Though fprintd generates fingerprint image with root permission for protecting the file from attackers, it is not of itself sufficient. It is well known threat model that a formatted fingerprint data can be restored to original image about a decade ago. [1-4] are presented to create sophisticated and natural-looking fingerprints only from the numerical template data format as defined in ISO/IEC 19794-2. They also successfully evaluated these approaches against a number of undisclosed state-of-the-art algorithms and the NIST Fingerprint Image Software. We need improvements of those issues. [1] R.
