Embodiment 1

[0069] Next, the structure and operation of the presence server in this embodiment and the network for realizing the service using the presence server will be described.

[0070] FIG. 1 schematically shows a functional block diagram of the presence server in this embodiment. The functional block diagram in FIG. 1 is a diagram showing a logical functional structure realized in software, and each functional block diagram may be configured by hardware.

[0071] The functional blocks shown in FIG. 1 shown in FIG. 2 are any implemented in hardware. The operations of various functional blocks shown in FIG. 1 are stored in the program storage unit 26 of the memory 22 shown in FIG. 2 , and the CPU 21 reads out and executes the operation steps during operation. When each functional block operates, the necessary allowable setting values ​​are stored in the memory 22, and the CPU 21 reads and writes necessary information by reading the registration table stored in the memory 22.

Embodiment 2

[0127] Fig. 17 shows a second embodiment of a business model employing a presence server. UserA indicated by 224 in FIG. 17 often uses ○× stores for daily shopping. The product purchase history of User A is accumulated in the ○× store purchase history accumulation server 221 . In addition, UserA has registered user ID 272 shown in FIG. 21, interest 273 as user incidental information, annual income 274, terminal ID 276, On / Off 277 as terminal incidental information, and position 278 shown in FIG. The store information delivery server 222 is a user who receives the service. The overall operation will not be described, but the UserA 224 registers its own user information and permission settings for the store information delivery server 222 in the presence server 1 . Also, a service provision request is made to the store information distribution server 222 and the service is received via the information distribution server 223 .

[0128] Figure 10 is the sequence of operations....

Embodiment 3

[0134] FIG. 22 shows Embodiment 3 of a business model using a presence server. UserA301 is registered on the presence server 1 with user ID312 shown in FIG. 25 , interest 313 as user incidental information, annual income 314 , ID315 of terminal 1 owned by UserA, On / Off 316 and location 317 as incidental information of terminal 1 . In addition, UserB 302 is a user who makes a reservation for an information update notification of UserA and grasps the current status of UserA. Fig. 24 is an operation sequence diagram of this embodiment. The specific operation of this embodiment will be described below using FIG. 24 . First, in step 321 , UserA logs interest 313 into presence server 1 . Since it is assumed that the presence server 1 saves the interest 313 in the database server A303-1, it is registered in the database server A303-1 in step 322.

[0135]Then UserA registers the location 316 attached to the terminal 1 to the presence server 1 in step 323 . Since it is set that t...

Abstract

The invention relates to a server (1) having the function of categorizing permission setting values indicating whether object information items of various attribute of a registered user are disclosable to other persons or not depending on a level of the disclosability, and managing the permission setting values hierarchically.

Description

technical field [0001] The present invention relates to a setting method of information disclosure. Background technique [0002] With the development of communication technology and network technology, the ubiquitous network society that communicates anytime and anywhere is coming. It can be said that in communication in a ubiquitous society, each user can register personal information of himself and others into a database and receive various services. [0003] One of the ways to manage privacy protection on databases today is to adopt the permissive system that Unix systems are using. This is a directory or file on a file system with a directory structure, which is divided into three types of access units: owner, group, and others. For each access unit, Read (read), Write (write), Execute (Execution) The way to set whether access is allowed in the three operation aspects. Allowance setting is usually performed by the administrator from the viewpoint of the security of t...
