Grrr I am getting thoroughly sick of those sites which protect themselves by asking you to tap in a code shown onscreen in a little box, then do their best to disguise that code not only from automated incursions, but from mere mortals!

Some of these are so hard to read, you end up entering the code wrong time and again. There are a couple I have seen recently where I defy anyone with less than eagle eyesight to work out what is in there amidst the jumble of pseudo-letters and almost-numbers. or where a 1 looks llike an i, or a capital Z like a lower-case z, etc etc

Or is it just my aged eyesight? Mad

I hear you on that. Those things are called captchas. There's even a rudimentary one here on trinity for logging in. Whil the one here is fairly simple, others are more complex. The actual reason is that hackers/spammers have gotten much smarter over the years and have figured out how to use OCR on those little captcha images to get the codes! While very cool, it sucks since now captcha designers start needing to make their images in such a way that they cannot be read by OCR routines incluidng using funky colors, shapes, etc. They tend to be rather illegible to me as well (depending on the algorithm) and they certainly aren't any kind of accessible either. Someday the holy grail of something that's easy for humans and difficult for computers will be found, but I've certainly not seen it yet Smile

My favorite so far is the one blogspot uses for people who allow non-Blogger-account people to comment on their blogs; the word won't display unless you allow cookies from www.blogger.com, and there's no indication at all that it is the case... Razz

Thanks ed. I checked out that wiki. I got 2 major things out of it:

1. An acknowledgement that what I was complaining about is a real problem, and not just my aged eyes/brain:
"Even for perfectly sighted individuals, new generations of graphical CAPTCHAs, designed to overcome sophisticated recognition software, can be very hard or impossible to read."
2. The wiki page is half taken up with information and virtual how-to's about how you can defeat the catptchas!! Sheesh! What sort of guys are writing [those bits of] the wiki?

Peter,

I'm with you on this. If I can't read the "secret code" I can't access the site. There are some sites I can't so I don't visit them. Crying or Very sad

This could be used to restrict the access to a website, making it available to hackers only Very Happy
