Proposed Approach to Enhanced Multimedia Information Security
Ankita Awasthi, Amit Saxena · 2014
The concept of image security and the word cryptography might be intimidating and complicated. The objective of the research is to design an idea that helps the user and the operations to achieve images security. Nowadays, information or image security is becoming more important in data storage and transmission. Images are widely used in several processes. Therefore, the protection of image data from unauthorized access is important. Steganography plays a significant role in the field of image hiding. Image hiding or encrypting methods and algorithms range from simple spatial domain methods to more complicated and reliable frequency domain ones. Most of the available steganography are mainly used only for single technique at a time but in this research, a new approach is propose to improve steganography technique. This approach is combining two techniques one is cryptography then followed by steganography. In cryptography, symmetric key cryptography are using to encrypt original image to produce cipher image and then this cipher image pass through steganography to produce final image . Performance of the propose approach is also analyzed and showing the expected results based on selected parameters. Expected results are proving the higher security and effectiveness in the performance.
