Image Analysis

Image analysis has been a hot topic in digital forensics for a few years. Recently it goes out from the field to general public in HK after a sex sandal of a Hong Kong pop star. Professionals came out and tried to prove or disprove whether the photos are frauds.

So what's is image analysis? How are images analyzed? I am not an expert in this field, so I'd better leave these questions to those really professional. I've recent read a blog whose author is a speaker at the BlackHat conference, I guess you'd probably gain something from it like what I did.

  1. I think you may want to check Prof. Hany Farid's research.

    Also, PISA do have a mini research on using JPEGsnoop, ErrorLevel Analysis and ExifTool.

    I have also tried the jpegquality to verify the Q-table of JPEG images.

    However, none of them, except Prof. Hany provides sure win proof of an evidence of tampering of an image.

    ISFS also held a workshop for its members previous
