A method for determining a definite safe distance between a wirelessly communicating object transponder and at least one anchor gateway in accordance with a two-way ranging method, wherein transmission and reception timestamps are detected for each communication message via the transponder and the at least one anchor gateway, each of the timestamps from the transponder and the at least one anchor gateway together with at least one respective piece of timestamp monitoring information are transmitted to a failsafe computing device, at least one check is implemented via the failsafe computing device, and the definite safe distance is determined via the failsafe computing device aided by the checked timestamps, where timestamp errors occurring during the detection of the timestamps are caused solely by the transponder or alternatively solely the one anchor gateway.

A location verification system according to an embodiment of the present disclosure includes a plurality of base stations located in respective preset areas and transmitting, to an adjacent mobile communication device, location verification information obtained by signing GPS information on the base stations with a private key. It is possible to expect an effect of re-verifying a location of a mobile communication device, such as a drone or a smart car, at a destination, when the mobile communication device has moved to the destination based on GPS information.

A program acquisition method performed by an information processing terminal, includes calculating a degree of matching a first condition that authorizes access to a predetermined program with respect to a condition detected in relation to the information processing terminal, acquiring the predetermined program and storing the acquired predetermined program in a storage in response to the degree of matching being within a predetermined range from a first value indicating that the degree of matching satisfies the first condition, and restricting the access to the predetermined program stored in the storage until the degree of matching indicates the first value.

Techniques for pillar location for a mobile device are described, and may be implemented via a mobile device to identify frequently visited locations and to perform different tasks for the mobile device at the frequented locations. Generally, the described techniques enable a mobile device to generate precise representations of frequented locations known as “pillar locations” without relying on conventional location determination techniques. Further, specific actions can be performed when the mobile device is detected at a pillar location, such as automatically unlocking the mobile device from a locked state.

Technical problems and their solution are disclosed regarding the location of mobile devices requesting services near a site from a server. Embodiments adapt and/or configure the transmitting device near the site, the mobile device communicating with the transmitting device using a short haul wireless communications protocol to deliver a token based upon a key shared with the server but invisible to the mobile device. The server can determine the proximity of the mobile device to the site to control actuation of the requested service or disable the service request, and possibly flushing the service request from the server. Solutions are disclosed for traffic intersections involving one or more traffic lights, elevators in buildings, fire alarms in buildings and valet parking facilities.

A method enables video surveillance service subscribers to share image streams with individual first responder agencies in the event of emergency. A customer administrator selects permissions on each camera via privileged web-browser or mobile device. Permissions enable selection by static meta data such as type, audio, location, motion, recognition, spectrum, and epoch. Setting ranges of time controls access to video streams of present and past epochs. Under control by a customer administrator, a virtual machine dedicated to each responding agency instantiates a video server. A camera is shared by a customer administrator's selection of permissions on each camera via privileged web-browser or mobile device. Video streams of present and past epochs are controlled by ranges of time. A notification is customized for each responding agency and each event by dynamically generating a link to a secure webserver which records geo-location or network identifiers for validation.
