Separable Reversible Data Hiding In Encrypted Image Using Modified Least Significant Bit and Virtual Embedding

Nowadays digital communication has become an essential part of our daily activities. A lot of applications are internet-based and it is important that communication be made secret especially if it involves exchange of confidential information. As a result, the security of information passed over an open channel has become a fundamental issue and therefore, the confidentiality and data integrity are required to protect against unauthorized access and use. This has led to an unstable growth in the field of information hiding. Cryptography and steganography are the two popular methods available to provide security. Using cryptography, the data is transformed into some other gibberish form and then the encrypted data is transmitted. In steganography, the data is embedded in an image without affecting the quality of the image and that image will be transmitted. This paper proposes a new method for embedding the data inside the image using ordinal virtual embedding technique and also modification of data.
