The application execution unit 4030 may be loaded with a security authentication application such as a PG application required for the T-commerce system and an e-mail application requiring security such as user authentication.

Hereinafter, as a method of performing security authentication in a tee-commerce system, an electronic payment method and a user authentication method will be described with reference to the accompanying drawings.

The above-described user authentication management server and security server are embodiments of a server that performs security authentication used to provide payment, e-mail, and various other services for electronic commerce in a communication environment, which may be referred to as a security authentication server hereinafter. .

5 is a diagram illustrating an electronic payment method in the tee-commerce system according to an embodiment of the present invention.

When the user inputs a service or product purchase request to the receiving terminal, the receiving terminal may request the request to the ubiquitous server (S5010). With reference to FIG. 5, the user's request will explain the product purchase request as an example.

The ubiquitous server parses the purchase information of the product purchase page received from an external server or CP (Content Provider), encodes it, and transmits the encoded information to the flexible browser of the receiving terminal (S5020). The ubiquitous server detects whether payment related information exists in the product purchase page, and if payment related information is found, encodes the purchase related information to the receiving terminal, and when the user executes payment on the encoded page, the electronic payment program is executed. Can be executed.

When the user proceeds to purchase (S5030), the receiving terminal executes the electronic payment program required for purchasing the product (S5040), and as an embodiment, the electronic payment program may be an electronic payment module of PG.

When the user inputs the payment information after the electronic payment program is executed (S5050), the input payment information is transmitted to the ubiquitous server through the flexible browser, and the ubiquitous server transmits the payment information to the user authentication management server (S5060).

The user authentication management server performs user authentication through the received payment information (S5070), and if the user is authenticated as a result of the authentication, executes a product purchase using the electronic payment program (S5080). If the authentication is not an authenticated user or the authentication is not properly performed, the process may return to the step of inputting user information.

When proceeding to purchase a product, the ubiquitous server may deliver the authenticated payment information to the CP (S5090). When the purchase of the product is completed according to the authenticated payment information, the ubiquitous server receives the payment completion page from the CP, encodes the received payment completion page, and transmits the received payment page to the receiving terminal (S5100).

FIG. 6 is a diagram illustrating an electronic payment method in a tee-commerce system according to another embodiment of the present invention.

When the user requests the execution of the application to the ubiquitous server through the receiving terminal (S6010), the ubiquitous server may transmit the execution command of the application to the security server (S6020). In this case, the application program may include an electronic payment program, an e-mail program (eg, Outlook) that requires security authentication, a private program (eg, a computer remote control program, and the like).

When the application program execution command is transmitted to the security server, the security server executes a user information input program and transmits it to the ubiquitous server, and the ubiquitous server encodes the received user information input screen and transmits it to the receiving terminal (S6030).

When the user inputs user information (S6040), the ubiquitous server transmits the user information received from the receiving terminal to the user authentication management server (S6050). The user authentication management server may determine whether the user who wants to execute the current application program is an authenticated user based on the received user information (S6060).

In the case of an authenticated user, the application server is executed in the security server, and the ubiquitous server may encode the execution screen and transmit the encoded application screen to the receiving terminal (S6070).

The aforementioned electronic payment program, e-mail program, computer remote control program, and application of a security server are various applications that perform various authentications required for electronic commerce or require user authentication in a communication environment. May be referred to as a program.

As described above, the ubiquitous server encodes an application program, such as a user information input program and a security authentication application, received from the security server and transmits the encoded application program to the receiving terminal. At this time, the ubiquitous server performs encoding so that the application program cannot be processed or the processing of the application program is delayed according to the receiving terminal and the transmission / reception protocol.

Hereinafter, an encoding method of a ubiquitous server will be described.

When the A / V (Audio / Video) linked service is configured for content encoding, a content encoding method using an alpha value for reducing network usage is possible.

In the media where other service applications are displayed while the video areas of IPTV, DMB, and A / V are displayed, an alpha value that sets the transparency of the graphic source to perform redundant display processing on the A / V video area and the service application area. Can be processed. Normally, an alpha value is added to the RGB value of a graphic source to convey four Int signals. However, in most cases, the alpha value is fixed in one medium. By using this feature, it is possible to set the alpha value at the client, pass only RGB value of graphic source to network, and reduce 1/4 of network usage by not sending alpha value.

In order to implement this, when a service terminal requests service content when A / V is provided, a specific value is also requested and an alpha value is transmitted. It is possible to configure a method of transmitting an alpha value together when requesting a specific value.

7 is a diagram illustrating a content encoding method of a ubiquitous server according to an embodiment of the present invention.

In FIG. 7, an area defined by the border 125 displays a screen of service content. The service content is composed of a UI (User Interface) displayed translucently on the A / V. If the ubiquitous server delivers the alpha value that handles the translucency when encoding the content, the alpha value should be specified for the RGB pixel for the area according to the UI screen composition. However, since the alpha value is usually specified in the overall service configuration, the alpha value can be defined and used in the flexible browser and the content itself.

On the other hand, as an encoding method for the changed response information, The screen and the elements can be divided by a specified number to retransmit the changed area.

Although the data to be transmitted may be compressed and transmitted, most receiving terminals support low-end hardware, so it is necessary to restore the received compressed file to provide a service. At this time, since the time taken to restore may interfere with the service, a compression method that is easy to decode such as non length compression may be preferable instead of an excessive compression method.

Partial data that can be retransmitted includes images, text, and compiled class files that each service can additionally use.

8 is a diagram illustrating an embodiment of encoding a response information to be changed as a method of encoding a content of a ubiquitous server according to an embodiment of the present invention.

That is, in the example of FIG. 8, retransmission is performed only for regions 1-2 and 2-2 where information is changed.

In addition, the component that is fixed and the part that operates on a predictable schedule does not continuously transmit the changed part in the server, but the component that changes the part after the client receives it by transmitting the component including the changed part. Can be processed, and thus the efficiency of the network can be increased.

FIG. 9 is a diagram illustrating an example of encoding a response information of a fixed region as a method of encoding a content of a ubiquitous server according to an embodiment of the present invention.

The example shown in FIG. 9 is to schedule a change of a specific area of the web content, for example, the flash advertisement area 126, transmit each component in its entirety, and then reconfigure and schedule the display at the receiving terminal. .

On the other hand, as an example of a method of encoding response information for a fixed area, in the case of a service having a static screen configuration in an embodiment of a broadcast medium, an entire background screen called a background may be Iframed and transmitted. The background Iframe is encoded in advance and ready for transmission.

The advantage of using Iframe is that hardware decoding is displayed and can reduce CPU processing load. In addition, when the resolution of 720x480 is encoded, 800 KB of screen information is usually obtained. When converted to Iframe, it is reduced to 50KB, so that the compression effect of the transmission contents can be obtained.

By encoding and transmitting frame by frame, the content decoding and screen processing of the receiving device is greatly reduced, so that the system efficiency of the receiving device is significantly increased, and in particular, the processing time can be greatly reduced in the case of a screen such as a URL used on the Internet. have. In addition, even when a delay occurs in the transmission and reception process, since the screen is received in units of frames, no blank of the screen occurs, and thus the screen can be output without interruption. In addition, since image information in frame units and coordinate information generated during encoding are transmitted, only the changed portion of the image information may be retransmitted according to the coordinate information, or a user input input to a specific coordinate portion may be received.

That is, the background of the service screen is transmitted, and the information to be changed displayed on the background is displayed. In this case, the information may be text, compiled application data, or the like.

When the ubiquitous server receives the security authentication program from the security authentication server, the ubiquitous server may transmit the security authentication program encoded in units of frames by the above-described encoding scheme without transmitting the security authentication program to the receiving terminal. In this case, the ubiquitous server may encode and transmit coordinate information about the frame-based image and the frame-based image and the security authentication information about the security authentication program.

The digital broadcast receiver may decode the encoded security authentication program through the flexible browser and display it on the screen. The digital broadcast receiver displays an image in units of decoded frames on the screen, arranges images using the decoded coordinate information, converts and displays received images, or receives user input through an image portion of a specific coordinate. Can be. In addition, the digital broadcast receiver may execute the decoded security authentication program or process the security authentication information received from the user through a security authentication processing unit included in the flexible browser.

By encoding the security authentication program in the above-described manner and transmitting it to the receiving terminal, the ubiquitous server of the present invention enables security authentication with various security authentication servers at the receiving terminal even when the communication protocols are different.

Therefore, there is an effect that the receiving terminal can conveniently use various paid services using different communication protocols.
