Abstract:
1. A method of tracking, in a postal sorting system having a first network of sorting machines and a second network of sorting machines, a mailpiece intended to be delivered, said method comprising the steps of: generating a first unique mailpiece identifier and a first dated tracking data from said mailpiece when passing through the first network of sorting machines by a first unique identification protocol of said postal sorting system, generating a second unique mailpiece identifier and a second dated tracking data from said mailpiece when passing through a second network of sorting machines by a second unique identification protocol of said postal sorting system, associating in a data-processing unit said first unique mailpiece identifier and said first dated tracking data with a first image of said mailpiece when passing through the first network and associating in said data-processing unit said second unique mailpiece identifier and said second dated tracking data with a second image of said mailpiece when passing through the second network, detecting in said data-processing unit a graphical matching between said first image and said second image of said mailpiece and in response thereto: associating in said data-processing unit the first and second unique mailpiece identifiers of said mailpiece, and retrieving in said data-processing unit said first dated tracking data and said second dated tracking data corresponding to said associated first and second unique mailpiece identifiers and based on said first dated tracking data and said second dated tracking data, establishing a time characteristic of the dated tracking data of said mailpiece throughout its journey through the first and second networks of said postal sorting system so as to determine said tracking of said mailpiece.
