硅胶高仿指模的检验

在实际工作中,大量的高仿指纹涌现,给指纹鉴定工作带来巨大挑战。为解决案件中高仿指纹的鉴定需求,作者利用真实指纹和文件上的指印,以硅胶和感光树脂板为原材料制作高仿指模,通过其制作原理、形成的机制、变化因素、规律及表现形式,总结和分析高仿指模与真实指纹的特征差异,为高仿指纹鉴定和检验提供科学依据。

Testing of High-imitation Fingerprint from Silicone Gel

A large number of high-imitation fi ngerprints increasingly emerged in the actual life,having brought great challenges to the fingerprint identification.In order to meet the need for identification of high-imitation fingerprints from cases,the high-imitation fi ngerprints were here made with both silicone gel and photosensitive resin plate to represent their copying versions of genuine and/or document-carrying fi ngerprints.Based on the high-imitation fi ngerprint involving to its production principle,formation mechanism,infl uential factors,regular patterns and various exhibits,both summarization and analysis were thereby carried out into the difference between the high-imitation and genuine fi ngerprints,with purpose to provide scientifi c basis for high-imitation fi ngerprint identifi cation and examination.
