Visual Cryptography is a technology that is used to mask the secret image into transparencies and these transparencies are distributed to the intended recipients. A novel video watermarking scheme based on visual cryptography and scene change detection in discrete wavelet transform domain is proposed. In this we provide the image based authentication that can do login. Password image is generated and it will be downloaded from the email which is stored at the time of registration. Every time the image will be unique. In this system the OTP based authentication is also used. Main objective of this system is to provide security for information using cryptography with video watermarking.
