Secure Watermarking Algorithm for Enhancing Invisibility and Robustness of Medical Images

In contemporary times, within a society that is highly advanced in terms of technology, all data is gathered and archived in a digital format. In the realm of medicine, diagnostic data is also captured and transmitted in a digital format. The paramount considerations when transmitting information through digital means are security and authenticity. Watermarking is a technological approach that guarantees the credibility and genuineness of clinical images, patient data, and diagnostic data.The present study introduces a secure watermarking algorithm that enhances both invisibility and robustness simultaneously. The transform domain scheme is utilized as a primary step to ascertain the suitable coefficient for embedding data. In order to provide a fair balance between robustness and invisibility, this research provides a secure watermarking method using hybrid transformation. Multiple attacks are also included to show the robustness of the images.
