Google Cloud Storage security: restrict bucket access by request domain

Question

How can I setup security with my Google Cloud Storage bucket so that only certain website domains (like my google cloud app) or authenticated users are allowed to download files from the bucket?

Right now download links to files in the bucket are publicly accessible.

You should use the Access Control Lists (ACLs) to grant read or write access to users for individual buckets or objects. Note: Use ACLs only when you need fine-grained control over individual objects.
