1. improve a method for information input safety, it is characterized in that, comprising:

  • Intelligent key apparatus is connected by USB interface or eSATA interface or SDIO interface or pcmcia interface and terminal;

    When described intelligent key apparatus receives the authentication instruction that terminal issues, play media information corresponding to character data in order;

    User is by the direct input select signal of intelligent key apparatus;

    The character data that the media information play when described intelligent key apparatus stores input select signal is corresponding, as the authentication information of user'"'"'s input;

    Described intelligent key apparatus performs certification, and the authentication information described user inputted is compared with the authentication information of the validated user be stored in check code district, if the result of certification is by certification, then terminates identifying procedure;

    If the result of certification is not for pass through certification, then judge whether the number of times of user'"'"'s input authentication information when carrying out authentication at every turn arrives predetermined value, if the result judged is as exceeding predetermined value, then terminate identifying procedure and lock intelligent key apparatus, described intelligent key apparatus can not reuse;

    If the result judged is not as exceeding predetermined value, continue to perform identifying procedure;

    If within the input cycle of playing same media information, be directly inputted into few one by described intelligent key apparatus and select signal, then described intelligent key apparatus stores at least one character data corresponding to play media information, and the number of this character data is identical with the number of inputted selection signal;

    The mode of described user'"'"'s input select signal can be by button input, also can for by input modes such as acoustic control, body temperature induction, pressure, photoinduction.
