报告题目: Mobile App Reputation Manipulation: Characteristics and Detection 

 

内容简介:

Abstract: Driven by monetary reward, some mobile app developers turn to the underground market to buy positive reviews instead of doing legal advertisements. These promotion reviews are either directly posted in app stores like iTunes and Google Play, or published on some popular websites with many app users. In this talk, I will first introduce our research on unveiling this underground market and statistically analyzing the promotion incentives, characteristics of promoted apps and suspicious reviewers. Then we propose several robust and effective mechanisms to identify both promoted apps and the groups of hired promoters. Finally, some ongoing research directions will be discussed.
