Abstract
A multi-factor biometric authenticating device and method generates error correction based partial encryption key seed data based on a plurality of sample biometric inputs, such as raw biometric data The error correction based partial encryption key seed data serves as a partial seed for generating a secret encryption key for encrypting user data. The first partial seed is combined with a second partial encryption seed to generate the secret encryption key. The device stores the error correction based partial encryption key seed data and does not store the secret encryption key.
