Preventing Amazon S3 Bandwidth Stealing?

Question

I have a Image Hosting Site that is using Amazon S3 as a main source for bandwith and storage.

I have a few option here to prevent other sources from stealing my bandwith, but I am hoping there are more or other alternatives.

1. Query String Authentication
2. Url Rewrite

Are there better ways to prevent thieves from hot-linking to my Amazon S3 files and using it on their site?

Answer 1

The best way to prevent hot linking is to use new Amazon S3 bucket policy feature. See our blog post on the example of such a policy
