Abstract
The amount of data shared online today is increasing. Data security is therefore cited as a significant problem while processing data exchanges through the Internet. Everyone needs the security of their data during communication processes. The science and art of steganography is the concealment of one audio, message, video, or image by embedding another audio, message, video, or image in its place. It is employed to protect sensitive data against malicious assaults. In order to detect the numerous methods employed with digital steganography, this study seeks to identify the primary image-based mediums. As a result, in the spatial domain of the digital medium, the LSB approach was mostly employed, whereas in the transform domain, DTC and DWT were separated as the primary techniques. Due to its simplicity and large embedding capacity, the spatial domain was the most frequently used domain in digital steganography.
