Device update transmission using a filter structure

A server comprising:

• a processor;
• and
• a non-transitory computer readable medium comprising computer-executable instructions that cause the processor to perform operations comprising:
• detecting a campaign initiation request specifying a plurality of computerized devices to be updated with a device update for a campaign;
• generating a filter data structure comprising a plurality of hash values, wherein each hash value is based on data associated with one of the computerized devices in the plurality of computerized devices;
• providing the filter data structure from the server to a second server;
• receiving a request for the device update from a computerized device that has been preliminarily determined to be in the campaign based on the filter data structure;
• confirming that the computerized device is a member of the campaign based on the data corresponding to the plurality of computerized devices to be updated;
• and
• providing the device update associated with the request to at least one of a second server or the computerized device;
• wherein,
• if the computerized device is not confirmed as a member of the campaign, providing to at least one of the second server and the computerized device, an indication that there is no device update for the computerized device.

A method for providing campaign based device updates, the method comprising:

• detecting, by a first server, a campaign initiation request specifying a plurality of computerized devices to be updated with a device update for a campaign;
• generating a filter data structure comprising a plurality of hash values, wherein each hash value is based on data associated with one of the computerized devices in the plurality of computerized devices;
• providing the filter data structure, to a second server in communication with at least one of the computerized devices;
• receiving, by the second server a request for the device update from a computerized device that has been preliminarily determined to be in the campaign based on the filter data structure;
• determining, by the second server, whether a requesting computerized device is in the update campaign based on the filter data structure and identifying information identifying the requesting computerized device;
• in response to the determining, confirming, by the first server, that the computerized device is a member of the campaign based on the data corresponding to the plurality of computerized devices to be updated;
• and
• in response to the confirming, providing the device update to the requesting computerized device;
• wherein,
• if the computerized device is not confirmed as a member of the campaign, providing to at least one of the second server and the computerized device, an indication that there is no device update for the computerized device.
