Design and Analysis of Hybrid Model Using DELPHI Encoding for Visible and Invisible Image Watermarking

the digital data is transferred over the internet which may harm the digital data like tampering of data etc. Therefore, the need of digital data protection has been increased with the advancement in the technology. Watermarking is a technique used to protect the digital data. Digital watermarking is a technique by using which user can get the copyright of its product which prevents the data from tampering. Many techniques are available for video watermarking like Discrete Wavelet Transform, Least Significant Bit Technique etc. (2).The properties of digital watermarking are For copy control, In fingerprinting, For identification of ownership, For Authentication, Monitoring of digital video broadcast, In video tagging etc. (1).
