Telemedicine is one of the most eminent terms used in the modern e-healthcare system. Digital medical image reports, along with electronic patient records, play a central role in diagnosis from distance. These reports need to be transmitted over an open communication channel with immense security and reliability, so that appropriate diagnosis can be performed. Moreover, the privacy of the patient is required to be preserved. Digital watermarking is one of the most conventional and suitable practices to serve all of these purposes. New challenges appear in the domain of watermarking with the advancement of digital signal processing; consequently, researchers are endowing more efforts to overcome these challenges. In this paper, a survey on medical image watermarking has been done, and the performance of a few state-of-the-art medical image watermarking techniques is compared. This work makes the researchers and the developers familiar with the recent trends, challenges, and scopes in this domain to facilitate them in finding out adequate research directions.

This paper proposes a digital image watermarking strategy using histogram equalization and visual Saliency followed by LSB (Least Significant Bit) replacement for better imperceptibility with hiding capacity. With this technique, a saliency map determines lesser-observable parts of the original image and gradually implants with increasing amounts of information based on histogram equalization information. The output from saliency is the perceptible areas within an image, which is the most notable position from the perspective of vision; as a result, any changes made other than those areas will be less noticeable to viewers. Implementing the histogram method helps identify the areas where we can hide our secret information within that image. Using the LSB replacement technique, we adaptively insert our confidential data into the original image. Here, we use the saliency map to find out the non-salient region or less perceptible region to improve the imperceptibility, and the histogram equalization technique is used to maximize the hiding capacity within those less perceptible regions. So that we can improve the imperceptibility as well as the hiding capacity.

Performance evaluation for image quality assessment plays a very vital role in digital image watermarking. The main objective of this paper is to study the process of statistical analysis of image quality metrics for performance evaluation testing in digital image watermarking. This review gives the basic idea of statistical method ANOVA, which will help the researchers to assess the quality of their methods not only related to image watermarking but also to different fields of research of their own interests. The comprehensive study on some existing methods is also presented in this paper to show the effectiveness as well as the limitations of the performance evaluation metrics in the domain of digital image watermarking.

Electronic health records (EHR) contain patients' medical as well as personal details. With the increased use of digital media, these data are stored and transferred through the electronic media all over the world. This makes it vulnerable to unauthorized people. Digital image watermarking can be a useful process of protecting these data from attacker but causes severe and unrecoverable damage to cover media. In the case of highly sensitive images like medical images, this might creates a problem during further diagnosis. In this chapter, a reversible data hiding algorithm is proposed which also is capable of holding a large chunk of data without affecting the cover media. The main cover image is first reconstructed and hidden behind a bigger media and then the extra pixels are used to hide encrypted forms of EHR data along with an authentication signature. As EHR data and the digital signature is passed through various encryption stages while encoding, it is made more secure. The algorithm is developed on the spatial domain adding some cautious measures which made it fragile as well.

The recent developments of enormous computer networks have invoked insecurities related to copyright theft of digital media. To be precise, the virtual sharing of medical images over networks with a novel desire of improved medical diagnosis has led to the tampering of sensitive patient identity information. In this chapter, the authors have exemplified the need of watermarking with fragile medical image watermarking using saliency and phase congruency. Initially, the saliency and phase congruency methodologies are applied on the original medical image to highlight the object features. Based on the feature map, a mask is generated which segregates the area of interest from the portions containing visual medical information. An encrypted text, containing identity of the patient, is embedded into the area of interest of the image. The results of imperceptibility and fragility criteria are satisfactory towards the implementation of a fragile watermark as the extracted watermark is found to be corrupted upon unfaithful image processing modifications.

The aim of this work is to develop FPGA architecture of such an image watermarking scheme that can overcome the tradeoffs among the major three qualities – imperceptibility, robustness, and payload. This proposed scheme, developed in spatial domain, can be performed to embed gray-scale watermark image into any single color-plane of a cover object. Embedding has been performed in such a manner that the watermark pixels of any particular shade can be inserted into cover image pixels having the same or contiguous shades. This way, the visual transparency of the embedded information has been improved. Efficiency of this proposed scheme has been assessed through some image quality metrics, and compared to the same of some new age image watermarking techniques. The comprehensive analysis asserts that this watermarking system is able to meet its goal successfully.

Blockchain is a distributed ledger technology, frequently used in the creation of new digital currencies. The rapid development of blockchain technology has resulted in numerous new successes in industry and academia. This architecture is now widely used in e-finance as a widely accepted electronic money. It possesses critical characteristics such as immutability, decentralisation, and transparency, which may aid in the resolution of major healthcare challenges. Highlighted issues are like, incomplete treatment records, restricted access to patients’ own health records and so on. A blockchain architecture stores multiple copies of a single piece of data in various locations and on various devices. Hence, even if one copy of data is damaged or tampered, other copies remain immutable. The link between the blocks prevents any of the information from being changed or a new block from being placed between two existing blocks. A healthcare record management system based on blockchain technology is proposed in this paper. The proposed model is a multilayer architecture with different components representing various entities related to the healthcare system. Patients, doctors, clinics or hospitals, medical records, and so on are examples of entities. Effective sharing of medical data, ensuring Authentication and Authorization, is one of the most important aspects of this research.

Many new successes in industry and academia have resulted from the rapid development of blockchain technology. This architecture is currently widely employed in e-finance as a generally acknowledged electronic money. It has crucial qualities like immutability, decentralization, and transparency that could help with critical healthcare challenges also. These issues may include incomplete records at the point of care, restricted access to patients’ own health information, etc. Multiple copies of a single data are stored in various locations and on several devices of a blockchain architecture. In spite of lose or damage of one copy of data, multiple copies remain safe and secure. The connection between the blocks prevents any of the information from being modified or a block from being put between two existing blocks. In this paper, a healthcare data management system based on blockchain technology has been proposed. The proposed model is a multilayer architecture where different entities related to healthcare system will be different components. The entities are patients, doctors, clinic or hospitals, medical records etc. Effective medical data sharing is one of the important aspect of this research work.
