Data is concealed using a security technique called steganography in a variety of digital media, including music, video, and photographs. Steganography, also referred to as invisible communication, is the use of a variety of methods to conceal the transmission of a message while maintaining its confidentiality. There are many different steganography techniques, and they vary based on the message to be concealed, the type of file being used as the carrier, the compression algorithm, etc. This work aims to conduct a detailed investigation of two efficient steganographic methods, one from the spatial domain and the other from the transform domain. The outcomes of implementing the Least Significant Bit (LSB) approach and the DWT-based information hiding method for various images are compared. Methods are thoroughly examined and tested from all angles. The number of bits required to disguise the data in the LSB technique ranges from 4 to 7. For varied embedding strengths ranging from 0.01 to 0.5, DWT-based methodology is used. To test the efficacy of these techniques, various images including scenery, animals, and text are taken into consideration. Comparative metrics include Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR). Results indicate that DWT is superior to LSB. The in-depth examination of these steganography methods may give scholars in this area not just understanding and recommendations, but also suggestions for future work.
