Enhancing Secure Data Transfer Through Blockchain, Steganography, and Advanced Cryptographic Algorithms (RC5 and AES)

A scientific study presents secured data transmission systems that unite blockchain technology with both steganographic methods and sophisticated cryptographic algorithms specifically such as RC5 and AES. Blockchain technology creates an unchangeable data storage system through an irreversible transaction log along with complete tracking abilities for information integrity. The purpose behind steganography involves making secrecy-protected information hidden inside normal data to secure transmission privacy. The communication channels attain protection by combining RC5 encryption with AES encryption. MATLAB acts as the platform for system implementation that conducts security protocol evaluations to determine strength levels and processing speed alongside attack resistance capabilities. Multiple protective layers in a security framework enable effective protection of data transmission thereby making it appropriate for healthcare applications along with financial institutions and governmental organizations.
