Given a number of available layers of source data and a transmission bit budget, we propose an algorithm that determines how many layers should be sent and how many protection bit...
— The paper presents a simple stochastic model of a True Random Number Generator, which extracts randomness from the tracking jitter of a phase-locked loop. The existence of such...
We estimate the speed of texture change by measuring the spread of texture vectors in their feature space. This method allows us to robustly detect even very slow moving objects. B...

This paper proposes RTT-thumbprint to traceback intruders, and to detect stepping-stone intrusion; RTT-thumbprint is a sequence of timestamp pairs of a send packet and its correspo...
A new method improving watermark robustness against both global and local geometrical distortions is presented in this article. The proposed approach is based on a self-reference c...
