Abstract:
1. A dynamic interactive identity authentication method in which a user password comprising a number of characters chosen from a parent character set in advance is authenticated, characterized in that the method comprising: locking a lock body; generating, based on said user password, an L-digit binary sequence at random, said binary sequence comprising M valid digits and L-M interference digits; generating, based on said binary sequence, L display character sets each containing at least two characters upon an identity authentication request, said L display character sets comprising M valid character sets and L-M interference character sets, each of the said valid character sets containing one valid password character, each of the said interference character sets containing none of the valid password character; wherein both L and M are integers greater than 0, L>M; forming a L-digits dynamic inputting code by choosing each one of the characters from each one of said display character sets generated and inputting the chosen characters, said dynamic inputting code comprising valid inputting character(s) chosen from said valid character set(s) and interference inputting character(s) chosen from said interference character set(s); comparing said dynamic inputting code with the user password; and unlocking said lock body when the result of said comparison is identical.
