20140258717 | CLOUD APPLICATION INSTALLED IN CLIENT TERMINAL CONNECTED TO CLOUD SERVER - A cloud application system installed in a client terminal that is connected to a cloud server via a network, the cloud application system comprising: a first driver controlling module configured to display a list of folders of a relevant user in the cloud server by communicating with the cloud server; a second cloud driver controlling module configured to encrypt a file of the cloud server to store it as the encrypted security file when the file is stored in the client terminal. | 09-11-2014 |
20140320888 | Apparatus and Method for Securing Confidential Information of Printed Document in Cloud Computing Environment - The present invention provides a client terminal for receiving a cloud computing service from a cloud server that provides the cloud computing service. The client terminal includes a character string information extractor configured to extract character string information from document data requested to print in a printer that is connected to the client terminal, a confidential information detector configured to detect confidential information from the extracted character string information and a controller configured to prohibit printing of the document data including the character string of the detected confidential information or to mask at least one or more characters of the character string of the detected confidential information, with predetermined specific characters. | 10-30-2014 |
20140325605 | SYSTEM FOR STORAGE SECURITY OF CLOUD SERVER IN CLOUD COMPUTING ENVIRONMENT AND METHOD THEREOF - The present invention relates to an apparatus for providing storage security of a cloud server in a cloud computing environment in which a client terminal is connected to the cloud server over a communication network. The apparatus includes a monitor configured to monitor which file data is requested for writing or transferring among file data stored in a storage of the cloud server and a controller configured to detect whether the file data monitored by the monitor is the file data belonging to a predetermined secure space and to block or hold the writing or transfer for the file data when the detected file data belongs to the predetermined secure space. | 10-30-2014 |
20160063264 | METHOD FOR SECURING A PLURALITY OF CONTENTS IN MOBILE ENVIRONMENT, AND A SECURITY FILE USING THE SAME - There is provided a method for protecting a plurality of contents in mobile terminal, the method includes; storing a header portion for storing file names and folder structure of the plurality of contents; and a body portion for storing file binary values of the plurality of contents, when the plurality of contents are stored; wherein the file binary values of the plurality of contents is partially encrypted. | 03-03-2016 |

20090262871 | Receiver and method for detecting signal in multiple antenna system - Provided are a receiver and a method for detecting a signal in a multiple antenna system. The receiver includes a filter coefficient calculator and a signal detector. After separating a first signal portion and a second signal portion, the filter coefficient calculator calculates an MMSE filter coefficient using a Matrix Inversion Lemma such that an inverse matrix of the first signal portion has a predetermined constant value regardless of a repetition signal detection process. The signal detector detects a relevant transmission signal from an interference-removed reception signal using the MMSE filter coefficient. | 10-22-2009 |
20130083885 | BIDIRECTIONAL SHIFT REGISTER - Disclosed herein is a bidirectional shift register which is capable of preventing multi-outputs from both end stages. The shift register includes a plurality of stages for outputting scan pulses forward or reversely based on a start pulse and a plurality of clock pulses with a phase difference. A last one of the stages includes a forward scan controller for making a set node active and a reset node inactive based on any one of the clock pulses and a scan pulse from an upstream stage, a reverse scan controller for making the set node active and the reset node inactive based on any one of the clock pulses and the start pulse, and an output unit for outputting any one of a corresponding scan pulse and a deactivation voltage based on a voltage at the set node, a voltage at the reset node and any one of the clock pulses. | 04-04-2013 |
