Patent number: RE45696Abstract: An activity-area/time-frame weighting table indicates the likelihood of where a user is most likely to be in a certain time frame, and weighting (the number of points) is set depending on times frames, which are divided into weekdays and weekends. The activity pattern may be obtained through the user's application at the time of registration, or may be obtained by detecting the locations of the user for a predetermined period, such as for one week, using a GPS or PHS. For example, when a user is mostly likely to be on the route to the company from home in the time frame of commuting hours on a weekday, the weighting is set low. Based on an area and time frame in which a corresponding credit card or the like is used, the number of points is determined, and is then used to set an authentication level.Type: GrantFiled: November 17, 2011Date of Patent: September 29, 2015Assignee: SONY CORPORATIONInventors: Asami Yoshida, Takuya Iwamoto
