Abstract: A secure environment is unattainable without the implementation of encryption technology. Given that images constitute a significant portion of multimedia data, safeguarding them is crucial in the modern context. The major challenge lies in how we can effectively protect our data. Encryption involves transforming a piece of information by encoding it such that only authorized individuals can decode, read, and understand it. This protects the information from unauthorized access by malicious entities. The encryption process involves subjecting the data to a series of mathematical transformations, producing an alternative form of the original data. This sequence of mathematical operations is known as an algorithm. In this paper, we have conducted a survey of various research papers and reviewed existing encryption techniques. Based on our survey, we also discuss the concept of two-way encryption, analyzing it in conjunction with the Data Encryption Standard (DES) for improved security.
Keywords: Encryption, Encoding, multimedia, confidentiality, integrity, authenticity, cryptography.
