Claim 10:
11. An authentication device, comprising:
a processor and a memory having computer instructions stored therein, the processor, when executing the instructions, is configured to:
receive a command of an upper host;
parse an option parameter in the command of the upper host;
determine a value of a fingerprint authentication identifier in the option parameter; and further configured to determine whether a user operation verification result is success or failure;
based on the determining the value of the fingerprint authentication identifier in the option parameter is a first preset value, prompt the user to input a fingerprint and verify the fingerprint input by the user to obtain the user operation verification result; and further configured to, based on the determining the value of the fingerprint authentication identifier in the option parameter is a second preset value, prompt the user to press a key and verify the key pressed by the user to obtain the user operation verification result;
based on the determining the user operation verification result is failure, report an error;
set an authentication mode confirmation identifier according to the value of the fingerprint authentication identifier;
obtain client data from the command of the upper host;
generate data to be signed according to the authentication mode confirmation identifier and the client data, perform a signature operation on the data to be signed and generate a signature result; and
send the signature result generated by the second generating module to the upper host.
