L'invention porte sur un terminal d'information à panneau tactile qui comprend : une unité d'acquisition qui acquiert des informations d'opération sur le panneau tactile concernant une pluralité d'opérations de saisie qui sont réalisées séquentiellement ; une unité de détermination qui, sur la base des informations d'opération, détermine si chacune des opérations de saisie correspond à une opération de saisie prescrite quelconque ; une unité d'authentification qui détermine si un motif de saisie formé par la pluralité d'opérations de saisie correspond à un motif d'authentification formé par une pluralité d'opérations de saisie prescrites en série chronologique ; et une unité de commande qui, lorsqu'il est déterminé que le motif de saisie correspond au motif d'authentification, réalise un déverrouillage du terminal d'information. Les opérations de saisie prescrites ne sont pas limitées en termes de positions d'opération absolues sur le panneau tactile. L'unité de détermination n'utilise pas, dans la détermination, les positions absolues sur le panneau tactile où les opérations de saisie sont effectuées.
