摘要
The invention relates to a method for protecting against theft of a PIN number for (a) multi-application smart card(s) by applications which do not have any outside access. The inventive method consists in detecting operations for the verification of the PIN number by means of one or more applications devoid of access outside said card by counting the number of unsuccessful attempts irrespective of the application and by blocking the operation of said card when the number of subsequently attempted operations reaches a given threshold value.
