Steganography Technique Based on DCT Coefficients
The least significant-bit (LSB) based techniques are very popular for steganography in spatial domain. The simplest LSB technique simply replaces the LSB in the cover image with the bits from secret information. Further advanced techniques use some criteria to identify the pixels in which LSB(s) can be replaced with the bits of secret information. In DCT based technique insertion of secret info...
متن کاملRandomized Embedding Scheme Based on DCT Coefficients for Image Steganography
Main goal of steganography is to communicate securely in a completely undetectable manner. It is an art of hiding secret data in an innocently looking dummy container. In the Steganographic process, communication is masked to make the hidden message not discernible to the observer. Hidden message may be textual or image. In this paper, a novel image steganography method based on randomized bit ...

متن کاملSteganography: DCT Coefficients Reparation Technique in JPEG Image
Due to the ever-growing usage of the computer, it has led to a rapid increment in the data that is being exchanged, published and stored in an assortment of digital form. This phenomenon has urged an active participation in the research area of the security domain. One of the main areas of this security domain in providing confidentiality, authentication and data integrity is steganography. Thi...
متن کاملCompact and Robust Fingerprints Using DCT Coefficients of Key Blocks
In this paper, we present a novel fingerprinting method for image authentication, the fingerprint length of which is very short (only 81 bytes) and independent on image sizes. First, we extract features based on the block DCT coefficients of images, and binarize the feature map to get key blocks. Then we apply Principal Components Analysis (PCA) to the DCT Coefficients of key blocks. Finally, w...
