Resource optimized TTSH-URA for multimedia stream authentication in swallowable-capsule-based wireless body sensor...

Area of Science:

• Biomedical Engineering
• Wireless Communication
• Information Security

Background:

• Swallowable capsule endoscopy is crucial for remote gastrointestinal (GI) diagnostics, reducing hospitalization burdens.
• Wireless Body Sensor Networks (WBSN) enable remote GI examinations but face challenges in secure, efficient multimedia transmission.
• Ensuring video quality and energy efficiency in GI-WBSNs is critical for reliable remote diagnostics.

Purpose of the Study:

• To develop a joint resource allocation and stream authentication scheme for GI-WBSNs.
• To optimize video quality, security, and energy efficiency in swallowable capsule-based remote examinations.
• To address the critical challenges of secure multimedia transmission in GI-WBSNs.

Main Methods:

• Proposed a unique signature-hash (S-H) diversity approach for robust video authentication and reduced overhead.
• Developed a two-tier signature-hash (TTSH) stream authentication scheme to enhance video quality by minimizing authentication dependence.
• Integrated TTSH with an S-H oriented unequal resource allocation (URA) scheme for improved energy-distortion-authentication performance.

Main Results:

• The proposed TTSH stream authentication scheme effectively reduces authentication overhead while maintaining video integrity.
• The combined TTSH with URA scheme significantly improves the energy efficiency of wireless video delivery in GI-WBSNs.
• Simulation results demonstrate considerable gains in both authenticated video quality and energy efficiency.

Conclusions:

• The novel TTSH with URA scheme offers a robust solution for secure and efficient video transmission in GI-WBSNs.
• This technology enhances the reliability and performance of remote gastrointestinal examinations using swallowable capsules.
• The findings contribute to advancing remote diagnostic techniques by optimizing multimedia transmission in WBSNs.
