Predicting lost devices using normal usage patterns

A computer program product comprising a computer readable storage medium and program instructions stored on the computer readable storage medium, the program instructions comprising:

• program instructions to identify a main device associated with a user, at least a first known environment device at a first checkpoint location, and a second known environment device at a second checkpoint location, wherein the at least first known environment device and the second known environment device are capable of communicating with the main device;
• program instructions to receive location and time information from the at least first known environment device after recognizing that the main device is located within the first checkpoint location and the second known environment device after recognizing that the main device is located within the second checkpoint location;
• program instructions to derive a common usage pattern of the main device, based on the location and time information, wherein the common usage pattern projects an expected location of the main device at a known time;
• program instructions to determine whether the main device deviates from the derived common usage pattern by determining whether the main device is located at the expected location at the known time;
• and
• in response to determining the main device deviates from the common usage pattern, program instructions to send an alert for the user, wherein the alert is sent to the at least first known environment device when the common usage pattern projects the expected location of the main device should correspond with the first checkpoint location and the second known environment device when the common usage pattern projects the expected location of the main device should correspond with the second checkpoint location.

A computer system comprising:

• one or more computer processors;
• one or more computer readable storage media;
• program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
• program instructions to identify a main device associated with a user, at least a first known environment device at a first checkpoint location, and a second known environment device at a second checkpoint location, wherein the at least first known environment device and the second known environment device are capable of communicating with the main device;
• program instructions to receive location and time information from the at least first known environment device after recognizing that the main device is located within the first checkpoint location and the second known environment device after recognizing that the main device is located within the second checkpoint location;
• program instructions to derive a common usage pattern of the main device, based on the location and time information, wherein the common usage pattern projects an expected location of the main device at a known time;
• program instructions to determine whether the main device deviates from the derived common usage pattern by determining whether the main device is located at the expected location at the known time;
• and
• in response to determining the main device deviates from the common usage pattern, program instructions to send an alert for the user, wherein the alert is sent to the at least first known environment device when the common usage pattern projects the expected location of the main device should correspond with the first checkpoint location and the second known environment device when the common usage pattern projects the expected location of the main device should correspond with the second checkpoint location.
