Abstract: There are some disputes on digital imaging as evidence. This article proposes and establishes an anti-counterfeiting information system for forensic digital imaging based on watermarking techniques. The system， which can ensure the evidence effectiveness of digital images， consists of encrypting and anti-counterfeiting subsystem， information management subsystem and verification subsystem for encrypting information.

Key words: digital imaging, evidence, watermark

摘要： 数码影像作为证据使用存在一定的争议，针对此提出并建立了基于水印技术的司法数码影像防伪信息系统，该系统由加密防伪子系统、信息管理子系统和加密信息验证子系统组成，为确保司法数码影像的证据效力提供了一种技术方案。
