Abstract

La présente invention concerne un terminal mobile (200) qui affiche un champ d'entrée de résultat associé à un identifiant de site et produit des données de travail comprenant l'identifiant de site lors de la sélection du champ d'entrée de résultat. Un dispositif d'évaluation de travail (300) acquiert, à partir d'une base de données de site (111), des données de site associées à l'identifiant de site compris dans les données de travail. Le dispositif d'évaluation de travail calcule des informations d'emplacement de travail indiquant l'emplacement du terminal mobile à un moment de travail. Le dispositif d'évaluation de travail détermine ensuite si les informations d'emplacement de travail sont valides sur la base des informations d'emplacement de référence comprises dans les données de site acquises.
