    Abstract: A complex authentication system that uses personal variable biometric information which changes according to times and environments, and a complex authentication method using the same are disclosed. The variable biometric information-based complex authentication system includes: a mobile terminal configured to collect variable biometric information; a variable biometric information management server configured to store the variable biometric information received from the mobile terminal; and an agent server configured to, when the mobile terminal requests a login command regarding the ID, verify validity of the login command regarding the ID based on the variable biometric information. Accordingly, even if biometric information used in an authentication procedure is leaked, a damage resulting therefrom can be inhibited, and security of the authentication procedure can be enhanced by combining different types of variable biometric information or by combining variable biometric information of a plurality of users.

    Abstract: Provided herein is a variable social network service method and apparatus. The variable social network service method includes receiving, by a variable social network service apparatus, information on whether or not a user serves as a bridge from a user apparatus of the user, and determining, by the variable social network service apparatus, whether or not to expand a social network based on the user based on the information on whether or not the user serves as the bridge, wherein the variable social network service apparatus determines whether or not social networking is possible between a first network subject of the user and a second network subject of the user depending on whether or not the user serves as the bridge.

    Abstract: The present invention relates to a glass substrate composition comprising SiO2 55˜70 wt %, Al2O3 0˜1 wt %, ZrO2 0.1˜5 wt %, Na2O 0.1˜5 wt %, K2O 7˜13 wt %, MgO 7˜14 wt %, CaO 0˜4 wt %, SrO 7˜12 wt % and SO3 0.01˜0.5 wt %. The glass substrate prepared by using the above composition shows less thermal deformation at a baking process under a high temperature since the strain point of the glass is at least 570° C., does not have such disadvantages as increase of fuel cost and short life cycle of refractories resulted from less than 1460° C. of melting point, and has 80˜95×10−7/° C. of thermal expansion coefficient in the temperature range of 50˜350° C. Therefore, the glass according to the present invention is suitable as a substrate.
