Medical images can be intentionally or unintentionally manipulated both within the secure
medical system environment and outside, as images are viewed, extracted and transmitted …

Watermarking has been considered to be a potent and persuasive gizmo for its application
in healthcare setups that work online, especially in the current COVID-19 scenario. The …

With the remarkable development of internet technologies, the popularity of smart healthcare
has regularly come to the fore. Smart healthcare uses advanced technologies to transform …

In this paper, we present a robust and secure watermarking approach using transform
domain techniques for tele-health applications. The patient report/identity is embedding into …

Robustness, imperceptibility and embedding capacity are the preliminary requirements of
any watermarking technique. However, research concluded that these requirements are …

This paper presents a chaotic encryption-based blind digital image watermarking technique
applicable to both grayscale and color images. Discrete cosine transform (DCT) is used …

Maintaining secured patient credentials in telemedicine is becoming a critical task. Image
watermarking is one of the solutions to this problem. It is extensively used to protect and …

With the increasingly widespread use of medical images in medical institutions and
networks, the copyright protection of medical images has become increasingly urgent. Since …

In this paper, a blind image watermarking scheme based on discrete wavelet transform
(DWT) and singular value decomposition (SVD) is proposed. In this scheme, DWT is applied …

A new high capacity and reversible data hiding scheme for e-healthcare applications has
been presented in this paper. Pixel to Block (PTB) conversion technique has been used as …
