Generation of key sequences based on voice messages

The problem of the generation of the key sequences on the basis of biometric data is described. Objective: To develop a method of generating a key sequence based on the subject of voice parameters with indicators of reliability and key length exceeding achieved. Two features spaces of human voice are proposed: dependent and independent of the uttered phrase. The methods of generating keys based on voice messages on the basis of fuzzy extractors using Hadamard or Bose — Chaudhuri — Hocquenghem error correcting codes are proposed. Also the ranking procedure of most stable features individual for each subject was proposed. The effectiveness of the proposed method was defined. The optimum methods for each proposed feature space have been found. These results are superior to previously achieved by generating a key sequence based on voice. Read more...
