The secret message and ordinary objects can be an image, text, audio, files etc. … Steganography is required to send the message without disclosing the presence of the message. This is how steganography differs from cryptography.
What is image steganography?
Image steganography refers to hiding information i.e. text, images or audio files in another image or video files. The current project aims to use steganography for an image with another image using spatial domain technique. This hidden information can be retrieved only through proper decoding technique.
How do you find steganography?
The easiest way for a SOC to detect steganography is to simply invest in an email security or data-loss prevention tool that has such capabilities built in. All you have to do is point the alerts to your monitoring system and respond.

How is audio steganography implemented?
Convert the samples obtained into bytes of binary data and store them in an array. Find the length of the audio signal(number of bytes) and store it as N. Choose a key for steganography of length K. Check if the length of message and key together is less than or equal to one-eighth of the audio length.
