Privacy Preservation Using Data Hiding and Data Concealing with Steganography and Cryptography

The research paper presents a thorough investigation of data-hiding techniques involving cryptography and steganography. Its main focus is on providing secure methods for transmitting and storing confidential information. The paper delves into the foundational principles, algorithms, and techniques employed in both cryptography and steganography, including substitution ciphers, symmetric and asymmetric key encryption, and LSB-based steganography. The study evaluates the effectiveness of these techniques using various metrics, such as security, capacity, and perceptibility. In conclusion, the paper summarizes its key findings, highlights the advantages and limitations of data hiding using cryptography and steganography, and offers a proposed model to address challenges in data hiding, such as database and storage security, privacy protections, and information flow control. The data input can be in the form of text, audio, video, or an image with an accompanying cover image, and the resulting output is transformed into a blurred image using Gaussian blur. Overall, this research serves as a valuable resource for individuals and organizations seeking to secure their data in a digital environment.
