Robust Reversible Watermarking Application via User Interface

In the digital era, particularly in medical applications, ensuring the originality and security of digital images has become a critical concern due to the ease with which digital content can be duplicated and altered without authorization. The main objective of this study is to produce a desktop-based application named Wmarks, which ensures the integrity and authenticity of medical images while providing copyright protection. Wmarks employs the adaptive spread spectrum method to implement a robust, reversible image watermarking technique, prioritizing both security and ease of use. The focus of Wmarks is to ensure the security of digital images, particularly in medical contexts, while offering a reliable user-friendly interface that simplifies the process of embedding and retrieving watermarks without compromising image quality. Functionality testing was conducted on two devices, a laptop and a PC, to evaluate performance. The results indicate excellent latency responsiveness, with an average response time difference of 58.079 ms between the devices. Black box testing further confirmed that Wmarks performs efficiently across all features. In terms of resource consumption, the application demonstrated optimal performance, with CPU usage ranging from 0–4% during idle conditions. Usability testing was conducted with 30 respondents using the System Usability Scale (SUS), resulting in a score of 80.35, reflecting positive feedback and high user satisfaction. These results indicate that Wmarks effectively secures sensitive digital content, particularly in medical fields, while being easy to use and implement in professional settings.
