Nonparametric steganalysis of QIM data hiding using approximate entropy
This paper proposes a nonparametric steganalysis method for quantization index modulation (QIM) based steganography. The proposed steganalysis method uses irregularity (or randomness) in the test-image to distinguish between the coverand the stego-image. We have shown that plain-quantization (quantization without message embedding) induces regularity in the resulting quantized-image; whereas me...
متن کاملImage Error concealment Based on QIM Data Hiding in Dual-Tree Complex Wavelets
Transmission of block-coded images through error-prone radio mobile channel often results in lost blocks. Error concealment (EC) techniques exploit inherent redundancy and reduce visual artifacts through post-processing at the decoder side. In this paper, we propose an efficient quantization index modulation (QIM)-based data hiding scheme using dual-tree complex wavelet transform (DTCWT) for th...
متن کاملIntegrity verification for XML data
The success of the Internet has made the communication very easy between parties and XML is one of the most used standard for information representation and exchange. A huge amount of data is crossing the Internet on the daily basis. Since the Internet is an unreliable network, XML data can be easily captured and tampered by unauthorized users. This study is proposing a scheme that uses fragile...
متن کاملProtection Mechanism for Compressed Image over WI-MAX Using QIM Data Hiding
Watermarking is highly demanding in recent times for the protection of multimedia data in network environment from illegal use of data and from the transmission losses due to the fading. To this aim, this dissertation proposes a protection mechanism for discrete transform based compressed image through error concealment (EC) without affecting the compatibility of standard JPEG coding. In this p...
