<P>PROBLEM TO BE SOLVED: To provide a method for safely performing a transaction in a three-dimensional virtual space, and to solve problems of secrecy of the transaction, and phishing fraud or the like in the three-dimensional virtual space. <P>SOLUTION: A copy space of an original space of a facility on the three-dimensional virtual space is created. Because only an avatar permitted with entrance into the copy space can enter the copy space, the transaction can be safely performed between the facility and the user avatar. <P>COPYRIGHT: (C)2009,JPO&INPIT |
