Step1: Read a text file which we want to hide.
Step2: Transform it into an array of its binary value.
Step3: Transform this array into its equivalent one dimensional array and compute the array size
Step4: Read the cover image file.
Step5: Transform to its pixel value array.
Step6: For each pixel of the input image; Convert the intensity value of the current pixel into the binary form. Assign one element of the text array into the last bit of the binary value.
Step7: Repeat step6 upto the text array size.
Step8: Save the encoded image.
Step9: Create a text file and read the encoded image.
Step10: Transform the encoded image to its pixel array.
Step11: Pick a pixel and transform to its binary form and pick the 8th bit, store it in another array 'a'(1*8 array).
Step12:Transform a from binary to string and return it to the newly created file.
Step13:Repeat step11 & step12 upto the array size computed in step3.
Step14: End.
