Description

SERVER AND METHOD FOR REDIRECTING CONTENTS ROUTE}

The present invention relates to a content path bypass server and method.

Recently, as the spread of smart terminals has spread and the network speed has increased dramatically, the use of the Internet enables not only web searching but also video streaming through a mobile communication network, so that video contents can be viewed anytime and anywhere using smart terminals.

At this time, when illegal video or harmful video in violation of copyright is distributed to the smart terminal, the copyright holder was the only countermeasure to delete and report the site where the copyright content was uploaded. Regarding a method of preventing illegal distribution of copyrighted content, in the prior art 2010-0045760, when a digital content transmission command is input, a service for transmitting connection information to a digital content distribution server for the digital content to another terminal Is disclosed.

However, in providing a method for preventing illegal distribution of copyrighted content, it helps to connect to a distribution server when transmitting or receiving digital content, but cannot prevent the streaming of the content itself. Since it is different from the operating system, there is no standard to prevent illegal streaming requests from smart devices. In the end, copyright holders must search and report illegal contents to protect the contents.

According to one embodiment of the present invention, when a smart terminal requests illegal content or harmful content, the request traffic is intercepted without transmitting the request traffic to the data providing server, thereby eliminating the demand for illegal content and providing a source for distributing illegal content. It is possible to provide a content path bypass server and method that can be essentially removed. However, the technical problem to be achieved by the present embodiment is not limited to the technical problem as described above, and other technical problems may exist.

As a technical means for achieving the above technical problem, an embodiment of the present invention is a receiver for receiving traffic transmitted from the mobile terminal to the data providing server, a classification unit for classifying the content request traffic from the traffic, the content request traffic A content path bypass server including an analysis unit for analyzing whether the content requested by the mobile terminal is blocked content and a path bypass unit for transmitting a block message to the mobile terminal if the content requested by the mobile terminal is blocked content; Can provide.

In addition, another embodiment of the present invention, receiving the requested traffic to the data providing server for providing data from the mobile terminal, classifying the content request traffic from the traffic, the request from the mobile terminal through the content request traffic Analyzing whether the content is blocked content, and if the content requested by the mobile terminal is blocked content, transmitting a block message to the mobile terminal can be provided.

According to any one of the problem solving means of the present invention described above, when requesting illegal content or harmful content from the smart terminal, by blocking the request traffic in the middle without transmitting to the data providing server, eliminating the demand for illegal content and illegal You can essentially eliminate the source that distributes the content.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is "connected" to another part, this includes not only "directly connected" but also "electrically connected" with another element in between. . In addition, when a part is said to "include" a certain component, which means that it may further include other components, except to exclude other components, unless specifically stated otherwise, one or more other features It is to be understood that the present disclosure does not exclude the possibility of the presence or the addition of numbers, steps, operations, components, parts, or combinations thereof.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a content path bypass system according to an embodiment of the present invention. Referring to FIG. 1, the content path bypass system 1 may include a mobile terminal 100, a data providing server 300, and a content path bypass server 400.

In this case, each component of FIG. 1 is generally connected through a network 200. For example, as shown in FIG. 1, the mobile terminal 100 is connected to the data providing server 300 and the content path bypass server 400 through the network 200. In addition, the mobile terminal 100 and the data providing server 300 may be connected through the content path bypass server 400, and the content path bypass server 400 may provide traffic between the mobile terminal 100 and the data providing server 300. It can also be connected in such a way that it is monitored. The network 200 refers to a connection structure capable of exchanging information between respective nodes such as terminals and servers, and an example of such a network 200 may include the Internet, a local area network (LAN), Wireless Local Area Network (WLAN), Wide Area Network (WAN), Personal Area Network (PAN), 3G, 4G, LTE, and the like, but are not limited thereto. In addition, the mobile terminal 100, the data providing server 300, and the content path bypass server 400 disclosed in FIG. 1 are not limited to those shown in FIG. 1.

Referring to FIG. 1, the mobile terminal 100 may be implemented as a computer that can access a remote server through the network 200. Here, the computer may include, for example, a notebook, a desktop, a laptop, and the like, equipped with a web browser. In addition, the mobile terminal 100 may be implemented as a terminal capable of accessing a server at a remote location through the network 200. The mobile terminal 100 is, for example, a wireless communication device that ensures portability and mobility, and includes a personal communication system (PCS), a global system for mobile communications (GSM), a personal digital cellular (PDC), and a personal handyphone system (PHS). , PDA (Personal Digital Assistant), International Mobile Telecommunication (IMT) -2000, Code Division Multiple Access (CDMA) -2000, W-Code Division Multiple Access (W-CDMA), Wireless Broadband Internet (WBRO) terminal, smartphone ( All types of handheld based wireless communication devices such as smartphones, smartpads, tablet PCs, and the like may be included.

For example, a user of the mobile terminal 100 may be a viewer who wants to watch copyrighted dramas, entertainment programs, movies, etc. through an app such as YouTube, and the user may enter a search box of YouTube. It may be a user who searches for copyrighted content and transmits content request traffic to the data providing server 300 by clicking any one of the contents list output as a search result. In this case, the data providing server 300 may be a server providing all data including content.

The data providing server 300 may be a server providing all data including content, and may be, for example, a contents provider, a program provider, a service provider, or the like.

The content path bypass server 400 receives the traffic transmitted from the mobile terminal 100 to the data providing server 300, and if the content requested by the mobile terminal 100 to the data providing server 300 is blocked content, the mobile terminal 100. A block message may be sent to 100. In this case, the blocked content may be copyrighted broadcasts, movies, music, or the like, or may be violent or harmful content.

The content path bypass server 400 may inspect all traffic searched through the app in the mobile terminal 100, and classify traffic requesting content such as a video or music among all traffic. Then, by analyzing the content request traffic, it is possible to analyze the type of mobile terminal 100, the address where the content is present, and determine whether the content corresponds to the blocked content.

The content path bypass server 400 may transmit a blocking message to the mobile terminal 100 when the corresponding content is blocked content. At this time, when the mobile terminal 100 attempts to access the data providing server 300 through the blocking message, the mobile terminal 100 may bypass the content path bypass server 400 to stream an image including a warning message to the mobile terminal 100. .

In this case, when an alert message is transmitted from an existing web-based browser, the notification is transmitted based on HTML or an alert message is transmitted. Therefore, when the copyright-related content is streamed from the mobile terminal 100 based on an app However, a problem may occur in which the corresponding warning message cannot be received.

Accordingly, the content path bypass server 400 according to an embodiment of the present invention proposes an HTTP-based technology so that an app (App) receiving video streaming can view a corresponding warning message.

Through this, the mobile terminal 100 may be blocked from the step of searching for and clicking the blocked content, and searches the data providing server 300 one by one to make copyright related or harmful content without having to report a copyright or a harmful report. You can stop it. Therefore, the content path bypass server 400 can prevent the supply of copyrighted content and harmful content by using the market principle that supply is also reduced when demand decreases by blocking the demand itself rather than supply.

FIG. 2 is a diagram illustrating the content path bypass server illustrated in FIG. 1. 1 and 2, the content path bypass server 400 includes a collector 410, a receiver 420, a classifier 430, an analyzer 440, a path bypass 450, and a notification unit ( 460 and a transmitter 470.

The collector 410 may collect traffic of the mobile terminal 100. In addition, the collection unit 410 may be installed separately from the content path bypass server 400. For example, the collection unit 410 may be separated from the content path bypass server 400 and installed in, for example, router equipment or switching equipment.

 In this case, there may be two methods for recognizing the content request of the mobile terminal 100. One is a method of copying and collecting all the packets of the mobile terminal 100, the other is a method of intercepting and collecting the packets of the mobile terminal 100 in the middle.

In order to use a method of copying and collecting all the packets of the mobile terminal 100, which is the former method, the collecting unit 410 may use mirroring or tapping to receive traffic of the mobile terminal 100. It may be provided as a device.

In this case, when the TAP device is installed in a specific line of the Internet section, it is possible to copy an IP packet using the Internet, and if the port mirroring function of the switching device is used, the IP packet is identical to the TAP device. You can copy it.

The TAP device may be installed in a line connected between equipment such as a router or a switch, and may provide a function of copying a packet circulated from the mobile terminal 100 to the data providing server 300. In this case, the content path bypass server 400 may receive all traffic of the mobile terminal 100 through a TAP device or mirroring.

In order to use the latter method, a method of intercepting and collecting the packet of the mobile terminal 100 in the middle, the collecting unit 410 is a DPI (Deep) to bypass the traffic of the mobile terminal 100 to the receiving unit 420 It may be provided as a packet inspection (PBR) or policy-based routing (PBR) device. In this case, the PBR device may be used as a function in equipment such as a router or a switch.

The DPI device may recognize a video service based on a signature. For example, it is possible to block or control only videos of YouTube. Accordingly, the DPI device may apply a technique of diverting the video request packet to the server using the video service recognition function.

The PBR device may bypass a packet destined for a specific destination or a service using a specific port from the router or the switching device to the content path bypass server 400. Assuming a particular port is HTTP = TCP: 80, all HTTP (TCP: 80) packets can be forwarded to the content path bypass server 400. Alternatively, for example, the L7 switch may selectively bypass only video request traffic to the content path bypass server 400.

In the former method, the original request packet is normally delivered to the data providing server 300 through the network 200, and the copy is delivered to the content path bypass server 400, so that a packet that is not a video request or a target of blocked content is not included. You do not need to take any action on the packet.

On the other hand, in the latter method, since the original request packet is not delivered to the data providing server 300 but to the content path bypass server 400, the packet is not the video request or the packet is not the target of the blocked content. It is necessary to transfer from the bypass server 400 to the data providing server 300.

The receiver 420 receives the traffic transmitted from the mobile terminal 100 to the data providing server 300. For example, when the collecting unit 410 is provided separately from the content path bypass server 400, the traffic of the mobile terminal 100 collected by the collecting unit 410 may be received by the receiving unit 420.

The classifier 430 classifies the content request traffic from the traffic. For example, the traffic may vary from traffic for Internet search, traffic for Internet games, traffic for music playback, traffic for content requests, and the like. At this time, the classifier 430 may classify only the traffic requesting the content from a variety of traffic.

That is, the classifier 430 may classify whether the video request packet is HTTP or RTSP by checking a payload included in the request packet. For example, a video request packet may be classified by analyzing a request address (URL) of a payload such as http://www.youtube.com/videoplaypack=xxxx.

The analyzer 440 may analyze whether the blocked content is requested by the mobile terminal 100 through the content request traffic. That is, the analysis unit 440 may analyze the content request traffic classified by the classification unit 430 to classify blocked content such as copyright violation content, violent content, adult content, and the like.

In this case, the criteria for classifying the blocked content may be received from a separate content management database (not shown), and the content management database may be analyzed through a report of a user or an in-house management staff, or a video automatic analysis system may be established. Can be applied.

The analyzer 440 may analyze using different addresses (URLs) in the app and the browser for the same content. For example, when using the SHORT URL used by the SNS, a large number of URLs may point to one image, and conversely, even if the video request URL is the same, the original content may be changed.

Therefore, the analysis unit 400 should be able to recognize that the same content may be the same even if the URLs are different or that the same content may be the same even if the URLs are the same. For this purpose, the URLs are different by using a hash value. Even if the same content or the URL is the same, it can be recognized that different content.

That is, the analysis unit 400 outputs a hash value by analyzing an address (URL) of the blocked content, analyzes content request traffic, outputs a hash value among the addresses of content requested by the mobile terminal, and blocks the content address. It is possible to analyze whether the content is the same by comparing the hash value of and the hash value of the requested content address.

For example, a response packet for a video request is used to maintain a hash value for the first portion of the content (512 Kbytes). Accordingly, by comparing hash values of contents provided through different URLs, when the hash values are the same, the same content may be determined. In this case, when the content is changed even though the same address is used, the same hash value may be used.

In this case, the hash value may be replaced with at least one of an ID, a format, a size, a playback time, and a change date of the content included in the content request and response. Alternatively, it is possible to periodically check for changes to the content.

In addition, as a result of the analysis of the analysis unit 440, if the request content of the mobile terminal 100 is not a predetermined block content, the transmission unit 470 for transmitting the traffic of the mobile terminal 100 to the data providing server 300 It may be further provided. That is, when the DPI unit or the PBR device is used in the collecting unit 410, all packets from the mobile terminal 100 to the data providing server 300 are intercepted by the collecting unit 410 and moved to the data providing server 300. Since no request of the terminal 100 is received, in the case of normal request traffic, the terminal 100 transmits data to the data providing server 300 again.

The path bypass unit 450 may transmit a blocking message to the mobile terminal 100 if the content requested by the mobile terminal is blocked content. In this case, the blocking message may be a redirection message. In addition, the blocking message may be matched with the known content. For example, the notification content may specify that the content requested by the mobile terminal 100 is illegal copyright infringing content or may be a video content called harmful content, and the blocking message may be a redirection message when the blocking message is received by the mobile terminal 100. The request message may be automatically transmitted to the address included in the redirection message, thereby reproducing the announcement image. In this case, the blocking message may be delivered to the mobile terminal 100 using a separate network interface.

In this case, the route bypass unit 450 may change the source IP address of the redirection message to the IP address of the data providing server 300. That is, the source IP address of the redirection packet must be changed and transmitted in the same manner as the destination IP address initially requested by the mobile terminal 100, so that the mobile terminal 100 can normally perform the redirection. Accordingly, the redirection message may use a message defined in the HTTP or RTSP standard, and thus, the mobile terminal 100 may enable redirection without changing a program or an app.

If the notification unit 460 receives the reconnection request traffic from the mobile terminal 100 to the data providing server 300 through the blocking message, the notification unit 460 may cause the notification content to be streamed to the mobile terminal 100. In this case, the notification unit 460 may be provided as a separate server from the content path bypass server 400.

In this case, the known content, which is a known image or a warning image, may be transmitted only once to the mobile terminal 100 or continuously. In the former case, only the first access based on the IP address of the mobile terminal 100 may be used. It is also possible to redirect to the known content. That is, the IP address for viewing the known content may be recorded so that a terminal connected to the same IP afterwards may not be redirected to the known content.

In this case, however, when the mobile terminal 100 accesses another IP address without using the previous IP address, the mobile terminal 100 may be redirected to the known content again to view the same known content repeatedly. In order to interwork with an authentication system, such as RADIUS, it is possible to manage the presence or absence of viewing of the public announcement video for each subscriber. In this case, the authentication system manages the subscriber ID and manages the presence or absence of viewing content using the ID regardless of the IP address change, where the ID may be, for example, a serial number or a phone number of the smart terminal.

In this case, it may occur that the well-known content cannot be played normally depending on the type of browser or app used by the mobile terminal 100. For example, because a new app is continuously updated, it may not be possible to watch the announcement content through redirection in a specific app.

Therefore, the announcement unit 460 may store a combination of a terminal and an application that can play the well-known content, and transmit a well-known content when the terminal and the application that the well-known content can be played. That is, the notification unit 460 may be driven by managing a list of recognizable terminals and apps and notifying only through an app that enables viewing of known contents.

Accordingly, by setting a combination of a terminal and an app that can play the announcement content in advance and managing the combination of the terminal and the app, and when viewing the blocked content in the terminal and the app that can be announced, by providing a redirect to the known content, It is possible to prevent the phenomenon of not watching a known image.

In addition, the notification unit 460 may transmit a known content having a format, a codec, and a resolution matching the type of the terminal and the player. In this case, the notification unit 460 may have a different format (flv, mp4, avi, etc.) of the playable image according to the type of the mobile terminal 100 or the video player of the mobile terminal 100, and the codec and resolution may also vary. .

Accordingly, the redirection message may be transmitted to recognize each mobile terminal 100 and to recognize a codec of the requested content so that an image suitable for each mobile terminal 100 is displayed. Referring to Table 1 below, the user-agent is ipad 2, the host is m.ustream.tv, and the content-type is video / mp4. Referring to Table 2, when requesting YouTube content from a MacBook There is a Macintosh in the user-agent field of the request packet; The terminal may be recognized in the form of intel Mac OS X 10_7_4. Referring to Table 3, a video format called flv may be recognized in the form of Content-Type: video / x-flv of a response packet. For example, the iPhone 4 can redirect to 960 * 640 MP4 files, while the iPad 2 can redirect to 2048 * 1526 MP4 files.

Figure 112012080787108-pat00003

As a result, when the mobile terminal 100 receives the redirection message, the mobile terminal 100 automatically re-requests the redirection video according to the standard, and the mobile terminal 100 is not the original video, but the content path bypass server. You will be viewing the known content redirected by 400. Therefore, the present invention can fundamentally block the revenue of the suppliers distributing the content by eliminating the number of clicks on the illegal content, that is, the demand, and fundamentally eliminate the source distributing the illegal content.
