Abstract

The invention relates to a method for transmitting data on a common medium between a center (133) and a plurality of subscribers (130, 131, 132), which is controlled by sending data packets for the center (133) to the subscribers (130, 131, 132) (downlink) and from the subscribers (130, 131, 132) to the center (133) (uplink). Downlink and uplink signaling data phases (2, 5; 30, 31; 40, 43, 45; 50, 53, 55, 57) are provided in signaling periods (1) of variable lengths in addition to user signal data phases (3, 4; 41, 42, 44, 46; 51, 52, 54, 56, 58). Said signaling data is used to organize uplink (10) and downlink (9) data transmission by transferring send request and allocating send time and optionally other information. Signaling data for subsequent data phases (42-46; 52-58) is contained in a downlink signaling data phase (9). Said subsequent data phases only begin after an intermediate data phase (41; 51), whereby the intermediate data phase is organized with an earlier downlink signaling data phase and is enhanced in terms of flexibility and dynamics by flexibly positioning the signaling data phases (30, 31, 5; 40, 43, 45; 50, 53, 55, 57) within a signaling period and by determining at least one preceding downlink signaling data phase and by activating a user signal data phase (44, 56) between an uplink signaling data phase (43, 55) and a downlink signaling data phase (45, 57).

Description

On-line verified test} Method of transmitting answers with realtime

The present invention relates to a method for conducting an online test using a computer network, and more particularly, to an online certification test answer real-time transmission method that can authenticate whether a candidate is a valid candidate during an online test.

In recent years, the Internet is widely used, which consists of a number of computers and computer networks connected through communication links. Interconnected computers can exchange information using a variety of services such as e-mail, gopher, FTP, and the World Wide Web, where the server computer system (ie, web server) The web page information is sent to a remote client system. Each resource on the web (that is, a computer or web page) is given a unique uniform resource locator (URL), and in order to view a particular web page, the client system designates the URL of that web page and transmits it according to the HTTP protocol. If so, the server system sends corresponding web page information correspondingly. When the client system receives the web page, the client system typically displays it on the monitor through a browser.

Meanwhile, various services such as cyber distribution services (e-commerce and auction), cyber financial services (securities and banking), and cyber education services are provided using the Internet. In the conventional online test method using the Internet, candidates are distributed. The correct answer for the real-time test questions at the location.

However, the real-time test on the Internet as described above because there was no way to authenticate whether the candidate who entered the answer is the same as the candidate recorded on the answer sheet, there is a problem that the certified test is impossible. Therefore, the conventional online test using a network is to collect candidates in a certain place where they can be monitored and to submit a problem, which is provided by paper, online, by using a computer. Accredited testing was not possible.

In order to solve the problems described above, the present invention randomly photographs the candidate during the test after installing an image camera and the like and transmits the online certification test answer real-time to authenticate the candidate by transmitting the test answer data in real time. The purpose is to provide a method.

In order to achieve the above object, the present invention includes a test method using an online test server and a test terminal connected through a network, comprising: a first step of inputting a candidate's personal information; Transmitting a candidate's personal information when the online test starts; A third step in which the answer author writes the answer to the online problem; A fourth step of the video camera randomly capturing the answer author according to the random signal generated by the online test program; A fifth step of transmitting the image data and the answer data in real time if there is captured image data, and transmitting the answer data in real time if there is no captured image data; And repeating from the third step if not the end time of the test, and ending the sixth step when the end time of the test is reached.

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

1 is a diagram illustrating a network configuration for an online test authentication method according to the present invention. Referring to FIG. 1, a plurality of test terminals 100 are connected to an online test server 120, and each test terminal 100 is a normal personal computer (PC), video cameras 106a and 106b and a scanner ( 102a, 102b, etc. are connected. The online test server 120 provides test questions in real time, receives answer data, evaluates test results, and prints test answers. The test terminal 100 temporarily stores the candidate's personal information or answers using a keyboard, and then stores the information temporarily. Then, the test terminal 100 is connected to the online test server through the network 110 together with the testee's image information captured by the video cameras 106a and 106b. Forward to 120. When the candidate's examination table or resident registration card is scanned with the scanners 102a and 102b, the scanned data is transmitted to the online test server 120 through the network 110.

The network 110 may be any type of network, such as a local area network in a school, an intranet of an enterprise, or a public network such as the Internet. In particular, in the present invention, since the identity of the test taker can be confirmed by the image data during the online test, the substitute test is not possible, and thus, the certification test may be conducted in a distributed environment such as each home or company using the Internet.

2 is a diagram illustrating an online test certification concept according to the present invention. Referring to FIG. 2, the authentication answer data is transmitted to the online test server 120 by combining the answer data input by the user through the keyboard, the image data captured by the video camera, and the scan data scanned by using a scanner to scan a candidate table or identification card. This allows you to verify that you and the actual answer writer match. In this case, the video cameras 106a and 106b randomly capture (capture) the appearance of the answer maker during the test time, and then transmit image data together with the time information, so that the substitute test is impossible and thus the candidate's authenticity can be confirmed. For this purpose, the online test program has a fixed number of times from the test start time to the end time, but generates a random capture signal at the time of its occurrence and sends it to the video camera. Capture.

3 is a diagram illustrating a method for transmitting a real-time answer to an online certification test for transmitting an answer in real time according to the present invention. Referring to FIG. 3, a candidate taking an online test sits in front of a test terminal and waits for a test (301). First, when the test preparation time is reached, the candidate's name, address, resident registration number, etc. are input, and the candidate's personal information is input by scanning the resident registration card or the examination table (302,303).

Subsequently, when the test start time is reached, the candidate's personal information is transmitted to the online test server 120, and if the test start time is not provided, the test is waited (304, 305, 306). Subsequently, the candidate's personal information is transmitted and the real-time test questions provided by the online test server 120 are input and the test answers are input (307,308).

On the other hand, at the start of the test, a capture signal is randomly generated by the online test program and transmitted to the video camera. Accordingly, the video camera operates at random time to capture the candidate's image, and when the image data is obtained by the image, the answer is given. The data and the image data are directly transmitted to the online test server 120 (310, 311). If there is no captured image data, the input answer data is transmitted in real time (312).

Subsequently, the test procedure is repeated until the test end time, and then ends when the test end time is reached (313).

As described above, the present invention transmits the answer data in real time even during the test, thereby reducing the burden on the online test server generated by transmitting the data at the end of the test.

The online test server 120 stores test taker information, scan data, test answer data, and image data on the database when the test answer data is received, and outputs it in the form of an answer sheet as shown in FIG. 4 when necessary. View through screen or print through printer.

Referring to FIG. 4, the personal information and the scanned ID card or the examination table are displayed at the top of the answer sheet, the answer data input by the candidate is displayed along with the question number, and the image data is displayed on the right side together with the captured time information. According to the exam answers, you can check whether the candidate's personal information matches the actual answer writer so that they can take the certified test even in a distributed environment such as the Internet.

As described above, according to the present invention, it is possible to confirm whether the answer writer and the candidate coincide in the online test, which is impossible to supervise the candidate by photographing the answer writer at random during the online exam and transmitting the answer with the answer data. There is this. Therefore, when the method of the present invention is applied to various test systems, it is not necessary to gather to a designated place for the test, it is convenient for the candidate, and there is an advantage of reducing the cost required for the test because no test supervision is required.
