How do you let only authorized user have access contents stored in Amazon's S3?

Question

Once you stored contents in S3 and make it public, then everyone have access to it. Is there a way to let only authorized users have access to the content stored in S3? For exam

Answer 1

You want to read the section called 'Query String Request Authentication Alternative' found here

It explains how to create a time-based expiring link to an S3 object

You would then have to write the code that manages the users (the who owns which object part of your question).
