Patent claim: A computerimplemented system implementing a collaborative authentication platform comprising a network connection for digital communications an authentication database interface arranged for connection over a network to query an authentication database storing digital fingerprints from one or more physical objects the digital fingerprints from image data that is derived for each object from the object itself and does not rely upon reading or recognizing information from labels tags integrated materials unique identification characters codes or other items that were added to the object for the purpose of identification a communication module for communication over a network to client devices a collaboration module configured to generate and send a request message via the communication module to a plurality of client devices the request message including an identifier of an object of interest and an invitation to a collaborator to capture image data of a target object associated with the identifier the collaboration module further configured to receive reply messages via the communication module from the client devices and for each received reply messageassociate the reply message to a corresponding request message so as to ensure that the captured image data is properly associated with the object of interest extract the captured image data from the reply message cause the authentication database interface to query the authentication database based on the identifier and the captured image data of the target object to obtain a matching result in a case that the matching result indicates that a matching record was found in the database cause the authentication database interface to update the matching record to include the captured image data and associated metadata the associated metadata including an identifier of the collaborator that submitted the reply message so as to enrich the authentication dataset with data provided by one or more collaborators in the reply messages.

Related passage: The invention proposes a novel protocol for secure identification and authentication of various items using unclonable features.The protocol acts in two modes identity verification and authenticity verification.Both modes are implemented based on unique unclonable features of item surfaces that either have a natural origin or artificially produced by humans by printing laser engraving coating gluing sticking painting stamping embedding light exposition heating current passing potential charging or any other forms of radiation or physical impact etc.Due to the infeasibility of their copying and reproduction these features can be used as secure item identificationauthentication codes as well as inputs for generation of such codes or secure keys extracted from the natural randomness.The second distinctive feature of the invention is the mobile platform in sense that item identificationauthentication is performed based on typical mobile phones Pocket PCs Smartphones PDAs Palms etc.hereafter portable devices although use of classical scanners cameras or microscopes in the invented protocol is as well possible.Independently of the way the secure code is produced natural or artificial on the object surface it is acquired by camera of a portable device and is communicated to a secure server by means of MMS email Bluetooth Internet or any other possible communication means.Depending on the way secure codes are stored on the server microstructures are used as these codes or are considered as inputs for their generation a comparison of the acquired data with the content of a secure database is performed.The database is organized in two different ways depending on the identification or authentication application.The final decision about the match allows to confirmreject the item authenticity or to establish its identity.
