Abstract A reliable medical image management must ensure proper safeguarding of the electronic health records. Safeguarding the medical information of the patients is a major concern in all hospitals. Digital watermarking is a technique popularly used to protect the confidentiality of medical information and maintaining them which enhances patient health awareness. In this paper, we propose a blend of discrete wavelet transform (DWT) and singular value decomposition (SVD) for watermarking the EHR. The EHR is further encrypted using key-based encryption method for access control. The SVD is applied to the approximate and vertical coefficients of the wavelet transform. The technique improves EHR protection and facilitates in accounting for performance parameters like peak signal-to-noise ratio (PSNR) and mean square error (MSE). Additionally, the properties of gray-level co-occurrence matrix like normalized cross-correlation (NC), wavelet energies, and homogeneity between the pixel pairs of host and the encrypted watermarked EHR are exploited.

1 Introduction This era has led to major technological innovation, Internet being the forehand in it. The advent of internet being deployed for many applications has made tremendous progress in wide spectrum of fields like medicine, health records, diagnosis, etc. Fast and secure access to patient’s records helps to save lives with timely treatment in emergency situations. Therefore, anywhere anytime accessible online health care or medical systems play a vital role in daily life. It taps down this advantage of the need B.K. Sujatha Mamtha Mohan (&) S.B.

for wide scale protected accessibility of health records to provide a safe and efficient way of sharing and accessing the patient’s records. The EHRs (electronic health records) is a methodical way of maintaining, securing, and protecting health information of patients. It facilitates high quality patient treatment and awareness. EHR contains case study, diagnosis, blood reports, medication, reports about various other conditions, and other necessary undergoing treatment. Moving to electronic health records is important to the modernization and revamping of our healthcare system, but it poses great challenges in the areas of security, safety, and privacy of patients records. Computerized medical records are prone to potential abuses and threats. In the last few years, thousands of human fraternity have faced co
