Abstract

An information service system works to record or print out, at a fee, information contents downloaded from Web servers, information received from facsimiles and information carried on portable storage mediums. The system includes a recording part which records, duplicates and prints out the image of digitized information, an information accumulating part which accumulates information by making relation with users, a user authenticating part which receives user authentication information and authenticates the legitimacy of the user, a fee calculating part which calculates the fee for information recording, a payment reception part which receives the payment of fee by the user, and a management part which manages the charging data and payment data. The recording part records the supplied information only after authentication of user legitimacy and payment of fee by the user. Based on the authentication of user legitimacy and the management of payment of individual users, the recording part can be used commonly among multiple users and the charged information recording service can be run easily.

Claims

1. An information distributing system, comprising:

a content distribution device; and

a user terminal,

wherein;

the content information distribution device issues a first ticket corresponding to a first content and a second ticket corresponding to a second content, and distributes the first ticket, the second ticket, an encrypted first content generated by encryption of the first content, and an encrypted second content generated by encryption of the second content, the first ticket including first decryption key information being customized to a first user and to be used for decrypting the encrypted first content, the second ticket including second decryption key information being made effective for all users including the first user and to be used for decrypting the encrypted second content, and

the user terminal includes;

a receiving section that receives the first ticket, the second ticket, the encrypted first content, and the encrypted second content from the content distribution device through a network;

a judging section that judges whether the encrypted first content is decrypted by using unique user information and the first decryption key information, the unique user information being acquired from a token provided to the user terminal by a user; and

a controller that controls (a) a display device to display first information, which represents the first content, on a screen, when the judging section judges that the encrypted first content is decrypted by using unique user information and the first decryption key information, so that the first user can designate the first information on the screen for outputting the first content, (b) the display device to not display the first information on the screen, when the judging section judges that the encrypted first content is not decrypted by using unique user information and the first decryption key information, and (c) the display device to display second information, which represents the second content, on the screen so that all the users can designate the second information on the screen for outputting the second content.

2. The information distributing system according to claim 1, wherein the token is an IC card, and the user terminal further comprises acquiring section that acquires the unique user information from the IC card.

3. The information distributing system according to claim 1, further comprising:

a decryption section that decrypts the encrypted first content; and

an output control section that controls the first content decrypted by the decryption section to be output to a printer when the judging section judges that the encrypted first content is decrypted by using unique user information and the first decryption key information.

4. The information distributing system according to claim 1, wherein the first information and the second information includes at least one of an icon and an abstract that represents the first content and second content.

5. A user terminal, comprising:

a receiving section that receives, from a content information distribution device through a network, a first ticket corresponding to a first content, a second ticket corresponding to a second content, an encrypted first content generated by encryption to the first content, and an encrypted second content generated by encryption to the second content, the first ticket including first decryption key information being customized to a first user and to be used for decrypting the encrypted first content, the second ticket including second decryption key information being made effective for all users including the first user and to be used for decrypting the encrypted second content;

a judging section that judges whether the encrypted first content is decrypted by using unique user information and the first decryption key information, the unique user information being acquired from a token provided to the user terminal by a user; and

a controller that controls (a) a display device to display first information, which represents the first content, on a screen, when the judging section judges that the encrypted first content is decrypted by using unique user information and the first decryption key information, so that the first user can designate the first information on the screen for outputting the first content, (b) the display device to not display the first information on the screen, when the judging section judges that the encrypted first content is not decrypted by using unique user information and the first decryption key information, and (c) the display device to display second information, which represents the second content, on the screen so that all the users can designate the second information on the screen for outputting the second content.

6. The information distributing system according to claim 5, wherein the token is an IC card, and the user terminal further comprises acquiring section that acquires the unique user information from the IC card.

7. The information distributing system according to claim 5, further comprising:

a decryption section that decrypts the encrypted first content; and

an output control section that controls the first content decrypted by the decryption section to be output to a printer when the judging section judges that the encrypted first content is decrypted by using unique user information and the first decryption key information.

8. The information distributing system according to claim 5, wherein the first information and the second information includes at least one of an icon and an abstract that represents the first content and second content.
