Problems solved by technology

[0005] First, if the user only uses one or two passwords as all passwords, the security is not high. Once the password is disclosed in a certain place, other places where the password is used will be in danger of being stolen;
[0006] Second, if too many passwords are used to verify the identity, the user may forget one of the passwords. Once forgotten, the identity verification will not be passed, which will bring great inconvenience to the user.

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] figure 1 The flowchart of the method for generating a password string provided by the embodiment of the present invention is shown.

[0024] In step S101, the password input by the user is obtained.

[0025] In step S102, a fingerprint file is generated according to the password input by the user.

[0026] In the specific implementation process, it is also necessary to determine the size of the generated fingerprint file for use in subsequent algorithms. For example, define the size of the fingerprint file as 1024 bytes. Wherein, the generation process of the fingerprint file is optional,...

Abstract

The invention belongs to the field of password safety and discloses a method and a device for generating a password string. The method comprises the following steps of: acquiring a fingerprint file of a user; acquiring a prompt string, wherein the prompt string is characteristic information of a password object input by the user; generating password data according to a password input by the user and the prompt string; and generating the password string according to the password data and a password identifier and prompting the password string to the user. In the invention, the user only needs to remember one password without remembering masses of other passwords so as to bring great convenience to the user.

Description

technical field [0001] The invention belongs to the field of password security, and in particular relates to a method and device for generating a password string. Background technique [0002] In daily life, with the promotion of various security measures, passwords are widely used in various fields. [0003] In the process of practical application, since there are too many networks, bank cards, mailboxes, etc., passwords are required to verify the identity, and the next step can only be performed after the password verification is passed. If the user forgets the password or enters the wrong password, access will be denied. [0004] But in real life, the use of passwords has the following problems: [0005] First, if the user only uses one or two passwords as all passwords, the security is not high. Once the password is leaked in a certain place, other places where the password is used will be in danger of being stolen; [0006] Second, if too many passwords are used to v...
