Problems solved by technology

[0002] In the existing Internet data transmission process and data security field, there will be many places where keys are used, and the need for keys involves the generation and use of keys. The current general method is that product manufacturers produce keys during the product manufacturing process. A key, such as a dynamic key generated by software or hardware, but there is a problem in the generation of these keys, that is, it is not generated by the user of the product, which may cause the user of the product to not know the key. However, the product manufacturer has the key or has the ability to generate the key and the method, which brings hidden dangers to the product security

Embodiment Construction

[0008] Further description will be given below in conjunction with the embodiments and accompanying drawings.

[0009] As shown in Figure 1, the present invention comprises the following steps:

[0010] (1) Extract fingerprint information: collect the user's fingerprint information on-site through the fingerprint collection device, or extract the fingerprint feature part from the file containing the user's fingerprint information.

[0011] (2) Confirm the key format: confirm the structure of the key according to the encryption and decryption algorithm used by the user.

[0012] (3) Generating an unauthenticated key: Generate an unauthenticated key from the fingerprint data extracted in step 1 according to the key format confirmed in step 2.

[0013] (4) Verification key: Apply the key generated in step 3 to the user algorithm for verification to ensure its availability. .

[0014] (5) Generate key: the key verified in step 4 is the fingerprint key, which can be used later. ...

Abstract

The invention discloses a method for taking fingerprint information as an encrypted key and an implementation process thereof. The method comprises the following steps: obtaining the fingerprint information of a user, determining the data format of the key according to the used data encryption-decryption algorithm; and extracting one section of data from the fingerprint information as the key according to the data format of the key. The method for taking the fingerprint information as the key has the advantages that the encrypted key is produced from the fingerprint of a product user, and the security of the product is improved.

Description

technical field [0001] The invention relates to the fields of Internet security and data security, in particular to a method capable of using fingerprint information as an encryption key. Background technique [0002] In the existing Internet data transmission process and data security field, there will be many places where keys are used, and the need for keys involves the generation and use of keys. The current general method is that product manufacturers produce keys during the product manufacturing process. A key, such as a dynamic key generated by software or hardware, but there is a problem in the generation of these keys, that is, it is not generated by the user of the product, which may cause the user of the product to not know the key. However, the product manufacturer has a key or can generate a key and a method, which brings potential safety hazards to the product. Contents of the invention [0003] The purpose of the present invention is to overcome the potenti...
