Chaotic Reversible Watermarking Method Based on IWT with Tamper Detection for Transferring Electronic Health Record

Health IoT deals with sensitive medical information of patients, therefore security concerns need to be addressed. Confidentiality Electronic Record (EHR) and privacy are two important requirements for based healthcare systems. Recently, watermarking algorithms as an efficient response these is in the spotlight. Further, smart city-based applications have react real-time situations, computation a demand them. In this paper, secure, lightweight, reversible, high capacity algorithm tamper detection capability proposed The scheme has applied Integer Wavelet Transform (IWT) chaotic map efficiency increasing security. EHR encrypted then embedded into Least Significant Bits (LSB) wavelet coefficients images. method been extensively tested various color grayscale commonly used general Investigations on experimental results criterions such Peak Signal Noise Ratio (PSNR) Bit Error (BER) above 45.41 dB 0.04, respectively, payload 432,538 bits indicate that method, besides providing security, being capability, embedding capacity, imperceptibility adequate resistance against different types attacks.
