This is not the correct way to synchronize two databases.

How will it help you to know the binary diff? You will not be able to do anything with this information.

I see. You don't want to synchronize two databases, you want to only apply the changes from one database to another. How large are your databases?

I think that it will be simpler to make a query for all the updated results and then add them to the second database. Working with 400mb files on the device can be a slow task.
