Paper Title:
Multiple Watermarks Embedding Simultaneously to Identify Image Status Based on Fractional Fourier Transform
  Abstract

A new method of multiple watermarks embedding simultaneously to identify image status based on once and twice discrete fractional Fourier transform (DFRT) is presented. Random series watermark, chirp watermark and annotation watermark are embedded simultaneously in fractional Fourier transform domain to identify digital tamper detection, scanning detection, duplicate detection. According to the extracting situation of three kinds of watermarks from an image and the twice DFRT amplitude spectrum, we can know whether the image is tampered, scanned or duplicated. It provides a convenient way to identify the status of the image and will be an all-sided and comprehensive anti-counterfeiting technology.
