Use command SIGNSTYLES, using this command you can update the name of Modifier and date modified.
if you want to update the same for creator and created date you should use ACAD template and dump all your standards and styles in ACAD template and use command SIGNSTYLES to add required name.
By default name will be shown your computer name.
how ever cant lock the name of modifier and date but still you can use template reference option into the drawings so that cant update the same.
You can find some commands here which may helps you better.
