Abstract

The present invention relates to a method of extending the validity period of a fixed-term paid content, a fixed-term paid content providing system and a terminal device performing the same.

According to the present invention, the system for providing the fixed-term paid content whose usage rights are limited within the set validity period checks whether the valid period of the fixed-term paid content provided for each subscriber expires. When the paid content is expired, the authentication period is automatically generated and transmitted to the terminal device of the subscriber. That is, it automatically generates and transmits authentication information that extends the validity period without requesting to extend the validity period from the terminal device.

Accordingly, since the fixed-term paid content providing system automatically transmits the authentication information for extending the validity period to the subscriber's terminal, the terminal needs to access the server every time to extend the validity period of the paid content, and the user pays for the paid content. You do not need to be aware of the validity period for paid content unless you terminate the service.

Description

Method for extending a term of validity of a charged contents limitied the use within a certain period of time, system and terminal unit

The present invention relates to a method of extending the validity period of a fixed-term paid content, a fixed-term paid content providing system and a terminal device performing the same. More specifically, the present invention relates to a method of extending a validity period when a validity period of downloaded paid content is expired, a system for providing a paid content system and a terminal device for performing the same.

Digital Rights Management (hereinafter referred to as DRM) controls DRM so that the content provider uses the contents delivered to the user as much as the rights granted to the user. That is, the content provider issues together the content protected using a specific encryption key and the necessary usage rights for using the protected content so that the content can be protected from a user who does not have access.

The user receives the protected content and the right to use and interprets the permission contained in the right to control the use of the protected content. For example, in the case of a fixed-term paid content for which a valid period is set, reproduction of the content is permitted within the valid period, and reproduction is not allowed if the period is exceeded. Therefore, the user can use the content within a predetermined period of time, and after the expiration date, the content is newly purchased at a regular price.

However, in the case of paid content used in a terminal, the use of paid content is extended unless the user cancels it in the form of a mobile communication additional service. In other words, the monthly service fee is paid in addition to the mobile communication fee.

In addition, the paid content is set in a prepaid concept, and the validity period is set only for the period in which the fee is paid in advance. For example, if a user subscribes to a paid content service in January, the validity period of the paid content downloaded on January 5 is set to January 5 to February 5.

Conventionally, when the user expires of the downloaded paid content, the expired paid content must be deleted from the terminal, and the paid content with the extended validity must be downloaded again from the personal computer connected through the sync module. do.

Or, access the paid content server via the wireless Internet and download a file containing the authentication key to extend the validity period from the paid content server.

The term-based paid content using service provided by the term-based paying content providing system 400 is renewed every month unless the subscriber cancels the service. In addition, payment of the service usage fee is made every month in the form of an additional service fee from the subscriber's mobile communication fee.

The fixed-term paid content providing system 400 generates authentication information for the corresponding content and transmits it to the terminal device 100 when the valid period of the paid content of the subscriber expires. In this case, the transmission is unidirectionally transmitted by the system itself without the request of the terminal device 100.

Here, the fixed-term paid content is a content in a digital rights management (DRM) format, in which usage is limited as much as a given right, and typically, a paid sound source file may be used as an example.

The fixed-term paid content is protected by a specific encryption key, and in detail, separated into a header containing the content content and information about the content content. The header includes paid content information, information of a content provider, usage information, and the like, and the usage information includes valid period information.

In addition, the authentication information is a file that serves as a key that can decrypt such fixed-term paid content, it is generated in the form of electronic signature. The authentication information specifically includes valid period information in addition to user information, device information, and the like for using the fixed-term paid content.

That is, the fixed-term paid content providing system 400 manages whether the paid content for each subscriber expires automatically and automatically sends authentication information for extending the validity period, so that the subscriber can transmit the terminal device 100 to the wired network or wirelessly. There is no need to access the paid content providing system 400 through a network and request the download of the fixed-term paid content or the authentication information for extending the validity period.

The terminal device 100 uses the authentication information received from the fixed-term pay content providing system 400 to update the validity period of the fixed-term pay content whose expiration date has expired. In this case, the authentication information received for one fixed-term paid content may be used to extend all valid periods of the plurality of fixed-term paid content that have expired.

At this time, the authentication information is transmitted to the terminal device 100 by encoding the fee-based content providing system 400 including the subscriber's terminal number and the expiration date of the validity period. The terminal device 100 may determine the validity of the authentication information by using the terminal number extracted by decoding the received authentication information. However, the method for encrypting authentication information is not limited to the above, and various embodiments that may be inferred by those skilled in the art are possible.
