Problems solved by technology

First, since a DLL for control of a corresponding application should be developed based on the analysis result of a specific application using reverse engineering, it takes a long time to develop a new DLL
Therefore, security issues may arise during development time
Second, modules that are injected to operate at user level may conflict with other programs, creating stability issues
Third, in DRM processing through the kernel driver, conflicts with other kernel drivers or programs may arise and cause system crashes
Fourth, reduced flexibility due to the development of new kernel drivers in the process of changing the kernel or operating system

Abstract

Provided are an apparatus and method for managing digital rights. An agent unit manages application programs to which DRM is to be applied and rights to contents processed by the application programs to which DRM is to be applied, and encrypt and decrypt the contents processed by the application programs. A rights management unit authenticates a user and manages a user right to the contents processed by the application programs. A kernel API hooking unit monitors input / output of a file through hooking kernel native APIs, requests the rights management unit to verify the user right to the contents to be processed, and requests the agent unit to encrypt or decrypt the contents when the user right to the contents to be processed is verified.

Description

technical field [0001] The present invention relates to a device and method for managing digital rights, and more specifically, relates to a device and method for managing digital rights by hooking into kernel local API (Application Programming Interface). Background technique [0002] Digital Rights Management (DRM) is used to protect various digital content (such as e-books, music, videos, games, software, stock information, images, etc.) technology to disclose information to outsiders. In the past, hackers or viruses carried out most information breaches. More recently, however, there has been a growing call to remedy the shortcomings inherent in existing security solutions as certified insiders or organizations of interest cause information breaches for money. Almost all documents of a business entity are digitized, and systems for sharing digitized documents are increasingly being introduced. Therefore, enterprise DRM (E-DRM) has also been noticed as most representat...
