Image Steganography Using Multi-level Hiding Technique
Abstract: ABSTRACTSteganography is the art of hiding secret information in the innocent-looking cover media but the concern of the sender of the secret data remains that the secret communication embedded should not be deciphered by a hacker or examiner. Presently, single level of hiding of the secret message in the cover medium is resorted to. This paper presents a novel idea of multi-level hiding (MLH) of the secret information in the …

An Evolution of the Pixel Embedding Techniques in Image Based Adaptive Steganography
Abstract: The word “Steganography” was basically derived from the Greek words with the meaning “covered writing.” This paper presents some of the main adaptive image steganography approaches. Many algorithms have been presented; in almost all the algorithms the approach is to embed the secret data in the images. Here we are discussing about adaptive steganography which is based upon spatial domain and frequency domain with an additional layer of mathematical model. …

Lossless and Reversible Data Hiding in Encrypted Images with Public Key Cryptography
Abstract: In this paper, system uses the cryptography and steganography concept, which proposes a lossless, reversible, and combined data hiding methods for images encrypted by public key cryptosystems with probabilistic and homomorphic properties. In the lossless method, pixels of encrypted images are replaced with new values to embed additional data into LSB-planes of ciphertext pixels by multiple layer wet paper coding. Thus, original data can be directly extracted from encrypted image, …
