Image Authentication

Image authentication is the process of verifying that a digital image is genuine and has not been altered or tampered with. It ensures the integrity and authenticity of the image by checking for signs of manipulation or forgery. This is achieved through techniques like digital signatures, watermarking, or analyzing metadata and visual features. Essentially, it helps confirm that the image truly represents what it claims to, which is important in fields like journalism, forensic analysis, and legal documentation.
