No. Data separation and reliance on templates are among the most critical security features of the system. There is no need to keep any biometric data online for the NIDS to work. NIDS will utilise biometric industry standards and utilise a template of each biometric trait. A “fingerprint” template is not a picture of the fingerprint but a simplified, schematic version of it. This template can be used to validate a fingerprint but will not reconstruct the fingerprint.
