A Bit Modification Technique for Watermarking Images and Streaming Video
This paper demonstrates a bit modification technique for embedding watermarks of known strings of data applied to a color image. For watermarking of images and video frames, low payload information can be embedded indiscernibly and with quick and easy manipulation of pixel bits. Robustness of the hidden watermark with added noise is shown as a tradeoff with visibility, as is the case with the size of the watermark. By retrieving the hidden watermark in an oblivious manner, the technique can be used in copyright and authentication applications. The simplicity of embedding and blind recovery with low level noise-resistance render the proposed technique suitable for imperceptible watermarking of still images and streaming video over public networks.
