Abstract: A system and method for authentication. In some embodiments, the method includes displaying a plurality of objects to a user's left eye and to the user's right eye, and monitoring the user's eye positions while the user looks at a subset of the displayed objects, one at a time. The method may further include comparing an angular offset for an object of the plurality of objects to a vergence measured for the user's eyes while the user looks at the object.

Abstract: An electronic device, and an operation method thereof, are disclosed. The electronic device may include a memory; and a processor configured to execute at least one operating system executed in a first region allowing an operation based on a first authority; execute at least one application executed in a second region allowing an operation based on a second authority; receive a first authority policy from a server; obtain a second authority policy from the at least one application; and in response to detection of access to at least one device resource by the at least one application, configure authority of access to the at least one device resource, according to a third authority policy based on the first authority policy and the second authority policy, by using an authority determination module executed in a third region allowing an operation based on a third authority.
