MATLAB Algorithms for Rapid Detection and Embedding of Palindrome and Emordnilap Electronic Watermarks in Simulated Chemical and Biological Image Data
Abstract
Data can easily be hidden in images by using the least significant bits. The most significant bits may be a watermark or annotation which covers the important data. Routine written in Matlab can be used to generate hidden data in the photographic annotation image. Electronic watermarks are used everyday to protect copyrighted materials on the web. But watermarks can also be used to inform the viewer of data (such as photographs and images) as to important aspects of the image such as ownership, location and environmental conditions during the image's creation. This paper examines the use of palindrome images, images in which the data can be flipped in the left-right direction and leave the image untouched. This is similar to words such as RADAR which when flipped left right is still RADAR. An emordnilap image forms a totally different images when flipped. This is similar to words such as STOP which when flipped left right gives the new word POTS. Emordnilap is palindrome spelled backwards. This paper explores the use of MATLAB algorithms to rapidly detect and embed palindrome and emordnilap electronic watermarks.
