Discussion: Ajax and privacy
Posted on 2006-05-16
Currently we see the implementations of AJAX to become more popular and popping up everywhere.
One of the things - i personally find somewhat useless btw - is to use AJAX to run validation on form fields.
Implementing auto-completion on form fields sounds sensible, but using AJAX to validate emailaddresses seems silly and waste of bandwidth. This however is not my point.
The thing I am wondering about is whether or not privacy might become an issue, in cases like above forms.
In essence the AJAX forms submit personal details to servers, before people themself "give consent" by pressing a submit-button. Although most of the time AJAX will be implemented without any malicious intends, there will always be those sites that use the technology in other ways. From webbrowser/implementation point of view it is quite hard (if not impossible) to determine wether or not a AJAX implementation is transferring search terms, or emailaddresses, creditcard numbers and other personal details.
My question therefor is: Is there a change that, in the forseeable future, AJAX can be banned/limited by because of privacy issues involved.
Also, which limitation should we be anticipating for? (Ie, can AJAX be limited at all, or is it a all-or-nothing kind of situation?)
