US Patent 10210482 Location verification using networked client peripherals

A system verifies the location of a first person during a specified period by sending random alerts to the smart phone of the first person. A user must respond to the alerts. A second person defines acceptable locations. The smart phone has location measuring capability, such as a GPS or connection to a WAN. The identity of the user can be verified by requiring the input of a security code that also gives the user access to confidential information of the first person.
