Scalable Image Encryption Based Lossless Image Compression

摘要

Present days processing of the image compression is the main protective representation with considerable data process on each image progression. Traditionally more number of techniques were introduced for during efficient progression in image compression on the data set representation process of application development. A content owner encrypts the original uncompressed image using an encryption key. Then, a data hider may compress the least significant bits of the encrypted image using a data hiding key to create a sparse space to accommodate some additional data. With an encrypted image containing additional data, if a receiver has the data hiding key, receiver can extract the additional data though receiver does not know the image content. If the receiver has the encryption key, can decrypt the received data to obtain an image similar to the original one. If the receiver has both the data hiding key and the encryption key, can extract the additional data and recover the original content.
