Screen input keyboard generation method and apparatus

Abstract

Embodiments of the invention disclose a screen input keyboard generation method and apparatus. The method comprises the steps of obtaining a first character set contained in a predetermined password and determining first quantity of different first characters in the first character set; then, determining the quantity of inputable characters on an input keyboard, wherein the inputable character quantity is greater than the first quantity; and obtaining a second character set, wherein the second character set contains second quantity of different characters, the sum of the first quantity and the second quantity is equal to the inputable character quantity, and characters contained in the second character set are other partial characters except the first characters, namely, the inputable characters on the input keyboard are not all characters and only include partial characters. Therefore, the key quantity required by the input keyboard can be reduced and the size of a single key can be increased; and the probability of falsely touching the key by a user is reduced and the password input accuracy is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a method and device for generating a screen input keyboard. Background technique [0002] Smart terminals (for example, smart phones, tablet computers, etc.) have become one of the essential and important tools in people's daily life. With the rapid development of the mobile Internet, users store more and more personal information or private data in smart terminals (such as mobile banking, Alipay, etc.). Pay attention to. [0003] Many built-in functions of smart terminals (for example, address book, SMS, etc.) do not have independent unlocking passwords. Therefore, unlocking the screen is an important guarantee for protecting these private information. Character passwords such as numbers and letters are one of the commonly used passwords in screen unlocking passwords. If the unlock password is a purely numeric password, the on-screen soft keyboard is a numeric keyb...

AI Technical Summary

Problems solved by technology

[0004] Numerical passwords are too simple, which increases the risk of unlocking passwords being stolen; alphabetic passwords are relatively safe, but users need to enter the password on the full keyboard when entering the unlocking password. The full keyboard contains a large number of keys, and the screen size is limited. The size of each button is very small, and the user can easily touch other buttons when entering the password, which reduces the accuracy of password input
