What is Steganography?

Steganography is a method of hiding secret data, by embedding it into an audio, video, image, or text file. It is one of the methods employed to protect secret or sensitive data from malicious attacks. The word Steganography is derived from two Greek words- ‘stegos’ meaning ‘to cover’ and ‘grayfia’, meaning ‘writing’, thus translating to ‘covered writing’, or ‘hidden writing’.

STEP 1 : Download an image and create a text file (filename.txt).

STEP 2 : Open the command prompt, and list out the documents required for steganography i,e., image and text file. Use the command - “copy /b image.jpg+filename.txt output.jpg”.

STEP 3 : The text that we had in the text file will be hidden in the image as output and when the output image is opened with notepad, the text will be displayed at the bottom.

Perform the above given steps for zip file. Command - “copy /b image.zip+filename.txt output.jpg”.
