| Abstract | The objective of this research is to study and develop the prototype of traceability system using LSBsteganography in image files with Base64 and MD5 encoding. The research methodology follows SDLC processcomposed of problem investigation, system analysis and design, system development and system testing. Researchtool is the prototype of traceability system using LSB steganography in image files with Base64 and MD5 encoding,developed from HTML5, JAVA and PHP scripts connecting to MySQL database on Apache Web Server. Files wereconverted to ASCII binary bits and encoded with Base64 and MD5 sequentially, then transformed to binary bitsagain to replace the last bit of each pixel which was converted from the original image file bit by bit.From the result of the experiment on the image files which have different resolution (72 pixel/inch), the file sizeof converted image files were not different from the original image files. When unhidden and decoding, thecomplete original files were discovered and traceable. It can be concluded that the prototype of traceability systemusing LSB steganography in image files with Base64 and MD5 encoding is efficient in terms of processing time andnon-different file size from original. |
