A hybrid framework for secure data transfer for enhancing the Blockchain Security

In order to improve the secure transfer of sensitive data, this paper investigates the integration of blockchain, steganography, and optimization algorithms. By obscuring data within files, boosting anonymity in blockchain transactions, and enabling watermarking for evidence of ownership, steganography enhances blockchain. By concealing access credentials, it protects document exchange and guarantees data integrity for IoT. Steganography and blockchain work together to improve data security and privacy. A strong solution is put forth by combining these technologies to guarantee the integrity and security of information across a range of sectors. Using steganography and optimization, this method efficiently hides data while also utilizing the security and transparency of blockchain technology. Together, these techniques provide a promising way to handle and send private information securely, especially when it comes to the medical industry. It strengthens the overall security of sensitive medical data transfer by utilizing optimization-based embedding within a blockchain architecture to assure data safety, verifiability, and patient confidentiality. Also parametric assessment of the framework utilized in the current standard techniques is also the part of this study. The proposed method produced a correlation coefficient and PSNR for the Salt and Pepper noise that were, respectively, 0.89 and 52.0.
