The message: student name 1 - student name 2 - student name 3 Choose a file from your computer: mp3 song, png picture, … Extract the message to appropriate format, insert this message into the chosen file. Make sure, after insert the message into the file, you can still listen mp3, open the picture. Note: you need to propose an algorithm for insertion the message into the chosen file. Prove that, it is impossible, or very difficult, for the bad people if they want to take the hidden message out.

The length of the message is hidden in only the first pixel, therefore the message length can't be more than 63 character.
To get the hidden message out, use:
