A Secured Data Hiding Technique Using Video Sequences
Secret communication using the Compressed Video file as cover medium and data hiding in compressed video. Unlike data hiding in images and raw video which operates on the images themselves in the spatial or transformed domain which are vulnerable to steganalysis, we target the motion vectors used to encode and reconstruct both the forward predictive (P)-frame and bidirectional (B)frames in comp...
متن کاملDigital Image Data Hiding Using Side Information
Robustness is a key issue for many prospective applications of data hiding technologies. The proposal to take into account side information at the encoder has meant a noteworthy advance in the quest for better data hiding methods. Still, the true impact of the advantages theoretically derived from this groundbreaking idea has not been sufficiently founded in practice. Departing from this situat...
متن کاملAn Enhanced Method for Data Hiding using 2-Bit XOR in Image Steganography
As we all know security is needed when we want to send data over any medium so this requires a secure medium to send data. That’s why steganography comes in mind whose aim is to send data securely without knowing of any hacker. In this paper, a new technique is projected whose aim is to keep secrete communication intact. The proposed method blends the advantage of 2 bit LSB and XOR operation. I...
متن کاملAn Enhanced Data Hiding Approach using Pixel Mapping Method with Optimal Substitution Approach
Data Hiding is one of the challenging issues in the field of Network Security. Unlike cryptography, Steganography is used to hide the existence of secret message by embedding the message behind any cover object like image, text, audio, video files. Various authors proposed, various methods for hiding secret information behind gray scale images such as least significant method, gray level modifi...
متن کاملHi-tech authentication for pslette images using digital signature and data hiding
A scheme that integrates digital signature and data hiding to provide hi–tech authentication for palette images is proposed in this paper. The scheme extracts digital signature from the original palette image and embeds it back into the same palette image, avoiding additional signature file. Digital signature generation is employed using elliptic curve based public key cryptosystem. The perform...
