Abstract: Disclosed herein is a method for transmitting information using a monitor brightness change. The method may include generating a transmission data frame structure for transmitting digital information, encoding the bit of the digital information, and converting the encoded bit of the digital information into a wireless signal that is a brightness change signal of blue (B) color, among red, green, and blue (RGB) for configuring colors on a monitor.

Abstract: A display device including a substrate including a display area and a non-display area, pixels provided in the display area, an encapsulation layer on the pixels, a first conductive pattern on the encapsulation layer and including a first metal layer of sensing lines disposed in a non-sensing area corresponding to the non-display area, a first insulating layer on the first conductive pattern, a second conductive pattern on the first insulating layer and including a second metal layer of the sensing lines, and a second insulating layer on the second conductive pattern, in which the first metal layer includes a first end located in the non-sensing area corresponding to a first side of a sensing area and a second end located in the non-sensing area corresponding to a second side adjacent to the first side, and the first end and the second end are spaced apart from each other.

Abstract: Disclosed herein is a device equipped with flash memory, which includes memory in which at least one program is recorded and a processor for executing the program. The memory includes flash memory including a data area and a backup area, and the program divides data into two or more segments depending on whether the data can be stored in a single page and stores the same in the data area. The first segment is stored in a page along with a segment number, indicating the sequential position of the divided data, a segment offset, indicating the number of pages between the pages in which the current segment and the next segment are stored, the size of a data file name, the size of the data, and the file name. At least one additional segment may be stored in another page along with the segment number and segment offset thereof.

Abstract: Provided is a module and method for transmitting information using a wireless hidden signal, which is capable of transmitting important information data requiring extreme security using a wireless hidden signal, and allowing the important information to be detected and distinguished by only promised transmitting/receiving parties so that the possibility of the wireless hidden signal being discovered can be minimized and security can be enhanced. The module for transferring information using a wireless hidden signal includes: a hidden formatting unit configured to generate a transmission data frame structure based on data that needs to be wirelessly transmitted; a hidden encoding unit configured to encode the generated transmission data frame structure to generate and output a hidden encoded bit stream; and a hidden modulation unit configured to convert the output hidden encoded bit stream into a wireless signal in a wireless transmission format.

Abstract: Disclosed herein is a method for detecting a covert channel in wireless communication. The method includes setting a wireless communication specification, detecting a covert timing channel, and detecting a covert storage channel.
