AuCFSR: Authentication and Color Face Self-Recovery Using Novel 2D Hyperchaotic System and Deep Learning Models [PDF]

Sensors, 2023
Color face images are often transmitted over public channels, where they are vulnerable to tampering attacks. To address this problem, the present paper introduces a novel scheme called Authentication and Color Face Self-Recovery (AuCFSR) for ensuring ...

Self-recovery reversible image watermarking algorithm. [PDF]

PLoS One, 2018
The integrity of image content is essential, although most watermarking algorithms can achieve image authentication but not automatically repair damaged areas or restore the original image. In this paper, a self-recovery reversible image watermarking algorithm is proposed to recover the tampered areas effectively.

Self-recovery in server programs [PDF]

Proceedings of the 2009 international symposium on Memory management, 2009
It is important that long running server programs retain availability amidst software failures. However, server programs do fail and one of the important causes of failures in server programs is due to memory errors. Software bugs in the server code like buffer overflows, integer overflows, etc.
