利用信息技术增强数码影像证据力

摘要

由于数码影像相对于胶片照片容易造假，所以不容易被采信。针对这一问题本文阐述了在数码影像里添加GPS信息的原理和过程，提出在数码影像这类电子证据里嵌入GPS信息，再结合数字水印、MD5值等信息安全技术来增强其证据力。%Digital image is more likely to be forged than film, so it is not easy to be believed. To solve this problem,the paper analyzes how to add GPS information into digital image. As some electronic evidence is digital images, so we can embed GPS information in digital images ,combining with digital watermarking ,MD5 values, or other security technology to enhance the evidence force of the electronic evidence.
