As digital human image information becomes more valuable and costly to create, the importance of copyright protection in this field has grown significantly. This is particularly true given the diverse applications of such images, ranging from medical diagnostics to artistic endeavors. Historically, copyright protection for digital images has utilized invisible watermarking techniques. These methods embed information within the image to assert ownership and prevent unauthorized use. However, one major drawback of this approach is that the deformation caused by various image processing techniques can compromise the integrity of these invisible watermarks. This limitation poses challenges, especially in sensitive applications like medical diagnosis, where accuracy and clarity of the images are paramount. In this paper, we conduct a thorough examination of the unique characteristics of still images, focusing specifically on digital human image information. By analyzing the limitations of existing copyright protection methods, we aim to propose a more effective strategy that takes into account the intended purpose of the images. This new approach seeks to provide robust copyright protection while ensuring that the images remain suitable for their specific applications, thus balancing the need for ownership rights with functional usability.
