An Improved Approach of Image Steganography Based on Least Significant Bit Technique for Secure Communication in Cloud

Cloud computing allows for a simple, distributed pool of reconfigurable computers with widespread network connectivity. But maintaining data security and privacy is very difficult. In order to guarantee the privacy and security of data in cloud computing, this study developed an efficient and enhanced method that involves concealing data inside pictures. The authors have proposed Multi Level Encryption Algorithm (MLEA) and Two-Level EncryptionAlgorithm (TLEA) and also processed the image in various steps to achieve better security. The objective is to design and develop an image steganography method based on the Least Significant Bit (LSB) technique that can secure the data during sharing or storing. The authors used the LSB technique of image steganography and encrypted data using MLEA and TLEA. The authors compared different methods and proved their research provides better security than the existing ones. This research demonstrates that the proposed method has performance with an average of 19.7814% better than other existing schemes.
