Captchas for all the crackers&haxzors

[CaldasGSM]

In a project I'm working on, I need to put a captcha in a page..

Yes I now its a stupid gimick, and yes i know there are porn sites to break them.. and yes I know here are other methods..

but for this particular case I think its the option that works best..

 

But I don't want to be dependent on other services, and services like reCaptha are broken so many times that lately the have become unreadable even by humans.. So I'm trying to make my own..

 

Since the purpose of the captcha is to distinguish humans from computers.. I decided to address things that are unique for humans

1- The illusion or suggestion of images.. in this case letters

2- the way eye processes and merges colors

 

- For the first part, there is actually no letters in the image just their shadow.. so hopefully even if there is no contour or filling of the letters, people will still me able to "imagine" the letter

 

- Second the image is made of little multi-colored dots, but colors are organized so that all of the background seems red

and the letters pop with contrasting colors..

 

 

will I believe this image is still readable.. (except for color blind)

 

computers will have more trouble collecting the blobs of color since the letters are made of many colors

 

and even if they can grad the letter shadows.. there is discontinuity in the marks.. making it hard to perform OCR by conventional means...

 

 

please tell me if is easy or not to crack (but not just fidlling with contrast on photoshpop, test on actual captcha breakers) and tell me how hard it is to break..

 

and give an opinion about this method for captcha images..
