Edit Content with out seeing the information in text box Let me explain this.
Lets say you have a form that you fill out to create a record.

In order to fill this form out you have to be registered and signed in.
Any one can sign up.

This form includes couple peoples addresses and names.

Now any one can go and edit the form where they can see the info on the form.

The problem is that when the form is filled out the first time or edited there is some fields that have personal information and i dont want public to see this data.

Does any one have idea how i can hide the information but have the info available to be updated if needed.

I was thinking using password type but it hides all of it.

Or maybe hiding part of the text ? 

I have no idea how to go about this. If any one that reads this has any idea please let me know.

Thanks in advance.
You can use the Field Permissions module to enable create/edit/view permissions per role.  So you can remove the view permission on those fields you want to hide for all roles but the admin role. That way authenticated users cannot view or edit the fields but the admin can.
