Abstract

Various embodiments are generally directed to the provision and use of geometric location based security systems that use multiple beacons for determining a location. A beacon transmitted from an ultrasound broadcast as well as one or more different wireless broadcasts can be used to geo-locate a device and provide access controls based on the geo-location.

First claim

1 . An apparatus to secure access based on a geographic location, the apparatus comprising:
a processor element; and logic executable by the processor element, the logic to:
receive broadcast information, the broadcast information to include indications of an ultrasound broadcast from an ultrasound beacon transmitter and a wireless broadcast from a wireless beacon transmitter;
construct a geometric shape based on the ultrasound broadcast and the wireless broadcast; and
align the geometric shape with a map of a physical space to form an allowed access area for a device.

2 . The apparatus of claim 1 , the logic to:
receive a request to access a device in the physical space, the request to include an indication of a mobile device, the geometric shape corresponding to a geo-location of the mobile device in the physical space; determine whether the access request is authorized based on a geometric access policy, the geometric access policy to include an indication of a portion of the physical space in which access is authorized; and provide an access token for the mobile device based on the determination that the access request is authorized.

3 . The apparatus of claim 2 , logic to:
determine whether the geometric shape is within the portion of the physical space; and authorize the access request based on the determination that the geometric shape is within the portion of the physical space; or deny the access request based on the determination that the geometric shape is not within the portion of the physical space.

4 . The apparatus of claim 1 , the wireless broadcast being a first wireless broadcast and the wireless beacon transmitter being a first wireless beacon transmitter, the broadcast information to further include indications of a second wireless broadcast from a second wireless beacon transmitter, the logic to construct the geometric shape based on the ultrasound broadcast, the first wireless broadcast, and the second wireless broadcast.

5 . The apparatus of claim 4 , wherein the first wireless broadcast and the second wireless broadcast are different.

6 . The apparatus of claim 1 , the wireless broadcast selected from a group comprising Bluetooth, WiFi, global packet radio service, global positioning system, and infrared.

7 . The apparatus of claim 1 , comprising a network interface coupled to the processor element, the network interface to communicate the broadcast information to the processor element.

8 . At least one machine-readable storage medium comprising instructions that when executed by an access server, cause the access server to:
receive broadcast information, the broadcast information to include indications of an ultrasound broadcast from an ultrasound beacon transmitter and a wireless broadcast from a wireless beacon transmitter; construct a geometric shape based on the ultrasound broadcast and the wireless broadcast; and align the geometric shape with a map of a physical space.

9 . The at least one machine-readable storage medium of claim 8 , the access server caused to:
receive a request to access a device in the physical space, the request to include an indication of a mobile device, the geometric shape corresponding to a geo-location for the mobile device in the physical space; determine whether the access request is authorized based on a geometric access policy; and provide an access token for the mobile device based on the determination that the access request is authorized.

10 . The at least one machine-readable storage medium of claim 9 , the request to include an indication to access a fixed resource from the mobile device.

11 . The at least one machine-readable storage medium of claim 10 , the geometric access policy to include an indication of a portion of the physical space in which access to the fixed resource is authorized.

12 . The at least one machine-readable storage medium of claim 11 , the access server caused to:
determine whether the geometric shape is within the portion of the physical space; and authorize the access request based on the determination that the geometric shape is within the portion of the physical space; or deny the access request based on the determination that the geometric shape is not within the portion of the physical space.

13 . The at least one machine-readable storage medium of claim 8 , the wireless broadcast being a first wireless broadcast and the wireless beacon transmitter being a first wireless beacon transmitter, the broadcast information to further include indications of a second wireless broadcast from a second wireless beacon transmitter, the access server caused to construct the geometric shape based on the ultrasound broadcast, the first wireless broadcast, and the second wireless broadcast.

14 . The at least one machine-readable storage medium of claim 13 , wherein the first wireless broadcast and the second wireless broadcast are different.

15 . At least one machine-readable storage medium comprising instructions that when executed by a mobile device, cause the mobile device to:
send a control signal to an ultrasound beacon receiver, the control signal to include an indication to receive an ultrasound broadcast; send a control signal to a wireless beacon receiver, the control signal to include an indication to receive a wireless broadcast; and transmit broadcast information to an access server, the broadcast information to include indications of the ultrasound broadcast and the wireless broadcast.

16 . The at least one machine-readable storage medium of claim 15 , the mobile device caused to transmit a request to access a fixed resource in a physical space.

17 . The at least one machine-readable storage medium of claim 16 , the mobile device caused to receive an access token to access the fixed resource from the access server.

18 . The at least one machine-readable storage medium of claim 15 , the mobile device caused to:
receive a geometric shape from the access server, the geometric shape corresponding to a location of the apparatus within a physical space, the geometric shape constructed from indications of the ultrasound broadcast and the wireless broadcast; and align the geometric shape with a map of the physical space.

19 . The at least one machine-readable storage medium of claim 18 , the mobile device caused to:
determine whether the geometric shape is within a portion of the physical space, the portion of the physical space corresponding to an area of allowed access to a fixed resource; and access the fixed resource based on the determination that the geometric shape is within the portion of the physical space.

20 . The at least one machine-readable storage medium of claim 15 , the wireless broadcast being a first wireless broadcast and the wireless beacon receiver being a first wireless beacon transmitter, the mobile device caused to send a control signal to a second wireless beacon receiver, the control signal to include an indication to receive a second wireless broadcast, the broadcast information to further include indications of the second wireless broadcast.

21 . The at least one machine-readable storage medium of claim 20 , wherein the first wireless broadcast and the second wireless broadcast are different.

22 . The at least one machine-readable storage medium of claim 15 , the wireless broadcast selected from the group consisting essentially of Bluetooth, WiFi, global packet radio service, global positioning system,
