1. the digital watermarking encryption system based on profile wavelet transformation and oval encryption system cryptographic algorithm is characterized in that, at first, the author defines individual function watermark, preserves watermark file;

  • The second, the author chooses the point that watermark embeds, and selects individual private key, produces PKI, utilizes oval encryption system cryptographic algorithm public key encryption watermark to embed point, forms the pass point sequence, preserves the pass point sequence;

    The 3rd, the author is read in image to be encrypted and individual watermark, and individual watermark is embedded in the image to be encrypted, and the profile wavelet transformation is adopted in the conversion of image and inverse transformation, preserves the image after encrypting, and is formed with the works of author'"'"'s watermark.
