A biometric certifying authority (BCA) management system and method provide and maintain a hierarchical relationship among biometric certifying authorities in the issuance of biometric certificates. Biometric certificates may be used in all electronic transactions requiring authentication of the participants, based on the accuracy and uniqueness of the biometric, which allows the electronic transaction to be insured to provide global standards for all electronic commerce. The BCA management system includes a transaction request parser which extracts a biometric certificate signal and transaction-type data from a electronic transaction request. A biometric verification processor verifies the biometric certificate signal against previously stored biometric data in a database. The biometric verification processor generates a verification message corresponding to the authenticity or fraudulent status of the biometric certificate signal. A transaction type classifier receives the electronic transaction request, and generates a classification message according to the transaction-type data. A certifying authority processor generates an access-or-denial message to indicate the status of the electronic transaction, and to report the classification of the transaction request.
