APPLICATION DESIGN
Hiding fields is not a security feature. Users can see the value of hidden fields on the Fields tab of the Document Properties box in the IBM® Lotus® Notes® client. To keep the data fields safe, encrypt, rather than hide, the fields.
Hiding options
When you hide a field, you are actually hiding the paragraph on the form that contains the field. If there is text, such as a field label or graphics, in that paragraph, Designer hides them with the field. You can hide a field and any associated text or graphic all the time or only at certain times. For example, information useful only when users create or edit documents can be hidden during reading, printing, and copying; information that is used for display, such as a computed field that displays the result of an author's choice in an editable choice list field, can be hidden during editing.
The following are options for hiding fields:
Information is hidden when the application opens on a Notes 4.6 workstation.
The information is hidden when the application opens on a Web browser.
The information is hidden for Mobile users.
