摘　　要：莫尔条纹信息隐藏技术避开复杂的计算进行解密,却存在隐蔽性不足的缺点。通过计算贝塞尔函数、灰度值和谐波振幅等得到时间平均莫尔条纹。时间平均莫尔条纹信息隐藏技术的载体图像和秘密信息由一组时间平均莫尔条纹组成,初始相位匹配和随机置乱算法将秘密信息嵌入到载体文件,保证了肉眼不能区分秘密信息与背景图片之间的差异,秘密图像只有按照预先计算的振幅振动才能显示原始的秘密信息。验证了秘密信息的安全性。Moire fringe information hiding technology avoids complicated calculation and can be decrypted,but it has shortcomings of concealment.The time-averaged Moire fringes are obtained by calculating the Bessel function,gray value and harmonic amplitude.The carrier image and secret information based on time-averaged Moire fringes are composed of a group of time-averaged Moire fringes.The secret information is embedded into the carrier file by initial phase matching and random scrambling algorithm,which ensures that the naked eye cannot distinguish the difference between secret information and background image.The secret image can be displayed only according to the pre-calculated amplitude vibration.The initial secret information enhances the security of secret information.
