The present invention provides authentication equipment having functions for prevention of erroneous authentication using biometrics data, and which can reduce the burden of registration placed on users. The authentication equipment is characterized in comprising an input portion, which generates primitive-format information of biological characteristics based on biological characteristics specific to individuals; a primary information extraction portion, which extracts primary information identifying the biological characteristics from the primitive-format information; a secondary information extraction portion, which extracts, as secondary information, a part of the primitive-format information using the primary information; a registration portion, which stores in a storage portion the secondary information extracted by the secondary information extraction portion; and a verification portion, which compares the secondary information extracted by the secondary information extraction portion with secondary information stored in the storage portion, and judges whether authentication has been successful.
