摘　　要：分析手机特定软件的美化操作对JPEG图像原始性的影响。首先选用不同型号手机拍摄的JPEG图像,其次利用手机上各类不同的编辑软件对JPEG图像进行美化,最后利用WinHex、UltraEdit、Opanda PowerExif 1.2软件提取JPEG图像的格式图像数据、Exif信息并计算其MD5值,对操作前后JPEG图像的格式图像数据、Exif信息、MD5值进行比对。对android手机而言,美化后图像的十六进制编码、Exif信息、MD5值均发生了改变;对苹果手机而言,美化后图像的十六进制编码、MD5值发生了改变,但Exif信息几乎保持不变。手机特定软件对JPEG图像进行编辑后,对图像的原始性有较大的影响。The effect of beautification operation on the originality of JPEG image is analyzed.Methods Firstly,the JPEG images of different types of mobile phones are selected,then the JPEG images are beautified by various kinds of editing software.Finally,the format image data,Exif information and MD5 values of JPEG images are extracted by WinHex,UltraEdit and Opanda Power Exif1.2 software.For android phones,the hex encoding,Exif information,and MD5 values of the beautified image have all changed;for apple phones,the hex encoding,MD5 values of the beautified image have changed,but the Exif information has almost remained the same.After the specific software of mobile phone edits the JPEG image,it has a great influence on the originality of the image.
