متن کاملInformation Hiding in Video Files Using Frequency Domain
Video Steganography is a technique that is used to transmit information by modifying video frames in an imperceptible manner and depending on the weakness of the Human Visual System (HVS) in distinguishing the simple differences between colored images. This paper is about embedding encrypted information (texts and gray images) which have been encrypted using RSA technique at sender side in vide...
متن کاملSecure Data-Hiding in Multimedia Using NMF
This paper presents a novel data-hiding scheme for multimedia data using non-negative matrix factorization (NMF). Nonnegative feature space (basis matrix) is estimated using the NMF-framework from the sample set of multimedia objects. Subsequently, using a secret key a subspace (basis vector) of the estimated basis matrix is used to decompose the host data for information embedding and detectio...
متن کاملSteganographic Techniques for Hiding Data in SWF Files
Small Web Format (SWF) or Flash files are widely used on the Internet to provide Rich Internet Applications (RIAs). This makes SWF files an excellent candidate for disseminating hidden data. However, digital forensic investigators are unable to detect and extract the hidden data because limited information is available about the techniques used to hide data in SWF files. This paper investigates...
