The predictiоns оf а wоrld without pаsswords аre yet to come true but we are seeing increased use of biometric authentication methods. For example, voice-biometric is used by voice assistants that are becoming increasingly popular. Since microphones are pervasive now, consider the following password hardening authentication proposal based on voice. At the time of making a login request, a user must clearly say each character in the password. A fingerprint is derived from the uttered character sound and compared with a stored fingerprint for the character, and a similarity threshold t is set (higher value of t means the sounds are more similar). If the similarity between the fingerprints of a character is clearly above (below) t, it is a match (mismatch). Otherwise, the similarity is undefined. To successfully login, a user must utter the correct password characters and there should be similarity match in at least n of the m password characters. The false accept rate (FAR) in this scheme can be decreased by which of the following actions. I. increasing n.II. increasing t.III. decreasing n.IV. decreasing t.
