inspection,identification and litigation..Based on the image trace attribute of fingerprints,combined with high IQ and high-tech crime models,the morphological characteristics of fingerprints have become the basic conditions of forged fingerprint.The crime of replicating and forgery of the real fingerprints to obtain benefits have been presented to people gradually,especially the color printing and copying methods and the forgery of the corpse fingers.With the appearance of fingerprint film making materials and production methods,in particular,3D printing technology has broken through the difficulties of fingerprint film printing.The number of criminal implicit cases which uses forged fingerprint to steal important information,obtain illegal profits,and escape from judicial punishment is increasing.This new criminal form has brought great difficulties to the inspection and appraisal work.At the same time,the accurate recognition capability of the fingerprint identification system is also facing challenges.How to improve the fingerprint identification system’s accurate identification of forged fingerprint is also a new challenge in the field of fingerprint recognition.Therefore,it is very important to solve the identification method in facing the challenges brought by forged fingerprint.However,there are few studies on systematization,integrity and comprehensiveness of forged fingerprint.So,it is necessary and urgent to carry out a systematically summarize and research on the methods for fabrication and identification of the forged fingerprint.Therefore,collating and analyzing the related issues such as the influence of forged fingerprint on the security of fingerprint identification systems,methods for making forged fingerprint,and identification methods.This is also the intention and innovation of this subject,trying to improve it in the theoretical level so that it can play a role in the industry’s future practice.Finally,it is hoped that through the arrangement of forged fingerprint production methods and identification methods.Making the judicial practice department pay great attention to the issue of forged fingerprint,and it will be able to properly cope with this type of illegal and criminal activities under theconcerted efforts of everyone.This topic mainly focuses on sorting out and analyzing the methods of making forged fingerprint.The full text consists of six parts.The first part is the introduction part,mainly from the background of the appearance of forged fingerprint.The second part is the summary of forged fingerprint,mainly including the research situation of forged fingerprint at home and abroad,the theoretical basis for forged of fingerprint and the concept of determining forged fingerprint,etc.The third part is to analyze the influence of forged fingerprint on the fingerprint identification system,including the working mechanism of the fingerprint identification system,and the guarantee of the reliability of the identification of forgery fingerprint.The fourth part is the summary of the traditional methods and identification of forged fingerprint.Including the color printing and copying method to forge fingerprints,the transfer of real fingerprints to other forged fingerprint,use of body fingerprints to forge fingerprints,photo-making method forging fingerprints,and transfer printing methods to forge fingerprints;and the identification method.The fifth part is the production method and identification of using fingerprint film to forge fingerprint,including the use of silica gel fingerprints film to forge fingerprint,the use of laser engraving fingerprints film to forge fingerprints and the use of biological 3D printing fingerprints film to forge fingerprints and other content.The last part of the article is the conclusion which summarizes the whole text,and points out the deficiencies and expectation of this topic.
