<p>The invention is about an identification process of an individual or object, in a system comprising a control server and a management server of a database comprising N indexed data of N stored individuals, in which, to identify the individual or object, its datum is compared to each of the N data of the base. The process comprises steps during which: the control server acquires the datum of the individual or 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 lesser size, a set of p index of simplified data of the base, p being less than N, having the most similarities to the simplified datum of the individual or object to be identified, securely 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 scrambles the N reference data of the database, and transfers to the control server p scrambled data corresponding to the simplified data identified previously, from the p scrambled data the control server determines, by secure multi-party computation between each of the p scrambled data and the datum of the individual or object, the index or the indices of one or more scrambled data whereof the corresponding reference data have a rate of similarity to the datum of the individual or object, which exceeds a predetermined threshold.</p> |
