Authorization management method and system for digital copyright management

The present invention relates to a method and system for authorizing management and control, and in particular to a method and system for managing digital content authorization of a digital rights management system. Furthermore, the present invention is a technique for creating a many-to-many relationship between a digital rights management system and a digital content service platform.

The digital rights management system is an encryption protection system for preventing unauthorized reading, copying, and propagation of digital content. If a digital content service uses a digital rights management system to protect digital content, when the user's terminal device wants to read a bit of content, it must obtain authorization from the digital rights management system and obtain decrypted information. In the process of confirming the authorization, the digital copyright management system must ensure that a terminal device has the right to read a digital content, and also ensure that the terminal device can acquire and occupy a digital copyright distributed by the digital copyright management system. Manage device licenses. If a digital rights management system has no digital rights management device license available, the new terminal device will not be able to successfully obtain authorization for this purpose. Therefore, if you want to control the content authorization of a digital rights management system, the management of digital rights management device licenses is also an indispensable part. The Republic of China Patent Publication No. 20103588A1 proposes an authorization management system and method thereof for recording a login time and an identification message through an authorization record table, and as a judgment basis for a recycling authorization when the authorized amount is exceeded. However, it only controls the number of devices in a system, and lacks the considerations of combining with the digital copyright management system, so it does not have to deal with it. The effectiveness of the authorization requests of various digital rights management systems cannot control the number of digital rights management device licenses of different digital rights management systems according to the needs of different digital content service platforms.

In addition, when a digital content service adopts a digital rights management system, the terminal device of the user must be equipped with the digital rights management terminal software (DRM client agent) of the digital rights management system to decrypt and restore the digital content. However, in recent years, with the variety of terminal devices and operating systems, the digital rights terminal software installed in different terminal devices is not the same, and if the non-native digital copyright terminal software is installed, it is easy to be incompatible with the system environment. working normally. Because the current digital rights management system still uses a single digital content service platform to use only a single digital rights management system architecture, this will not be able to cope with the diversification of terminal devices. In order for various terminal devices of a digital content service user to read protected digital content with different digital copyright terminal software, the digital content service must simultaneously adopt more than one digital rights management system. However, the digital copyright management protection mechanism does not enforce uniform specifications, so different digital rights management systems are not interoperable, which is a major limitation for the majority of copyright management needs. In order to improve the interoperability of multiple digital rights management systems, the Republic of China Patent I315629 invents a system and method for converting digital copyright management files into different specific formats by using different digital rights management file formats to solve the same system supporting multiple digital rights management. File format issues. Firstly, the digital content files encrypted by various digital copyright management systems are converted into the same format to be provided to the terminal device, so the user terminal device only needs to install the digital copyright terminal software of the method to decrypt the digits of the plurality of digital copyright management systems. content. However, the file encryption protection methods of various digital copyright management systems are mostly confidential information, so it is difficult to implement various file conversion technologies. U.S. Patent No. 20150033284A1 proposes a method for generating a secure channel, downloading and installing a plurality of digital rights management terminal software, in order to cope with the problem of majority copyright management. However, the method needs to be implemented before the terminal device installs a specific terminal software, so it also faces the aforementioned non-native Software system compatibility issues. The above-mentioned predecessors are aimed at solving the problem of majority copyright management from the digital content format and the terminal device, but there is still a lack of discussion on the authorization processing of the content. For a digital content service platform, without the integration of multiple digital rights management systems, there will be a lack of consistency in the process of determining authorization between different systems.

Finally, although a digital content service can protect its digital content through a digital rights management system, the cost of independently building and operating a digital copyright management system is costly, and it has a very high import threshold for small and medium-sized businesses. . Therefore, if a digital rights management system can be used for multiple digital content services at the same time, the cost of the digital content service provider can be reduced, and the digital copyright management system holder can also improve the utilization of resources.

It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good design, but needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally succeeded in researching and developing this authorization control method and system suitable for digital copyright management.

The object of the present invention is to propose an authorization management and control method and system suitable for digital copyright management, which can process and process the authorization requests of multiple digital rights management systems in a unified manner.

The second object of the present invention is to provide an authorization management and control method and system suitable for digital copyright management, which is to make a digital content without changing the structure of the existing digital copyright management system. The service platform can simultaneously use multiple digital rights management systems, and enables a digital rights management system to be used by multiple digital content service platforms at the same time.

A further object of the present invention is to provide an authorization management and control method and system suitable for digital copyright management, which enables a user terminal device of a digital content service platform to use different digital rights management terminal software to read and manage by different digital rights. Digital content protected by the system.

An authorization management method and system suitable for digital copyright management to achieve the above object is based on a digital copyright management system, a digital content service platform, a terminal device, an authorization record and statistical data management, and a number of digital rights management device licenses. The control mechanism is configured to receive and process the digital content authorization request of the digital rights management system, and the authorization request of the intermediary digital rights management system to the digital content service platform for determination. The content authorization of the factor-based copyright management system is limited by the number of licenses of the digital rights management device, so this issue is considered at the same time when the authorization request of the digital rights management system is controlled. The number of device licenses provided by different digital rights management systems is different from the number of device licenses used. Therefore, when a digital content service platform uses multiple digital rights management systems, it must specify the digital rights management system. The number of digital rights management device licenses and the number of usage counts. Thereafter, when the system receives an authorization request from a digital rights management system for a terminal device, the system performs authorization processing in cooperation with the verification and regulation mechanism of the number of licenses of the digital rights management device. As for the authorization or not, the decision is based on the needs of different digital content service platforms, which may be determined by the digital content service platform, or determined by the system preset logic, or with information related to the content of the authorization request from other information systems. For the basis of the judgment.

The system proposed by the invention comprises three modules: (1) a data management module: for managing data of a digital copyright management system, a digital content service platform, a terminal device, an authorization record and statistical data, and receiving the following requests: Data registration request and digital content service of digital copyright management system Data registration request of the platform, data registration request of the terminal device of the digital content service platform; (2) Authorization management and control module: for receiving and processing authorization requests of different digital rights management systems, and calling the digital rights management device license control module Regulating the number of licenses for digital rights management devices and querying other information systems for information related to the content of the authorization request; (3) Digital rights management device license control module: used to verify and regulate the available in the digital rights management system Number of digital rights management device licenses.
