This paper briefly reviews the emerging use of and the application of steganographic techniques for exchanging secret messages in a digital medium. In the era of ever-increasing cyberattacks, there is an extreme need for reliable and secure communication. In this respect, cryptography approach has been used to encrypt or encode a textual message with a protective key to prevent unauthorized access. However, encrypted information can conspicuously challenge the hackers and instigate them to crack the code. In contrast, stenographic methods are surreptitiously employed on what appears as a perfectly normal text is actually hiding certain secretive message contents. In a two-part communication structure comprising the message and the message transport, the message is hidden by applying steganographic techniques to be delivered by Simple Object Access Protocol (SOAP). The author's contribution is a proposed algorithm that resolved current algorithm limitations by increasing message size, maintaining the stego file size equivalency to the real file, and minimizing the real message and the stego message differences. This is accomplished by developing encoding and decoding functions in the algorithm. The encoder extracts the equivalent sequence number from a predefined file representing a null value to generate an arbitrary record to be written to an XML file. The decoder read and select the block to extract the equivalent number that equals the null tags, and search in the database to select the equivalent character to the extracted number to be added to the string. Optional SOAP fields which are normally empty or unfilled are also being used with other tags to hide one character, so one block will be equal to one character based on null values. The XML file, embedded with the SOAP tags, which provides competitive performance in benchmark tests, can be used to securely transact information over the Web.
