IOS with Rails Backend Amazon S3 direct upload

I am currently trying to use amazon s3 for uploading images from IOS app with a Rails Back-end.

I currently don't understand how security works. In their docs

http://ift.tt/1xNuskg

it's not clear to me how to upload/destroy safely objects in sync with the back-end. For instance, in order to post/destroy, I was expecting a mechanism of asking a signature to the Rails server, and only then be able to upload the image to amazon. But I can't find this kind of mechanism.

Has someone gone through this kind with aws?
