Description

Time magnet e-learning system {TIME MAGNET E-LEARNING SYSTEM}

An embodiment of the present invention relates to a time magnet e-learning system.

Due to the development of information technology including the Internet, the dissemination of an Internet lecture system that is provided through the Internet by producing a video that could not be considered in the traditional method of education between a professor and a student, which is usually conducted offline, is being activated.

E-learning is representative, and e-learning is WBT (Web-based training), that is, web-based education and training. It is designed to provide training courses. This e-learning is emerging as an alternative that can solve the problem of private education expenses as information infrastructure spreads as the spread of high-speed communication networks expands.

E-learning students have the advantage of being able to watch the lectures they want regardless of time and place, wherever there is an internet environment, can freely adjust the course time, and the cost of the lecture is relatively low, but the learning effect is not significantly inferior to that received in traditional educational institutions. In addition, the initial cost of developing an online education site and uploading it to the Internet for e-learning online lecture providers is relatively lower than the cost required for offline classes.

Such an Internet lecture system is in the spotlight, and accordingly, technologies related to many types of Internet video lecture authoring tools are being developed. However, although e-learning content has the advantage of being able to provide education of the same quality to all people without temporal and spatial constraints through one production, on the contrary, there is a difficulty in re-producing the content in order to improve the quality.

In addition, due to the lack of sociality due to the nature of e-learning, the emotional exchange between people is cut off and it is difficult to expect high concentration for each learner because it is a learning method that studies alone. For this reason, it is difficult to learn closely between instructors and learners, and it is also difficult to share information and resources related to learning and education.

In addition, in order to solve this problem of e-learning, we are trying to introduce and supplement the learning method called social learning as an educational method using social media for e-learning. It is difficult to expect much.

The Q&A content record management unit 320 records the Q&A content input through the input interface unit 310, but records the recording time of the input Q&A content when recording the Q&A input content instead of in real time. By recording according to the current playback time of the e-learning video content, it is possible to form a timeline for the Q&A input in order according to the playback time of the e-learning video content. For example, as shown in FIG. 5, assuming that query content ① and query content ② are registered, even if the actual time at which query content ① is registered is earlier than the actual time at which query content ② is registered, ② Since the playback time of the e-learning video content with the registered query content No. ① is earlier than the playback time of the registered e-learning video content, the playback time of the query content ② and the query content ① can be recorded sequentially. In addition, even when different learners register at different times for the contents of questions ① and ②, the same e-learning video contents are collected on one timeline and recorded in a sorted state based on the playback time, so that other learners can be shared with As shown in FIG. 6 , on the web, a community for the corresponding e-learning video content can be formed through a timeline generated based on the playback time.

The Q&A content exposure management unit 330 exposes the Q&A input contents recorded through the Q&A contents record management unit 320 through e-learning video content and a timeline, and provides Q&A content to at least one of an administrator and an instructor. By giving the exposure limit function, only the input with limited exposure can be selectively exposed. Here, the Q&A content exposure limit function is a function that determines whether the Q&A content is exposed to all learners, exposed only to the queryer, or not to all learners. The ability for an authorized person to decide or select whether the query content (or query content) registered by the learner can be viewed by all other learners, set private so that all cannot be seen, or can be viewed only by the inquirer am. Due to this exposure limiting permission function, the response content (or response content) may also be fully exposed, partially exposed, or not exposed as in the exposure limit state.

The e-learning video content protection unit 400 is installed in the learner communication terminal 10, and provides digital digital lecture content to the learner communication terminal 10 through the e-learning video content reproduction unit 200, and It is possible to generate learner identification information in the form of a universal unique identifier by using a unique identifier of at least one of a graphic card, a central processing unit, and a main board, and allocate the generated learner identification information to the learner communication terminal 10 .

As shown in FIG. 7 , the e-learning image content protection unit 400 may be an independent browsing application running in the operating system. As an example, the e-learning video content protection unit 400 may have an API (Application Programming Interface) permission granted by the operating system to have reading and control rights to the storage, input device, output device, and communication device of the computing device.

The e-learning video content protection unit 400 may include at least one of an identifier generator 410 , a service authentication unit 420 , a database unit 430 , and a content protection unit 440 as shown in FIG. 8 . have.

The content protection unit 440 may limit the negative use of the user who violates the protection policy, and may create a record of the user's negative use.

The content protection unit 440 may perform content protection without real-time interworking with the authentication management unit 500 . That is, if the content protection unit 440 is provided with a protection policy from the authentication management unit 500 in advance, it can operate independently in the private learner communication terminal 10 based on the protection policy. Therefore, interworking with the authentication management unit 500 is not required for content protection, and a user's negative usage can be immediately detected and quickly responded to.

In one embodiment, when the e-learning video content protection unit 400 is installed, a basic protection policy may be set together, and in this case, the e-learning video contents protection unit 400 may perform content protection according to the basic protection policy. . After that, based on user authentication and detection by user, the authentication management unit 500 may establish a protection policy for each user, and the e-learning video content protection unit 400 receives a protection policy for each user from the authentication management unit 500 when receiving a protection policy for each user. Content protection can be performed on the basis of

The authentication management unit 500 may authenticate the learner and the e-learning image content protection unit 400 based on the learner identification information.

As shown in FIG. 9 , the authentication management unit 500 may include at least one of a threat event detection unit 510 and a learner threat level setting unit 520 .

The threat event detection unit 510 may detect whether a threat event has occurred by a learner based on each learner's access record and negative use record. The threat event detection unit 510 may detect whether a threat event has occurred by a user based on each learner's access record and negative use record, and based on each learner's access record and negative use record In this way, it can also detect whether the user has used a threat tool.

The learner threat level setting unit 520 detects whether the learner used the threat tool based on each learner's access record and negative use record, and sets the learner's threat level based on the learner's threat behavior, , it is possible to set different protection policies for learners according to the learner's threat level. For example, as shown in FIG. 10 , the learner threat level setting unit 520 may define and set threat events in advance, and some minor events among these threat events - for example, viewing HTML source by right-clicking the mouse, etc. can be set to threat level 1.

The learner threat level setting unit 520 may define a threat tool in advance, and set the execution of the threat tool to the threat level 2 . For example, such a threat tool may include a screen recording program or a hacking tool.

The learner's threat level setting unit 520 may set the threat level 3 based on a history of a user's previous threat action, occurrence of a threat event, and use of a threat tool. For example, if there is a history of executing a threat event in the past and the threat event is continuously generated more than a set number of times, the threat level 3 may be set. As another example, if there is a history of previously executing a threat tool and a new threat tool different from the previous threat tool is executed, the threat level 3 may be set.

The learner threat level setting unit 520 may set the user's threat level based on the user's threat behavior. For example, the user threat level setting unit 520 may set the level of the threat performed by the user as the user's threat level.

In this way, the learner threat level setting unit 520 can perform proactive and preventive content protection by differently setting the user's threat level according to the user's threat behavior and setting different protection policies for the user. For example, when the user's threat level is high, the type of content provided may be limited, or the user's protection policy may be set to a higher policy, so that the event or threat tool blocked by the content protection browser may be set more intensely.

Meanwhile, although it has been described herein that the learner threat level setting unit 520 of the authentication management unit 500 directly sets the user threat level, the present invention is not limited thereto. For example, the learner threat level setting unit 520 provides information about the user's threat level to the threat behavior analysis unit (not shown) of the e-learning image content protection unit 400, and the threat behavior analysis unit (not shown) is the learner The threat level setting unit 520 may also be implemented in a manner that performs at least some functions. To this end, the learner threat level setting unit 520 may include a threat event detection function and/or a threat tool detection function.

According to this embodiment, as time goes by, knowledge and information are accumulated with the information exchanged with each other to create content that grows by itself, and it is possible to learn for a long time by increasing the concentration in a fun way through the learning method through social, Self-learning is possible through natural discussion and learning between learners, and additional learning such as exchange of knowledge and skills and learning resources is possible.
