Abstract

Biometric data such as iris, facial, or fingerprint data may be obtained from a user. A public code may be generated from the biometric data, but does not obtain any of the biometric data or information that can be used to identify the user. The public code includes information that can be used to extract from the biometric data a biometric code that is suitable for bitwise comparison. Neither the underlying biometric data nor information from which the biometric data may be determined is stored as only the public code and the actual biometric feature of the user is required to generate the biometric code.

Abstract

A biometric capture is performed to capture multiple regions of a biometric modality of interest, such as regions of a user's face. A complex representation of the user's biometric data is generated, such that each data point within the complex representation is based on biometric information from multiple of the captured regions. Information that later allows reconstruction of the complex representation from another capture of the user's biometric information is stored in a public code that does not include any of the underlying biometric data from the user or information that can be used to derive the underlying biometric data.

Abstract

An optical system is able to capture images of at least a portion of a candidate's face within a near field, a medium field, and a far field. For images captured within the near field, data representing the candidate's iris may be captured from the image and compared to know iris data. For images captured within the medium field, data representing the candidate's iris and facial featured may be captured from the image and compared to know iris data and facial data. For images captured within the far field, data representing the candidate's facial features may be captured from the image and compared to know facial data.
