I figured out following 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.
please give your valuable suggestions as we can work to improve this amazing
project. at https://www.mediawiki.org/wiki/Talk:CAPTCHA :)
