A METHOD AND A SYSTEM FOR DETECTING A POTENTIAL THREAT IN A SHOE WORN BY AN INDIVIDUAL

The invention concerns a method and a system (1) for detecting a threat in a shoe (21, 22) worn by an individual (2) accessing a restricted access area (50) through a security access point (51).The method comprises obtaining a first response provided by a first metal detector (11) by sensing a pair of shoes worn by the individual. The first response is compared with a signature signal representing a shoe comprising a threat or an object representing a threat so to indicate a critical pair of shoes. In such case, the method further comprises prompting the individual to place the critical pair of shoes at a predefined position to obtain a second response provided by the first or by a second metal detector (12, 13) by sensing one shoe of said critical pair of shoes. A potential threat is detected by comparing the second response with the signature signal.
