Current Status and Future Directionsl amount of data; and once data are hidden in an image or audio file, any lossy compression destroys the embedded data. It seems that such an image should be compressed with lossless compression only, but this chapter shows how secret data can be hidden even in a lossily compressed image.

The computer may be programmed to check each plaintext as it is being generated and reject it if it looks random or if it consists mostly of phrases that are not in the dictionary. Such an automatic check, however, would still leave too many plaintexts for a human to examine.
