RE: Accessibility for trustworthiness indicators

Screen Reading programs generally have the ability to tell the user what color something is. However, you have to do specific things to find this out, and most people either don't do them, or don't know how. The defaults don't give you color information.

However, I would also say that sighted people are remarkably unobservant as a whole, and I suspect most of them miss color cues too.  Any system that just relies on color to convey meaning is going to be lost on someone, and that doesn't even consider people who are color blind.  

While your concern is appreciated, you should concentrate on making a universal system that meets the needs of everyone out of the box. And ... if there is information that browsers are not passing along to us, then you as content developers should pressure them!

Subject: Accessibility for trustworthiness indicators


I'm working on phishing prevention, and am concerned with accessibility for people with disabilities. I'm afraid but many security information, e.g., address bar colored green, is really important for distinguishing legitimate sites, but individuals with visual impairment are hard to recognize it.

My team has interviewed with people with disabilities, and found the current screen reader applications are not so efficient to prevent phishing. This was briefly summarized and available at my github repo as follows:

Does anyone have information for protecting individuals with
visual impairments from phishing attacks?
