Enhancing Digital Data Security Using RSA Encryption and Digital Watermarking

Abstract

Encryption and data protection techniques are among the most critical topics in the digital age, as there is an increasing need to secure information against unauthorized access, particularly in digital media such as videos. This research investigates the integration of RSA encryption and digital watermarking techniques to secure and protect data.

The study explores how RSA encryption is utilized to protect digital data through the application of a public key for encryption and a private key for decryption. This technique is combined with digital watermarking to safeguard intellectual property rights, where digital watermarks are embedded into the protected data for tracking its origin and ensuring its authenticity.

These techniques were applied to a set of video data, and the impact of encryption on image quality was measured using metrics such as PSNR (Peak Signal-to-Noise Ratio) and SSIM (Structural Similarity Index). The results show that while RSA encryption causes a slight reduction in image quality, the effect on the clarity of the data is minimal. The experiment also demonstrated the effectiveness of integrating watermarking with encryption to protect data from manipulation and unauthorized duplication.

The aim of this study is to enhance information security and protection, and it provides recommendations for future research in hybrid encryption and advanced digital watermarking techniques.
