Abstract:
1. A method of operating a system for recommendation of a content item, the system including at least a portable first device, a portable second device, and a third device, comprising: determining, by the first device, first identifiers descriptive for first content items stored on the first device, the first device assigned to a first user, each first identifier being fingerprint data extracted from audio information contained in one of the first content items; determining, by the second device, second identifiers descriptive for second content items stored on the second device, the second device assigned to a second user, each second identifier being fingerprint data extracted from audio information contained in one of the second content items; sending the second identifiers from the second device to said first device; determining, by said first device, measures for at least a part of the first content items, wherein each measure is associated with a respective content item, wherein the measure is a value that is higher for the respective content item stored in both the first device and the second device than for the respective content item stored in a single one of the first and the second devices; sending the measures from the first device to said third device; determining or updating, on said third device, an item-to-item matrix based on said measures, wherein said first, second, and third devices are physically separate devices, wherein to each content item the item-to-item matrix assigns a plurality of second measures, and wherein each second measure is assigned to one of other content items and is a value that is high for content items stored in both the first device and the second device, medium for content items stored in a single one of the first and the second devices, and low for content items stored in neither the first nor the second device; and determining, by a processor of the third device, a recommendation for the first user, the second user, or another user based on said plurality of second measures assigned to each content item identified by data sent to the third device.
