Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the same or corresponding components will be denoted by the same reference numerals regardless of the reference numerals and redundant description thereof will be omitted.

First, a configuration of a streaming service providing system according to an exemplary embodiment of the present invention will be described with reference to FIG. 1.

1 is a block diagram showing the configuration of a streaming service providing system according to an embodiment of the present invention.

As shown in FIG. 1, a streaming service providing system according to an exemplary embodiment of the present invention may include a client 100, a web server 120, and a streaming server 130.

Meanwhile, in FIG. 1, only one component is illustrated for convenience of description, but one or more components may be present.

First, the client 100 is a device that is connected through the communication network 110 to access the web server 120 and the streaming server 130 to receive streaming content.

The client 100 may include a web browser (not shown) for connecting to the web server 120 and the streaming server 130 and an application (not shown) necessary for playing the streaming content. It is apparent that the web browser and the application may be installed in the form of a program on the client 100.

The client 100 may be connected to the web server 120 and the streaming server 130 by having a communication function, and may install a program capable of playing the received streaming content, and output the streaming content to be played. There is no limitation as long as the device includes a display screen.

The client 100 may be, for example, a wireless terminal such as a user personal computer (PC), a mobile phone, a personal digital assistant (PDA), and the like, but is not limited thereto.

The client 100 is connected to the web server 120 and the streaming server 130 through the communication network 110, the communication network 110 in the present invention includes not only online and mobile communication network, but also online is TCP / IP Several services that exist at the protocol and its upper layers: Hyper Text Transfer Protocol (HTTP), Telnet, File Transfer Protocol (FTP), Domain Name System (DNS), Simple Mail Transfer Protocol (SMTP), and Simple Network Management Protocol. ), All open global network architectures that provide Network File Service (NFS), and more.

The mobile communication network also includes an access gateway that enables transmission and reception of wireless packet data in addition to a base station (BS), a mobile telephone switching office (MTSO), and a home location register (HLR). It further includes components such as a gateway, a packet data serving node (PDSN), and the like.

The web server 120 allows a user to input information necessary for authentication through the client 110, and provides a web document that provides information on streaming content.

In addition, the web server 120 according to the present invention may generate the first key required for providing the streaming service and transmit the generated first key information to the client 100.

The generation of the first key is performed by the web server 120 through a separate procedure after authentication by inputting an ID / password of the user through a web document provided by the web server 120. Alternatively, the first key may be generated by an authentication procedure using an ID / password of a user who has been input.

Meanwhile, in FIG. 1, the web server 120 is illustrated. However, the web server 120 includes the functions of the web server 120 in the streaming server 130 that provides the streaming content. If a separate web document is not provided in the streaming service providing system according to the present invention, the web server 120 may not be included.

On the other hand, the client 100 receives the first key information from the web server 120 generates a second key, the first key received from the web server 120 and the second key generated in the client 100 and The state check time information, which is time information to transmit the state information of the client 100 to the streaming server 130, is transmitted to the streaming server 130.

Such second key information may be generated using state check time information.

In addition, the status check time information is a parameter included in the web document when each component of the streaming content providing system according to the present invention is shared in advance, or when the web server 120 provides the web document to the client 100. It is also possible to transmit to the client 100, and to transmit it to the streaming server 130 from the client 100, or to transmit to the streaming server 120 from the web server 120.

On the other hand, in the above description has been illustrated as using two key information, such as the first key and the second key for more thorough authentication and security, it is obvious that only one such key information can be used.

In addition, a plurality of keys such as a first key and a second key may be generated in another device, and the client 100 may request an authentication by accessing the streaming server 130 using only this key information.

Meanwhile, the first key, the second key, and the state check time information may be transmitted to the streaming server 130 together with or separately from a request for streaming content from the client 100.

The streaming server 130 stores and transmits streaming content of a content provider (CP).

In addition, the streaming server 130 according to the present invention performs an authentication procedure using the first key and the second key received from the client 100.

In addition, the streaming server 130 determines whether the status information of the client 100 is received at the corresponding time according to the status check time information received from the client 100, and if the status information of the client is received at the corresponding time, the client From the state of 100, it is determined whether to provide streaming content.

Although not shown in FIG. 1, the streaming server 130 may be connected to a database in which streaming content is stored.

A method of providing a streaming service through authentication using key information and state check time information according to the present invention will be described in more detail with reference to FIGS. 2 and 3.

2 is a flowchart illustrating a sequence in which a streaming service is provided according to an exemplary embodiment of the present invention.

As shown in FIG. 2, the streaming service according to the present invention first requests authentication from the client 100 to the web server 120 (S200). The authentication request in the client 100 may be an authentication request through input of an ID and a password as described above.

When user authentication is processed according to the authentication request, the web server 120 generates a first key (S202) and transmits the generated first key information to the client 100 (S204).

The generation of the first key may be information generated using the processed user authentication information, but is not limited thereto.

Receiving the first key information, the client 100 generates a second key (S206), which is information on a time for transmitting the first and second keys and the status information of the client 100 to the streaming server 130. The state check time information is transmitted to the streaming server 130 (S208).

In FIG. 2, the first key, the second key, and state checking time information are all included and transmitted to the streaming server 130. However, as described above, the second key information may be generated using the state checking time information. have.

In addition, the state check time information may be shared by each component of the streaming content providing system according to the present invention, or may be included as a parameter included in the web document when the web server 120 provides the web document to the client. It is also possible to transmit to (100), to transmit it to the streaming server 130 from the client 100, or to transmit to the streaming server 120 from the web server 120.

In particular, in the case where the state check time information is set in advance and shared or the state check time information is transmitted from the web server 120 to the streaming server 130, the state check time information from the client 100 to the streaming server 130 in FIG. It is obvious that it may not transmit.

In addition, although two key information, such as a first key and a second key, are illustrated as being more thorough in authentication and security, only one or two or more such key information may be used.

In addition, it is illustrated that the client 100 transmits the status check time information to the streaming server 130 in order to advantageously identify the same client 100 and to use different time information for each type of the client 100. The check time information may be set in advance between the client 100 and the streaming server 130.

The streaming server receiving the first key, the second key and the state information of the client 100 first processes an authentication procedure using the first key and the second key (S210).

When the authentication is completed according to the processed authentication result, the streaming content is transmitted to the client 100 (S212).

Meanwhile, the client 100 plays the received streaming content, and transmits the status information of the client 100 to the streaming server 130 at the status check time according to the status check time information transmitted to the streaming server 130 in step 208. It transmits (S214).

The streaming server 130 receiving the status information of the client 100 checks whether the time at which the client 100 transmits the status information of the client 100 matches the status check time information received from the client 100 in step 208. The determination is made and the state information of the client 100 is checked (S216).

Although FIG. 2 illustrates that the client 200 receives status information while providing and providing streaming content, the status information of the client 100 is received by receiving status information of the client 100 before transmitting the streaming content. It is also possible to transmit streaming content when the preset criteria are met.

Meanwhile, a process of providing a streaming service by performing authentication using a first key, a second key, and state check time information will be described in more detail with reference to FIG. 3, which is illustrated based on the streaming server 130. .

3 is a flowchart illustrating an order in which streaming content is provided by the streaming server 130 according to an exemplary embodiment of the present invention.

As shown in FIG. 3, in order to provide streaming content in the streaming server 130, first, a first key, a second key, and state check time information are received from the client 100 (S300).

As described above, the first key is information generated by the web server 120 and received through the client 100, and the second key and state check time information are generated by the client 100 and received by the streaming server 130. The information may be, but is not limited thereto.

Such information may be encrypted by the client 100 and transmitted to the streaming server 130, and the streaming server 130 may decrypt the received information.

Meanwhile, the streaming server 130 determines whether the first key and the second key are valid to perform an authentication procedure for the first key and the second of the received first key, second key, and state check time information. (S302).

If at least one of the first key and the second key is invalid, the streaming content is not transmitted.

However, if the first key and the second key is valid, the streaming content is transmitted to the client 100 (S304).

In operation S306, it is determined whether the status information of the client 100 is received from the client 100 at the status checking time according to the status checking time information received during the streaming content transmission.

If the status information of the client 100 is not received from the client 100 at the status check time, the transmission of the streaming content is stopped.

However, when the status information of the client 100 is received from the client 100 at the status check time, it is determined whether the status information of the client 100 received from the client 100 is valid according to a preset criterion. (S308).

If it is valid according to a preset criterion for the state information of the client 100, the streaming content is transmitted (S310).

In FIG. 3, the state information of the client 100 is a reproduction of streaming content as an example of a preset criterion. However, the state information of the client 100 may be authenticated using a first key and a second key. The same client may be used to protect streaming content, such as information that may determine that the same client is receiving streaming content or information about recording or storing the streaming content in the client 100 even if the same client 100 is used. If there is information, there is no limit.

For example, a client included in the IP (Internet Protocol) address of the client 100 authenticated using key information such as the first key and the second key and the state information of the client 100 received at the state check time ( If the IP address of 100 is different, it is also possible to disable streaming content.

Protection of streaming content can be enhanced by performing multiple authentication procedures such as authentication using key information, authentication using status check time information, and authentication using status information of a client.

In addition, by receiving the status information of the client before or during the provision of the streaming content from the client 100, it is possible to prevent this if the streaming content is illegally transmitted or stored by a method such as URL interception.

Meanwhile, the method of providing a streaming service according to the present invention may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

Hereinafter, a configuration of an apparatus capable of providing a streaming service according to the present invention will be described with reference to FIG. 4.

4 is a block diagram showing the configuration of a streaming service providing apparatus for providing a streaming service according to an embodiment of the present invention.

As shown in FIG. 4, the apparatus for providing a streaming service according to an exemplary embodiment of the present invention includes a first key and a second key authenticator 400, a state check time authenticator 410, and a client state determiner 420. It may include.

The first key and the second key authenticator 400 processes the authentication procedure using the first key and the second key received from the client 100.

As described above, the first key may be generated by the web server 120 and received through the client 100, and the second key may be generated and received by the client 100, but is not limited thereto.

In addition, although two key information, such as a first key and a second key, are illustrated as being more thorough in authentication and security, it is obvious that one or two or more of these key information may be used.

If the authentication procedure in the key authentication unit 400 is not processed, the streaming content is not transmitted to the client 100. However, when the authentication is performed by the key authentication unit 400, the streaming content is provided or the status is checked. The time authenticator 410 performs the authentication process using the state check time and the authentication process using the state information of the client 100.

The state check time authenticator 410 determines whether the state information of the client 100 is received from the client 100 at the corresponding time according to the state check time information received from the client 100.

If the status information of the client 100 is not received from the client 100 at the status check time, the transmission of the streaming content is stopped.

However, when the status information of the client 100 is received from the client 100 at the status check time, the client status determination unit 420 according to the preset criteria for the status information of the client 100 received from the client 100. It is determined whether it is valid.

The client state determination unit 420 determines whether the state information of the client received from the client 400 is valid according to a preset criterion.

Determining whether the state of the client 100 is valid according to a preset criterion is, for example, when the state information of the received client 100 is the playback of the streaming content, it is currently transmitted from the originally authenticated client 100. It can be determined that the streaming content being played is being played back.

However, in the case of illegal use of streaming content such as the URL interception described above, for example, in the case of intercepting a URL including authentication information, a client 100 other than the actual authentication 100 is processed. Since the streaming content is played back, the streaming content is played from the client 100 that has been processed for the first time, and information cannot be received.

Therefore, even when the streaming content is illegally provided, recorded or stored by intercepting the URL including the authentication information, it can be prevented.

Meanwhile, although each component is illustrated in FIG. 4 by function, it is obvious that such a function may be performed according to a control signal generated by a controller included in a digital device such as the streaming server 130.

In addition, it is apparent that the streaming service providing apparatus according to the present invention may be implemented in a form in which a program in which the aforementioned streaming service providing method is implemented is installed in a digital device.

Preferred embodiments of the present invention described above are disclosed for purposes of illustration, and those skilled in the art will be able to make various modifications, changes, and additions within the spirit and scope of the present invention. Additions should be considered to be within the scope of the following claims.
