Resource Delivery Systems and Methods {SYSTEM SUPPLYING RESOURCE AND METHOD THEREOF}

The present invention relates to a system and a method for providing a resource, and more particularly, to a system and a method that can effectively block illegal copying and use of resources.

3D modeling has been used in a wide variety of industries such as architecture, interior, and computer graphics, and has been in the spotlight in that it can pre-implement the virtual result closest to reality. In particular, the recent popularity of the movie 'Avatar' shows that the public is getting more interested in three-dimensional 3D content than in two-dimensional 2D. The 3D craze is blowing. In order for a single 3D scene to be fully realized, a number of 3D models that can fully realize a sense of space and a three-dimensional effect according to a viewpoint must be well combined. As a result, a worker draws a 3D model according to a situation or expresses it by using existing resources, but it is not easy to draw or own various objects. Therefore, according to standardized specifications, 3D graphic workers may share and utilize resources such as 3D models that have been worked in advance, or purchase and use necessary resources.

Today, resources such as images, sounds, 3D models, animation data, and scripts are available to people around the world, both in the medium of the Internet and in wired and wireless environments. In particular, as internet usage becomes more active, more and more people are provided with resources online to produce a desired type of content.These resources are downloaded to a terminal by being included in a script in an HTML file and called. Used or recycled.

However, because resources are inherently vulnerable to unauthorized distribution and use, they are easy to be illegally copied and used, and may incur disadvantages to the copyright holder who created the resource with a great deal of capital and effort, or to a buyer who purchased the resource normally. Illegal use of resources is a social issue. Therefore, there is a need for a method for preventing illegal copying of resources.

It is an object of the present invention to provide a system and method that can effectively block illegal copying and use of resources.

In order to achieve this object, the resource providing system according to the present invention includes a script parser, a resource downloader, a resource checker, and a resource engine. The script parsing unit parses the location information and the usage information by reading a script that describes location information on the location of the resource to be used and usage information required to use the resource. The resource downloader downloads the resource to be used based on the location information according to the parsed result. The checker checks whether the resource is a valid resource. The resource engine controls only resources determined to be valid resources as a result of the check to be used according to the parsed usage information.

As described above, according to the present invention, when a purchaser purchases a resource from a copyright company, the buyer specifies the domain address to use the resource and location information to store the resource to the copyright company, and the copyright company encrypts the domain address to be used for the resource and the location information to be stored. The user terminal checks whether the downloaded resource is a valid resource and plays the resource only when it is valid, thereby preventing unauthorized copying, distribution, and unauthorized use by others. This protects the rights and interests of buyers and copyright companies.

In particular, when checking the validity of a resource using a domain address where a resource is provided and location information where the resource is stored, security may be improved than when only one piece of information is used.

The inspection by the domain checking means prevents the resource from being played at other domain addresses except for the specific domain address. For example, if a specific domain address specified in the resource is 'www.daum.net' and the user wants to use the resource on a web page provided by 'www.naver.com', the resource cannot be played. Inspection by location information inspection means prevents others from illegally copying resources. If the URL specified in the resource is 'www.rmall.com/path/a' and the URL downloaded by the user is 'www.tmall/path/b', the resource cannot be played. In addition, through the inspection by the tampering inspection means, it is possible to prevent others from modifying the domain address or URL specified in the resource for illegal use.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Further, in the description of the embodiments of the present invention, specific values are merely examples, and exaggerated values may be presented for convenience and understanding of the present invention.

<Description of System>

1 is a view showing a schematic configuration of a resource providing system according to an embodiment of the present invention.

Referring to FIG. 1, the resource providing system 100 of the present invention includes a resource server 110, a web server 120, and a user terminal 130.

The resource server 110 is a server operated by a copyright company (copyright owner) and stores resources to be sold. Here, the resource means data in the form of a file such as an image, a sound, a 3D model, animation data, graphic elements, and a script. When purchasing a resource, the purchaser must specify a domain address to use the resource and decide whether to place the purchased resource on its own server or on the copyright server's resource server 110. If the buyer decides to place the resource on his or her server, he or she may specify the URL where the resource will be stored. If the buyer decides to place the resource on the resource server 110, the buyer is automatically provided with the URL. First, in an exemplary embodiment, a case in which a buyer decides to place a resource in the resource server 110 will be described. The copyright company encrypts the URL information and stores the URL information in the resource server 110 and transmits the corresponding resource according to the user's resource download request.

The web server 120 provides a web page (HTML file). A script may be inserted in an HTML file provided by the web server 120. The script may include a series of address information used to call a resource, that is, an address where the resource is stored and a resource needed for use (replay). Information and so on.

The user terminal 130 checks the HTML file provided by the web server 120, downloads the resource used in the script included in the HTML file from the resource server 110, and plays back the resource only when it is validated. For this, the interface unit 131, the script parser 132, the resource download unit 133, the resource checker 134, and the resource engine 135 are configured.

The interface unit 131 receives a command from a user and displays a result according to the user. The interface unit 131 may be configured by one means or may be configured by an input means and a display means.

The script parsing unit 132 reads a script describing the location information about the location of the resource to be used and the usage information necessary for the use of the resource when the user manipulates the interface unit 131 to access the HTML file. Parsing

The resource downloader 133 downloads the corresponding resource to be used based on the location information according to the result parsed by the script parser 132. This is done by downloading a script via a URL and downloading the resources it is using. Or, it can be executed by downloading a script via a URL, downloading the scripts referenced by this script, and downloading the resources they are using.

In this case, the resource may include use location information on a domain address where the resource is to be used or storage location information on a location (URL) where the resource is stored. For example, the usage location information refers to an address where a resource is provided, such as 'www.tri-d.com', and the storage location information refers to an address corresponding to the resource, such as 'www.rmall.com/path/file name'. . As described above, the location information included in the resource is information compared with the location information where the resource is actually reproduced later in order to prevent illegal duplication and the like.

In addition, the resource includes a hash value calculated for some or all of the resource including the usage location information and the storage location information, that is, a value composed of a combination of letters and numbers calculated using the data. The reason for including the hash value for the data corresponding to the use location information and storage location information of the resource is to check if the use location information and storage location information of the resource changes. The hash value used at this time may be generated using various algorithms such as MD5 and CRC32, but the invention is not limited by the generation method.

When the user inputs a command through the interface unit 131, the resource inspecting unit 134 checks whether the resource downloaded by the resource downloading unit 133 is a valid resource. For this purpose, the resource inspecting unit 134a, And at least one of the position information inspection means 134b or the modulation inspection means 134c.

First, the domain checking means 134a checks whether the usage location information included in the resource matches the domain address actually used. When a buyer specifies a resource purchased by a copyrighter to be played at a specific domain address, the copyrighter reflects this on the resource and designs the code so that the resource is played only at the specific domain address. When the user plays the downloaded resource to his user terminal 130, the domain checking means 134a checks whether the domain address actually reproduced matches the specific domain address included in the resource.

The location information checking means 134b is to check whether the storage location (URL) information included in the resource matches the location (URL) information of the actual resource download. The URL specified in the resource and the URL from which the actual resource is downloaded Check whether this matches.

The modulation check means 134c calculates a hash value for some or all of the resources downloaded to the user terminal 130, and checks the modulation by comparing the hash values included in the downloaded resources. . Comparing the hash value calculated for the part or all of the downloaded resource by the modulation test means 134c with the hash value included in the resource downloaded to the user terminal 130, the usage location information or the storage location information stored in the resource This is to prevent random change of the data. If the location information or storage location information inside the resource is changed, the hash value of the resource data including the data is changed, so that the original hash value and the newly calculated hash value are compared. You can check whether the data has been tampered with. The resource engine 135 controls only resources determined to be valid resources as a result of the check in the resource inspecting unit 134 to be used according to the parsed usage information. If it is determined that the resource is not valid, the resource cannot be regenerated. Therefore, only resources purchased through legitimate procedures can be used.

According to the present invention, the purchaser specifies the domain address to use the resource and the location information to store the resource to the copyright provider when purchasing the resource from the copyright provider, and the copyright provider encrypts the domain address to be used and the location information to be stored in the resource In addition, as the user terminal 130 checks whether the downloaded resource is a valid resource and implements the resource to be reproduced only when it is valid, the user terminal 130 can prevent illegal copying, distribution, and unauthorized use by others, thereby protecting resource use safely. Therefore, it protects the rights and interests of buyers and copyright companies. In particular, when checking the validity of a resource using a domain address where a resource is provided and location information where the resource is stored, security may be improved than when only one piece of information is used.

The inspection by the domain checking means 134a prevents the resource from being reproduced at other domain addresses except for the specific domain address. For example, if a specific domain address specified in the resource is 'www.daum.net' and the user wants to use the resource on a web page provided by 'www.naver.com', the resource cannot be played. In addition, the inspection by the location information inspection means 134b prevents others from illegally copying resources. If the URL specified in the resource is 'www.rmall.com/path/a' and the URL downloaded by the user is 'www.tmall/path/b', the resource cannot be played. In addition, through the inspection by the tamper checking means 134c, it is possible to prevent others from modifying the domain address or URL specified in the resource for illegal use.

On the other hand, the resource includes information on the contact of the copyright holder of the resource, and the resource inspecting unit 134 transmits the test result to the copyright holder of the downloaded resource, if it is determined that the downloaded resource is invalid. In the present invention, the contact information of the copyright holder includes a telephone number, an email address, a fax number, and the like, and the test result is transmitted in real time to the terminal of the copyright holder through a telephone contact, an email, an SMS, a fax, and the like. According to such a configuration, it is possible to easily and promptly check whether the resource is illegally copied and used, and therefore, there is an effect capable of quick response.

Hereinafter, a description will be given of the resource providing system according to the case where the purchaser puts the purchased resources on its own server.

2 is a diagram illustrating a schematic configuration of a resource providing system according to another exemplary embodiment of the present invention.

Referring to FIG. 2, the resource providing system 200 of the present invention includes a resource server 210, a web server 220, a user terminal 230, and a purchaser server 240.

The buyer server 240 is a server operated by a buyer company (buyer) and stores resources purchased from a copyright company. That is, when a buyer purchases a resource, the buyer must specify a domain address to use the resource, and decide whether to place the purchased resource on his / her buyer server 240 or the copyright company's resource server 210. If the user decides to place the server 240, it is necessary to specify the URL where the resource will be stored. Then, the copyright company encrypts the URL information and stores the URL information in the purchaser server 240 and transmits the corresponding resource according to the resource download request of the user terminal 230. By this configuration, the user terminal 230 checks the HTML file provided by the web server 220, downloads the resource used in the script included in the HTML from the purchaser server 240, and checks the resource only if it is valid. Play it back. Looking at the above, unlike in one embodiment, the resource is stored in the buyer server 240, and the role and effect of the other components (210, 220, 230) is similar to that described above and will be omitted.

<Description of Method>

A resource providing method according to an embodiment of the present invention will be described with reference to the flowchart shown in FIG.

1. Resource Purchase Step <S310>

A purchaser purchases resources such as images, sounds, 3D models, animation data, graphic elements, and scripts from a copyright company. When purchasing, the purchaser specifies a domain address to use the resource, and purchases the purchased resource in its own buyer server (240). It should be determined whether or not to put in the resource server 110 of the copyright provider. If the buyer decides to place the resource on the buyer server 240, the buyer may specify the URL where the resource is to be stored. If the buyer decides to place the resource on the server 110, the URL is automatically provided to the buyer.

2. Resource saving step <S320>

The URL information specified in step S310 is encrypted and stored in the purchaser server 240 or the resource server 110.

3. Web server access step <S330>

A user accesses an HTML file provided by a web server through the user terminal 130. Here, the script is inserted in the HTML file, and the script includes address information for calling a resource, which will be omitted since it has been described in detail in the description of the system.

4. Resource parsing step <S340>

When the HTML file is checked in step S330, the script reads the location information regarding the location of the resource to be used and the usage information necessary for the use of the resource, and parses the location information and the usage information.

5. Resource download step <S350>

The resource to be used based on the location information is downloaded to the user terminal 130 according to the result parsed in step S340. This is done by downloading a script via a URL and downloading the resources it is using. Alternatively, it can be executed by downloading a script via a URL, downloading the scripts referenced by this script, and downloading the resources they are using.

At this time, in order to prevent illegal copying and unauthorized use of the resource, the resource preferably includes information on the location of use of the domain (Domain) address where the resource is to be used or storage location information on the location (URL) where the resource is stored.

In addition, in order to prevent the location information of the resource on the browser as it is for security issues, the resource has a hash value calculated for some or all of the resource including location information and storage location information, that is, letters and numbers. It is preferable to include the value made by the combination of.

6. Check for valid resources step <S360>

The user terminal 130 checks whether the resource downloaded to the user terminal 130 is a valid resource in step S350.

In step S360, it is checked whether the usage location information included in the resource matches a domain address that is actually used, or whether the storage location (URL) information included in the resource matches the location (URL) information where the actual resource is downloaded, or Or calculate a hash value (e.g., a combination of letters and numbers such as 192ED60F4B0B603910A3BF) for some or all of the downloaded resources, and compare it with the hash value included in the downloaded resource One or more of the tests are involved.

7. Resource Regeneration Step <S370>

As a result of the check in step S360, only resources determined to be valid resources are controlled to be used according to the parsed usage information. If it is determined that the resource is invalid, the resource cannot be regenerated.

In step S360, if the location information included in the resource is checked to match with the domain address actually used, for example, the specific domain address specified in the resource is' www.daum.net ', and the user is' www.naver.com If the resource is to be used on the web page provided by ', it checks whether two domain addresses match. As the two domain addresses do not match, the resource cannot be reproduced. According to this process, the resource can be prevented from being played at other domain addresses except for the specific domain address.

Next, in step S360, if the storage location (URL) information included in the resource is checked to match the location (URL) information of the actual resource download, if the URL specified in the resource is' www.rmall.com/path / a ', but the URL downloaded by the user is' www.tmall/path/b', the resource cannot be played. Accordingly, it is possible to prevent others from illegally copying resources.

Finally, in step S360, when the hash value is calculated for some or all of the downloaded resources, and the tampering is checked by comparing the hash value included in the downloaded resource, the third party uses the domain address or URL specified in the resource. It can be modified to prevent illegal use.

According to the present invention, the purchaser specifies the domain address to use the resource and the location information to store the resource to the copyright provider when purchasing the resource from the copyright provider, and the copyright provider encrypts the domain address to be used and the location information to be stored in the resource In addition, as the user terminal 130 checks whether the downloaded resource is a valid resource and implements the resource to be reproduced only when it is valid, the user terminal 130 can prevent illegal copying and unauthorized use by others, so that the rights of buyers and copyright companies It has the effect of protecting profits. In addition, as described above, when checking the validity of a resource using a domain address where a resource is provided and location information in which the resource is stored, security is improved than when only one piece of information is used.

The method for providing resources according to the present invention may be implemented in the form of program instructions that can be executed by various computer means and recorded in a computer readable medium. The computer readable medium may include program instructions, data files, data structures, etc. alone or in combination.
