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. The embedding and extracting processes of the algorithms have been discussedGeneral Terms: Adaptive steganography, security, image processingKeywords: Substitution techniques, human visual system (HVS), discrete cosine transform (DCT), integer wavelet transforms, BPCS (bit-plane complexitysteganography), adaptive least-significant-bit (LSB) substitution, pixel-valuedifferencing (PVD), image contrast; mod-4embedding, HVS features, leastsignificant- bit (LSB), adaptive pixel pair matching (APPM)
