Captcha security test questioned
Is Captcha security a good idea? is a question has been raised as a result of problems with a White House petition.
The fact that Ticketmaster dumped the Captcha from their website casts further doubt on the need for this security measure.
Is Captcha security a good idea?
The National Federation for the Blind in the USA has stated that its members are unable to sign an e-petition which is collecting support for demands that printed material should be more accessible to those who are visually impaired because of “Captcha” security on the website.
A Captcha is a graphic of a random word or numbers users must key in to show that they are human.
There is an equivalent audio version on most websites that feature the Captcha.
Captcha comes from ‘Completely Automated Public Turing Test to Tell Computers and Humans Apart’, so one could argue its two or three t’s short of an accurate Acronym.
The White House whose website it is says that it complies with official US accessibility standards although it has received just 8,200 signatures.
Chris Danielsen of the American Federation for the Blind said “We had asked people to sign the petition and we’re getting these emails saying that people can’t”
He told the Politico website that he realised there was a problem after he began publicising the petition.
The editor of the BBC’s ‘Ouch’ blog (for people with disabilities) Damon Rose said that “Captcha graphics are a nightmare – visually impaired people use screen readers to interpret their computer rather than their eyes and the screens can’t manage them.
“Ironically if I see an audio capture I tend not to bother with it because it’s usually such a poor experience… some of them sound like aliens talking and they put weird background noises over them. They are a bit of a joke in the blind community. I’ve spent half an hour on some and had to give up.”
Mr Rose added that a result of this was that many visually impaired people found that, on messageboards and blogs they could not contribute to discussion and debate.
Earlier the year Ticketmaster the international event ticket service removed the Captchas from its sales website.
Aaron Young of Bunnyfoot, the user experience consultancy said “It is generally speaking the one of the most hated pieces of user interaction on the web,”
In the view of Irish Web Design it is worth weighing up the value of the added security versus the irritation to users that Captcha causes.
Your business may be losing customers who simply give up when confronted with the frustration of a difficult to read Captcha.
So in response to the question: ‘Is Captcha security a good idea?’ Irish Web Design feels that in many cases it is not necessary, and therefore is not a good idea.
