Framework for Enhanced Digital Image Transmission Security: Integrating Hu Moments, Digital Watermarking, and Cryptographic Hashing for Integrity Verification

Image stability is very important in a time when digital image communication is essential to many fields. Modern online dangers are often too complicated for old security methods to keep up with. To solve these problems, this study presents a new system that combines Hu moments, digital watermarking, and cryptography hashing. Hu moments create a unique graphic stamp that can be used to check the image after it has been received. Digital watermarking increases the integrity of information because it involves a code that cannot be seen but can be detected to make changes impossible. The digital fingerprint is created with such hashing algorithms as SHA-2s and other cryptographic hash functions before the message transmission. This fingerprint can be utilized to verify the integrity of a message when it arrives at its destination. Our combined method provides a comprehensive defense against image hacking, guaranteeing the accuracy of images sent over networks that might not be fully safe, the structure is made to be invisible, protecting image quality while offering strong security against changes. We will explain how this whole system was put together, how it will be used, and how it should be evaluated. We also discuss how it could be used in many situations where the quality of digital images is very important.
