FAA and flight routes

Recently, over the objections of many privacy advocates and airplane owners, the FAA moved to make more flight route information open and publicly available. Specifically, the FAA operates a program called BARR (Blocked Aircraft Registration Request), which allows certain aircraft to be exempt from the public records of flight routes. The FAA collects these flight routes for every flight in and out of the US in order to deal with traffic control issues, congestion, etc. However, this could be clearly sensitive information for some aircraft, those with at risk passengers or cargo, those doing surprise inspections on facilities, etc.

This is very typical of government modus operandi: collect potentially sensitive information and then attempt to secure it (or it’s analogy, making it illegal to look at information that clear for all to see). Although in this case the government has made it much more stringent criteria to be excluded, baring those who may have a legitimate interest in securing their flights that don’t meet the government threshold. This very much reminds me of the law surrounding employee addresses (or other PII) for government employees in Florida. Florida has very broad public records laws and generally, one can get the home addresses of government employees. There are numerous exceptions, for judges, law enforcement, child protective service employees, etc; those deemed by the state legislature as being high risk. This solution is no solution though, because one it deprives the citizenry of public records and adds to the long list of exemptions to the public records and second it deprives individuals of control of their personal information. A better solution would be not to collect home address information from employees, or at least give them the option of not supplying that information in the first place.

Returning to the FAA issue, there are other options. Assuming they do need it for legitimate purposes, the FAA could collect the information in such a way that it doesn’t have the information directly but only in the aggregate (to assess congestion, etc). If it needs the information for legitimate law enforcement purposes, it could use some key escrow or blinding method to store the information but only have it available with a valid court order. Without knowing all the functional requirements of the system, it’s hard to design a privacy protective method, but my purpose is to say that it could be done…… if someone cared enough to do it.
