Abstract: A system for authenticating a first user to a second user is described. The system includes a memory device having instructions stored thereon, a camera device associated with the second user, and a processor in communication with the memory device and the camera device wherein the processor is configured to execute the instructions. The instructions cause the processor to establish, based upon data received at the camera device from a first user device associated with the first user, a communication channel with the first user device and receive, via the communication channel, a mobile identification (mID) provided by the first user device. The instructions also cause the processor to determine whether to authenticate the first user based upon credential data extracted from the mID provided by the first user and initiate, based upon the determination, feedback to the second user indicating whether the first user was authenticated.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer-readable storage medium, for pre-boot network-based authentication. In some implementations, a computing device enters a UEFI environment upon powering on the computing device. While in the UEFI environment, the computing device restricts booting of an operating system of the computing device, accesses a signed certificate corresponding to a particular user, sends a verification request to a server system over a communication network, and receives a verification response from the server system over the communication network. In response to receiving the verification response, the computing device (i) enables the operating system to boot and (ii) verifies the identity of the particular user to the operating system such that the operating system logs in the particular user without requiring further proof of identity for the particular user.

Abstract: A computer-implemented method includes receiving a request for information indicative of venues that are located within a geographic region of interest, accessing user data for one or more users of a social networking platform, identifying, in the accessed user data, data indicative of one or more affirmative actions that are performed for the particular venue by at least one of the one or more users, and generating a popularity score for the particular venue, determining one or more popular venues, with a popular venue being associated with an increased popularity score relative to popularity scores of other of the multiple venues located with the geographic region of interest, and for a determined popular venue, generating data indicative of a type of user of the social networking platform who performs one or more affirmative actions for the determined popular venue.
