As you know AWS S3 Bucket is used to stored data in a cloud storage container.

While you can define S3 bucket owner, it was difficult to then assign and identify stored data ownership.

Well, now you can automatically apply ownership to stored data based on the S3 bucket ownership.

To do so, logon to your AWS console (https://console.aws.amazon.com/) and access your S3 bucket

Then access the bucket you want to define data ownership based on the bucket ownership to access the Permissions tab

There access the Object Ownership option to edit the ownership to Bucket owner preferred

If you want to enforce this option, you can update your bucket policy to ensure the PUT request includes the bucket-owner-full-control canned ACL (for more details see https://docs.aws.amazon.com/AmazonS3/latest/dev/about-object-ownership.html#ensure-object-ownership).
