You can create any number of policies by using security
settings that are appropriate for different situations and users.
Policy attributesWhen
creating a new policy, you set various policy attributes, such as
the policy name. If you are using the LiveCycle SDK or the Rights
Management web pages to create the policy, you can also set a validity
period for the policy. A validity period is the time period
during which a policy-protected document is accessible to authorized
recipients. If you do not set this attribute, the policy is always
valid.
A validity period can be set to one of these options:
A set number of days that the document is accessible from
the time it is published
An end date after which the document is not accessible
A specific date range for which the document is accessible
Always valid
You can specify only a start
date, which results in the policy being valid after the start date.
If you specify just an end date, the policy is valid until the end
date.
You can also create a policy that applies a dynamic
watermark to PDF documents. Watermarks help ensure the security
of a PDF document by uniquely identifying the document and controlling
copyright infringement. These dynamic watermarks are different from
the static watermarks that you can apply on PDF documents from Acrobat.
You
can define dynamic watermarks that consist of multiple watermark elements,
each containing text or a PDF. The text that is displayed in the watermark
can be any of these:
- User name:
- The name of the user who opened the document
- User ID:
- The ID of the user who opened the document
- Policy name:
- The name of the policy that is assigned to the document
- Current date:
- The date the document was opened
- Custom text:
- Text, such as the word Confidential
You can
define the appearance of the text, such as font, font size, and background
color.
With a PDF document as the watermark element, you
can include logos or special graphic indicators. For both text and
PDF watermark elements, you can specify the scaling, positioning
on the document, and the dynamic range of pages where the watermark
should be applied. For example, you can have the watermark appearing
on all pages of the documents, regardless of the number of pages.
After
a watermark is created, you can include it as part of a policy.
After a policy that contains a watermark is applied to a PDF document,
the watermark appears on each page of the policy-protected document.
Policy entryA policy entry attaches principals, which are groups
and users, and permissions to a policy. A policy must have at least
one policy entry. Assume, for example, that you perform these tasks:
Create a policy entry that lets a group view a document only
while online and prohibits recipients from copying it
Attach the policy entry to the policy
Use the policy to secure a document
As a
result of these actions, recipients can view the document only online
and cannot copy it. The document remains secure until security is
removed from it.
Methods for creating policiesUsers and administrators
can use the Rights Management web pages. (See “Creating and editing
policies” in Rights Management Help or LiveCycle Administration Help.)
Use Workbench to create a policy from an existing policy.
When you create a policy in Workbench, there are fewer properties
to configure. (See Workbench Help.)
Use the Rights Management Service API. (See Programming with LiveCycle.)
