The opt-in nature of this process gives people much more control over the use of their biometric data.

When asked to provide your fingerprints for identification purposes, how often do we consider how the matching is performed? Whilst standards exist for the robustness of fingerprint matching when used within the Criminal Justice System, can we assume that the same standards apply to border control systems? Generally, the fewer comparison points to be analyzed, the faster the matching system; in a border control situation where a large quantity of people are being processed, it is important to understand how much of a trade-off between speed and accuracy has occurred.

If an attacker was to gain access to the encoded fingerprint data used to unlock your phone, they would likely not be able to use the data for other applications, as different systems will make use of different encodings and fingerprint details.

Should you gain access to a complete fingerprint, you can use the data to compromise any other authentication system which relies upon fingerprint data to act as a password or sole authentication factor.

We are asking people travelling through borders to place a lot of trust in the security of the collected data.

The people going through these places are forced to place a lot of trust in the collecting country to handle their data accurately and securely.
