Communication method utilizing fingerprint information authentication

A communication method utilizing fingerprint information authentication, comprising the steps of:

• (a) extracting fingerprint information of a first user by means of a collection and recognition device of a fingerprint sensor and transmitting the fingerprint information to a information exchange platform, sending a request instruction to a second user through the fingerprint information on the information exchange platform by the first user, and confirming the request after receiving the request instruction by the second user and extracting fingerprint information of the second user by means of the collection and recognition device of the fingerprint sensor, and storing the fingerprint information of the second user in the information exchange platform and exchanging the fingerprint information of the second user with the first user to verify their identity;
• (b) extracting fingerprint information of the first user and authenticating the identity of the first user by the collection and recognition device of the fingerprint sensor, inputting a message to be sent in an encrypting unit by the first user after passing the authentication, to obtain an encrypted message, and then transmitting the encrypted message to a communication application unit and sending it to the second user, and receiving the encrypted message via the communication application unit by the second user;
• (c) extracting fingerprint information of the second user and authenticating the identity of the second user by the collection and recognition device of the fingerprint sensor, and decrypting the encrypted message by means of a decrypting unit and reading the decrypted message by the second user after passing the authentication.
