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

is there any function in matlab that convert an image to random image and encrypt the image with specified seed?

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.
