Explain using an example how data can be encoded

Question

anonymous · Answer

There are many ways to encode your data when you use a difficult algorithm it will be harder to be decoded by others .... an example : kaiser algorithm for encoding .... It's a very simple algorithm : It just changes the symbol used for the letter. for example on it : replace any character with the one is located directly after the three characters in the ascii Table .. A will be replaced by D B will be replaced by E ..... Z will be replaced by C see this topic : it uses The Kaiser algorithm in another way : http://courses.gdeyoung.com/pages/encryption/ADFGVX.php .... As I've said before there is many ways to encode data .... http://www.cs.tut.fi/~jkorpela/chars.html http://en.wikipedia.org/wiki/Lossy_compression If you are interested in "information theory" , there are many ways to encode data in it . http://www.data-compression.com/lossless.html http://www.maximumcompression.com/algoritms.php if you need compressing with encoding try : LZW encoding : http://decsai.ugr.es/ccd/complementario/teoria/cse391-lecture05.pdf http://en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Welch
