| Abstract [eng] |
VOIP is the most widely used IP network service; the communication of video and voice between remote departments or to provide support anywhere on Earth is an irreplaceable tool for international organizations. Confidential information is a highly valued commodity; exposed information provides competitors knowledge to create less expensive services or potential vulnerabilities to ruin a organization. This has resulted in an emerging demand for secure exchange of information without changing habits and without installing complicated expensive solutions. Stegnographic techniques can achieve this objective of hiding sensitive information in a VOIP network. With the aim of improving the standard LSB stegnograpic algorithm resistant to changes of VOIP network data, a method must be developed to meet the minimum information obscurification requirements: be safe, difficult to penetrate, and not introduce extraneous noise that interferes with VOIP services. The decision analysis is a comparison of these three assessment characteristics across competing similar methods. The final result is an algorithm implementation for VOIP network. Based on experiments, the algorithm is evaluated by its suitability for secret data transfer and its resistance for stego- analysis attacks. |
