Abstract
A data sharing method using fingerprinted data objects for sharing data among untrusted network devices. Each peer device is adapted for storing a plurality of data objects, and a fingerprint generator is used to generate a fingerprint for each stored data object available for sharing or for recovery. The fingerprints are stored in a local data store, and a data manager running on one of the computer devices retrieves from another of the computer devices a copy of one of its data objects through the use of the associated fingerprints. The fingerprints include a hash value output from a strong hashing algorithm. The retrieving includes transmitting query messages with the fingerprints of the needed data objects to the networked, peer devices and then verifying the integrity of received data objects by generating a fingerprint of the received data objects that can be compared with the ones provided in the queries.
