If a entry is marked with line-shift coding, it is particularly awkward to subscribe to the encoding if the archive is in paper format. (Kessler, 2001)- Word-Shift Coding: In word shifting coding, code words are coded into a document by shifting the horizontal locations of words within text lines, while maintaining a natural spacing appearance. development the Alternate Methods: 1- syntactical methods; 2- Semantic methods2- In images:To fur data in images, concord palette...
