Is there a way to baffle the CIGaussianblur filter and get the original unblurred image in iOS?

I am uploading a blurred image to my server and download it later on in my app. I then need to un blur that original image. The blur filter is the cigaussianblur filter.

I know I can store the original image along with the blurred image on my server but if I can un blur the blurred image, this would be the better option for me. Any help would be awesome. Thanks!

Well, you can't. The information is lost from the image. If you want to keep the original information, as you rightly say, store the original image. (That, by the way, is how iPhoto / Photos works; it stores the original image along with any edited versions of that image. That is what makes editing operations undoable.)
