System and Method for using adaptive agent to secure digital resource in an intellectual property rights management system environment

The present invention relates to a digital intellectual property management system and method using an adaptive agent, and more particularly, an adaptive agent (User) to the user terminal to systematically and effectively protect and manage intellectual property rights for various digital works A digital intellectual property management system and method for dynamically protecting the use of digital works and precisely managing digital copyrights for each user, and a computer-readable recording medium recording a program for realizing the method. It is about.

With the rapid growth of the distribution environment for digital contents due to the rapid increase of Internet users and the development of multimedia and network technology, the most problematic problem is the interest in systematic and effective copyright management of various works in the digital form. One is that if a protection method for a digital work that has already been introduced through a specific protection technology is known by the hacker or the user of the work, then a new method of protection for the digital work has to be put in place. There are many cases in which an additional cost of applying a new protection method is incurred, which causes enormous damage to the copyright holder or the digital asset service provider.

Conventional techniques include developing cryptographic, digital signature, digital watermarking, or new rendering tools to deal with the protection of digital copyrighted works. The new methods of protection are expensive because new methods of protection cannot be actively changed. Furthermore, if a new player is newly developed, there is a problem that the compatibility of the digital asset is lost and the user is forced to use the particular player.

Here, in the case of the encryption method, since the digital work can be used by an illegal user after the decoding process, the protection and management of the intellectual property is made difficult in reality, and digital signature and digital watermarking are also difficult. In this case, too, there is a problem in that control over illegal utilization cannot be achieved in real time.

Since the use of most digital works can occur in both online and offline cases, there is a need for protection techniques that can adapt to the user's environment. In other words, since the digital works received in the online state are used after being stored in the user environment, the protection and management technology that can cope with the situation according to the situation when the conversion to the offline base is required.

As a result, a service that monitors the user's environment in which digital works are continuously played regardless of online and offline status is put in place, so that the services must be running in order to use the work, and this service manages the user's work and playback unit. Or, if controllable, continuous digital intellectual property management can take place.

On the other hand, the right to use and rights for digital works are handled by the copyright holder or the copyright service, and with the introduction of the e-commerce service, which is gradually spread, it is necessary to change the real-time copyright rights and conditions or change the usage rights. That is, the conventional method is distributed to the user after protecting the digital work for a specific purpose, this method is difficult to apply quickly because the definition of the application of new rights and conditions by the copyright holder is not systematically there was.

If the copyright holder or the right holder can be notified in real time about the use of their digital works, and based on this, a new strategy can be defined and applied to the work delivered to the user in real time. By strengthening the method and providing a fast e-commerce introduction model, users can be provided with credibility, and service providers and copyright holders can be provided with opportunities to develop various strategies for inputting digital works.

Therefore, rather than simply developing protection technologies to prevent illegal use of digital copyrighted works, systematic management of digital copyright information, accumulation of information on the use and illegal use of copyrighted works, the integration of existing digital copyrighted services and operations, and a single rule for the user environment It is essential to develop a system that can maintain compatibility based on changeable monitoring and protection services.

The present invention has been proposed to solve the above problems, by applying an adaptive agent to the user terminal to achieve a systematic digital intellectual property protection and management while maintaining compatibility by using existing digital works and players as it is In addition, adaptive agent-based digital intellectual property rights for digital works can be continuously checked for usage rights and conditions for the use of digital works, and also enable copyright holders to change the strategies and definitions of digital works in real time. It is an object of the present invention to provide a management system, a method thereof, and a computer-readable recording medium having recorded thereon a program for realizing the method.

The present invention applies an adaptive agent to a user terminal (for example, a PC, etc.) capable of playing a variety of digital works to ensure continuous digital intellectual property protection and management in an online or offline environment will be.

That is, the present invention provides an adaptive agent to a user terminal in order to systematically and effectively protect and manage intellectual property rights of various digital works, thereby dynamically protecting the use of the digital work and applying accurate digital rights for each user. The Digital Intellectual Property Rights Management System, which manages copyright delivery methods and copyright definitions, is an event related to the use of most copyrighted works in the user's computer environment. By monitoring the system, it prevents illegal use and records a series of related tasks, so that the adaptive agent's monitoring and protection rules can be changed dynamically according to the user's environment.

To this end, the present invention provides an adaptive agent to effectively prevent the ever-increasing number of digital contents and various infringement of Intellectual Property Rights and illegal usage generated from various commercial services. We will build an effective Trusted User Environment through a systematic multilevel asset management and protection service.

Conventional digital rights management systems use cryptographic, digital signature, digital watermarking, or dedicated rendering tools to restrict the use of digital copyrighted works. However, the present invention does not restrict the use of a specific player for the copyrighted work, thereby maintaining broader compatibility. In this case, the adaptive agent directly controls through various events generated in the user operating environment so that the user can systematically monitor or limit the use of the digital asset. Therefore, usage methods other than the rights and conditions for digital works granted to the user are automatically blocked by the adaptive agent.

In other words, by applying an adaptive agent to the user terminal, it operates a multi-level protection and monitoring service to carry out the copyright rights and conditions of digital works, records the pattern of illegal use of the user, and establishes a new management policy based on this. The new policy for digital works can be applied to the same user service in real time.

The present invention authorizes the use of a digital copyrighted work and makes the digital copyrighted work a copyrighted package, and the package to be delivered includes the user information, copyrighted information, rights and conditions granted to the user, as well as the contents of the digital copyrighted work. The usage records can be included in the package of their own works, so that the movement of the package or the use of digital works in different user environments can be recorded for each digital work.

An adaptive agent-based user terminal (see FIG. 2) according to the present invention is composed of a work package receiving unit, a work utilization monitoring and protection agent, a user protection environment construction unit, and the like. (Refer to "560" in FIG. 5) is characterized in that when the user's terminal is online with the digital intellectual property management server, it is transmitted to the digital intellectual property management server so that the record data can be updated.

The asset package used in the present invention is defined for all rights and conditions that can be utilized by the user for the digital asset, and since the management methods for the actual digital asset are included, the protection and monitoring methods for individual assets are differentiated. It is configured to be. In other words, even if you hack an asset package for a specific digital asset, it is configured to not understand all of the protection and management information recording method for the other asset package.

Handles the decryption of the digital asset package 500.

Throughout the work through the package interpreter 223, the user environment has already been converted to a protected environment, and the agent 210 is operated. Various system events generated by the user terminal 20 can be monitored and protected. 214 is monitored and the message generated through the user operating system 26 in the system is also monitored, and upon detection of a pattern for illegal utilization, the process is terminated without any further processing, and the contents of the package and the user are terminated. It is stored in the database 24 of the environment. In the normal method of using the asset package 500, the virtual file system 232 is driven while the digital asset package 500 is decoded by the package interpreter 223 to designate a place to store the decrypted digital asset 550. do.

The virtual file system 232 illustrated in FIG. 2 is for operating the secure virtual file system 232 without extracting the digital asset 550 from the asset package 500 and sending it to the general file system. That is, even when the digital asset 550 is extracted from the asset package 500 and utilized by the asset reproduction unit 25, the digital asset 550 may be accessed through another service or program of the user terminal 200. It is to limit the number.

In the user terminal 20, even when the system is powered off or forcibly terminated, the virtual file system 232 is secured and cannot be accessed in a state in which the normal 'work utilization monitoring and protection agent' 210 is not driven. Access to the virtual file system 232 is not possible using methods other than normal use.

The package interpreter 223 checks the information in the work package 500 and determines whether it is online. If the user terminal 20 is not in an online situation, an offline work process is performed. Communication with the intellectual property management server 10 is performed through a secure channel 202, which is a secure network communication layer, to transmit and receive various types of information.

The information decrypted by the package interpreter 223 is applied when the digital asset 550 is driven by the player interworking controller 222 and security between the agent modules after the asset player 25 of the user terminal 20 is driven. Through the communication layer 201 through the internal communication process with the 'work use monitoring and protection agent' 21 and the user protection environment construction unit 23 to monitor and limit the user's use of the digital work (550).

The asset utilization monitoring and protection agent 21 receives the monitoring and protection task to be performed while the digital asset 550 is used based on the information generated by the package interpreter 223. The task is defined by the mission analyzer 211, and monitors and protects various resources (ie, user operating systems) 26 of the user terminal through the mission controller 212.

The resource monitor and protector 214 monitors the operating system 26 of the user terminal 20 in accordance with the designated task, and repeats the execution until the use of the digital asset 550 is terminated.

When the operation of the digital asset 650 is finished, the digital asset 550 generated in the virtual file system 232 is deleted along with the virtual file system 232 and copyright usage information, that is, tracking information generated by the use of the asset. In 560, the user's utilization fact is entered and the asset package 500 is returned.

The user protection environment construction unit 23 performs a substantial security role in the user terminal 20, and the event detected in the user terminal is analyzed through the 'production utilization monitoring and protection agent' 21 and the corresponding contents. This is the part that interrupts the execution of the command or performs the function of block copy protections. That is, the user protection environment construction unit 23 is a part that performs a function that can prevent illegal use of the user through the control and virtual file system for the asset reproduction unit because the protection environment must be established in advance.

The user operating system 26 refers to an operating system utilized by the user terminal 20 such as Windows 95, 98, 98SE, Me, NT, 2000, XP and the like. In the present invention, a protection function is performed by monitoring an operating system used by a user so as to maintain extensibility and compatibility.

Authorization information 306, illegal use information 307, fee / cost information 308, asset information 309, asset utilization group 310, tracking and log records 311, copyright holder information 312, creator information 313, registration related information 314, rights (permissions), and condition information 315.

The database of the digital intellectual property management server 10 establishes a relationship between the work information and the information which is formed and stored in the main structure of user information.

All digital works 550 may be created or edited by the digital copyright holder 50 or the owner 50 and may possess one or more copyright holder information, creator information, and registration related information. In order to include copyright information for each digital asset 550, there may also be a definition of one or more asset utilization groups, and each group contains one or more rights and condition information.

As shown in FIG. 3, the user has a group to which the digital asset 550 belongs, and the group is designated as the asset utilization group through rights permission information defined by copyright information. .

The user group information to which the user belongs is again related to the user site information, so that systematic management by site can be achieved.

The use relationship between a user and a specific digital asset is defined by fee / cost information and commerce information generated in accordance with an approved use request, and the purpose and authority of the copyrighted work requested by each individual user can be confirmed.

Various illegal utilization information 560 transmitted from the agent-based user terminal 20 described in FIGS. 1 and 2 is recorded in the tracking information database 125 which stores illegal use information for each user, and the information is tracked and logged. In addition to the record, it is managed for each digital asset 550 requested by the user.

The scope of information managed by the copyright holder (50) or the owner (50) is the copyright information management unit 112 is operated so that you can view the copyright information and protection rules, including the copyrighted work information and the user information about the copyrighted work In addition, the asset distribution site 30 is managed through the user manager 111 to view various group information, user information, and asset transaction information for each user.

4 is an exemplary explanatory diagram of an adaptive agent-based digital intellectual property management method according to the present invention, and shows the overall digital intellectual property management method.

First, the digital intellectual property management method performed in the digital intellectual property management server 10 is as follows.

The digital intellectual property management server 10 receives copyright information about a digital work from a copyright holder or a copyright agency, registers a digital work, and then delivers description information about the registered digital work to a work distribution site.

In addition, the digital intellectual property management server 10 stores / manages information about the user who requested the use of the work according to the user's request to use the work through the work distribution site, and according to the user's permission to use the work, the user information and copyright After the asset package is generated using the information, the generated asset package and usage approval are transmitted to the user terminal.

Then, the digital intellectual property management server 10 receives the usage information on the work from the user terminal, and delivers the reported work use information to the copyright holder or copyright agency.

The digital intellectual property management server 10 receives a new monitoring and protection rule for the copyrighted work from the copyright holder or the copyright agency, updates the copyright information, and then transfers the updated copyright information to the user terminal or the work distribution site.

Hereinafter, FIG. 4 will be described.

First, a copyright holder (creator) 50 for a digital work registers copyright information directly to the copyright information management apparatus 11 (400), or a copyright agency 40 other than the copyright holder 50 is a digital work ( 550 may be received (401) to register or edit the same information (402).

When the digital copyright information is constructed, the asset description information 33 is transmitted through the copyright distribution site 30 for the service of the registered copyright (404). At this time, the asset distribution site 30 registers the user information held in the copyright information management device 11 so that the input and registration of the 'work utilization monitoring and protection agent' 21, which is an adaptive agent for the user, can be made. shall.

The registered user 20 processes the use request for the specific digital asset 550 through the asset distribution site 30 to obtain the right to use the digital asset 550 (405, 406).

The asset distribution site 30 forwards the obtained user's request 405 to the asset control apparatus 12 which manages and protects the asset (406), and the asset control apparatus 12 is provided with respect to the user's information and the asset. The digital asset package 500 is configured with reference to the copyright information.

When the composition of the asset package 500 is completed, the asset control device 12 delivers the asset package 500 to the user 20 through the asset distribution site 30 (409, 410). In operation 20, the user terminal 20 receives the asset package 500 to which the asset package receiving unit 22 is transmitted. The asset distribution site 30 transmits the transaction information for the digital asset to the copyright information management device 11 (415), and the user information for each distributed asset is transferred to the asset control device 12 (416).

The present invention may allow the asset control device 12 to directly deliver the asset package to the user terminal 20 with the permission of use, without transmitting the asset package 500 through the asset distribution site 30 as described above. have.

The asset package 500 delivered according to the copyright definition of the digital asset 550 and the rights and conditions approved by the user runs on the agent-based user terminal 20 and monitors the use of the digital asset 550 by the user. The asset utilization monitoring and protection agent 210 transmits the information and the right update information to the asset control device 12 (exactly, the monitoring and tracking information management unit 124) (411).

User asset usage (utilization) information 125 accumulated in the monitoring and tracking information management unit 124 of the asset control device 12 is transferred to the copyright information management device 11 (412), and the copyright information management device 11 Will report the use of the work to the copyright holder 50 or agency 40 (413, 414).

Meanwhile, the reported digital asset utilization (use) information 125 may be referred to by the asset protection / monitoring control unit 121 of the asset control device to supplement the input protection and management method for the digital asset 550. It is used as basic data information to circulate the whole driving environment.

The asset control device 12 transmits the rights update information for the user to the asset distribution site 30 or the user terminal 20 (417 and 418).

The characteristic of the adaptive agent-based digital intellectual property management system is that the intellectual property management is not terminated by the use and monitoring of the copyrighted work to the end user 20 in the generation stage of the digital asset 550, and the information of the overall system configuration is obtained. Based on this, it is possible to provide continuous management to the use of the digital copyrighted work 550 as a circulatory system that delivers information to the copyright holder 50 and newly introduces new protection and monitoring methods.

5 is a diagram illustrating an embodiment of a composition package for distributing a digital asset used in the present invention.

The asset package 500 delivered to the adaptive agent-based user terminal 20 into which the 'asset utilization monitoring and protection agent' 21 is input is configured to be processed by the asset package receiving unit 22. The package 500 includes various information on how the digital asset 550 can be utilized in the user terminal.

The copyright package 500 is generated by the digital intellectual property management server 10 and includes information about each user and information to be inserted into the copyright package 500 through copyright information.

The copyright package 500 contains unique information used inside the digital intellectual property management server 10, so that the digital intellectual property management server 10, along with various control numbers, monitors and protects the utilization of the deposits of the user terminal. It is configured to control.

The report on the utilization of the work within the actual asset package 500 is not transmitted to a single digital intellectual property management server 10, but is transmitted to a plurality of digital intellectual property management servers 10 or to track usage information. As it may be passed to the third digital intellectual property management server 10, the unique identification of the information is contained in the intellectual property management server internal information portion 510.

The copyrighted user information 520 does not include detailed information about the user, but rather information that can refer to which user 20 the copyrighted work 550 is used.

That is, in the decryption of the asset package 500, when the asset package receiver 22 refers to the internal information of the asset package 500, a key value and a user environment that can be decrypted through the asset user information 520. Confirm the identification of.

The right to use and terms section 530 defines how the digital work 550 can be utilized by the user, and this information can be obtained by additional rights or by changing the rights and conditions by the copyright holder 50. Information that is corrected at the time.

The asset package 500 may be protected and managed through basic rules according to the asset use rights and conditions 530, and detailed asset management and protection may be additional 'agent-monitored and protection rule definition information' (540). Can be activated. The information on the definition of the surveillance and protection rules by the agent 540 is a dynamic component that can be changed further for new surveillance rules to be used illegally or to strengthen the protection environment even after the digital asset 550 is delivered to the user. I have it.

'Definition of tracking information and reporting method generated by the use of the work' (560) includes information related to the utilization of the digital asset 550, the actual asset package 500 and the user terminal 20 is utilized Information is stored in a manner accumulated in the virtual file system 232 managed separately. The 'tracking information and reporting method definition information' generated by the use of the work 560 is transmitted to the digital intellectual property management server 10 when the user terminal 20 is online, and after the transmission, except for the most recent information. The previous information 560 is removed by the digital intellectual property management server 10.

Lastly, even if a user delivers or copies the asset package 500 to the outside through a method of preserving the digital asset 550 usage record in the asset package 500 used in the present invention, 530 is maintained as it is.

In the present invention, since the asset package utilization record 560 of the multi-user is managed, the 'asset utilization monitoring and protection agent 21 operating in the user terminal 20 records the use of each asset package 500. In addition, each asset package 500 has a structure in which the utilization information 560 is also stored, so that the original information 560 can be generated even when either information 560 is lost.

If all the usage records 560 of the asset package of the user terminal 20 are deleted, the right to use the asset and the conditions 530 are based on the final information 560 transmitted to the digital intellectual property management server 10. The ability to regenerate has the advantage of achieving multi-level information retention.

The information finally included in the asset package 500 is inserted with a 'confirmation code for illegal copying' (570), so that all the information is identified when the contents of the information are generated by random modulation rather than by a specified rule. This is possible.

The asset package 500 basically includes a secured digital asset 550. In addition, various pieces of information for copyright management and protection are appropriately encrypted in the user terminal 20. ) Configuration is differentiated.

The asset package 500 used in the present invention may have a different configuration of the asset package 500 so that the asset package 500 may be applied according to the utilization and distribution method of each digital asset 550. There may be a way.

(1) the general asset distribution package method in which all the information (510 to 570) listed in FIG. 5 is inserted, (2) the asset user information 520 and the asset use right and condition information 530 are not inserted, and thus the user (s) Multi-level rights-applied package method in which the use rights and conditions 530 of the work granted to the user are granted according to the certification of (3), and (3) the digital work is packaged by the designated encryption, and the use rights and conditions defined in advance ( 530 is a packaged work for mass distribution or read-only media that is assigned and lacks asset user information 520, and (4) a network address or web that digital work 550 does not exist within the package and is accessible online. In addition to the address (URL: Uniform Resolution Link), your information (520) and your rights and conditions (530) have been inserted, (5) Finally, the user terminal 20 can use the information generated in real time when the asset distribution site 30 is accessed without using the digital asset as a unit. Can be configured as a connection package that allows access after configuring it as a protection and surveillance environment.

FIG. 6 is a flowchart illustrating a digital intellectual property management method in the adaptive agent-based user terminal of FIG. 2 according to the present invention.

First, a digital intellectual property management method performed in the adaptive agent-based user terminal 20 will be described as follows.

The user terminal 20 receives the asset package delivered from the digital intellectual property management server 10 at the user's request, and then decodes the received asset package to extract usage rights and conditions, monitoring and protection rules, and the like. Play a digital asset.

The user terminal 20 uses the asset utilization monitoring and protection agent 21 to monitor the operating system of the user terminal according to the monitoring and protection rules extracted while the digital asset is reproduced and used by the user. The digital intellectual property management server which monitors the utilization status of the digital asset, stops the reproduction of the asset when the illegal use is confirmed, stores the usage state of the copyrighted work, and displays the usage state of the copyrighted work online. To pass).

Hereinafter, FIG. 6 will be described.

When the asset utilization monitoring and protection agent 21 is initialized for driving and the protection environment is set so that the asset is protected / managed in the user terminal (600), the asset package receiving unit 22 uses the asset package 500 when the asset is used. In order to know whether the user terminal 20 can normally perform the protection and monitoring function before the analysis of the asset package 500, the state of the user protection environment building unit 23 is checked (602).

As a result of the check at "602", if the user protection environment construction unit 23 is not properly prepared, after outputting the protection environment absence request and requesting the protection environment reset (604), the operation on the package 500 is not processed. Do not.

As a result of the check at " 602 ", if the driving of the protection environment building unit 23 is confirmed (i.e., the protection and monitoring environment is set), it is checked whether the user terminal 20 is online (606). State, the cumulative record (that is, tracking information generated by the use of the asset such as the store use record and the surveillance information) contained in the asset package 500 is transmitted to the digital intellectual property management server 10 (608). In addition, if there is renewal information such as a renewal rule to be newly introduced into the digital intellectual property management server 10, the relevant renewal information is transmitted to the 'work utilization monitoring and protection agent' 21 to use the work according to the updated information. After changing the authority and condition 530 for the server 610, the following process “612” is performed. If the user terminal is not online, the following procedure "612" is performed.

Thereafter, in the step of examining the interpretation and copyright rights of the asset package 500, the rights information (that is, the rights and conditions of use of the asset) 530 that are granted to the user is extracted from the asset package 500 to start the inspection ( 614, to diagnose (check) the suitability for the interpreted / extracted rights information (ie, rights to use and conditions of the work) 530.

As a result of the conformity assessment (check) of "614", if the user's use of the digital work 550 is restricted or the right to use 530 is revoked, the user is informed how to obtain additional rights (616) and the user's decision ( That is, depending on whether the user acquires additional rights) (618, 620) to obtain additional rights (step 620 or less) or terminate the use of the work.

As a result of the conformity assessment (checking) of "614", if the rights and rights 630 are appropriate, the virtual file system 232 is created as a pre-step for extracting the digital asset 550 to generate the digital asset 550. ), The asset utilization monitoring and protection agent 21 performs the monitoring and protection while the asset is in use (622).

After the digital asset is created in the virtual file system 232, the existence of the asset reproduction unit 25 is checked, and the asset reproduction unit 25 is driven to allow access to the digital asset 550 ( 624). Then, the user can utilize the digital asset 550 through the designated asset reproduction unit 25 by the given asset use rights and conditions 530, and in such a situation, the asset utilization monitoring and protection agent 21 prevents illegal use. User operating system 26 is monitored (624) to prevent.

As a result of the illegal use monitoring (626), when the illegal use pattern occurs, the asset utilization monitoring and protection agent 21 immediately stops playing the digital asset 550, and utilizes the asset (560) for the illegal use. If the asset utilization monitoring and protection agent 21 confirms that the user terminal 20 is online, the user's usage pattern and the generated event 560 are immediately recorded. After transmitting to the asset control device 12 of the management server 10 (630), the user is notified of the situation (632), and ends.

As a result of the illegal use monitoring (626), if the user normally terminates the use of the digital asset 550 through the asset reproduction unit 25 (628), the asset utilization monitoring and protection agent 21 is the digital asset (550) Exit protection and monitoring.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited by the drawings.

As described above, the present invention utilizes digital works for the effective management and protection of digital intellectual property rights at the time when various commercial methods for the activation of digital works created by the copyright holder and various commercial methods for existing works are developed online and offline. By inserting an active agent that can adapt quickly to the user terminal environment, the user terminal can be converted to a protected environment when the digital work is utilized, so that the rights and conditions for copyright granted to the user by the copyright holder or the service provider can be safely maintained. It provides effective reliability that can dramatically improve the digital asset utilization environment.
