Abstract

The embodiment of the invention provides an input character protection method and system and an electronic device. The method comprises the first step of detecting whether information input by a user conforms to a first rule, the second step of displaying characters corresponding to the information input by the user in a first display mode when the information input by the user conforms to the first rule, and the third step of displaying the characters corresponding to the information input by the user in a second display mode when the information input by the user does not conform to the first rule. According to settings of the first rule, as long as the information input by the user conforms to the first rule, the characters corresponding to the information input by the user can be displayed in the first display mode all the time, the problem that when an input focus switches from a password input box to other input boxes, a large leakage risk of a user password exists is solved, and consequently the safety of the characters input by the user is improved.

Description

technical field [0001] The present invention relates to the technical field of passwords, and more specifically, to an input character protection method, system and electronic equipment. Background technique [0002] With the development of information technology, people pay more and more attention to information security, especially the password security. At present, there are many ways to protect passwords, such as using secret security cards, electronic passwords, etc., all of which are password-protected through password verification; and as a password display technology for terminal interfaces, asterisk passwords have been greatly popularized , the asterisk password can be used to hide the password entered by the user in the password input box, so as to achieve the purpose of password protection. For example, when users use electronic devices such as laptops, smart phones, and handheld computers to log in to accounts or confirm transactions in online banking systems, i...
