Abstract
Many digital signals possess statistical properties that can be exploited to increase the amount of usable information either stored with them in a fixed file size or transmitted with them over a fixed capacity channel. In this paper, we develop a new technique for embedding digital information into such signals. Using the method of types as a tool to analyze the statistical nature of digital signals, we implement a novel scheme which is capable of embedding significantly greater amounts of information than has been possible with traditional steganographic approaches. We are able to achieve these increased rates by not requiring the data to be either hidden or decoded error free. As an example, in wideband speech processing trials using ITU G.722 at 48, 56, and 64 kbps, we are able to embed up to 800 bits/second of additional information with practically no impact on the decoded speech signal. This additional bandwidth can be used for various low data rate applications such as control channel information, text transfer, or security and watermarking. 1.
