摘要:

伪造、变造文件检验属于司法取证中文书鉴定部分,传统方法需要依靠文检设备和专业检测人员,具有检测成本高、检测时间长,可能存在有损检验等局限。近年来只利用扫描仪和计算机的数字被动无损取证技术应运而生。文章首先阐述了文件生成过程及其伪造、变造方式,其次对伪造、变造文件的被动无损取证技术进行了总结和分析,从设备取证、纸张取证、文件变造取证三个方面详细阐述了文档来源取证、纸张来源取证和文档真实性鉴别的原理和技术方法。对具体设备和每种变造方式引入的特征进行了详细的介绍,并阐述相应的取证方法,最后给出了数字被动无损取证技术面临的问题和挑战。

Abstract:

The examination of forged and altered document is an important part in judicial expertise. The traditional examination methods need professional testers and devices, the disadvantages include high cost, long testing time, damage on the documents, etc. In recent years, the digital passive lossless forensics on forged and altered document has been developed which only uses scanner and computer. In this paper, we first introduce the life-cycle of document and its forging and altering methods. Then, we summarize the passive lossless forensics on forged and altered document, and describe the technologies on device identification, copy paper identification and authenticity detection, respectively. We give a detailed description on the characteristics introduced by devices and altering methods, and their forensics methods. Finally, we describe the questions and challenges on digital passive lossless forensics on documents.

Key words: forged and altered document examination, digital passive lossless forensics, device identification, authenticity detection, copy paper identification
