“…Besides the standard security strategies, such as on-device and network encryption, others will need to be rethought, especially in this new context [102], [103]. For example, researchers have begun considering the specific AR operating system [104] (from underlying platform perspective), the surroundings information collection rules or retention policies [105] (from sensing perspective), the object access governing [106], [107] (from data access perspective), and the trusted renderer [108], [109] (from output perspective). In addition to these technical solutions, the privacy and security challenges for AR systems also call for social, policy, or legal approaches [110].…”
