1. A fingerprint authentication method, wherein the fingerprint authentication method comprises:
acquiring target fingerprint data of a user using at least one fingerprint sensor;
determining a preliminary authentication result of the target fingerprint data based on at least one historical fingerprint data stored in memory, the determining including analyzing a real-time minutia included in the target fingerprint data and a historical minutia included in the at least one historical fingerprint data;
performing a matching check on the preliminary authentication result, the matching check including analyzing at least one surrounding feature associated with the real-time minutia and at least one surrounding feature associated with the historical minutia; and
determining a final authentication result of the target fingerprint data based on results of the matching check.
