Problems solved by technology

[0003] The problem with the cloud backup storage type password management method is: using cloud backup to transmit user privacy to the server, not only the inside of the cloud server is easy to leak, but also easy to be stolen by hackers
The problem with the local browser cache password management method is that the password is saved in a local temporary file without any encryption protection measures, and the security of the password cannot be guaranteed at all.
The system data is stored in the cloud server storage module, which is easy to be stolen by hackers
Moreover, the fingerprint password protection method given is relatively simple, and the security is not high.

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] A password security management method based on fingerprint authentication, comprising the following steps:

[0037] Step 1: The user submits a new password record D, where D={password, username, URL}, which may correspond to a username and password of a mailbox in practical applications.

[0038] Step 2: If the user is using it for the first time, the user provides their customized identification UI.

[0039] Step 3: The APP terminal of the application program derives UN according to the user identification UI, and transmits it to the password management device.

[0040] The method of deriving UN from the user ID UI is as follows:

[0041] UN=PBKDF2(UI,count)

[0042] In the formula, the value of count satisfies the requirement of second-level calculation on processors with poor performance, which is used to prevent hackers from enumerating UN...

Abstract

The invention relates to a password security management method and equipment based on fingerprint authentication. The equipment comprises a central processing module, a fingerprint acquisition module, a Bluetooth module and an encryption and security storage module, wherein the central processing module is independently connected with the fingerprint acquisition module, the Bluetooth module and the encryption and security storage module. A user fingerprint is used for key manufacture to protect private data, so that the fingerprint not only performs an identity authentication function but also performs a data encryption function. A method that the fingerprint is adopted to manufacture the key can better defense the violent password attack of hackers than the method that the password is adopted to derive the key. Since the user identifier is used for the key manufacture and the user and equipment jointly participate in the key manufacture, security performance is greatly improved, other people except the user can not decode protected data, and even if a manufacture is helpless unless the user provides the user identifier and the fingerprint.

Description

technical field [0001] The invention belongs to the field of Internet information security, and in particular relates to a password security management method and equipment based on fingerprint authentication. Background technique [0002] There are mainly two types of existing password management methods: a cloud backup storage type, and a local browser cache type. The cloud backup storage type means that the user makes a backup on the server side while entering the user name and password, and the user name and password are automatically input by the plug-in of the product during subsequent use. The local browser cache type means that when the user enters the password and user name, the browser prompts whether to cache the password. When the user chooses to cache, the browser saves the password in a local temporary file. Automatically filled by the browser plug-in when the user uses the password again. [0003] The problem existing in the cloud backup storage type passwor...
