Working with private entries
In most applications you can mark individual entries as private. All private entries remain visible and accessible until you select the Security setting to hide or mask them. When you hide entries, they do not appear anywhere in the application. When you mask entries, a visual placeholder appears where the entry would normally appear. If you define a system password, you must enter it to display private entries. If you do not define a system password, you (or anyone else) can reveal private entries without a password.
1.Display the entry that you want to mark private.
2.Select Details.
3.Check the Private box.
4.Select OK.
Hiding or masking all private records
Make sure the entries you want to mask are marked private.
1.Go to Applications 
and select Security 
.
2.Select the Current Privacy pick list and select either Hide Records or Mask Records.
As a security measure, masked Contacts entries are temporarily hidden when you perform a search. So, you will not see a placeholder for masked entries when viewing the results of a Lookup or Find request.
