<p>The invention relates to a method of identifying an individual or an object, in a system comprising a control server and a server for managing a database comprising N indexed data of N catalogued individuals, in which, to identify the individual or the object, its datum is compared with each of the N data of the base. The method comprises steps in the course of which: the control server acquires the datum of the individual or the object to be identified, - the reference data of the base and the datum of the individual or object to be identified are converted into simplified data of smaller size, - a set of p indices of simplified data of the base exhibiting the greatest similarities with the simplified datum of the individual or object to be identified is determined, in a secure manner between each of the N simplified data of the database and the simplified datum of the individual or object to be identified, - the management server shuffles the N reference data of the database, and transfers to the control server p shuffled data corresponding to the simplified data identified previously, - on the basis of the p shuffled data, the control server determines, by secure multipartite calculation between each of the p shuffled data and the datum of the individual or object, the indices of the shuffled data whose corresponding reference data exhibit a degree of similarity with the datum of the individual or object which exceeds a predetermined threshold.</p> |
