Towards Versatility: Lossless Data Hiding in JPEG Bitstream via Table-irrelevant Code Mapping

29 Jun 2020 Zhaoxia Yin Yang Du Yuan Ji

Most existing lossless data hiding (LDH) methods for JPEG bitstream embed data by constructing the code mapping between used codes and unused codes. Previous studies only apply to the JPEG bitstream encoded with the standard Huffman table, in which unused codes usually exist hence the construction of code mapping can be guaranteed... (read more)
