Meta data/File info?

I'm not sure if those 2 names are the same but I'm still wondering
When you're on Photoshop you can File>File info..., that to me looks like a way to add a credit to your works, the credit would even show up for a .png file. But it seems like there's no way to lock it? If i share my files to somebody else with the Credit/File info thing on, they can still go in and edit it out, aka they can steal my works.
So yeah I'm basically asking if there's anyway to lock the File info/Credit thing 😅
