Hi.
I agree with Andre, you can't make a captcha that will not be usable by
blinds, it's called discrimination; this list is, to my mind, not only
about i18n, but also about accessibility, because both go together.

Hello Aalekh,
Just note please that none of your 6 solutions is accessible for blind
and visually impaired users.
We are quite numerous in this world, so if you are absolutely sure
that you haven't and won't have any blind users on your projects, you
might do that. But if not, these solutions are just inacceptable.
Sorry and thanks.

Subject: [Mediawiki-i18n] Captcha Idea Proposal for GSOC 2014
Hello,
I am interested in Multilingual, usable and effective captchas
project listed
in https://www.mediawiki.org/wiki/Summer_of_Code_2014and figured
out few solutions to encounter the solution
Way we can approach the project:
1)Alphabetical order captcha:We can use Html5's drag and drop Api to list
a particular Set of images into one category .for example in the example
mentoined in the demo here ,i made a collection of diff words
starting with letters A,B,C ....as an output i grouped up words with
starting letter A diff from words with starting letter B,C....As,i used
text in this example we can use images of diff animals such as cat's and
dog.....and by drag and drop we can group images of cat and that of dog in
diff categories.
2)Annotation captcha:We can use Images With annotations from
commons determine the subcategoriy the annotations belongs to and then give
relevant options to the users ;for example in the file we can search from
names of different annotations to which they corresponds to from
wikipedia(names given here are those of mountain) and then give the the
option's much relevant to the image.
3)Effect captcha:We can use image as a question which are changed by the
effect produced php's gd library and the use the same file with another
effect and then ask user to match the two files.....for
example:the image1 can be used as a question asking user to click
on the image that matches with the question image and as an answer we can
give this spiral image of the original image.Similarly we can
give filters to different images producing different options asking user
for right answer.
4)Direct captcha:We can ask to user direct questions like ask for
selecting cat out of options consisting of images of cats and humans.....an
example by pginer demonstrate this example
5)Ask User to click on given effect: Asking user to click on images
consisting of spiral effect's out of options which consist of images with
spiral and other effects(example:grey scale).
6)Drag and Drop character in Correct Place: We can use drag and drop api
of html5 to ask user to form an particular alphabet or no out of the pieces
of character provided .Here is an example to form an character
"A" and an digit "8" out of the same pieces of character.
This drag and drop capability can be further enhance to form a particular
shapes.For example form a clip art from a particular set of piece of
shapes....for example the image given here inserts the correct nose as
asked in the in the questions out of the possible options provided.
Most,Importantly i think creation of an index system would be fruitful
since it would rank the inappropriate images on the basis of users response
(rank is negative for an image if user needs to reload a captcha) to a
provided captcha.This as the time passes will provide us with relevant
images which are user friendly and equivalently secure to use.......
In addition i sincerely appreciate a point mentioned by Gmansi of creation
of jigsaw puzzle for the images but in my view point there will be listing
of some particular category of images and those ranked higher in indexing
system to be used as jigsaw puzzle.
As an additonal help we can use Extension Assira to make our
extension smarter.
I request all members to please give your valuable suggestions as we can
work to improve this amazing project. at
