If it is true that...

An attacker will need to work hard to repair a large corpus of synthetic media containing locally consistent but globally inconsistent errors

Then it must be true that...

A good method for watermarking synthetic media using an error-ensuring code is to insert errors which are locally consistent but globally inconsistent

If it is true that...

It is easier to create or detect locally consistent but globally inconsistent errors in synthetic media than it is to fix all the errors

Then it must be true that...
