Steganography
steganography is all about digital method to convert the secret message into video, audio, photo and text.
For example:- I'm manish and wanted to send the password of premium Netflix account to my friend. If I use facebook platform to share my password then it can be accessible by his employ. But if i hide the text password behind the image and send to my friend then the facebook employ can't see my password they will understand that it is simply image that is share by his friends. So the process I use to hide the password text behind the image is know as steganography.
How is it different from cryptography?
Cryptography and steganography are both methods, used to protect secret data. However, they differ in the respect that cryptography makes the data unreadable, or hides the meaning of the data, while steganography hides the existence of the data.
cryptography is similar to writing a letter in a secret language: people can read it, but won’t understand what it means. However, the existence of a (probably secret) message would be obvious to anyone who sees the letter, and if someone either knows or figures out your secret language, then your message can easily be read.
But in steganography the secret message in invisible ao it can be readable to everyone
How does normal person use it ?
They use steganography to bind the password or personal photo behind the video,photo
How does the hacker use the it?
They use steganography to bind the payload or virus file behind the photo or video so that they can bypass the security system and send it to victim to hacked there device.
