Abstract: The present specification relates to a method of encrypting, by a wireless device, a data packet in advertising broadcast communication for Bluetooth low energy (BLE). The method includes: acquiring a preset unique identifier (ID) and user data, the data packet including an advertising address, a header, the unique ID, a sort ID, and the user data; encrypting the unique ID and the user data; generating a message authentication code (MAC); and generating an encrypted data packet, the encrypted data packet including the encrypted unique ID, the encrypted user data, and the MAC.

Abstract: A dyschromatopsia deciding method and apparatus is provided. The apparatus includes an I/O interface configured to receive an input for a program, a memory configured to store the input for the program and a processing result of the input, and a processor configured to execute the program, wherein the processor is configured to provide first CAPTCHA information for distinguishing between a person and a machine together with second CAPTCHA information for deciding dyschromatopsia, receive first CAPTCHA input information corresponding to the first CAPTCHA information and second CAPTCHA input information corresponding to the second CAPTCHA information together with authentication information, authenticate a user based on the first CAPTCHA input information, decide dyschromatopsia of the user based on the second CAPTCHA input information, and store a decision result of the dyschromatopsia in response to a decision that the user has the dyschromatopsia.

Abstract: An active material of the present invention has fine pores formed in the interlayer of a carbon material capable of exhibiting electrochemical double layer capacitance. The fine pores are formed by forming an oxidized graphite structure combined with oxygen in the interlayer of a part or whole of the carbon material containing soft carbon and then removing a part or whole of oxygen in the interlayer. A method for producing an energy storage active material for use in an electrochemical double layer capacitor comprises pre-treating a carbon material through heat treatment and oxidizing the pre-treated carbon material using an oxidant. The method further comprises reducing the oxidized carbon material through heat treatment. The interlayer distances of an active material for respective steps, measured by a powder X-ray diffraction method, are 0.33˜0.36 nm in the pre-treatment step, 0.5˜2.1 nm in the oxidation step, and 0.34˜0.5 nm in the reduction step.
