On JPEG2000 Error Concealment Attacks

چکیده
In this work, JPEG2000 error resilience options and error concealment strategies are discussed and evaluated. Error resilience options and error concealment strategies have been employed to mimic attacks against selective / partial JPEG2000 encryption schemes. Thus the security evaluation of these selective / partial encryption schemes relies on the proper working of the JPEG2000 error concealment. Recommendations for JPEG2000 encryption given in previous work have to be reassessed on the basis of our results. Improvements to the error concealment code of the JPEG2000 reference software JJ2000 are presented.

Data hiding error concealment for JPEG2000 images
This paper presents an error concealment technique for image transmission in JPEG2000 for the lowest frequency coefficients. The proposed method uses the layer structure that is a feature of the JPEG2000. The most significant layer is hidden in place of the lowest layer of the bit stream. After transmission this embedded layer is used for error concealment. The bit stream encoded using the prop...
متن کاملError Control and Concealment of Jpeg2000 Coded Image Data in Error Prone Environments
In this contribution we investigate the error robustness tools offered by the JPEG2000 coding standard. Error robustness is supported on entropy coding level and packet level. A synchronization loss caused by a packet loss can be prevented if marker segments are inserted into the code stream. However, a packet loss and the related loss of wavelet coefficients causes a severe visual distortion. ...
متن کاملNew Error Concealment Method in JPEG2000 Images
JPEG2000 image compression standard provides good compression efficiency in image coding. But the resulted JPEG2000 bit stream is very sensitive to noise error and packet loss. Both of the error sources result in loss of some least significant bits in the decoded coefficients of compressed image. The current practice is filling the lost bits with zero [1]. This Zero Filling (ZF) Error Concealme...
متن کاملEfficient error handling for video and still picture standards
This paper describes new methods for errors handling at the decoder side, when channel noise affects the transmission of the compressed stream. The proposed error detection techniques are applied to MPEG-4 standard video, but can be also used for general video and still picture standards in which Inverse Quantization clipping or resynchronization markers are present as MPEG-2, H263, H26L, JPEG ...
متن کاملA reliability engineering approach to digital watermark evaluation
Robust watermarks are evaluated in terms of image fidelity and robustness. We extend this framework and apply reliability testing to robust watermark evaluation. Reliability is the probability that a watermarking algorithm will correctly detect or decode a watermark for a specified fidelity requirement under a given set of attacks and images. In reliability testing, a system is evaluated in ter...
