Internet filtering for children (or other reasons) that would actually make sense

[jack]

I was recently debating in another journal about new suggestions for internet filtering, ostensibly to prevent children seeing child-inappropriate sites. This is normally met with -- imho justified -- cries of doom. However, it does seem likely that there would be ways to approach it which would actually do some good -- if you, as a reasonably technical aware person, were proposing something, what would it be?

Suggestions:

* Not support political censorship
* If it requires a large investment of manpower (eg. great firewall) be upfront about where that comes from
* Should fulfil stated purpose of allowing concerned non-technical parents to protect their children from inappropriate content to at least some extent
* Should not be a massive expensive unworkable pointless joke
* Should be clear if it will work a country at a time (probably not) or be a small but incremental improvement over large classes of website.

Whatever the government is thinking about is almost certainly unworkable. But if there were something NOT ridiculous which could be suggested instead, that would actually be better than just "it doesn't work", or at least make clear to people who DO want a solution that it may be expensive.

It might even have positive side effects if (eg) pure spam domain names were caught in the crossfire.

Starting points for debate, suggested by me or others:

* How to rate sites, white-list, black-list, self-rated, automatic, some combination?
* How to filter -- at ISP, on computer, on router? Is it easy to bypass with an appropriate password?
* What is the threat model? How do you transition from a five-year-old who may need constant parental monitoring to a 15-year-old who needs their own privacy?
* What do virgin mobile do, apparently they do some filtering? How comprehensive is google safe search? Is it possible to base something on such an existing list?

I'm pretty sure Google don't have a black list of bad sites. They use some algorithm to remove sites which look like they have may adult content. There are three levels of protection from none, to medium, to strict. Which presumably turns up the aggressiveness of the algorithm.

I don't understand why people think an automated system would be so bad. In practice Google Safe Search is very effective, as is the filtering on my mobile internet.

*in order for safe-search like algorithms to keep away ALL the porn the inevitably catch non-porn in their net.
*if, therefore, you want to get all the non-porn then you are going to end up with some porn
*unless you have a large number of humans check for porn (assuming everyone agrees about what porn *is*)

At present a lot of anti-porn filters also filter out things like non pornographic nudity and factual websites concerning genital anatomy or sexual health. If we have a plan to filter EVERYONE'S internet (unless they specifically say "give me the porn") then people are going to be very upset if they can no longer read articles about breast cancer or buy their underwear on the internet.

Yes there will be a false positive rate with such a system, and if you're tuning it to block a lot of porn then it'll probably block a lot of non-porn as well.

I would expect the proposed system (which will probably never happen, but anyway...) would allow the customer to entirely opt out if they wanted to (like the mobile broadband system) and might even allow you to override on a site by site basis (e.g. "Enter your pin to unlock hotsexygirls.com for 1 hour").

Well, that depends how it works.

If it is meant to be robust against teenagers who are more tech-savvy than their parents (because if the parents were more tech-savvy they would have solved the problem of blocking sites they don't like from their teen's computers already!) then you can't allow the user to disable it from their computer. I imagine the process for turning it off would probably be quite irritating to manage (or it would be functionally useless).

If you are blocking porn because the user has decided themselves that they don't want to see random porn all over the place then you obviously include a "no no I really want to see this one" button. But if you don't want the user to have that power it's harder.

I admit I worry mostly about what non-porn things will end up classified as "not suitable for children". I'm not going to cry over kids not being able to see porn! But kids not being able to access information about sexuality and anatomy would be depressing.

I think any such system would be primarily targeting young children inadvertently coming across porn online. The figure quoted in the commons was that 50% of children have seen pornography by the age of 11, and the example given was that the google search "American girls" is both the name of a series of kids dolls and the name of a porn site that appears on the first page of a google moderate safe search search.

I don't think such a system would be very effective at stopping truly determined late teenagers who are technically proficient (although I think it could make things much harder which probably is a good thing).

I agree it would be fairly pointless for preventing access for adults themselves. I suspect a better implementation might have a "The site is blocked due to being XYZ type of site. To unblock for your internet connection permanently or for X minutes enter your PIN here".

I think there would be some miscategorisation, that's inevitable, but this could be limited. Sites could optionally self certify and such self certification would take precedence over the algorithms categorisation. So a sex ed site could self certify as being non pornographic and so access would be allowed. Of course this is open to abuse, but it sounds like a good compromise to me.

I don't understand why people think an automated system would be so bad.

I remember some school that, as an experiment, used fingerprint scanners to control access. What they did not stop to consider was the first thing anyone else would have asked -- if your scanners work 99.5% of the time, and several thousand people go in and out several times a day, what do you do when the scanner fails to recognise someone?

Apparently they ended up turning the scanners off, because there was always a backlog of people stuck behind someone who couldn't get in, and no consistent procedure for dealing with that.

Your proposal includes being able to selectively bypass the filter for specific sites, which would be a good answer to the problem of "what happens when you want filtering most of the time, but there are constant false positives and negatives?" At least its AN answer. But it seems likely implementing such a system will cost money and time, and everyone will just ignore the possibility and either turn the filtering off or live with it. Which is the problem.

I don't think the average person would probably have the system on. I might but I imagine most people I know would just have the filtering turned off.

It'd pretty much only be of interest to parents who didn't have the savvy to restrict porn on their end (i.e. most parents) who were concerned about their kids accessing porn (i.e. almost all parents).

I haven't found the automated system provided by T-mobile to constantly get in my way, so I guess I find it odd that people expect the proposed system to be entirely unusable because my experience of it (well, what they'd almost certainly used) is that it isn't.

[jack]

Apparently, what almost certain to be proposed is to extend the inconsistent filtering used on most mobile internet accounts (which I never even noticed, oops) to all internet accounts. Which is probably survivable if everyone can turn it off, not too expensive, may be mildly beneficial for households with children, but generally a pile of pointlessness...

Why do you think it's pointless? If I try to access porn on my mobile phone it is actually quite hard to do so. Such a system would prevent children inadvertently coming across porn which would I think be quite a good thing, if 50% of children first view pornography at 11 then I think things that we do that move us towards lowering that number are a good thing especially if the greatest inconvenience such a system poses to non-parents is that they untick a box once.
