The invention discloses a traffic accident information processing method, and relates to the technical field of information encryption. Comprising the steps of identifying sensitive information in a traffic accident file; converting an area where the sensitive information is located into a first grayscale image area; a six-dimensional chaotic sequence generated through iteration is used for converting pixel points in the first gray level image area, and a second gray level image area is obtained; carrying out DNA coding on pixel points in the second grayscale image region to obtain a first DNA coding matrix; performing high-low position separation on the first DNA coding matrix to obtain a plurality of first DNA sub-coding matrixes; encoding the six-dimensional chaotic sequence DNA, and performing DNA logic operation on the six-dimensional chaotic sequence DNA and the first DNA sub-encoding matrix to obtain a plurality of second DNA sub-encoding matrixes; performing high-low position splicing on the second DNA sub-coding matrix to obtain a second DNA coding matrix; and decoding the second DNA coding matrix to obtain a ciphertext image. According to the method disclosed by the invention, sensitive information in traffic accident files in different formats can be encrypted.

    本发明公开一种交通事故信息处理方法,涉及信息加密技术领域。包括识别交通事故文件中的敏感信息;将敏感信息所在区域转换为第一灰度图像区域;迭代生成的六维混沌序列对第一灰度图像区域中的像素点进行变换,得到第二灰度图像区域;对第二灰度图像区域中像素点DNA编码,得到第一DNA编码矩阵;对第一DNA编码矩阵高低位分离,得到多个第一DNA子编码矩阵;将六维混沌序列DNA编码并与第一DNA子编码矩阵进行DNA逻辑运算操作,得到多个第二DNA子编码矩阵;将第二DNA子编码矩阵高低位拼接,得到第二DNA编码矩阵;将第二DNA编码矩阵解码得到与密文图像。本发明公开的方法可对不同格式的交通事故文件中的敏感信息加密。
