Scrambling and descrambling of an image using chaotic map

[Sanpreet Singh]

Hello everyone.My question is - I want to make my image unreadable
while transmitting it, using chaotic map(arnold cat map, logistic
maps, bakers map or henon map.To know more about chaotic map one can
visit the site http://en.wikipedia.org/wiki/List_of_chaotic_maps.
#I donot know how to do scrambling and descrambling of my image. In
simple words to encrypt it and then decrypt it using chaotic maps.
#I know logic behind this - Key will be used to make our original
image into unreadable image and same key is used to decode it. I donot
know how to encode and decode it. I need to make key using chaotic
map.
#If anyone can help me to make a code to do scrambling and
descrambling of input image with the help of chaotic map, It would be
a great help.
