The invention discloses a
data processing method, an electronic device and a
server. A first private key is preset in the electronic device, and a first public key corresponding to the first private key is stored in the
server. The
data processing method includes the steps that first
user information and first biological characteristic information of a user are collected, and the correlation between the first
user information and the first biological characteristic information is built; first request information encrypted through the first private key is sent to the
server; when the server decrypts the encrypted first request information through the first public key, first response information sent by the server is received so as to confirm that
verification of the electronic device is successful; a second private key and a corresponding second public key are generated; the second private key is stored, and the second public key, the first
user information and the correlation between the first user information and the first biological characteristic information are sent to the server.
