Abstract: Due to large number of transmission of digital image over non-secure internet, image authentication techniques have recently gained great importance. Digital watermarking is utilized for copy write protection and ownership detection. However as techniques are get improved more focus is given to authentication. Because of authentication digital image become secure and protected to transfer the information over internet. To protect the authenticity of multimedia images different technique has been proposed. These approaches include conventional cryptography, fragile& semi fragile watermarking and digital signature that are based on image content. This paper presents the overview of techniques used for authentication. The different techniques are summarized and compare with each other by considering experimental results.
