Fingerprint systems that are used primarily in forensics to track criminals and compare optical prints are completely different than those used in school systems and in the private sector. With these systems, the fingerprint image is instantly converted to a binary string and the optical image is destroyed. Therefore, if someone were able to hack into the system, they would see nothing more than a series of 1's and 0's. It would be futile to try and turn this data into a fingerprint. If someone wanted to steal a child's fingerprint they could get it from a soda can much easier. My school uses software and fingerprint scanners from this company and it works great. We were able to overcome the parent's privacy concerns by explaining how the technology works.
