Abstract: A verification operating system (VOS) is an intermediary operating system that verifies data of a primary operating system before the primary operating system controls of the computing device. When the computing device is initialized, initial boot processes load the VOS instead of the primary operating system. The VOS performs verification processes on data storing the primary operating system to verify that the primary operating system has not been manipulated or corrupted before passing control of the computing device to the primary operating system. A VOS also may be used to verify an operating system used by a virtual machine (VM). The VOS verifies data storing a VM operating system to be used for requested VMs. If the VOS verifies that the VM OS data is accurate, the VOS provides the VM OS data to a hypervisor for use in a VM.

Abstract: Systems and methods are provided for generating a virtual reality (VR) simulation of a retail store, which simulation is configured and displayed on an immersive VR display device that enables a user to experience the simulated retail store as if it were a physical retail store. The systems enable the user to arrange display cases and other interior store components, and to populate shelves, racks, and the like, with products to be sold in the retail store. A VR platform enables multiple users to synchronously view the VR simulation and make coordinated changes to develop an optimized configuration of the retail store. Marketing, sales, merchant, and other data may be collected, aggregated, and analyzed to identify purchase trends of certain products; the analyzed data may identify user shopping preferences, and the VR platform may generate a customized retail store including only products relevant to a user.
