    Find Pornographic Images on Home Areas

    I've just been on a trawl for games in home areas and with a combination of software restriction policies and aggressive removal of *.bat, *.vbs, *.exe files to a holding area (in case any do turn out to be legit) feel I've got a handle on that problem.

    What I have noticed though is some students were stupidly "hiding" game files in their My Pictures folders with topless or nude photos.

    Clearly I am concerned that students who bring in files from home may choose to store them on their home areas and, even though the images were downloaded at home, the backlash from parents will be unpleasant.

    I must also accept that despite the best efforts of EMBC and Tom at Smoothwall some images will get through from time to time.

    As such it'd be great if we could scan for images that contain a high skin tone percentage. I acept this may have limited usefulness with non caucasian models but would at least mean we were being proactive in policing the issue.

    Do you use any software in your school that does this? Would you recommend it?

    What issues have you found doing this or have you ever been bitten for not doing so?

    we have securus but have yet to properly implement it. when used correctly it has a skintone/boob image detector. wen we were shown it it did get confused by bald men but they were working on it at that time.

    The software to do this is patchy at best and usually integrated into stuff like web filtering, the one thing that I could find that looked promising was this

    http://www.yangsky.com/products/porndel/index.htm

    Warning - cotains filtered demo images that are still unsafe for work

    I have not used it but it could work.

    There is, yes, but it won't scan for specific image types, or at least it didn't when I used it. (Nudity etc)

    We have mandatory profiles so they can't save anything locally or anything in their profile, they have network shares to save work which are only 5mb so they either save work or nothing at all, they also have restrictions to what they can save on them, no pictures video, applications ect.
    They can't even right click.

    I think the first thing you should do is lock down profiles so they can no longer store stuff in them.

    We also have a 8e6 content filter which does a great job.

    Lock 'em down they cannot be trusted.

    cor the students here are complaining they only get upto 1gb in year 12/13 (year 7's get 200mb) how can you do it with only 5mb or is it a typo? we have students with one word doc thats bigger then that!

    sorry to take it off track!

    But we use securus aswell (when its on as it is currently off) but that seems to pick up alot of stuff, or by the time its processed what was on the screen the snapshot is of the desktop!

    Not a typo, they are advised to use only text and not pictures.
    It's plenty of space if they're responsible.
    We really don't have the time to babysit them.
    As much as administration, teachers and parents would like us to.

    ANFS has been withdrawn with the source being provided to EduGeek so it can be further worked upon, both anfs and EduSweep will do file search but do not have the ability to scan images for flesh tones in order to distinguish if an image is of a pornograhic nature.

    Any software you find to do this will cost you, and it won't be cheap.

    we have a problem here that part of the coursework requires screen shots so we cannot say no photo's, also we have lots of music suites so there are normally quite a few sound files which are quite large

    Yes I'm sure I'd be in the same situation provided the staff and students use all the software to give to them, but lets just say they aren't that "advanced" and usually stick to word and don't bother learning how to use anything else let alone teach it... I am quite lucky in this way.

    Is this actually that difficult? It'd be dead easy to write something to search through a bunch of folders, thumbnail any images found and shove them on to an HTML page. You could try sorting them in order of amount of "skin" colours found in the image, just a simple average. It'd need someone to visually check things over once a week, say, but it should be easy enough to spot anything dodgy quite quickly.

    Talking

    Our head has a very effective way of preventing these kind of images, whenever we happen to come accross a pupil with shall we say inappropriate images on. I have to print them off and give the to the head along with pupils name, date they were found etc.
    The Head then sticks them in an envelope, along with a covering letter asking the offending parties parents to come in and discuss what we have found.
    I have been here four years and only needed do this twice, word very quickly spreads and mass deletions take place. Lol.
    I highly recommend it, if you really are having a problem with it.
