Abstract

The EWF (Enhanced Write Filter) function is used to compare the state of change of each structure file of the registered data with various data (advertisement data, billing data, user setting data, etc.) downloaded to the multimedia public terminal. By adding the storage command accordingly, by rebooting the system, unnecessary data (garbage data, temporary file, etc.) is deleted by the rebooting process, and only the data to which the storage command is added is registered to the registered data. It can be updated to prevent the slow operation of the system due to congestion of unnecessary data, and to prevent information leakage caused by previously unnecessary data even when an error occurs and the system is restored.

Method for data management function in multimedia public telecommunication terminal

The present invention relates to a data management method of a multimedia public terminal, and more particularly, to apply various data (advertisement data, billing data, user setting data, etc.) downloaded to a multimedia public terminal using an enhanced write filter (EWF) function. By controlling the state, the system can be prevented from slowing down due to the congestion of unnecessary data (garbage data, temporary files, etc.), and even when an error occurs and the system is restored. The present invention relates to a data management method of a multimedia public terminal for preventing information leakage caused by unnecessary data.

Rapid changes and developments in information and communication have provided innovative communication networks capable of high-speed Internet, and communication devices with various functions have been developed and provided to adapt to this information communication era.

In addition, a multimedia public terminal that provides various functions (telephone, internet, advertisement function, etc.) on the web base is also a terminal corresponding to the information communication era, and it is possible to use the public telephone function as in the prior art as well as accessing the Internet as in computer communication. And it is possible to send an e-mail, and by providing a variety of content, to provide more useful and faster information to customers.

Multimedia air terminals that provide these various functions are generated in the process of processing various data, or a large number of temporary files and garbage data occurs in the process of deleting a file after an unspecified user downloads, which reduces the performance of the system Results.

An example of a commonly used operating system (O / S) is Microsoft's Windows. In the past, temporary files and garbage data are stored in a certain area of the hard disk. Therefore, a user who uses Windows as an O / S user may use temporary files or files for a certain period of time in order to prevent performance degradation of the system. The work of removing the garbage data should be done.

In addition, in the case of a multimedia air terminal distributed in a plurality of unspecified regions, it is essential to mount a hard disk on which O / S and various programs and data are recorded in order to perform multimedia functions to be provided to a user.

However, according to the conventional multimedia public terminal, the following problem (s) occur.

In other words, in the case of a multimedia air terminal distributed in unspecified areas, the administrator of the terminal visits a place where the terminal is directly installed in order to remove various temporary files and garbage data generated from the multimedia air terminal in order to prevent performance degradation of the system. As a result, a lot of loss occurs in terms of manpower and time, and the terminal cannot be used in the data cleaning process, thus providing inconvenience to the user, resulting in a decrease in the reliability of the multimedia public terminal. .

In addition, when the previous user uses the multimedia function in the terminal and an error occurs in the terminal, various information input by the previous user may be exposed to the next user or the administrator in the process of restoring the terminal. There is no means to prevent activities such as leaking and using various information of the former user for the purpose. Moreover, if the previous user used the financial transaction service in the multimedia public terminal, the leakage of information about this has serious consequences.

Accordingly, the present invention is to solve such a problem (s), the object of the present invention is to manage the data using the EWF function without the need for the administrator to visit the multimedia public terminal installed in the unspecified multiple areas (billing) Data, advertising data, administrator's setting data, etc.) and unnecessary data (temporary files, garbage data, etc.) can be managed selectively to improve the reliability of the multimedia air terminal and reduce operating costs (time and manpower costs). The present invention provides a data management method of a multimedia public terminal.

And a temporary drive 114 in which advertisement data is stored, and a memory 115 that is a temporary storage medium.

In this case, the operating drive 113 is an explorer shell program for executing a desktop and a system tray, an application software which is a program for operating an advertisement and controlling a telephone function, and a multimedia air terminal 100. Operating System for overall control of the driver, Driver a Tool Program for recognizing and executing various drivers attached to the multimedia terminal 100, and unnecessary data in the system booting operation (garbage) EWF program (EWF component) for forcibly removing data, temporary data, etc.).

In addition, the temporary drive 114 is a billing for downloading and storing billing-related data of the user memory folder (User Memory Folder) that stores various data set by the administrator to perform the public telephone function, and the multimedia public terminal 100 A billing data folder and a download folder for downloading and storing advertisement information are included.

Referring to Figure 3 with respect to the operation of the present invention having such a configuration as follows.

First, the multimedia terminal 100 is stored in the download folder in the temporary drive 114 according to the execution of the application software (structure file for controlling the display order and display state of the advertisement information) in the operating drive 113 in the standby mode. The advertisement information is detected and a video advertisement is displayed on the display unit and the input unit 106 provided at a predetermined position. In the standby mode in which advertisement information is displayed, the user inputs an arbitrary function key (hereinafter, in the case of a touch screen, including touching a screen) installed on the display unit and the input unit 106 to receive content or to drive a web browser. If you want to use the Internet, or if you want to use the telephone service by holding the handset set 101, the video advertising immediately stops and switches to the corresponding service mode.

The telephone control unit 105 determines whether the remaining amount of coins and cards is equal to or greater than the unit currency amount that can be talked to. Connect to the telephone network or mobile service provider server.

〈Data Management Mode〉

The multimedia public terminal 100 may be advertised at a predetermined time from a remote management server, an advertiser server, or a content providing server connected through the communication line 200 or a request of a remote server or a request of the multimedia public terminal 100, or from time to time. Information, manager setting information, billing data, etc. are downloaded and stored in the corresponding area of the temporary drive 114. At this time, the downloaded various information is downloaded at the same time the information file and the structure file, the structure file includes a variety of information for operating the downloaded information file. For example, the structure file contains various information such as the display time and the order of the downloaded advertisement information, and the display time (or period).

On the other hand, when the administrator turns on the main power of the multimedia terminal 100, the power supply 112 converts the input power to the voltage level required by the multimedia terminal 100, the central control unit 110 and the telephone control unit The operating power and the sustain power are supplied to the 105, respectively. Accordingly, the multimedia terminal 100 is booted (S101), the explorer shell program installed in the operating drive 113 in the storage medium 111 enables the EWF program (S102). Accordingly, unnecessary files (garbage data, temporary files, etc.) generated in the previous work environment are automatically deleted during the booting process.

Thereafter, the EWF program is a structure file for each program (explorer shell program, application software, O / S, drivers and tools, EWF program, etc.) in the operating drive 113 and each data downloaded to the temporary drive 114 (administrator). The structure file of the configuration data, billing data, advertisement data, etc.) is compared to check whether the changed structure file exists (S103).

Here, if the new data (advertisement data, etc.) has not been downloaded from the remote advertiser server or the content providing server, or if the administrator does not set new data (administrator setting data or billing data, etc.), the operation drive 113 and Each structure file stored in the temporary drive 114 is kept in the same state. However, if new data (advertisement data, etc.) has been downloaded from a remote advertiser server or content providing server, or if the administrator has set new data (administrator setting data or billing data, etc.), the structure file is downloaded along with the new data. Since the stored state, each structure file stored in the operating drive 113 and the temporary drive 114 is to maintain a different state from each other. At this time, since the structure file contains various information such as the name, version, size, location folder, etc. of the file, it is possible to determine whether the structure file is identical by comparing the various information of the structure file.

Through this comparison process, the structure file is checked to determine whether a changed structure file exists (S104). If the changed structure file exists, the data corresponding to the changed structure file in the memory (or virtual recording area) 115 is determined. (Downloaded data or data changed by the administrator, etc.) are recorded in the memory (or the virtual recording area) 115 (S105). In other words, in order to prevent an error of updating a file or data that is already executed, data is read from the operating drive 113 when the data is read, but written to the memory (or the virtual recording area) 115 when new data is recorded. shall. Therefore, the EWF program writes the data stored in the temporary drive 114 to the memory (or virtual recording area) 115.

Thereafter, the EWF program adds a Commit command to data recorded in the memory (or virtual recording area) 115 (S106), and then reboots the system (S107). Here, the various data or files on which the storage command is recorded are not deleted when the system is booted even though they are recorded in the volatile memory, i.e., the memory (or virtual recording area) 115.

On the other hand, if the structure file is not changed in the above step S104 (or when a Comm command is added in the previous step), the EWF program is recorded in the memory (or virtual storage area) 115. The data to which the Comm command is added is distributed and applied to each area of the operating drive 113 (Explorer Shell Program, Application Software, O / S, Driver and Tool, EWF Program, etc.) (S108). It executes (S109). Therefore, the multimedia air terminal 100 performs normal operation while the changed advertisement data, the billing data, and the manager's setting data are applied to each area in the operating drive 113.

As described above, although the specific embodiment (s) have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiment (s), but should be defined by the claims below and equivalents thereof.

As a result, according to the data management method of the multimedia public terminal according to the present invention, the following advantage (s) occurs.

That is, when the system is booted using the EWF program, unnecessary data (garbage data, temporary files, etc.) generated by the previous operation are automatically deleted, thereby preventing the performance degradation of the system due to the accumulation of unnecessary data.

In addition, in order to delete unnecessary data, the administrator does not need to directly visit a multimedia public terminal distributed in an unspecified number of regions, and thus, a lot of benefits are generated in terms of manpower and time.

In addition, since the process of deleting unnecessary data is made one-time during the booting process of the system, the service of the multimedia public terminal can be continuously maintained.

In addition, even when the previous user uses the multimedia function in the terminal and the system is rebooted and restored after an error occurs in the terminal, various information input by the previous user are stored in the volatile memory and are automatically deleted during the reboot process. It is possible to prevent the leakage of various information input by the user in advance.
