Security password input system and implementation method for intelligent terminal

Abstract

The invention discloses an intelligent terminal oriented security password input system which comprises an intelligent terminal, an external password input unit and a remote server. The external password input unit is used for displaying and encrypting graphic information and directed line segment information. An implementation method includes a), enabling the external password input unit to be in communication connection with the intelligent terminal; b), configuring graphic parameters; c), selecting directed line segments; d), encrypting password configuration information; e), transmitting the password configuration information; f), acquiring the password configuration information; g), randomly generating a regular graph; h), encrypting the graphic information; i), transmitting the encrypted graphic information; j), decrypting the graphic information and the directed line segment information; k), enabling the remote server to perform judgment. The intelligent terminal oriented security password input system and the implementation method have the advantages that passwords are configured by the aid of the graph and the directed line segments jointly and accordingly are different from one another; the real passwords of users cannot be detected even if a keyboard recorder is mounted on the intelligent terminal; the intelligent terminal oriented security password input system and the implementation method have wide application space in the field of mobile application and particularly in the field of electronic commerce and electronic governments.

Description

technical field [0001] The present invention relates to an intelligent terminal-oriented security password input system and its implementation method, more specifically, to an intelligent terminal-oriented security password input system and implementation method in which the input password has high strength and is difficult for opponents to steal. Background technique [0002] With the popularization of smartphones, IPADs, tablet computers and other intelligent mobile terminal devices with Internet access functions, it has become a trend and general trend of the information society to use such devices to realize e-commerce transactions and e-government system login anytime and anywhere. However, because users often install a large number of application software on personal smart terminals, and the security of these application software cannot be guaranteed, some malicious application software will intercept the user's keystroke information, thereby capturing the user's transa...

Problems solved by technology

However, this method has problems in operability and safety

[0003] There are two aspects to the operability problem: (1) It is not convenient for users to carry with them when the keyboard design is large; (2) It is not convenient for users to input passwords when the keyboard design is small, and it is easy to cause password input errors

[0004] The security problem lies in: for the convenience of operation and memory of the user, the external device only provides a numeric keypad, allowing the user to set a password of 6-8 digits

The strength of this password is low, it is easy to be guessed by the adversary, or observed by the adversary when entering the password

And because users often use one password for multiple applications for the convenience of memory, this will cause security problems for other applications of users.
