Conclusion

It is clear from examining the biometric transaction that privacy can be truly guaranteed only when adequate security measures are taken. The security measures must be in place from the time when the user is ready to authenticate to the moment when the matching decision is made.

The threats to a biometric transaction are numerous and always present. Therefore, continuous vigilance is necessary to keep the authentication and local hosts patched, and ensure that only the proper people are accessing the local host and authentication server, Even with the best security methods in place, there will still be some level of uncertainty in the transaction. That feeling of uncertainty will be directly proportional to the risk of the methods used during biometric transactions. Hopefully, an increase of time, money, and effort will sufficiently reduce the number of people able to attack a biometric system.
