Federated Learning (FL) has emerged as a decentralised machine learning paradigm for distributed systems, particularly in edge and IoT environments. However, ensuring fault tolerance and self-recovery in such scenarios remains challenging, because of the ...

The notion of `mobile adversary,' where the opponent can capture parties in a multi-party protocol dynamically, as long as at any given point in time its capturing capability is limited by a bound on number of parties (processors) it can control, has ...

Watermarking algorithms have been widely applied to the field of image forensics recently. One of these very forensic applications is the protection of images against tampering. For this purpose, we need to design a watermarking algorithm fulfilling two ...

The hypotheses on potential sources of error in an application can be specified in a fault model, which helps testing scenarios that are likely to be buggy. Based on a fault model, we developed custom fault detection mechanisms for providing self-...

To take into account security, invisibility and recovery quality, this work proposes a variable-payload self-recovery fragile watermarking scheme. For each block, the watermarks include the total-watermark with variable number of bits and the basic-...

In this paper, a novel fragile watermarking method is proposed for color image recovery via color filter array interpolation. First we turn a color image into a grey image by color sampling in the form of Bayer patterns. Data of the grey image which is ...

Wireless sensor networks (WSN) have become increasingly one of the most promising and interesting areas over the past few years. But the character of constrained resources makes it vulnerable to Denial of Service (DoS) attacks, resulting in a large ...

In this paper, we propose a scheme can be divided into two parts: one is about robust embedding of dual visual watermarks using DWT and Singular Value Decomposition (SVD), the other part is about tamper detection and self-recovery algorithm of color ...

In this paper, a self-recovery fragile watermarking scheme for image authentication is proposed to improve the performance of tamper detection and tamper recovery. The proposed scheme embeds the encrypted feature comprising 6-bit recovery data and 2-bit ...

This paper presents a novel image watermarking scheme for both tamper detection and tampered image recovery. The basic principle of this scheme is to compress per block of the original image using SPIHT (Set Partitioning in Hierarchical Trees), then ...

Microreboot is one of the most efficient self recovery technologies for mission-critical system. But some limitations still exist in the existing microreboot methods such as demand of componentization and loosing coupling etc. In order to eliminate ...

The digital image watermarking field addresses the problem of digital image authentication and integrity. In this paper we propose a novel color image watermarking scheme based on image self-embedding and self-recovery techniques. The main idea of this ...

In this paper, we will describe an integrated system for synthesizing self-recovering microarchitectures called ${\cal SYNCERE}$. In the ${\cal SYNCERE}$model for self-recovery, transient faults are detected using duplication and comparison, while ...
