| Resumen |
Today, with the advance of science and technology, there is a way to obtain and visualize medical studies digitally, such as Magnetic Resonance Images (MRI). Due to the ease with which images can be manipulated in PNG format, an important disadvantage arises. Anyone who masters an editing program can corrupt the image, causing a loss of quality or, in the worst case, modifying the information contained in each patient. In this work, we have developed a standalone application capable of encrypting and hiding patient information in MRI images. It is made by proposing the use of digital watermarks as an effective solution for protecting patient data through hidden watermarks, using the least significant bit replacement technique to hide such information, in addition to adding another security filter with the help of encryption, making these sensitive data completely unreadable if the watermark is extracted, thus implementing another level of security, so that only authorized physicians can insert and extract the information, seeking to mitigate forgery and misuse in digital medical studies. The quality of the watermarked MRI images was measured using the PSNR metric, while the image quality was measured using the SSIM metric. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026. |
