Abstract: A communication system retrieves profile data corresponding to a user profile of a second user, identifies a status message in the profile data, display, via a user interface of the instant messenger application, the status message; in response to receiving, via the user interface, a user input associated with the status message: query, based on the status message, a database to identify one or more items, and display, via the user interface of the instant messenger application, item data corresponding to the one or more items, receive, via the user interface, a user input associated with the one or more items, instantiate a transaction authentication of the one or more items by causing transmission of transaction information data associated with the first user, and cause, based on the transaction authentication of the one or more items, delivery of the one or more items to an account of the second user.

Abstract: Provided is a method of operating a terminal. The method includes determining a profile item applicable to the profile view for the account based on an input received by the terminal and a coordinate indicating a position where the profile item is provided on the profile view. The method includes displaying the profile item on a screen of the terminal based on the determined profile item and the determined coordinate. The method includes receiving an input related to the profile item, and displaying a visual effect corresponding to the input on the screen.

Abstract: Disclosed is a system for monitoring data flow for security including: a computing device for executing an application program and creating human-readable print-out data; and a control unit for receiving information, which is associated with the human-readable print-out data from an application program, and controlling a printing device based on the received information, wherein the information has an attribute of the human-readable print-out data to be output. The attribute of the human-readable print-out data is provided by a security program which is installed in the computing device, the attribute includes at least user's IP of the computing device, and the information is merged into the human-readable print-out data by the printing device.

Abstract: Disclosed is a total system for preventing an online and off-line leakage of information, which includes a security maintenance client having a program storing a file in a storing device and a file security control part which encodes the file content to be stored in the storing device and stores a log information, and security maintenance server which receives the log information and a decoding key and decodes the encoded file. The security maintenance client further includes a communication security control part which has a communication program transmitting a file and encodes the file content to be transmitted to a transmission destination of a network and stores a log information. The security maintenance server further includes an automatic key transmission part which receives a decoding key to be transmitted to the transmission destination according to a file transmission security policy after receiving the log information and the transmission destination.

Abstract: An information security system for tracing information outflow from a remotely accessible computer or computer network is disclosed. The system includes an internal communication system that has at least one internal computer for transmitting security information by tracing data through communication equipment, outputting the data to an external output means, and connecting the internal computer to an external network. A communication monitoring device stores information regarding the data that is to be transmitted by applying a security policy according to a security grade assigned to the destination to which the data is to be transmitted. The communication monitoring device is configured for extracting the identification of the destination from the transmitted data.

Abstract: A magnetic recording/reproducing apparatus without a need to adjust what is known as X-distance of an Audio/Control head. In one embodiment, the apparatus comprises a reference pulse generator, a delay control pulses generator, and a first and second delay circuits. The apparatus compares the phase of a reproduced control pulse with that of a generated reference pulse and phase-shifts the reproduced control pulse in order to synchronize both pulses. By synchronizing the pulses, the apparatus compensates for the deviation of the X-distance. Another embodiment may be implemented using a microprocessor.
