硅胶仿真指纹模伪造指印检验的研究进展

Research Progress on the Inspection of Fake Fingerprints Forged by Silicone Emulated Mold

随着科技进步和互联网的发展与普及,伪造指印的手段愈加丰富,鉴定实践中也涌现出一批伪造或声称伪造指印的相关案件,给指印鉴定工作带来巨大挑战。针对硅胶仿真指纹模伪造指印,综述了其制作材料、特征变化规律、影响因素和指印特征的表现形式,总结和分析了伪造指印与真实指印所表现的特征差异。汗孔特征、痕迹边缘特征、微气泡特征、边角特征是区别硅胶仿真指纹模指印与真实指印的重要参考特征,为高仿指纹模捺印指印的检验及鉴定提供系统科学的依据。

With the progress of science and technology and the development and popularization of the Internet,a number of related cases of forgery or claiming to be forged fingerprints have emerged in the identification practice,which showed great challenges to the fingerprint identification work.Aiming at forged fingerprints with silicone simulated fingerprint molds,this article reviews the production materials,feature changing rules,influencing factors and the expression of fingerprint features.The differences between the fake fingerprints and the real were summarized and analyzed.The features of sweat hole,trace edge,micro-bubble and edge corner are important references to distinguish the fingerprints of silicone emulated mold from the real,providing systematic and scientific reference for the inspection and identification of high imitation fingerprints.
