Abstract

Disclosed is a private information management apparatus in which the information of high practical utility for a user in person may be acquired more efficiently and with higher responsiveness than is possible with a technique of keyword retrieval over the network. To this end, a private information management apparatus 1 for acquiring and storing the experience information pertinent to an event experienced by a user, and the private information input by a user, includes, as a structure for authenticating a counterpart terminal, with which the user is to exchange the experience information and the private information, an authentication key generating unit 59 for generating an authentication key for authenticating the terminal for which the information is publicized, an encryption unit 60 for encrypting part of the experience information and the private information stored as the publicized information, based on the encryption key, and an authentication processing unit 61 for verifying whether or not the authentication key received from the external terminal is one from the designated terminal. In this manner, the user is able to publicize only the information the user may feel not disinclined to publicize to another user, based on the taste information stored from user to user.

Claims

1. A private information management apparatus comprising:

information acquisition means for acquiring experience information pertinent to an event experienced by a user;

private information adding means for adding to said acquired experience information the private information privately requested by the user;

storage means for putting said experience information and said private information into order and for storing the information so put into order in a manner which enables retrieval;

key generating means for generating an authentication key;

data encrypting means for encrypting part of the experience information and the private information stored in said storage means, based on an encryption key, wherein said encrypted information is publicized information; and

communication controlling means for transmitting the publicized information to an external device;

wherein said communication controlling means transmits the publicized information to a designated external device when an authentication key received from outside has been authenticated as being from said designated external device.

2. The private information management apparatus according to claim 1 further comprising:

operation inputting means for specifying information which is stored in said storage means and which is to be publicized, and an electronic device to which the information is to be publicized; and

wherein said data encrypting means encrypts the publicized information specified by said operation inputting means based on said encryption key.

3. The private information management apparatus according to claim 1 wherein said information acquisition means comprises speech data acquisition means for acquiring external speech data and includes speech recognition means for recognizing an utterance of a feature word from the external speech data;

and

wherein said storage means puts into order and stores a result of recognition by said speech recognition means and the private information in a manner which enables retrieval.

4. The private information management apparatus according to claim 1 wherein said information acquisition means comprises image data acquisition means for acquiring external image data and includes image recognition means for recognizing a feature image from the external image data;

and

wherein said storage means puts into order and stores a result of recognition by said image recognition means and the private information in a manner which enables retrieval.

5. The private information management apparatus according to claim 1 wherein said information acquisition means comprises sentence data acquisition means for acquiring sentence data and includes sentence recognition means for extracting feature words from the sentence data;

and

wherein said storage means puts into order and stores a result of recognition by said sentence recognition means and the private information in a manner which enables retrieval.

6. A private information management method comprising:

acquiring experience information pertinent to an event experienced by a user;

adding to said experience information private information privately required by the user;

putting said experience information and the private information retrievably into order for storage;

encrypting part of the experience information and the private information, based on an encryption key, wherein resulting encrypted information is publicized information;

encrypting said encryption key by an authentication key; and

transmitting the publicized information to an external device; and

transmitting the publicized information to a designated external device when an authentication key received from outside has been authenticated as being from said designated external device.
