Abstract:
In today’s world, the progress of communication technology plays a role in our everyday lives. The internet and the conversion of data into forms have significantly expanded the sharing of information leading to fast-paced growth. Despite having secure methods available, safeguarding data remains a top priority. This study aims to improve the security and durability of data transmission by combining steganography and cryptography techniques. Steganography, which involves hiding messages within another medium, and cryptography which entails encrypting messages using keys are both effective ways to ensure data security. The research delves into combinations of algorithms that integrate steganography and cryptography examining their impact on enhancing security. It categorizes methods based on technical and non-technical aspects as well as their domains. Moreover, it underscores the importance of data security in media formats such as images, videos, and audio. In analyzing message lengths noticeable character patterns were observed in both Vigenère Cipher and Elliptic Curve Cryptography. In short messages "s" was prominent in the Vigenère Cipher accounting for 26.3% of occurrences while Elliptic Curve Cryptography showed a prevalence of "t" at 3.9%. Medium-length messages continued to show the dominance of "s" in the Vigenère Cipher at 22.5% while Elliptic Curve Cryptography highlighted "p" as a character at 4.3%. Lastly, longer messages maintained the prevalence of "s" in the Vigenère Cipher at 24.3% with "v" emerging as dominant in Elliptic Curve Cryptography at 3.9%. These findings show that combining steganography and cryptography methods can greatly enhance the protection of multimedia data.
