(Roll Back, the act of returning to the existing data when the current data is invalid or corrupted) can be performed. Here, all information managed by the management server 200 may be stored in the file system of the management server 200 .

The storage management system may collect information managed by the management server 200 by date, build a file system in which it is stored in one folder, and arrange and manage each folder by date.

The storage management system may randomly select any one of the plurality of folders and determine whether a ransomware-infected file exists in the corresponding folder.

First, the storage management system may acquire a plurality of images including file names and icons of files included in the corresponding folder by opening the selected folder for a predetermined period. The storage management system may measure the similarity between a plurality of images, and determine whether a ransomware-infected file exists in the corresponding folder based on the similarity. For example, the degree of similarity may be calculated by extracting feature points (eg, shape, texture, brightness, boundary, etc.) of each image and comparing them.

Meanwhile, the education solution system 1000 according to an embodiment of the present invention may further include an update evaluation system.

The update evaluation system may evaluate the update necessity for the site built by the management server 200 and deliver it to the system administrator of the management server 200 .

The update evaluation system can acquire a plurality of screenshot images of the learner terminal 300 and the manager terminal 100 while accessing the site provided by the management server 200 from the learner terminal 300 or the manager terminal 100 have.

The update evaluation system may group the plurality of screenshot images by the same page by comparing the plurality of screen shot images and checking whether there is a change in successive images. That is, if there is no change in successive screen shot images, the same screen will be output through the learner terminal 300 and the manager terminal 100 .

The update evaluation system may calculate the number of screen shot images included in each group, and may list each group in the order of the number of images. The update evaluation system may pre-store a reference image for each page of the site provided by the management server 200, compare the screen shot images of each group, and determine which page each group corresponds to.

The update evaluation system may transmit to the system administrator of the management server 200 so that the update evaluation of the page corresponding to the highest group may be considered preferentially.

As such, the education solution system 1000 may be implemented in the form of program instructions that can be executed through various computer components and recorded in a computer-readable recording medium. The computer-readable recording medium may include program instructions, data files, data structures, etc. alone or in combination.

The program instructions recorded on the computer-readable recording medium are specially designed and configured for the present invention, and may be known and available to those skilled in the computer software field.

Examples of the computer-readable recording medium include a hard disk, a magnetic medium such as a floppy disk and a magnetic tape, an optical recording medium such as a CD-ROM and DVD, and a magneto-optical medium such as a floppy disk. media), and hardware devices specially configured to store and execute program instructions, such as ROM, RAM, flash memory, and the like.

Examples of program instructions include not only machine language codes such as those generated by a compiler, but also high-level language codes that can be executed by a computer using an interpreter or the like. The hardware device may be configured to operate as one or more software modules to perform processing according to the present invention, and vice versa.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those of ordinary skill in the art to which the present invention pertains can realize that the present invention can be embodied in other specific forms without changing its technical spirit or essential features. you will be able to understand Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
