Problems solved by technology

But the disadvantages are obvious. Using the pressure sensor increases the user's cost of use. At the same time, the pressure sensor only generates three pressure signals, and the password is relatively easy to crack in a certain program.

Embodiment 1

[0055] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0056] A password input method, comprising the following steps:

[0057] S1: Obtain more than 2 characters to obtain the first password; record and save the time point at which the characters are obtained;

[0058] S2: Calculate the time interval value of adjacent characters of the first password according to the time point to obtain a time interval value set;

[0059] S3: Obtain a second password according to the first password and the time interval value set;

Embodiment 2

[0061] A password input method, comprising the following steps:

[0062] S1: Obtain more than 2 characters to obtain the first password; record and save the time point at which the characters are obtained;

[0063] S2: Calculate the time interval value of adjacent characters of the first password according to the time point;

[0064] S21: Obtain one time interval value in sequence to obtain a first time interval value;

[0065] S22: If the first time interval value is less than the arithmetic mean value of all the time interval values, set the second time interval value to 0;

[0066] S23: If the first time interval value is not less than the arithmetic mean value of all the time interval values, set the second time interval value to 1;

[0067] S24: Repeat S21, S22, and S23 to obtain the second time interval value corresponding to the first time interval value;

[0068] S25: Take the second time interval value of four consecutive digits to form a four-digit binary number, ...

Embodiment 3

[0073] A password input method, comprising the following steps:

[0074] The user enters the password abc123, and the time interval values ​​of adjacent characters in the input password are 2s, 3s, 3s, 1s, 3s respectively;

[0075] The time interval value is compared with the average value of all time interval values ​​2.4s, if the time interval value is less than the arithmetic mean value of all the time interval values, the time interval value is set to 0; if the If the time interval value is not less than the arithmetic mean value of all the time interval values, the time interval value is set to 1; thus, 0, 1, 1, 0, 1 can be obtained, which can be combined into a five-digit binary number 01101 ;

[0076] The method of converting the five-digit binary number 01101 into a hexadecimal number is as follows: from left to right, each binary number and the following three binary numbers form a new four-digit binary number, because the last three cannot Form a four-digit binary ...

Abstract

The invention provides a password input method and device. The password input method comprises the following steps: acquiring two or more characters and obtaining a first password; recording and storing a time point of acquiring the characters; calculating time intervals between adjacent characters of the first password according to the time point, and obtaining a time interval set; and according to the first password and the time interval set, obtaining a second password. The method improves the password strength, so that passwords are not easy to crack, and thus the password input method is secured and reliable.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a password input method and device. Background technique [0002] In the prior art, passwords are all composed of numbers, letters and special symbols. Based on convenience considerations, generally too long passwords will not be set. The shorter the password length, the lower the security; It is easy to be peeped and remember the password, which further reduces the security of the password. [0003] The Chinese invention patent with the application number of 201510767006.6 discloses an enhanced transaction password input method and device, which includes the following steps: according to the user's pressing force on the screen when inputting the transaction password, a corresponding pressure signal is generated; the pressure signal is converted into characters ; Superimpose the characters on the input transaction password; repeat the above steps to input the enhanced transact...
