A lossless self-recovery watermarking scheme with JPEG-LS compression
Journal of Information Security and Applications, 2021Abstract Due to the rapid development of application for medical images in recent years, the security of medical images becomes more vital. In this paper, a fragile watermarking scheme for medical images is proposed. The proposed scheme first divides the whole medical image into ROI (Regions of Interest) and RONI (Regions of Non-interest).

Polynomial-Based Secret Image Sharing Scheme with Fully Lossless Recovery
International Journal of Digital Crime and Forensics, 2018 Lossless recovery is important for the transmission and storage of image data. In polynomial-based secret image sharing, despite many previous researchers attempted to achieve lossless recovery, none of the proposed work can simultaneously satisfy an efficiency execution and at no cost of some storage capacity.

A novel mapping-based lossless recovery algorithm for VSS
Journal of Real-Time Image Processing, 2016The disadvantages of the existing lossless recovery algorithms in visual secret sharing (VSS) are that n shadow images or complex computation operation (i.e., Lagrange interpolations) is required in the recovering phase. Inspired by this, a novel mapping-based lossless recovery algorithm (MbLRA) for VSS is proposed in this paper. MbLRA at least has two

Lossless image hierarchical recovery based on POB number system
Signal Processing, 2020Abstract This paper proposes an effective method for image tampering localization and recovery. In the proposed scheme, the host image is firstly encrypted by a chaotic system, and then bit-plane separation is conducted on the encrypted image. Afterwards, the certificate watermark and the recovery watermark are calculated respectively on the MSB ...

A novel lossless recovery algorithm for basic matrix-based VSS
Multimedia Tools and Applications, 2017Lossless recovery is very important for visual secret share (VSS). In this paper, a novel lossless recovery algorithm for the basic matrix-based VSS is proposed. The algorithm has the merit of reconstructing secret image losslessly by using simple addition operation. The algorithm proves that the condition of lossless recovery of the secret image is ΞΎ0

Tamper Localization and Lossless Recovery Watermarking Scheme
Communications in Computer and Information Science, 2011Tamper localization and recovery watermarking scheme can be used to protect the integrity and authenticity of medical images. In this paper, a simple tamper localization and recovery scheme that uses lossless compression was proposed. Lossy compression may also be applied when necessary.

Lossless recovery of a VQ index table with embedded secret data
Journal of Visual Communication and Image Representation, 2007This paper proposes a reversible data embedding scheme based on a VQ image compression technique which emphasizes that the original VQ compressed codes can be recovered after data extraction. In this proposed scheme, a VQ codebook, which had already been clustered into three groups, was adopted to achieve secret concealment and data recovery.

In this letter, we introduce a simple turn- on snubber for the conventional bidirectional converter. This snubber notably reduces the current reduction rate of the converter main diodes at turn- off . Hence, the reverse recovery losses, which are the dominant losses in the bidirectional converter, are almost eliminated.
