摘要
为解决水印密钥保密传递和唯一性等问题,将生物识别技术与数字水印相结合,从应用角度分析了现有的数字水印协议和模型,引入生物特征识别技术,给出了一种安全的数字水印协议;实现了一种基于指纹识别的生物特征水印实施方案,解决了一般情况下生物特征数据和数据量较大、难于将其表达成能适应水印嵌入和提取的关键问题。实验证明,该方案是可行和有效的。
To deal with watermark key secure transfer and uniqueness, the feasibility of combining biometric identification technology and digital watermark are studied, the existing watermarking protocol and model, the biometric identification technology in the protocol is introduced, and a secure digital watermarking protocol is proposed. Scheme of biometrics watermark based on fingerprint identification has been implemented to solve key problems for data volume of biometrics which is too large to embed and extract watermarking in general case. The experiment showed that the scheme is effective and feasible.
