DIGITAL WATERMARKING: A SURVEY
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2015, Vol 6, Issue 9
Abstract
This is the era of digital information as digital image plays a vital role in every field of human lives. A digital image is both informative and flexible since it is easy to edit and redistribute. The vulnerability of digital image increases along with its use. So the security and confidentiality need to be maintained. Digital watermarking is the technique that provides security to the digital image where a low energy signal (watermark) is embedded in the original signal (host) to make the host imperceptible. The host signal may be any form of digital multimedia data like image, audio or video. When the watermarking technique is performed on the host signal, it becomes free from unauthorised access and can only be detected or extracted as required by the authorised receiver.
