Application of the RS method to detect steganographic messages in database tables.

摘要

Steganography is the practice of hiding communications. In modern practices, this is usually accomplished by distributing the message within a much larger, unsuspicious set of data. Steganographic methods have been developed for hiding messages in many different types of data. The most widely discussed medium for steganography is digital images. Recently, the RS method has been proposed to estimate the length of steganographic messages in raw format images. In our research, this existing method is applied to a different steganographic domain, that of database tables.
