Blockchain has been an emerging technology, which comprises lots of fields such as distributed systems and Internet Things (IoT). As is well known, blockchain the underlying technology bitcoin, whose initial motivation derived from economic incentives. Therefore, components (e.g., consensus mechanism) can be constructed toward view game theory. In this paper, we highlight combination theory blockchain, including rational smart contracts, theoretic attacks, mining strategies. When put...

Collaborative perception enables autonomous vehicles to exchange sensor data among each other achieve cooperative object classification, which is considered an effective means improve the accuracy of connected (CAVs). To protect information privacy in perception, we propose a lightweight, privacy-preserving classification framework that allows CAVs raw (e.g., images captured by HD camera), without leaking private information. Leveraging chaotic encryption and additive secret sharing...

This paper introduces a novel bi-directional con-volutional framework to cope with the large-variance scale problem in scene text detection.
