A Hidden Data Transfer System Implementation Within Digital Voice For Wireless Communications

Techniques for information hiding (steganography) have nowadays become increasingly more sophisticated and widespread. Researches on secret information embedding have received considerable attention for a decade due to both its ever increasing potential applications in multimedia data transfer and information security. The main objective of this research work presented is to design and implement a new hidden data transfer mechanism within digital voice for real-time wireless communications using the LSB steganography approach. Furthermore, the application programme developed aims at enabling a high quality conventional wireless real-time voice communication. In this research study, computers with different configurations and a wireless access point are utilized. These computers are equiped with wireless communication tools and software components. The softwares introduced in this paper are developed with Borland Delphi 7.0 programming language. Examples of the application results of the proposed steganography system implementation are also presented, followed by a basic hardware-based performance evaluation.
