Review for ICDCS20

[ICDCS20] - Sybil-Resistant

A Sybil-Resist Truth Discovery Framework for Mobile Crowdsensing

(IEEE ICDCS'20)

"In this paper, we proposed a Sybil-resistant truth discovery framework for MCS, which ensures high accuracy under the Sybil attack."

Introduction

main idea: assigns higher weights to reliable users

disadvantage: a user could conduct the Sybil attack by submitting data using multiple accounts for various motives

example: a rapacious user may want to receive more rewards without contributing extra efforts

Although many Sybil attack defense mechanisms do not consider the behaviors of mobile users in MCS and cannot be applied to MCS directly.
