MorphoSmart <strong>Overview</strong> Non redundancy principle 7-22 SAGEM Défense Sécurité Header of the structure is duplicated within each minutiae. Some data such as IBIA manufacturer OID, applicative data and signer identifier are global to the token. In order to avoid application information duplication, only the first object shall contain the format sequence. Biometric Data BiometricData field contains a template that represents the extracted biometric characteristics. X9.84 does not provide further indications within this format. Biometric data are the concatenation of: - one byte that indicates template format: Value Signification 0 PK_COMP v2 1 PK_MAT_NORM. Normalized PK_MAT 2 PK_COMP_NORM.
