Contents transmitter apparatus, contents reciever apparatus and contents transmitting method
First Claim
1. A contents transmitter apparatus, comprising:
- authentication means for receiving an authentication request from a contents receiver apparatus and making determination upon authentication to said authentication request, when transmitting contents to said contents receiver apparatus, which is connected thereto through a network, and also for issuing an authentication request of itself to said contents receiver apparatus;
a timer means for transmitting an authentication request or a time authentication request to said contents receiver apparatus, and for measuring a time-period up to when receiving a response to said request; and
equipment-information management means for registering and managing equipment information about said contents receiver apparatus, wherein said equipment-information management means registers an address information and equipment information unique to the apparatus of said contents receiver apparatus, when a measurement result of said timer means does not exceed a predetermined value, and execute a measurement of time by means of said timer means for said contents receiver apparatus registered, depending upon necessity, thereby controlling said registration contents depending upon a result of said measurement.

Abstract
For achieving the protection of copyright, by suppressing illegal copy production thereof, in particular, when transmitting contents with using a wired or wireless LAN, as well as, for preventing the transmission of contents from deviating from a range of a personal use thereof, a contents transmitter apparatus and a contents receiver apparatus make an authentication, mutually, before transmitting contents therebetween. At the time when conducting this authentication, measurement is made upon a time-period up to arrival of a receipt confirmation responding to the transmission of an authentication request or a response to the authentication; then, only in the case when this value measured does not exceed a predetermined upper value, the transmission is conducted on the contents encrypted, and at the same time, address information and equipment information unique to the apparatus are registered, thereby conducting the transmission of encrypted contents, but without conducting the time-measurement thereon, when transmitting the contents, again. Also, while conducting the time-measurement periodically, dynamic management is made on the registration information, so that the contents thereof are suitable for the network structure at the present.

2. A contents transmitter apparatus, comprising:
-
a network communication processing means for conducting transmission of data through a network;
a transmission contents producing means for supplying contents, to be transmitted to a contents receiver apparatus, which is connected thereto through said network, to said network communication processing means;
an authentication means for receiving an authentication request from said contents receiver apparatus, so as to make determination upon an authentication to said authentication request, and also for issuing an authentication request of itself to said contents receiver apparatus;
an encryption means for producing key information upon basis of information, which is obtained through execution of an authentication processing in said authentication means, and for conducting encryption processing on the contents to be transmitted to said contents receiver apparatus with an aid of said key information;
a timer means for transmitting an authentication request or a time authentication request to said contents receiver apparatus, and for measuring a time-period up to when receiving a response to said request; and
an equipment-information management means for registering and managing equipment information about said contents receiver apparatus, wherein said equipment-information management means registers an address information of said contents receiver apparatus and equipment information unique to the apparatus thereof, which is memorized in advance when manufacturing the apparatus, when a measurement result does not exceed a predetermined value within said timer means, and execute a measurement of time by means of said timer means for said contents receiver apparatus registered, depending upon necessity, thereby controlling said registration contents depending upon a result of said measurement.

8. A contents receiver apparatus, comprising:
-
a network communication processing means for conducting transmission of data through a network;
a contents receiving and processing means for receiving contents received from a contents transmitter apparatus, which is connected through said network, from said network communication processing means;
an authentication means for issuing an authentication request to be transmitted to said contents transmitter apparatus, and for conducting determination upon authentication with respect to an authentication request from said contents transmitter apparatus; and
a decryption means for producing key information upon basis of information, which is obtained through execution of an authentication process within said authentication means, and for executing decryption process of the contents received from said contents transmitter apparatus with an aid of said key information, wherein a response is made responding to a time authentication request transmitted from said contents transmitter apparatus, and measurement is conducted on a time up to said response within said contents transmitter apparatus, thereby making a request to said contents transmitter apparatus, depending upon necessity thereof, of transmitting said time authentication request from said contents transmitter apparatus. - View Dependent Claims (9)

10. A contents transmitting method in a contents transmitter apparatus for transmitting contents to a contents receiver apparatus, which is connected through a network, comprising the following steps of:
-
a step for receiving an authentication request from said contents receiver apparatus to conduct determination upon authentication with respect to said authentication request, when transmitting the contents to said contents receiver apparatus, and also for issuing an authentication request of itself to said contents receiver apparatus;
a step for transmitting the authentication request or a time authentication request to said contents receiver apparatus, SO as to make measurement on a time up to when receiving a response to said request;
a step for registering and managing an equipment information of said contents receiver apparatus;
a step for registering an address information and an equipment information unique to an apparatus about said contents receiver apparatus, if a result of the measurement made in said step for measuring the time does not exceeds a predetermined value, when registering and managing said equipment information; and
a step for executing said step for measuring the time on said contents receiver apparatus registered, depending upon necessity, thereby controlling said registration contents depending upon a measured result of said measurement.
