中文摘要	提出了一个新的基于小波系数和混沌序列的图像认证方法.首先对图像进行二级小波变换,利用混沌序列对二级高频系数进行编码,然后对编码后的系数进行小波逆变换得到处理后的图像.; A novel image authentication algorithm was proposed,which was based on wavelet coefficients and chaotic sequences.A 2-leve wavelet transform was performed on the image,and its 2-leve high-pass coefficients were coded with chaotic sequences.Then,an inverse transform of the coded coefficients would produce the revised image which could ensure the integrality of the image.The experiment proves that this authentication method is very effective and useful.; 【作者单位】集美大学计算机工程学院；集美大学计算机工程学院福建厦门361021；福建厦门361021；【作者英文名】Li Chuan-mu,HONG Lian-xi(School of Computer Engineering,Jimei University,Xiamen 361021,China)
