Data Hiding and Authentication Scheme for Medical Images Using Double POB
Applied SciencesTo protect the security of medical images and to improve the embedding ability of data in encrypted medical images, this paper proposes a permutation ordered binary (POB) number system-based hiding and authentication scheme for medical images, which ...

Digital forensics formats: seeking a digital preservation storage format for web archiving [PDF]
, 2011 In this paper we discuss archival storage formats from the point of view of digital curation and preservation. Considering established approaches to data management as our jumping off point, we selected seven format attributes which are core to the ...

Tamper Detection and Recovery for Medical Images Using Near-lossless Information Hiding Technique [PDF]
Journal of Digital Imaging, 2007 Digital medical images are very easy to be modified for illegal purposes. For example, microcalcification in mammography is an important diagnostic clue, and it can be wiped off intentionally for insurance purposes or added intentionally into a normal mammography.

Compression-Assisted Adaptive ECC and RAID Scattering for NAND Flash Storage Devices
Sensors, 2020 NAND flash memory-based storage devices are vulnerable to errors induced by NAND flash memory cells. Error-correction codes (ECCs) are integrated into the flash memory controller to correct errors in flash memory. However, since ECCs show inherent limits

Almost Lossless Analog Signal Separation
, 2013 We propose an information-theoretic framework for analog signal separation. Specifically, we consider the problem of recovering two analog signals from a noiseless sum of linear measurements of the signals. Our framework is inspired by the groundbreaking

Efficient and Robust Compressed Sensing Using Optimized Expander Graphs [PDF]
, 2009 Expander graphs have been recently proposed to construct efficient compressed sensing algorithms. In particular, it has been shown that any n-dimensional vector that is k-sparse can be fully recovered using O(klog n) measurements and only O(klog n ...
