Abstract: The present invention provides a file synchronization and centralization system and a file synchronization and centralization method, which forcibly transmit, to a central server, data corresponding to a synchronization condition, among data being operated or data having been operated, and deletes the transmitted data from a PC, thereby making it impossible to transfer the data (including files and documents) to the outside or completely blocking a route through which the data can be attacked by ransom ware. The file synchronization and centralization system includes a central server and a PC.

Abstract: The illegal content searching system and the searching method thereof according to the present invention detect illegally distributed contents, such as webtoons, sound sources, books, and videos including web information which uses a modified keyword, to protect the copyright holder and teenagers. The illegal content searching system of the present invention includes a crawling server which searches a plurality of websites to detect the illegal contents which are illegally copied and distributed from a plurality of websites.

Abstract: The present invention relates to a cloud-based secure printing system and a method of processing same. When requesting printing of a desired printed matter by using a communication network of a mobile terminal of a user and a personal computer, the cloud-based secure printing system of the present invention uses a print management server and a print agent to authenticate and confirm the user and document security authority, and prints the printed matter through a desired printer. According to the present invention, the effects of strengthening the security of printed matter, increasing user convenience and work efficiency through a mobile printing function, and reducing the printing of unnecessary documents and the leaving of documents unattended and reducing costs can be obtained, and a secure print platform can be provided which is capable of printing, regardless of which printer manufacturer and model is used.

Abstract: The present invention provides a system and a method of preventing intrusion of a malicious code based on a smart device. The system for preventing intrusion of a malicious code based on a smart device includes: a collection unit that collects at least one situation information allowing for recognition of situation of the smart device; a control unit that primarily determines whether to execute an application on the basis of the collected situation information and secondarily determines whether to execute the application on the basis of a hash value extracted from a portion of or the entire file relating to execution of the application; and a display unit that displays an image for executing the application on the basis of the result of determination, in which the control unit checks whether the application performs a function of a predetermined malicious code on the basis of the collected situation information and primarily determines whether to execute the application on the basis of the result of checking.

Abstract: Disclosed are a method and an apparatus for rendering outlines of multimedia character images for rendering the outlines. The method consists of: (a) detecting parameter values that include a screen width, a two-dimensional screen point, a three-dimensional view point, and a field of view on both ends of the screen width from a position of a user, which are associated with the character to be displayed on the screen from the driven multimedia contents; (b) calculating positional information on an x-axis direction of the character for a two-dimensional screen, on which the character is displayed, based on the parameter values; (c) calculating outline thickness factor of the character in three dimensions, based on the positional information of the x-axis direction of the character on the two-dimensional screen; and (d) performing and processing an outline rendering on the character based on the calculated outline thickness.

Abstract: Disclosed is a method for capturing a directX moving picture. The method consists of (a) allowing the control unit to generate a multisampled rendertarget surface of a moving picture using an anti-aliasing technique for a capturing target moving picture of the directX multimedia contents in a buffer; (b) allowing the control unit to detect the capturing target moving picture using the anti-aliasing technique, which is provided in a back-buffer by executing the directX multimedia contents and copy and temporarily store the detected capturing target moving picture to and in the multisampled rendertarget surface; (c) allowing the control unit to output the temporarily stored capturing target moving picture on the basis of an FIFO method when the capturing target moving picture is stored in the multisampled rendertarget surface at a reference value or higher; and (d) allowing the control unit to convert and store the output capturing target moving picture.

Abstract: Disclosed is a method for authentication of a game executing authority. The invention is implemented by steps of requesting a transmission of a decoding key for decoding a coded execution file for executing a game to an authentication server; decoding the coded execution file by the decoding key received from the authentication server to generate the execution file; hashing an obtained present time and a random data together to generate hashed data; encrypting the present time, the random data, and the hashed data by any fixing key to generate the coded data; transmitting the generated coded data as a parameter to the execution file; and confirming whether a hashed value obtained by hashing the present time and the random data, which are obtained by decoding the coded data by the fixing key, matches the hashed data.
