Security and access system based on multi-dimensional location characteristics
View Patent ↗An invention is provided for system security and access based on multi-dimensional location characteristics. The invention includes collecting contextual information characterizing a specific location during a first time period utilizing a contextual data collection device (CDCD), wherein the contextual information indicates specific characteristics of the location and is collected at the location. Then, a contextual location fingerprint (CLF) is created based on the collected contextual information. In general, the CLF is a data space of values mapped over specific period of time. In operation, new contextual information is collected at a location occupied by a device to be verified during a second time period. The new contextual information then is compared to the CLF and authenticating the device fir the new contextual information is within predefined parameters of the CLF.
1. A method for providing system security and access based on multi-dimensional location characteristics, comprising:
collecting contextual information characterizing a specific location during a first time period utilizing a contextual data collection device (CDCD), wherein the contextual information indicates specific characteristics of the location and is collected at the location, and wherein the contextual information includes range information from a single perspective to at least two key materials located at the specific location, and wherein the contextual information further includes measured effect data acquired using dual frequency measurements of dielectric content of intervening material, wherein the measured effect data is a measured effect of the intervening materials on radio frequency (RF) signals received at the CDCD from a remote RF source;
creating a contextual location fingerprint (CLF) based on the collected contextual information, wherein the CLF is a data space of values mapped over specific period of time;
collecting new contextual information at a location occupied by a device to be verified during a second time period, wherein the new contextual information includes range information from the single perspective to at least two of the key materials located at the specific location; and
comparing the new contextual information to the CLF and authenticating the device when the new contextual information is within predefined parameters of the CLF.
2. A method as recited in claim 1 , wherein the contextual information is mapped over time to create the contextual location fingerprint (CLF).
3. A method as recited in claim 1 , further comprising the operation of establishing a token, wherein the token is a private session key.
4. A method as recited in claim 3 , wherein the token is provided to other servers within a predefined proximity of a location hub server.
5. A method as recited in claim 1 , wherein a key material is a door.
6. A method as recited in claim 1 , wherein a key material is a wall.
7. A system for providing system security and access based on multi-dimensional location characteristics, comprising:
a contextual data collection device (CDCD) that collects contextual information characterizing a specific location during a first time period utilizing, wherein the contextual information indicates specific characteristics of the location and is collected at the location, and wherein the contextual information includes range information from a single perspective to at least two key materials located at the specific location, and wherein the contextual information further includes measured effect data acquired using dual frequency measurements of dielectric content of intervening material, wherein the measured effect data is a measured effect of the intervening materials on radio frequency (RF) signals received at the CDCD from a remote RF source;
a device that creates a contextual location fingerprint (CLF) based on the collected contextual information, wherein the CLF is a data space of values mapped over specific period of time; and
a device that compares new contextual information to the CLF and authenticates a device to be verified when the new contextual information is within predefined parameters of the CLF, wherein the new contextual information is collected at a location occupied by a device to be verified during a second time period, and wherein the new contextual information includes range information from the single perspective to at least two of the key materials located at the specific location.
8. A system as recited in claim 7 , wherein the contextual information is mapped over time to create the contextual location fingerprint (CLF).
9. A system as recited in claim 7 , wherein a token is established, the token being a private session key.
10. A system as recited in claim 9 , wherein the token is provided to other servers within a predefined proximity of a location hub server.
11. A system as recited in claim 7 , wherein a key material is a door.
12. A system as recited in claim 7 , wherein a key material is a wall.
