Working in both domains concurrently addresses both issues of quality and reduced storage size. Experimental results as well as empirical observations have shown that this technique is very competitive with the widely used JPEG image compression standard with the added advantage of being able to recover the original quality without any degradation common in lossy compression techniques. This paradigm has potential for many more applications related to multimedia data hiding. For example, techniques described in this chapter may be used in hiding fingerprint scans inside a person’s own photograph for security checks.
This embedding-extraction loop can be considered as a security key for recovering the hidden data. Without knowing the correct embedding loop, it becomes a guessing game for successfully recovering the hidden information. 25 Data Secrecy To accurately compare our FFT-based data hiding techniques described in this chapter with the most common methods used for data hiding it becomes necessary to assess the data loss issues (fidelity of stego and recovered data) that are inherent in steganography algorithms.
