Child-Suitable Alternatives To Passwords?

An anonymous reader writes "Two months ago I donated my old PC to my little sister, who is 7 — I had promised she would get her own computer as soon as she can read and write properly. I then proceeded to answer her questions about how it works, as far as she inquired, and tried to let her make some choices when installing Debian (she can already use GNOME). As I explained password protection and encryption to her, I was pleasantly surprised when she insisted on protection measures being as strong as possible, so that no one else can screw with her computer. She knows that my younger brother has to endure strict parental control software that was installed on his machine without his consent. The significant problem is that she cannot permanently memorize abstract passwords, even if they are her own creation. I talked with a teacher who assured me that this is common at her age. My parents would probably be able to guess non-abstract passwords. What mechanism of identifying herself does the Slashdot crowd suggest?"

    Would a fingerprint reader be suitable?

    1. Re:Fingerprint Reader? by KillerBob · · Score: 5, Informative

      A fingerprint reader wouldn't work. Fingerprint reader software (such as the wonderfully open source ThinkFinger) map out a fingerprint by locating easily identifiable marks, such as swirls or dead-ends, and map their proximity to other easily identifiable marks. As this girl is seven its fair to assume that in a few more years her fingers will be twice their current size.

      The fingerprint will be the same, but scaled up so all proximity will be lost.


      The fingerprint readers we use in our computers at work read by proportional distance, not physical distance. If you define the distance between two key points at opposite ends of the finger as a distance of 100% and an angle of 0 degrees, the rest of the points are defined using those terms. So Point C may be at 23 degrees left, 15% distance, point D may be 16 degrees right, 4% distance, etc.

      In that case, the fact that the finger grows larger over time makes no distance, because the points it's measuring are still in the same position, proportionally, just with a different scalar multiplier.

  3. Why keep her parents off exactly ? by garett_spencley · · Score: 5, Insightful

    Seriously, she's 7?!

    I have two daughters around the same age. They share a computer that we gave them for xmas. They have their own accounts, with their own passwords and my wife and I maintain the Administrator account. I could not fathom them having an Internet-accessible computer without us having full control over it.

    Am I missing the point ? Because when I read:

    "My parents would probably be able to guess non-abstract passwords"

    it sounds to me like you're trying to keep a 7 year-old's parents off of a computer she uses when they have every right (and reason / responsibility in this day in age) to know what their young child is doing on a computer.

    Of course I am all for teaching kids how to be security conscious and protect their private data. But it's a fine balance. Parents need to keep themselves in the loop in order to, you know, be effective parents.

    Thank you to all who have pointed out that perhaps locking the parents out is not a sensible goal. While I think it is good for a child this age to understand the concepts of security and privacy, I don't think that it is reasonable for a minor to expect her own little private computing world, free of parental control. There should be some semblance of openness and trust in a healthy household, particularly between parents and their children.

    As a parent, there's no way in a hell a 7 year old will have a lock down to keep mom and dad out, no responsible parent will allow such a thing, and the machine gets taken away if such a practice is put into place.

    When your 18, go right ahead and make the 53 ch4R@ct3R password to lock your machine up, until then, accept the fact that you are the child and we are the parent, and you don't get root access or personal and private encryption, you ask the IT department (dad).

    I was shocked a number of years ago when I was moving some furniture so the floors could get cleaned behind the beds. There, under my (then) five year old's mattress, was a complete list of all of my (and my wife's) passwords. He had everything (from multiple machines): power-on passwords, logon passwords, email account passwords, merchant passwords--even our online banking passwords!

    [No, they were not all the same. Some of them were quite complex, too, like 'ni*45FPN!ng'. I got to play "change-the-password" for a few hours that evening.]

    I asked him how he got them: he shoulder-surfed us for every one of them. The reason he had them? He wanted to sneak down to the computer at 3 in the morning and play Spooky Castle.

    That scared the snot out of me. Now, I know he may not be the typical kid, but it just goes to show that you really can't be too careful with your passwords.

    As to the boy, I started encouraging him to use his powers for good. I teach network administration at an area college, so I started bringing him with when I had to configure the lab. He caught on quick, and was a huge help. He's just over 11 now, and while he's still one of the most tech savvy kids in the house, he has little interest in PCs (that might be a good thing). He'd rather spend time outdoors (even when it's thirty below zero) or with his pet cockatiel.

      If you're open about it, then the idea that there is automatic resentment is just bullshit. Seven-year-olds shouldn't get unresticted and expecially not unmonitored access to the internet. Should the kid be able to keep a private journal, sure. Electronically? Maybe, I don't know about that. Should the parents know who the kid is e-mailing, hell yes. Should the parent read e-mails to the friends, once they have been identified? Well, that's where you get into trust issues. When the kid is seven, yes. When the kid is sixteen, probably not.

      Easy solution: the computer doesn't get 'net access. There's no reason an unplugged box shouldn't be as private as the child wants it to be; computers are no more dangerous than a pen and paper. Problems only occur when children don't take proper precautions online. There's no reason, in 2008, that a child should not have unfettered access to his/her own system, including root.

      When I was 5, my family moved to a new house in which I for the first time had a lock on my bedroom door. I didn't really care about it, but my father for some reason was very uptight about it and made a big deal about telling me that I was never, ever to lock my door.

      When I was 7 or 8, I went into my room one day and closed the door, and didn't notice that the lock accidentally jiggled itself to locked. (The knobs were cheap junk and the locks were overly loose, so this happened occasionally.) My father tried to come into my room moments later, and flew into a rage when he found the door locked. He refused to believe me that I had not intentionally locked the door, and as punishment he removed the door from my bedroom - for two years.

      I never forgave him for that. It was very traumatic for me. I couldn't bring myself to even speak to him for months afterward, and when he asked me to do any household chores my only reply was "when do I get my door back?". I felt nothing toward him but angry resentment for the next 10 or 12 years.

      You are not in a position to judge another family's personal interactions with regard to privacy. You don't know the people involved or their histories or their opinions. If the kid, at age 7, is already sufficiently bothered by whatever her parents did to her young brother's computer, and her elder brother is sufficiently bothered by it to try to prevent his parents from doing it to hers, maybe they're actually unreasonable nutjobs. It's not our place to judge.

      I spoke with a young woman once whose parents placed such draconian restrictions on her computer use in her teen years (severe time restrictions, IM buddy list restrictions, email restrictions, web filtering, and the software sends frequent reports to the parents with screenshots) that it actually interfered with her school work (the computer would lock her out before she could finish typing her homework), not to mention her social life (her friends had difficulty communicating with her, since her phone usage was highly restricted and parental monitored too). When they attempted to send her off to college with a laptop with their draconian control software still installed and just as restrictive as ever, she told them where to shove it and left. I'd be surprised if she ever speaks to them again.

      If the parents in the situation this Slashdot discussion is about feel that their 7 year old shouldn't be using the computer the brother gave her, they can ask him to take it back, they can put it in storage, they can ask their daughter to show them her emails and buddy lists and web favorites now and then, or they can put it in a family room so they can see what their daughter is doing with it. If they don't do these things, that's their parenting choice.

      Meanwhile, we could be having an interesting discussion of how to create decent passwords for people (like children) who are unable to remember arbitrary strings. I've met adults with the same problem, so it's not a moot question.

    A family is most definately *not* a dictatorship. It's a family, which has its own dynamic. Respecting the rights of the child (one of those rights is the right to privacy btw.) is fundamental to a healthy functioning family. In turn they should respect your wish to know what they're doing - but not every detail (and you will never find that out anyway).

    I did not understand that point of view at 7, and I do not agree with it a 40-something.

    It seems to go without saying that children are not entitled to privacy from their parents. I say it is up to the individual parent. Many parents DO respect their children enough to give them privacy. Some consider doing otherwise to be a form of abuse.
