PROBLEM TO BE SOLVED: To provide a method for detecting and processing the possibility of illegal access by impersonating in the case of user authentication when a user logs in through the internet to a job application. SOLUTION: A user authentication application judges whether inputted user ID and password are coincident with a previously registered password or not and when it is judged that the password is not coincident with the registered password, it is judged whether the password is not coincident continuously more than prescribed times or not. When the password is not coincident more than prescribed times, while referring to a mail address registered concerning the relevant user, electronic mail reporting illegal access is transmitted to that mail address. |
