Robust lossless image data hiding designed for semi-fragile image authentication
, 2008 Recently, among various data hiding techniques, a new subset, lossless data hiding, has received increasing interest. Most of the existing lossless data hiding algorithms are, however, fragile in the sense that the hidden data cannot be extracted out ...

Lossless Snubber Circuits For Current Doubler Rectifiers To Reduce Reverse-Recovery Losses
, 2003 Current doubler rectifier (CDR) is one of the best candidates for high output current DC-DC converters. In this paper, several conventional CDR snubber circuits are evaluated, and two passive lossless snubber circuits for the CDR are proposed to reduce ...

Robust lossless data hiding using clustering and statistical quantity histogram
, 2012 Lossless data hiding methods usually fail to recover the hidden messages completely when the watermarked images are attacked. Therefore, the robust lossless data hiding (RLDH), or the robust reversible watermarking technique, is urgently needed to ...

Lossless Recovery of Multiple Decryption Capability and Progressive Visual Secret Sharing
International Journal of Grid and Distributed Computing, 2016 In order to solve the problem of non-restoration of PVSS, in this paper, we propose a method to recover the secret image without using the Boolean operation of the matrix matrix. In the lossless recovery process, each column base matrix will be "and" and "exclusive or" operation to get the original image anti-color image, and then the image can be ...
