    Compression and data-hiding can reduce transmission cost and secure transmissions, respectively, but hiding information directly in the compression codes is one way to meet the two requirements simultaneously. Because of the low redundancy, few lossless compression methods have been applied in the research. Lempel-Ziv-Welch (LZW) coding is a well-known lossless compression algorithm that is simple...
