Abstract

Developments of technology are increasing very fast. One of them is about digital image. Digital image is easy to find in the internet. There is a way to protect the images from copyright theft, watermark is a technique for protecting the copyright of the image in a digital world. There are few things needed to learn in watermarking an image. Converting value from binary to decimal and decimal to binary is needed to convert value and change the least significant bit in one pixel. The pattern that will be used in encode and decode processes are zig-zag pattern and sequence pattern. The program will do encode and decode process using two different patterns. Booth zig-zag or sequence pattern successfully do encode and decode process. The process using zig-zag pattern needs more time than sequence pattern.
