    • Provided is an off-line two-factor user authentication system. The off-line two-factor user authentication system is designed to use, as a password, a one-time-password derivation rule to be applied to certain pattern elements included in a presentation pattern at specific positions so as to create a one-time password, and further use, as a second authentication factor, information identifying a client to be used by a user. A plurality of pattern seed values each adapted to uniquely specify a presentation pattern in combination with a client ID, and a plurality of verification codes corresponding to respective ones of the pattern seed values, are stored in an off-line two-factor authentication client. A presentation pattern is created based on a selected one of the pattern seed values and a client ID, and an entered one-time password is verified based on a verification code corresponding to the selected pattern seed value.
    • 提供一种离线双因素用户认证系统。 离线双因素用户认证系统被设计为使用一次性密码导出规则来应用于在特定位置处的呈现模式中包括的某些模式元素,以便创建一次性密码 作为第二认证因素,进一步使用标识用户要使用的客户端的信息。 多个模式种子值分别适合于独立地指定与客户端ID相结合的呈现模式,以及与模式种子值相应的多个验证码,存储在离线双因素认证客户端中。 基于所选择的模式种子值和客户端ID中的一个创建呈现模式,并且基于与所选择的模式种子值对应的验证码来验证输入的一次性密码。
