Abstract
A personal information security system and a method thereof ensuring irreversibility and similarity are proposed. According to specific exemplary embodiments of the present technology, the personal information security system includes a feature vector extraction unit for extracting a feature vector from user modality information, an Absolute Value Equations Transform (AVET) unit for performing absolute value equations transform on the feature vector, and a transformed-template generation unit for generating a transformed template (TT) from which the feature vector is unable to be predicted reversely from a result of the AVET.
