Abstract
A system and method according to the principles of the invention identifies mobile phone aliases. The system processes mobile location data and call event data to generate mobility profiles. The profiles indicate a mobile's geographic zone history over a specified time. To produce a mobility profile, the system aggregates location data into zones and associates the zones with times of day, week or month. Particular zones for different mobiles can be compared according to weighting algorithms to provide data indicating whether the mobiles belong to the same user.
Claims16
A method for determining that a first mobile is an alias of a second mobile comprising:
- determining a first mobility profile for the first mobile and a second mobility profile for the second mobile;
- wherein the determining the first mobility profile includes:
- defining a profile time interval having time slots;
- collecting location data for the first mobile over the profile time interval;
- aggregating selections of the collected location data into corresponding zones;
- and
- for the profile time interval, relating ones of the zones to the time slots;
- comparing the first mobility profile to the second mobility profile;
- and
- calculating a result of the comparing step wherein exceeding a threshold result indicates a relative likelihood that the first mobile is an alias of the second mobile.
A method for determining that a first mobile is an alias of a second mobile comprising:
- determining a first mobility profile for the first mobile and a second mobility profile for the second mobile;
- comparing the first mobility profile to the second mobility profile;
- calculating a result of the comparing step wherein exceeding a threshold result indicates a relative likelihood that the first mobile is an alias of the second mobile;
- for a period, establishing a plurality of geo-fences around the first mobile;
- identifying candidate mobiles from the set of mobiles located within the plurality of geo-fences during the period, including the step of identifying mobiles other than the first mobile that appear within the plurality of geo-fences more than a threshold number of times;
- designating one or more second mobiles from the candidate mobiles.
A system comprising:
- a processor for:
- generating a first mobility profile for a first mobile and a second mobility profile for a second mobile, wherein the first mobility profile and the second mobility profile include data indicating corresponding zones comprising an aggregation of locations and times for the first mobile and the second mobile, respectively;
- determining whether the first mobility profiles matches the second mobility profile within an acceptable range;
- and
- inferring that a user of the first mobile is substantially similar to a user of the second mobile based on whether the first mobility profile matches the second mobility profile.
