What are com.sec.android.provider.* apps exactly?

Question

I know it's not a code question. However, i try to work on some databases that stored in directories like /data/data/com.sec.android.provider.*.

What does it mean by "sec" in the provider signature? Does it depend on the manufacture provider?

One example: the content provider for call_logs reads the database in /data/data/com.sec.android.provider.logsprovider on a Samsung. What read the same content provider on an HTC?

Im a bit confused...

Those are not part of the Android SDK.

Samsung Electronics Corporation is my guess.
