A method and a system for detecting a potential threat in a shoe worn by an individual

A method for detecting a threat in a shoe worn by an individual accessing a restricted access area through a security access point, the method comprising steps of:

• obtaining a first response provided by a first metal detector by sensing a pair of shoes worn by the individual standing on or walking through the security access point;
• detecting a critical pair of shoes by comparing said first response with a predefined signature signal representing a shoe comprising a threat or an object representing a threat;
• and in response of a comparison indicating a critical pair of shoes:
• prompting the individual to place the critical pair of shoes at a predefined position with respect to said first metal detector or with respect to a second metal detector;
• obtaining a second response provided by said first metal detector or by said second metal detector sensing one shoe of said critical pair of shoes at said predefined position;
• and
• detecting a potential threat by comparing the second response with the same predefined signature signal.
