<P>PROBLEM TO BE SOLVED: To provide a network synchronization system or the like for preventing data other than a synchronization object from being updated (deleted, for instance) in situations not intended by a user by synchronization processing, by confirming the data other than the synchronization object which is linked with synchronization object data and managed. <P>SOLUTION: An information processor of the network synchronization system related to this invention includes: user information storage means for storing user information; user data storage means for storing user data present corresponding to each user information; synchronization shared storage means for duplicating and storing the user information and sharing the duplicated user information of the present device with another device different from the present device; and synchronization control means for updating the user information of the present device to the latest user information in synchronism with the other device and updating the user information of the user information storage means on the basis of the latest user information. When deleting the user information of the present device, the synchronization control means executes prescribed processing when the user data corresponding to the user information of the deletion object is stored. <P>COPYRIGHT: (C)2012,JPO&INPIT |
