Abstract
The invention discloses a fingerprint identification-based encrypted transmission method, a fingerprint identification-based encrypted transmission device and a fingerprint identification-based encrypted transmission system. In the scheme provided by the invention, when sending information to a specified receiving end, a sending end can first send self fingerprint information to a fingerprint authentication center, and when the fingerprint authentication center judges that the fingerprint information of the sending end belongs to a user authenticated by the receiving end, the sending end can obtain a public key generated by the receiving end in the fingerprint authentication center and use the public key to encrypt the information. When receiving the encrypted information, the receiving end can decrypt the encrypted file according to a private key generated by the receiving end, consequently, in the process of sending the information to the receiving end, the file is always encrypted by the key, so the information cannot be seen even if someone intercepts the information. Therefore, the scheme provided by the invention can guarantee the security of the information in the process of transmission.
Description
Technical field
The present invention relates to the fingerprint identification technology field, in particular, relate to encrypted transmission method, Apparatus and system based on fingerprint recognition.
Background technology
In the process of internet development, the information in the Network Transmission more and more is difficult to protection, so the fail safe of strengthening in the Network Transmission has great importance.

In case it is the finger print information of receiving terminal authentication that this user's finger print information is confirmed at the finger print identifying center, the finger print identifying center will send to transmitting terminal with the PKI corresponding to this receiving terminal so.
In addition; The PKI AES that to be receiving terminal generate according to user's finger print information and RSA Algorithm in advance, the private key corresponding with PKI can be mentioned in the back, after utilizing PKI that information is encrypted; Need use the private key corresponding with this PKI deciphers just and can check this information; Certainly, RSA Algorithm is a preferred version, also can adopt other algorithms to cooperate finger print information to generate PKI and private key.Each user at the beginning of account is created at the finger print identifying center; All need fingerprint storage with this user in the database at finger print identifying center; Receiving terminal generates a PKI and private key according to this finger print information; Promptly each other corresponding PKI and private key, and PKI sent in the database at finger print identifying center, private key is kept at receiving terminal; And this user need select to use other users of this PKI, and other users' of the PKI that can use this user finger print information will be preserved in the finger print identifying center.
Step S14, utilize said PKI that the information of said receiving terminal of giving to be sent is encrypted;
Wherein, before information is sent to receiving terminal, need to utilize PKI to encrypt information to be sent.
Step S15, the information after will encrypting send to the said receiving terminal with private key, and said private key is finger print information that in advance generate and the decipherment algorithm of with said PKI corresponding of receiving terminal according to said user.
Wherein, during the information of receiving terminal after receiving encryption, can utilize private key to come this information is deciphered, if this private key and the corresponding words of this PKI can be deciphered the information after encrypting so smoothly; If this PKI is not corresponding with this PKI, can't decipher the information after encrypting so.
See also shown in Figure 3, the flow chart of shown in Figure 3 is another kind of encrypted transmission method based on fingerprint recognition, shown in Figure 3 is the method flow at finger print identifying center, this encrypted transmission method specifically comprises:
Step S21, obtain the PKI that receiving terminal sends;
Wherein, preceding text are mentioned, and receive to generate the private key that is used for the PKI of information encryption and is used for decrypts information, and receiving terminal can send to the finger print identifying center with PKI, and private key is stayed in this locality.
Step S22, obtain the finger print information that transmitting terminal sends;
Wherein, this finger print information is the user's of transmitting terminal.
Step S23, judge whether finger print information is the finger print information of receiving terminal authentication;
Wherein, Whether the finger print information that need check the receiving terminal authentication in the database comprises transmitting terminal user's finger print information, if comprise, can send to transmitting terminal by the PKI that this receiving terminal is corresponding so; If do not comprise, so just return to the prompting of transmitting terminal finger print information mistake.
Step S24, when said finger print information is the finger print information of receiving terminal authentication, then send PKI to said transmitting terminal, said PKI to be receiving terminal generate according to said user's finger print information in advance and with the corresponding AES of the private key of said receiving terminal.
See also shown in Figure 4ly, shown in Figure 4 is another flow chart based on the encrypted transmission method of fingerprint recognition, and shown in Figure 4 is the method flow of receiving terminal, and this encrypted transmission method specifically comprises:
The private key that step S31, generation are used for the PKI of information encryption and are used for decrypts information;
Wherein, receiving terminal can generate the PKI and the private key of mutual correspondence, and this PKI is sent to the finger print identifying center.
Step S32, obtain that transmitting terminal sends utilize the information behind the public key encryption;
Wherein, this information is by the state of public key encryption, deciphers corresponding to the private key of this PKI if receiving terminal is wanted to check to need to utilize.
Information after step S33, the utilization private key corresponding with said PKI will be encrypted is deciphered, and said private key and PKI are the corresponding algorithm that receiving terminal generates according to user's finger print information in advance.
Wherein, receiving terminal utilizes private key that the information after encrypting is deciphered, if this private key does not correspond to this PKI, can't decipher this information so, if this private key corresponding to this PKI, then can be deciphered this information.
At Fig. 1 to the embodiment shown in Figure 4; In scheme provided by the invention; When transmitting terminal sent to the receiving terminal of appointment to information, transmitting terminal can be earlier sends to the finger print identifying center with oneself finger print information, when the finger print information of judging this transmitting terminal when the finger print identifying center is the user of receiving terminal authentication; This transmitting terminal can get access to the PKI that is generated by receiving terminal in the finger print identifying in the heart, and information is encrypted through said PKI.When receiving terminal is received this information encrypted; Can decipher the file of this encryption through the private key that generates according to said receiving terminal; So send in the process of receiving terminal in information; File is in by under the state of key encryption all the time, even this information of people's intercepting is midway arranged, so also can't check this information.Therefore, scheme provided by the invention can the fail safe of guarantee information in transmission course.
Need to prove that Fig. 1 is the preferred embodiment that the present invention introduces to embodiment shown in Figure 4, those skilled in the art can design more embodiment on this basis fully, therefore do not give unnecessary details herein.
Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
