Abstract

A system and method for efficiently establishing patterns of behavior for location-aware monitoring applications. An administrator registers a trackable entity with a tracking service by providing identification of at least the trackable entity, a point of origin and a destination. To identify and select paths between the point of origin and the destination, the tracking service accesses crowdsourced information corresponding to the history of movements of trackable entities between the point of origin and the destination. The tracking service identifies intermediate locales along the selected paths and determines an expected duration of stay for each of the intermediate locales based on the history of movements. As the tracking service monitors the movement of the trackable entity, the tracking service generates alerts responsive to determining the trackable entity stopped at an unallowed intermediate locale or determining a duration of stay at an identified intermediate locale exceeds an expected duration of stay.

Claims

1. A system comprising:

a trackable entity comprising a trackable mobile device carried by a person of interest, said device being trackable by a global positioning system; and

a server configured to;

receive, from a computing device, an identification of the trackable entity;

receive, from the computing device, an identification of each of a point of origin and a destination without receiving an identification of a path between the point of origin and destination;

access a database to identify, prior to movement of the trackable entity, one or more paths between the point of origin and the destination based on a history of movements of trackable entities comprising mobile devices carried by persons walking between the point of origin and the destination, wherein the trackable entities do not include the trackable entity;

receive global positioning system related data indicative of movement of the trackable entity; and

generate an alert responsive to determining a movement of the trackable entity varies from the one or more paths;

wherein the server is further configured to;

identify one or more intermediate locales along the identified one or more paths;

determine an expected duration of stay for each of the one or more intermediate locales based on the history of movements; and

adjust an expected duration of stay for an intermediate locale based on one or more of an occupancy of the intermediate locale, weather, and traffic reports.

2. The system as recited in claim 1 wherein determining a movement of the trackable entity varies from the one or more paths comprises determining the trackable entity has been at an identified intermediate locale for a time exceeding an expected duration of stay.

3. The system as recited in claim 1, wherein the server is further configured to identify the one or more paths and the expected durations of stay based on additional parameters comprising one or more of a particular time of day, a particular day of the week and a particular month.

4. The system as recited in claim 1, wherein the server is further configured to identify the one or more paths based on additional parameters comprising interests and hobbies of the trackable entity.

5. The system as recited in claim 1, wherein determining a movement of the trackable entity varies from the one or more paths comprises determining the trackable entity no longer sends geographical location information for tracking movement of the trackable entity.

6. The system as recited in claim 1, wherein the server is further configured to:

map the identified one or more paths to routes from a routes database; and

send the generated alert to a destination device comprising one or more of a mobile device and a computer.

7. The system as recited in claim 1, wherein the history of movements is based on crowdsourced information.

8. A method comprising:

receiving, from a computing device, an identification of a trackable entity comprising a trackable mobile device carried by a person of interest, said device being trackable by a global positioning system;

receiving, from the computing device, an identification of each of a point of origin and a destination without receiving an identification of a path between the point of origin and destination;

accessing a database to identify, prior to movement of the trackable entity, one or more paths between the point of origin and the destination based on a history of movements of trackable entities comprising mobile devices carried by persons walking between the point of origin and the destination, wherein the trackable entities do not include the trackable entity;

receive global positioning system related data indicative of movement of the trackable entity;

generating an alert responsive to determining a movement of the trackable entity varies from the one or more paths;

identifying one or more intermediate locales along the identified one or more paths;

determining an expected duration of stay for each of the one or more intermediate locales based on the history of movements; and

adjusting an expected duration of stay for an intermediate locale based on one or more of an occupancy of the intermediate locale, weather, and traffic reports.

9. The method as recited in claim 8, wherein determining a movement of the trackable entity varies from the one or more paths comprises determining the trackable entity has been at an identified intermediate locale for a time exceeding an expected duration of stay.

10. The method as recited in claim 8, further comprising identifying the one or more paths and the expected durations of stay based on additional parameters comprising one or more of a particular time of day, a particular day of the week and a particular month.

11. The method as recited in claim 8, further comprising identifying the one or more paths based on additional parameters comprising interests and hobbies of the trackable entity.

12. The method as recited in claim 8, further comprising:

mapping the identified one or more paths to routes from a routes database; and

sending the generated alert to a destination device comprising one or more of a mobile device and a computer.

13. A non-transitory computer readable storage medium comprising program instructions, wherein the program instructions are executable by a processor to:

receive, from a computing device, an identification of a trackable entity comprising a trackable mobile device carried by a person of interest, said device being trackable by a global positioning system;

receive, from the computing device, an identification of each of a point of origin and a destination without receiving an identification of a path between the point of origin and destination;

access a database to identify, prior to movement of the trackable entity, one or more paths between the point of origin and the destination based on a history of movements of trackable entities comprising mobile devices carried by persons walking between the point of origin and the destination, wherein the trackable entities do not include the trackable entity;

receive global positioning system related data indicative of movement of the trackable entity;

generate an alert responsive to determining a movement of the trackable entity varies from the one or more paths;

identify one or more intermediate locales along the identified one or more paths;

determine an expected duration of stay for each of the one or more intermediate locales based on the history of movements; and

adjust an expected duration of stay for an intermediate locale based on one or more of an occupancy of the intermediate locale, weather, and traffic reports.

14. The non-transitory computer readable storage medium as recited in claim 13, wherein determining a movement of the trackable entity varies from the one or more paths comprises determining the trackable entity has been at an identified intermediate locale for a time exceeding an expected duration of stay.

15. The non-transitory computer readable storage medium as recited in claim 13, wherein the history of movements is based on crowdsourced information.
