Graphical password system

hello.. we are collge student. we are going to implement one ieee paper.
project name is integration of sound signature in graphical password system. we are creating the password by giving click points on images but in that paper there is no specific any algorithm for image loading at the time of login and registration. so can we implement it without any algorithm.

Well i have spend lot of time with Images in java. Google for BufferedImage class.:o
"so can we implement it without any algorithm. " Yes if you are free to implement new algo.
