Abstract (in Japanese) (See Japanese page) 
(in English) Many web services with a login function using pair of ID and password have the password recovery function in case the user forgets his/her password. The password recovery function reveals a part of the email address which is to send the URL to recover the corresponding password. However, if the user has registered for multiple web services using the same ID, the attacker can easily guess the email address by aggregating the disclosed parts. In this paper, we discuss possible attack that reconstructs the email address using the password recovery function of multiple web services and evaluate its effectiveness. We also propose countermeasures against the attack that reconstructs email addresses.
