COMPRESSED DOMAIN DATA HIDING APPROACH ON ENCRYPTED IMAGES USING AUXILIARY INFORMATION

Creators

Description

 This paper presents secret data concealment and compressing encrypted images on auxiliary information generation for efficient secure transmission under insufficient bandwidth. The process starts by encryption of uncompressed original images and generation of some auxiliary information,which will be used for data compression and image reconstruction. Then,the channel provider compress the encrypted data by a quantization method with optimal parameters that are derived from a part o f auxiliary information and transmit the compressed data,which includes an encrypted sub - image,the quantize d data,the quantization parameters and another part of auxiliary information. In this project discrete cosine transform is used under the quantization method f or encrypted image compression. The secret text mes sage is first converted to bit st reams then it will be concealed into encoded bit s of generated binary map.
