Security and Privacy of Augmented Reality Systems

Augmented Reality (AR) is a type of system that can enhance user perception by overlaying computer-generated content over real-world scenes, making them increasingly popular among mass consumers, in industry, and even in military training. In order to support immersive and realistic user experience, AR systems rely on real-time sensing through various types of sensors to understand the physical environment, make intelligent decisions, and render virtual objects in a well-managed way. However, recent studies on AR show that existing AR systems have many vulnerabilities, which attackers can leverage to manipulate AR applications or infer sensitive information about AR users. This chapter will research the literature on AR systems’ security and privacy. Specifically, this chapter will focus on input security, input privacy, and output security of excising AR systems. Vulnerabilities and existing countermeasures are discussed under each topic.
