no. 1 example

[0026] According to the first embodiment of the present invention, refer to figure 2 , the encryption machine downloads the key to the fingerprint module.

[0027] The key download host 61 connects the fingerprint module 10 and the encryption machine 60 for data transmission and initiation of download requests.

[0028] 1: The key download host 61 initiates a download external authentication request to the fingerprint module 10, the encryption unit 17 of the fingerprint module 10 generates a random number A, and the fingerprint module 10 initiates a download external authentication request to the confidential computer 60, and the request information includes the random number A.

[0029]2: Encryptor 60 encrypts random number A with the download external authentication key; and sends encrypted data A to fingerprint module 10 for download external authentication.

[0030] 3: The fingerprint module 10 verifies whether the encrypted data A is correct and valid through the encryp...

Abstract

The invention provides a fingerprint module with an encryption unit, which is characterized in that the fingerprint module is connected with a payment terminal or arranged on the payment terminal by a communication line; the fingerprint module is provided with a fingerprint acquisition unit which is at least used for acquiring fingerprint image data of a user; the fingerprint module is provided with a fingerprint processing unit which is at least used for extracting fingerprint characteristic data from the fingerprint image data of the user; and the fingerprint module is provided with the encryption unit which is at least used for encrypting the fingerprint characteristic data of the user and / or adding an MAC (message authentication code) to the fingerprint characteristic data. The fingerprint characteristic data of the user are sent out after secret keys and dynamic random numbers are used to encrypt the fingerprint characteristic data of the user and / or add the MAC to the fingerprint characteristic data of the user in the fingerprint module; and a fingerprint data validation party validates the validity of the MAC firstly and / or carries out fingerprint matching on the decrypted MAC, thus avoiding the possibility that a lawbreaker counterfeits a transaction request after recording fingerprint data of the user, improving the system safety, ensuring the privacy of the fingerprint data of the user and the capital safety, and being beneficial to promoting applications of a fingerprint identification technology in the payment field.

Description

technical field [0001] The invention relates to the field of fingerprint identification and the field of financial payment. Background technique [0002] The current fingerprint recognition is widely used in the fields of access control and payment. In the access control system, the access control controller saves the user's fingerprint data, and the collected user fingerprint data matches the user fingerprint data saved by the access control controller, which can meet the needs of the access control system. In the field of financial payment, the fingerprint collection module directly sends the user's fingerprint data, and there is a problem of user fingerprint data leakage. Criminals can record the user's fingerprint data and forge transaction requests. Contents of the invention [0003] In the present invention, the user's fingerprint feature data is encrypted using a key and a dynamic random number inside the fingerprint module and / or the message authentication code is...
