## Abstract

An information processing apparatus and method make it possible for persons at remote places to enjoy simultaneous playback of contents while promoting copyright and privacy protection. A copyright authentication section decides, based on a copyright restriction added to a content and license information stored in a license storage section, whether utilization of the content is permitted. An accounting processing section, in response to a result of the decision, cooperates with an authentication sever to perform accounting. A privacy authentication section decides, based on the privacy restriction and privacy information, whether utilization of the content is permitted. A permission request processing section, in response to a result of the decision, performs a communication process with a communication apparatus, which has a privacy management right in the content.

## Claims

### Claim 1

An information processing apparatus, comprising:
a communication circuit configured to communicate with a plurality of information processing apparatuses via a network;
an authentication circuit configured to determine, based on personal restriction information including a privacy level of the information processing apparatus relative to a sharing group included in content data in addition to copyright restriction information, whether use of the content data is permitted;
a sharing decision circuit configured to determine whether utilization of the content data is permitted based on at least a comparison between a maximum number of sharing terminals information included in the content data and a number of different information processing apparatuses performing synchronous playback with the information processing apparatus; and
a synchronous playback circuit configured to play back the content data in synchronism with the different information processing apparatuses, when use of the content data is permitted based on the personal restriction information and the comparison of the maximum number of sharing terminals information and the number of different information processing apparatuses.

### Claim 2 (depends on 1)

The information processing apparatus according to claim 1, further comprising:
a notification circuit configured to control notification of use restriction when the circuitry determines at least one of the authentication circuit and the sharing decision circuit determines that use of the content data is not permitted.

### Claim 3 (depends on 1)

The information processing apparatus according to claim 1, further comprising:
a recording control circuit configured to control recording of the content data based on the copyright restriction information and the personal information restriction information.

### Claim 4 (depends on 1)

The information processing apparatus according to claim 1, further comprising:
a reception circuit configured to receive sound and images from the other information processing apparatuses; and
a synthesis circuit configured to synthesize a sound and an image of the content data played back in synchronism by said playback circuit and the sound and the image of the user received by said reception section.

### Claim 5

An information processing method, comprising:
communicating, via a communication device, with different information processing apparatuses via a network;
determining, in an authentication circuit and based on personal restriction information including a privacy level of the information processing apparatus relative to a sharing group which is included in the content data, whether use of the content data is permitted;
determining, in a sharing determination circuit, whether use of the content data is permitted based on a comparison between a maximum number of sharing terminals information and a number of the different information processing apparatuses performing synchronous playback with the information processing apparatus; and
synchronously playing back the content data with the different information processing apparatuses, when use of the content data is permitted based on the personal restriction information and the comparison of the maximum number of sharing terminals information and the number of different information processing apparatuses.

### Claim 6

A non-transitory computer readable storage medium storing computer-readable instructions thereon that, when executed by a processor of an information processing apparatus, causes the processor to perform a process comprising:
communicating with different information processing apparatuses via through a network;
determining based on personal restriction information including a privacy level of the information processing apparatus relative to a sharing group which is included in the content data, whether use of the content data is permitted;
determining whether use of the content data is permitted based on a comparison between a maximum number of sharing terminals information and a number of the different information processing apparatuses performing synchronous playback with the information processing apparatus; and
