Methods and systems for persistent cross-application mobile device identification

A system for persistently identifying a mobile device across applications, the system comprising:

• a memory which comprises:
• a first sandbox associated with a first application;
• a second sandbox associated with a second application;
• and
• a persistent shared storage configured to store a universal device identifier;
• and
• a processor programmed to:
• execute the first application in the first sandbox, the first application restricted from accessing the second sandbox;
• execute the second application in the second sandbox, wherein the second application is restricted from accessing the first sandbox;
• receive a first request from the first application and a second request from the second application to access information associated with the mobile device, wherein the first request and the second request comprises the universal device identifier;
• identify data associated with usage patterns of the mobile device across the first application and the second application;
• link the data associated with the usage patterns with the universal device identifier;
• store the data associated with the usage patterns in the persistent shared storage;
• in response to the first request and the second request, access the persistent shared storage and return a data packet comprising the data associated with the usage patterns of the mobile device to the first application and the second application.

A computer implemented method for persistently identifying a mobile device across applications, the computer-implemented method comprising:

• executing the first application in the first sandbox, the first application restricted from accessing the second sandbox;
• executing the second application in the second sandbox, the second application restricted from accessing the first sandbox;
• receiving a first request from the first application and a second request from the second application to access information associated with the mobile device, the first request and the second request comprising the universal device identifier;
• identifying data associated with usage patterns of the mobile device across the first application and the second application;
• linking the data associated with the usage patterns with the universal device identifier;
• storing the data associated with the usage patterns in the persistent shared storage;
• in response to the first request and the second request, accessing the persistent shared storage and returning a data packet comprising the data associated with the usage patterns of the mobile device to the first application and the second application.
