Problems solved by technology

[0006] However, since the client is generally a user's personal computer, the security level is generally very low, and it is very easy to be hacked or infected with a Trojan virus. Therefore, if the client computer is remotely controlled by a hacker or a Trojan virus, it is easy to transmit transaction information to The smart key device performs PIN code authentication, or performs signature encryption and other operations, and then sends it to the server for verification, thereby fraudulently using the identity information of the legitimate user for transactions, and the whole process is often not known by the user. Normal transactions bring great security risks, and in serious cases may cause economic losses to users
In addition, although the intelligent key device using biometric technology such as fingerprint verification can solve the problem of user information being intercepted, the cost of the smart key device using biometric technology such as fingerprint verification is very high, resulting in excessive use costs for users. High, and to a certain extent, it limits the volume and weight of the smart key device, which brings a lot of inconvenience to the promotion and application of the smart key device

Embodiment 1

[0056] see figure 1 , the embodiment of the present invention provides an intelligent key device for improving the security of PIN code input. modules and comparison modules,

[0057] Wherein the liquid crystal display screen is used for displaying spare characters and selected logos; specifically, the selected logos can be in the form of a cursor, a selected box or a shadow box, etc., and the spare characters are printable characters, specifically numbers, uppercase and lowercase letters or optional Entered symbols;

[0058] The selection confirmation device is used to select the character to be compared among the above-mentioned spare characters bit by bit by controlling the movement of the selected mark of the liquid crystal display. number, the selection confirming device controls the movement of the selected mark on the liquid crystal display screen and selects the character to be compared among the above-mentioned 0-9 numbers, such as selecting 13567 as the character t...

Embodiment 2

[0072] see figure 2 , the embodiment of the present invention also provides a method for improving the security of PIN code input of the smart key device:

[0073] Step 301: Establish a connection between the smart key device and the host;

[0074] Step 302: The smart key device displays spare characters and selected marks on its LCD screen. Specifically, the selected mark can be in the form of a cursor, a selected box or a shadow box, and the spare characters are printable characters, specifically numbers , uppercase and lowercase letters and symbols that can be entered;

[0075] Step 303: the smart key device selects the character to be compared among the above-mentioned spare characters bit by bit by controlling the movement of the selected mark on the liquid crystal display, for example, if the spare character is a number of 0-9, the liquid crystal display 0-9 digits, the smart key device controls the movement of the selected logo on its liquid crystal display to select...

Abstract

The invention relates to a device for improving the input security of inputting the PIN code of an intelligent key device. The invention is characterized in that the device comprises a control module, and an information security module, a USB interface module, a liquid crystal display screen, a selective acknowledgement unit, a storage module and a comparison module which are respectively connected with the control module, wherein the liquid crystal display screen is used for displaying standby characters and selected markings; the selective acknowledgement unit is used for selecting a character to be compared from the standby character information through controlling the selected markings of the liquid crystal display screen; the storage module is used for prestoring a setting PIN code; the comparison module is used for comparing the character to be compared selected by the selective acknowledgement unit with the setting PIN code prestored in the storage module; and the information security module is used for performing information security operation under the confirmed access right of the character to be compared passing the authentication of the comparison module. The inventionalso discloses a method for improving the security of inputting the PIN code of the intelligent key device.

Description

technical field [0001] The invention relates to the field of information security, in particular to a device and method for improving the security of PIN code input of an intelligent key device. Background technique [0002] In recent years, with the rapid development of the network and the great convenience it provides, people increasingly rely on network means for various activities, including identification, online banking and VPN (Virtual Private Network, also known as for a virtual private network), etc. [0003] Correspondingly, network information security has attracted more and more attention. In recent years, a kind of information security product has appeared, that is, a portable and mobile hardware device, generally called a smart key device. A small hardware device with a microprocessor. The smart key device establishes a connection with the host through the data communication interface of the host. The processor in the device generally adopts a security design...
