special_seed = randi([1 255]);
randomized_image = uint8( mod(double(YourImage)+special_seed, 256) );

No there is no function provided for that specific purpose. The code I gave above does one kind of randomization. To reverse use -special_seed instead of + it.

See attached demos for random scrambling and scrambling via Arnold's Cat Map.
