A blind watermarking using MSB insertion to embed multiple watermarks

This paper presents a blind invisible image watermarking technique to embed multiple watermarks into a single image. The specified technique embeds more than one watermark into the base image by inserting the most significant bit (MSB) of each watermark into the lower order bits of the base image based on the key. It also discusses about the replacement of lower order bits of the base image by MSB of the watermark and MSB insertion into the lower order bits of the base image for watermarking.
