摘要：Digital imagery is protected from malicious attacks through precise authentication techniques. The authentication method proposed in this paper involves a secret sharing technique with data repair capability for colour images using PNG images. Halftoning is applied to the image channels to enable better visual quality of the recovered image. Scrambling is used along with secret sharing to enhance security. If the image is found tampered on authentication, data repair facility is utilized to retrieve the original colour image
