System and method for maintaining security in providing a streaming service

The present invention relates to a security maintenance system and method for providing a streaming service, and more particularly, to generate a storage location of a content, that is, address data, automatically at a streaming server that provides a streaming service. The present invention relates to a security maintenance system and method for providing a streaming service that changes the address data of a content from time to time by replacing existing address data with a generated new address data to block the use of a streaming service through an unauthorized link of the content.

Due to the development of Internet technology, a large amount of multimedia content consisting of audio and video is being provided to Internet users, and the large amount of multimedia content is difficult to transmit in a batch due to a network related problem. Provided through a so-called streaming service that is divided into transmission.

The streaming service generates content by providing streaming data through a streaming service server application, ie, a Windows media service server or a real server, and provides the content to the user. The security function of most streaming service server applications is that streaming is interrupted when there are a large number of concurrent users. There are several problems, such as phenomenon or server down, so that the content provider can disable or disable the security function of the streaming service server application, so that the contents of the contents through the personal homepage, media search engine, and Warez site can be Unauthorized links may be so frequent that the streaming server side provides content to unauthorized users.

According to the above-mentioned prior art, when an unauthorized user or an unauthorized user is provided with a content through a normal path, it is not easy to charge the user for using the content. Problems arise especially when provided for a fee.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and automatically generates new address data by automatically generating a storage location of content, that is, address data, when a predetermined condition is achieved in a streaming server that provides a streaming service. The content streaming service is provided indiscriminately by changing the address data of the content from time to time by replacing the new address data, and transmitting the data related to the changed address data only to an authorized web server or a user connected to the streaming server through the web server. It aims to solve the security problem of the streaming service by preventing it from happening.

EMBODIMENT OF THE INVENTION Hereinafter, the Example by this invention is described in detail with reference to an accompanying drawing.

1 is an overall block diagram of a system configuration according to the present invention, wherein the main component of the system according to the present invention changes the address data in which streaming data corresponding to multimedia streaming content is stored whenever a certain condition is achieved. As a web server 20 which guides multimedia streaming content provided by the streaming server 10 through a streaming server 10 and a web page that provide a streaming service, and receives changed address data of the content from the streaming server 10. For more detailed description, the changed address data of the content is not received from the user 30 and the streaming server 10 that request the address data of the content provided by the streaming server 10 by accessing the web server 20. Unrelated to transmit relevant data when requested by user 30 Server 40 is also shown.

The streaming server 10 stores data related to each authenticated web server 20, for example, an IP address of each web server, and generates and holds certain conditions such as a predetermined time interval or a predetermined number of user accesses. When the address data of the content is changed, the changed address data is transmitted to the authenticated web server 20. The streaming server 10 stores data related to at least one authenticated web server 30.

The web server 20 obtains a pre-authentication from the streaming server 10 and mediates the user 30 and the streaming server 10, for example, a web server 20 on the side of the streaming server 10. A web server of an internal network) or a web server 20 of an internet service company (hereinafter referred to as a web server of an external network) having a certain contractual relationship with the streaming server 10 side. When the streaming server 10 changes the location information where multimedia streaming content is stored, that is, the address data of the content and transmits it to the web server 20, the web server 20 stores the existing address data of the stored content. Is updated with the received new address data, and when the user 30 requests the content transmission by clicking the hyperlink text, the updated address data of the content is transmitted.

The user 30 is a client that wants to receive the content provided by the streaming server 10 through the web server 20 or the unrelated server 40. When the user 30 requests the content transmission through the web server 20, Since the web server 20 stores the correct address data of the content, the address data of the content is delivered to the user 30 so that the user 30 accesses the streaming server 10 and receives the content requested for transmission. However, when requesting content transmission through the unrelated server 40, it is highly unlikely that the unrelated server 40 does not store the correct address data, and thus it is almost impossible for the user 30 to receive normal content. Do.

In addition, even when the user 30 obtains the address data of the content from the web page of the authenticated web server 20 and accesses the streaming server 10 directly, the streaming server 10 side of the content is received while the streaming data is being received. In the case of changing the address data, the streaming server 10 does not transmit the changed address data so that subsequent streaming data cannot be received.

The unrelated server 40 attempts to provide content held by the streaming server 10 by linking address data of the content provided by the streaming server 10 without authorization from the streaming server 10 without authorization. For example, there is a personal homepage, a Warez site where a software or content is illegally traded, or a system for operating a multimedia search engine.

Since the unrelated server 40 does not receive the changed address data when the streaming server 10 changes the address data of the content, the probability that the unrelated server 40 has the correct address data of the content is very low, and thus the user 30 ) Cannot transmit the correct address data of the content when requesting the content transmission, so that the user 30 is not provided with the content requested for the transmission. Thus, an unexpected unauthorized third party, that is, the unrelated server 40 It is almost impossible for the user 30 who wishes to access the streaming server 10 to receive content without permission.

Figure 2 is a block diagram showing an embodiment of the configuration of the streaming server 10 and the web server 20 according to the present invention, as shown in the streaming server 10 is the address change module 11, log processing module (13), encryption module (14) and synchronization module (12), and web server (20) includes decryption module (21) and address update module (22).

The address changing module 22 generates new address data of the multimedia streaming content that is retained when certain conditions such as a predetermined time interval or a certain number of user accesses are achieved, and replaces the existing address data with the generated new address data. It is a means to change address data.

The log processing module 13 is a means for recording changed address data, changed date and time data and error data in a log file, and the encryption module 14 transmits the changed address data of the streaming server 10 to the web of an external network. In order to prevent the information related to the changed address data from being disclosed to the third party when transmitting to the server 20, the address data is encrypted before being transmitted to the web server 20 side.

The synchronization module 12 changes the address data of the content on the streaming server 10 side to transmit or request content between the streaming server 10 and the user 30 or between the streaming server 10 and the web server 20. The streaming server 10 and the user 30 or streaming by transmitting the synchronized streaming data to the user 30 side and the changed (or encrypted) address data to the web server 20 side so as not to cause problems It is a means for synchronization between the server 10 and the web server 20.

The decryption module 21 is a means for decrypting the encrypted address data received from the streaming server 10, the address update module 11 is a means for updating the existing address data with the changed address data.

FIG. 3 is a flowchart illustrating one embodiment of the method according to the present invention under the system configuration of FIG. 2. Hereinafter, an embodiment of the method according to the present invention will be described in detail with reference to the flowchart of FIG. 3.

First, when a predetermined condition is achieved, the address changing module 11 of the streaming server 10 changes address data by generating new address data of contents and replacing existing address data (S300). The constant condition may include a predetermined time interval or a predetermined number of user connections.

At this time, there are two ways to generate the address data of the content. One is to extract one of the address data stored sequentially or randomly if the condition is achieved while generating and storing a lot of address data in advance. The other is to generate address data according to certain rules whenever a condition is achieved. Both methods imply some risk of exposure, so choose an appropriate method and apply it to minimize the risk of exposure.

Subsequently, the log processing module 13 records necessary data such as changed address data, changed date and time data, and error data in a log file (S310).

Subsequently, the streaming server 10 checks whether the web server 20 of the external network exists by referring to data related to the stored web server 20, for example, an IP address (S320), and as a result, the web of the external network is checked. If the server 20 is present, the encryption module 14 encrypts the changed address data before transmission to prevent exposure of the changed address data to a third party during transmission to the web server 20 via an external network. (S330).

Finally, since the synchronization module 12 changes the address data of the content between the web server 20 or the user 30, there is no problem in the content transmission or request, that is, the streaming server 10 and Send the synchronized streaming data to the user 30 side to synchronize between the web server 20 or the streaming server 10 and the user 30, and change (or encrypted) address data to the web server 20 side. It transmits (S340).

Thereafter, the address update module 11 of the web server 20 of the internal network receiving the changed address data updates the existing address data with the new address data received from the streaming server 10 so that the user 30 may change the content. When requesting the transmission, the web server 20 transmits the changed address data to the user 30, and the user 30 receives the content by accessing the streaming server 10 with the address data.

Meanwhile, the decryption module 21 of the web server 20 of the external network that receives the encrypted address data decrypts the encrypted address data, and the address update module 22 converts the existing address data into the decrypted new address data. When the user 30 requests content transmission by updating, the web server 20 transmits the changed address data to the user 30, and the user 30 has the address data to the streaming server 10. You will be provided with content.

On the other hand, while receiving streaming data, the address data of the content is changed, and the user 30 receiving the remaining synchronized streaming data receives and reproduces the streaming data. The user 30 refers to a user who has been provided with content by accessing the streaming server 10 through a normal path, that is, an authenticated web server 20. Accordingly, the user 30 arbitrarily, i.e., the user 30 accessing the streaming server 10 by directly obtaining the address data of the content from the web page provided by the non-related server 40 or provided by the web server 20 receives the streaming data. If the address data of the content is changed on the way, the remaining streaming data cannot be received.

The configuration and operation of the present invention have been described in detail with reference to the preferred embodiments as described above. In the above embodiment, but described as a web server and a streaming server, the present invention is not limited thereto. For example, by configuring two or more servers, any one of which is configured as a server that performs an authentication function like the web server, and another server is configured as a server providing a service, thereby performing access to the service providing server. If the server is to be limited, the present invention can be applied as it is in any case.

According to the present invention, the streaming server providing a streaming service changes the address data of the content from time to time, and transmits data related to the changed address data only to an authenticated web server or a user connected to the streaming server through the web server. Unauthorized use of content by unauthorized third parties can be prevented. Furthermore, by preventing unauthorized use of content by unauthorized third parties, it may contribute to the settlement of paid content services.
