    Abstract: This study presents a modification of odd and even watermark 
  technique. Suggested modification is based on optimizing the selection of pixels 
  which values will be modified to be odd or even. Least frequent pixels in either 
  odd or even values will be modified. However, the least the modifications of 
  pixel’s values, makes cover image 
  more reliable. The process of embedding and extracting the hidden watermark 
  is explained. Analysis of security achieved is performed.
