Santa Barbara to fingerprint elementary school students

Yesterday's Examiner: Three Santa Barbara elementary schools to fingerprint students. The purpose: use of the cafeteria.

A plan to fingerprint elementary school students when they buy lunch has some parents worrying that Big Brother has come to the cafeteria.

The Hope Elementary School District has notified parents that beginning this month, students at Monte Vista, Vieja Valley and Hope elementary schools will press an index finger to a scanner before buying cafeteria food.

The scan will call up the student's name and student ID, teacher's name and how much the student owes, since some receive government assistance for food.

"It raises sanitary issues, privacy issues -- it is kind of Orwellian," said Tina Dabby, a parent of two at Monte Vista Elementary. "It just sounds kind of creepy."

School administrators said the idea is to speed up the cafeteria line. The same information is currently handled with old-fashioned paper and then transferred to computer so that reports can be compiled.

Invasion of privacy? Yes. Violation of the Fourth Amendment? Not necessarily, I regret to say.

What are the competing interests?  The school already gathers this information, just without a fingerprint. Parents voluntarily fingerprint their children in case of abduction. Kids in elementary school don't have a choice because of their age, and parents are not being asked for consent. Here, the school will likely use a single finger or thumb, like used at customs for visitors coming into the U.S., or the use of a finger to access a secure computer.  Can the fingerprint stored in the school computer be used to investigate a crime? What are the internal restrictions on the use of the fingerprint? If none, the fingerprint may not be able to be used to investigate a crime later, even years later after the elementary school student has come of age to commit an offense for which he or she can be arrested.

Compare an employee of an airport working in a "sterile area" who has to use a fingerprint scan to open a door. The prison system in my home state has been using retina scans at some prisons to identify employees on entering and leaving the prison. With adults, they choose their jobs and thereby consent to the process. But, both of these examples involve adult employees who may have had to submit to a fingerprinting to get their job, so these may not be the best examples.

Orwellian? Definitely. Unconstitutional?  One would hope, but not necessarily likely, depending on what internal safeguards there are or aren't.

    Eventually, there will be ways to do this that don't raise these concerns, but I don't think we're there yet.

    I imagine, for example, that someday the fingerprint scanners will store the fingerprint not as an image, but as a giant hash of the image's data - a one-way hash so that odds of two different fingerprints calculating to the same hash are something like one in fourteen hundred bajillion.  When that works, all the system has to do is store a fingerprint hash and compare it to new fingerprint hashes on the lunch line.  That way there's no fingerprint picture on file at all, so there's no way to compare it to partial prints in some crime scene in 24 years.  Depending on the fingerprint reader, it might not even work unless the finger is inserted in the same kind of reader both times, so no print could be used against you.

    But I don't think it works today.  I think today's fingerprint readers are doing really well to be able to match two fingerprints on the same reader if one of them is slightly rotated.  Declaring two images to be equivalent is still really difficult without massive computing power and time; things like fingerprint and retina scanners today are taking very small, very specialized images to rule out a lot of the possible problem cases.

    Plus, I think it's even harder to do this right for children, because while their fingerprints remain the same in proportion as they grow up, the actual fingerprint gets larger because the child's hands (and, presumably, the rest of the body) continues to grow.  It wouldn't surprise me if they had to re-enter a child's fingerprint every 3-5 months just to account for that.

    There ought to be ways to store biometric identifying data that can't be used against you, just like they can digitally store your signature today, but I don't think we're there yet.  The stakes are obviously higher if it's any kind of government agency storing the data, be it a school or the Social Security Administration, but I'm optimistic that one day it will work.

    Parents voluntarily fingerprint their children in case of abduction

    When I was in elementary school in the early eighties, the school ran a program to have all the children fingerprinted under the guise of it would help to have our prints on file if we were ever abducted (or that's how my moms remembered it being explained to her).  I say guise because when I was arrested 15 years later...my prints were in the law enforcement database.  I don't buy for a second it was about kidnappings, it was about the state getting their greasy hands on our prints.

    I see this as another guise to get prints in the law enforcement database.  Do you trust the school (a state run entity) not to share the prints?  I advise all the kids to krazy glue their fingertips...for their own good.

    As the above reader mentioned, what if there was a way to just store data about a fingerprint instead of storing a raw image?  Well, a company that I work with has been doing this since the beginning.  I develop point of sale software which is distributed to many different industries, one of which is elementary school lunch lines.  The fingerprint scanning technology we used from M2SYS Technology scans the minutiae on the finger and encrypts it into a tiny binary string which is used for authentication.  Never at anytime is a child's fingerprint stored on file.  Even if someone was able to hack in and gain access to the database, these tiny binary strings are totally useless without the use of M2SYS' software.  And even then, the only thing the software can do is perform checks to see if the binary strings are matches.  Biometrics can be used to ease everyday life without trampling on civil rights!

    Fingerprinting not only US problem (none / 0) (#4)

    While checking around the net how wide spread fingerprinting of school kids was, I found an article at www.rinf.com/columnists/news/school-fingerprinter-repents about the director of the firm that supply's the British schools with scanners now says "he would change his advice for parents so they can make an informed decision about whether they want the school to take their children's (fingerprints)". In the article it mentions that David Clouter has started an organization called Leave Them Kids Alone campaign. This problem seems to be larger than just in the US.

    Biometrics now a days with hi tech research and up gradation, is providing new sensors and scanners with higher reliability. Fingerprint scanners are making communication and identification  much easier, safer and more reliable. I am a representative of an established research based biometric firm named M2SYS Technology http://www.m2sys.com/
      based in Atlanta Georgia. We have provided our fingerprint scanners to numerous schools and agencies starting from medium to large across various countries, who are now making a very fast and reliable client record service through integrating our secured fingerprint identification system in their software. Our's is a patent-pending fingerprint software solution that can be instantly integrated with a host application, avoiding development burdens associated with a fingerprint SDK. I believe to keep up with speed of service and tracking students in an efficient way, finger print scanners are one of the best solutions.

    Biometric Technologies a real boon for our school (none / 0) (#7)

    I think advancements of Biometric technologies are a great boon to our society, if used wisely. We run a school and consulted a company called Bayometric (www.bayometric.com ) on how Biometrics could help us. They had such wonderful ideas about using Biometrics to make it easier for students to Buy Lunch at the school cafe, borrow Library Books, have access to labs etc etc... without having to carry any money or a photo id. Our students and parents really love these systems.
