Separable Reversible Data Hiding in Encrypted JPEG Bitstreams

Separable Reversible Data Hiding in Encrypted JPEG Bitstreams -- For a given JPEG bitstream and an encryption key, the content owner generates a ciphertext bitstream after syntax parsing and encryption. In the process, the file size is kept unchanged and the format is compliant to common JPEG decoders. When a remote server receives the encrypted bitstream, the data hider parses the bitstream and hides additional messages in it using an embedding key. After the marked encrypted bitstream is constructed, the file size and format compliance are preserved. In this scheme, the server can extract additional messages from the marked encrypted bitstream using the embedding key. On the recipient side, the additional messages can also be extracted from the received bitstream if the embedding key is available. A recipient with only the encryption key can view an approximate image by a direct decryption. If both the encryption and embedding keys are available, the recipient can losslessly recover the original bitstream after decrypting the marked encrypted JPEG bitstream.
