Transmission of digital content has increases tremendously these days. Privacy and security of the transmitted data has become an important concern in multimedia applications because multimedia data has been an essential part of our lives, from instant messaging applications to social media. For security of the data we use different techniques like cryptography, steganography, and scrambling. Cryptography is one of the main techniques used for information security which includes many forms like digital signatures, authentication etc. and performs system security, confidentiality, data integrity and other functions. This paper works on dual layer security systems using (Elliptic-Curve cryptography) ECC and (Modified Advanced Encryption Standard) MAES called EMAES on Multimedia files (Text, Audio, and Video). Using this approach, unauthorized viewing of the multimedia file can be prevented. Also, this algorithm provides a high level of security and efficiency as compared to existing ones. Comparison of results with other algorithms using parameters like SSIM, FSIM, PSNR and execution time shows that all these parameters are improved 20% or more. The implementation is carried out in MATLAB 2018a.
