Abstract

Embodiments of the present invention provide a method, system and computer program product for limiting client side data storage based upon client geolocation. In an embodiment of the invention, a method for the differentiated treatment of data at rest in a mobile device includes receiving in a cache manager a request to cache data in a cache of a mobile device. Also, a geolocation for the mobile device is retrieved contemporaneous with the receipt of the request. Thereafter, it is determined from the geolocation whether or not the mobile device is present within a restricted geographic zone. Finally, in response to determining that the mobile device is present within a restricted geographic zone, the cache manager is directed to cache the data in a cache in the mobile device. But, otherwise the cache manager is directed to cache the data in a cache disposed in the computer communications network.

First claim

We claim:

1. A method for differentiated treatment of data at rest in a mobile device, the method comprising:
establishing a communicative link between the mobile device and a remotely disposed cache manager service;
receiving from the mobile device an indication of receipt of data in static memory of the mobile device from over a computer communications network;
retrieving from the mobile device in the remotely disposed cache manager service, a geolocation for the mobile device contemporaneous with the receipt of the data;
determining from the geolocation whether or not the mobile device is present within a restricted geographic zone in which caching of data outside of the mobile device is prohibited; and,
responsive to determining that the mobile device is present within a restricted geographic zone, the remotely disposed cache manager service directing the caching of the received data in a cache in static memory of the mobile device instead of caching the received data in another cache disposed externally to the mobile device in memory of a server that is separate from the mobile device and separate from but communicatively linked to the remotely disposed cache manager service in the computer communications network, but otherwise caching the received data in the cache that is disposed externally to the mobile device.

2. The method of claim 1 , further comprising:
receiving from the mobile device an indication of a request to retrieve data in the mobile device;
retrieving from the mobile device in the remotely disposed cache manager service, a geolocation for the mobile device contemporaneous with the receipt of the request;
determining from the geolocation whether or not the mobile device is present within the restricted geographic zone; and,
responsive to determining that the mobile device is present within the restricted geographic zone, directing the mobile device to perform retrieving of the requested data from the cache in the mobile device, but otherwise directing the mobile device to perform requesting retrieval of the requested data from the cache that is disposed externally to the mobile device.

3. A data processing system configured for limiting client side data storage based upon client geolocation, the data processing system comprising:
a mobile computing device comprising both static and dynamic memory and at least one processor;
a cache disposed in the static memory of the mobile computing device and another cache disposed in memory of a server that is separate from the mobile computing device; and,
a cache manager remotely disposed over a computer communications network from both the mobile computing device and the server, but coupled to both of the caches, the cache manager comprising program code enabled upon execution to receive a request to cache data, to retrieve a geolocation for the mobile device contemporaneous with the receipt of the request, to determine from the geolocation whether or not the mobile device is present within a restricted geographic zone in which caching of data outside of the mobile device is prohibited, and to respond to a determination that the mobile device is present within a restricted geographic zone, by caching of the data in the cache disposed in the static memory of the mobile device instead of caching the received data in a cache disposed externally to the mobile device, but otherwise by caching the data in the remotely disposed cache externally to the mobile device.

4. A computer program product for differentiated treatment of data at rest in a mobile device, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a device to cause the device to perform a method comprising:
establishing a communicative link between the mobile device and a remotely disposed cache manager service;
receiving from the mobile device an indication of receipt of data in static memory of the mobile device from over a computer communications network;
retrieving from the mobile device in the remotely disposed cache manager service, a geolocation for the mobile device contemporaneous with the receipt of the data;
determining from the geolocation whether or not the mobile device is present within a restricted geographic zone in which caching of data outside of the mobile device is prohibited; and
responsive to determining that the mobile device is present within a restricted geographic zone, the remotely disposed cache manager service directing the caching of the received data in a cache in static memory of the mobile device instead of caching the received data in another cache disposed externally to the mobile device in memory of a server that is separate from the mobile device and separate from but communicatively linked to the remotely disposed cache manager service in the computer communications network, but otherwise caching the received data in the cache that is disposed externally to the mobile device.

5. The computer program product of claim 4 , wherein the method further comprises:
receiving from the mobile device an indication of a request to retrieve data in the mobile device;
retrieving from the mobile device in the remotely disposed cache manager service, a geolocation for the mobile device contemporaneous with the receipt of the request;
determining from the geolocation whether or not the mobile device is present within the restricted geographic zone; and,
responsive to determining that the mobile device is present within the restricted geographic zone, directing the mobile device to perform retrieving of the requested data from the cache in the mobile device, but otherwise directing the mobile device to perform requesting retrieval of the requested data from the cache that is disposed externally to the mobile device.
