基于人像图像的随机序列发生器

摘要

通过利用人像面部表情特征的差异性和获取(拍摄)过程中随机性,提出了一种新的随机序列生成方法；通过将图像获取过程中的随机噪声与人体生物特征相结合的方式产生随机源.仿真测试表明,该方法产生的随机序列不具有线性相关性和非线性相关性,具有优良的均匀度和FIPS PUB 140-2及NIST 800-22测试通过率,能够满足信息安全的需要,并且方法简单,易于实现.%According to the different of facial feature of Portrait images and the random of shoot process of portrait images, a new random sequence generation method was proposed, which the random noise in portait image acquisition process was combined with human biological characteristics to generate the random source. The simulation tests show that the sequence generated by this method is neither linear dependent nor nonlinear dependent, is of excellent uniformity and high test pass rates of FIPS PUB 140-2 and NIST 800-22 to meet the needs of information securitu, and the melhod is simple and easy to realize.
