How to secretly hide messages in pictures

There is a big difference between privacy and secrecy. Privacy is when you have something and you do not mind others knowing it until and unless people have access to it. For example, your bank details which people know you have but the details are safe until others have access to it. And, secrecy means when you do not want people to know that even something existed. This may be some form of a message which you want to convey to a single person and it should be known by the others. Another example can be writing messages with the secret ink which can be deferred later with the use of some chemicals. The art of hiding messages in pictures is called stenography. And owing to this digital age such technology has gained new heights. You will never understand that an image has a message until the right tools or passwords are used which breaks the message. This article focuses the same and explains different ways of how you can store the secret messages in pictures.

You can find a lot of pictures or you can edit one in the MS Paint. This method combines the image with the text. The image looks very simple unless one looks at the specific position where the secret message is hidden. This method requires creating a BMP file which maybe a picture and the text in the TXT format may be in the notes. Then go to the Command prompt and type: copy “<image file path>” + “<text file path>” “<new image path>”. Name the image whatever you want to name it as. If a person opens this file with paint, he will see the normal image, but if he opens it with the Note, he will see the secret message hidden at the bottom.
