  • Patent number: 10872135
    Abstract: The present invention relates to a technique of authenticating a user by using junk data randomly generated when a password is inputted. According to the present invention, a password is received from a user and is stored, and it is determined whether a password matches with an original password stored in a memory among junk data and a password inputted together in a user authentication step. At this time, if a password including the junk data matches, by at least a certain length or more, a password including junk data inputted in a previous authentication step, user authentication fails even if the separately extracted passwords match each other, such that security can be further enhanced.

    Abstract: A composition of redox-reagent containing metal-containing complex and thionine or its derivative as electron transfer mediator for use in an electrochemical biosensor, and a biosensor containing the same are provided. With the increase in reaction rate between redox enzyme-thionine (or its derivative)-metal-containing complex in the composition of redox-reagent containing metal-containing complex and thionine or its derivative, glucose detection efficiency markedly increases, and the composition is hardly influenced from high humidity and interfering substances. Accordingly, the composition of redox-reagent is useful in fabricating an electrochemical biosensor for detecting glucose in blood.
