And to id's point, I think CAPTCHAs do provide a service, just not the one that most people think it provides.

The only place where I can see them being worthwhile at this point is as an anti-annoyance measure.

it can work for more than just landmarks. show famous people. show famous paintings and require the name of the artist. etc.

Single object is easier to decode as the bot could use outline matching, unless you have a huge variety of object. Say, many different design & shape of houses could make it a little tougher but it is not impossible to train the bot to learn it all.

There are couple of reports published by those "experts" explained pretty well about captcha weakness. Run a search on google, not many sites out there on this.

To me, it is blurring/dotted/light/overlapping/guessing that make the bot dumber than human.]]> wi1s0n Robots/Spiders/CAPTCHAs, oh my Mon, 09 Jul 2007 05:05:29 -0500 http://sla.ckers.org/forum/read.php?7,3549,7796#msg-7796 Re: PWNTCHA Code http://sla.ckers.org/forum/read.php?7,3549,7796#msg-7796 rsnake Robots/Spiders/CAPTCHAs, oh my Fri, 09 Mar 2007 12:30:01 -0600 http://sla.ckers.org/forum/read.php?7,3549,7674#msg-7674 Re: PWNTCHA Code http://sla.ckers.org/forum/read.php?7,3549,7674#msg-7674 SW Robots/Spiders/CAPTCHAs, oh my Tue, 06 Mar 2007 19:41:37 -0600 http://sla.ckers.org/forum/read.php?7,3549,7661#msg-7661 Re: PWNTCHA Code http://sla.ckers.org/forum/read.php?7,3549,7661#msg-7661 rsnake Robots/Spiders/CAPTCHAs, oh my Tue, 06 Mar 2007 16:32:50 -0600 http://sla.ckers.org/forum/read.php?7,3549,7649#msg-7649 Re: PWNTCHA Code http://sla.ckers.org/forum/read.php?7,3549,7649#msg-7649 -------------------------------------------------------

That is a good idea I think.

How about like a matching game -- You can list all the words with numbers and they have to put the numbers in order. Like so:

|pic0||pic1||pic2||pic3||pic4||pic5||pic6||pic7||pic8||pic9|

Enter numbers that correspond with images from left to right: __________

0. penis
1. house
2. car
3. banana
4. apple
5. bike
6. ocean
7. china
8. flower
9. paper

ETC. And then you would just have to combat stupid people who don't know what a banana is.]]> SW Robots/Spiders/CAPTCHAs, oh my Tue, 06 Mar 2007 13:00:46 -0600 http://sla.ckers.org/forum/read.php?7,3549,7269#msg-7269 Re: PWNTCHA Code http://sla.ckers.org/forum/read.php?7,3549,7269#msg-7269 rsnake Robots/Spiders/CAPTCHAs, oh my Thu, 22 Feb 2007 23:42:35 -0600 http://sla.ckers.org/forum/read.php?7,3549,7139#msg-7139 Re: PWNTCHA Code http://sla.ckers.org/forum/read.php?7,3549,7139#msg-7139 marko Robots/Spiders/CAPTCHAs, oh my Wed, 21 Feb 2007 00:49:04 -0600 http://sla.ckers.org/forum/read.php?7,3549,5635#msg-5635 Re: PWNTCHA Code http://sla.ckers.org/forum/read.php?7,3549,5635#msg-5635

jungsonn, your solution should work, as would creating a custom text image, as long as it's not too similair to an existing popular image. Flying under the radar is a good method to bypass PWNTCHA imo, for now anyway. I know Gadi Evron has put major effort into trying to create a good CAPTCHA with some neat ideas.

I've created a very simple PWNTCHA thing myself, but it really is so bad I'm ebarassed over it. I don't know of a better solution. I've noticed that there is some great OCR software out there, but I never managed to link that into anything. That was a while ago though, before I knew what I know now. Maybe I should give it another crack sometime soon.]]> WhiteAcid Robots/Spiders/CAPTCHAs, oh my Fri, 01 Dec 2006 22:24:05 -0600 http://sla.ckers.org/forum/read.php?7,3549,3608#msg-3608 Re: PWNTCHA Code http://sla.ckers.org/forum/read.php?7,3549,3608#msg-3608
and you don't own the language.. if anything germany owns it. and french/spanish/italian would all be latin bastardizations _-_

and back on topic, i think if you implemented it for your own site it'll work well jungsonn. as long as it's used on a small scale people won't bother to write a decryption for it. Kinda like mac's security via low market share. But, i dunno how much more programming difficulty it presents over letters.

people clearly just don't think alike. what some call a bike, others call bicycle, house/home/building, car/vehicle/automobile/civic/coupe/sedan/auto .. not to mention other languages. maison/arbre/velo for frenchies _-_ .. and those crazy brits with all their retarded nicknames for things. (sorry, but it's true)

and as a side tidbit.. object recognition in images is alive and well .. and a big aspect of Digital Signal Processing. For example: http://www.public.iastate.edu/~knutzonj/ee424projectMain.htm which talks about a couple techniques.

I agree it's significantly harder for computers.. but it's also much harder for humans to pick the right words. You'll need a human to verify that the answers are something a human would guess .-.
