When you use the Account Administration tool to configure an application role for an Enterprise account, you can select "Enable Secure Content." If you select this option and publish v30 or later retail folios with the "Encrypt Folio" option selected, the content in those folios becomes secure on iOS devices in the following ways:
- Folios in a secure account are not available through the Folio Producer Service (acrobat.com). Folios are available only when published to the Adobe Distribution Service.
- Retail folios published to the Adobe Distribution Service are encrypted.
- Folios delivered to an app are encrypted.
- When the device is locked or powered off, secure folios remain encrypted. The folios become available after the device is unlocked using a pass code. This feature uses standard iOS functionality provided by the operating system. For more information on secure apps, see Apple's iOS Security document (PDF).
Use this option only if you have confidential or sensitive information in your app. Social sharing, web viewer, and background downloads are not available in a secure account. Use this option only for an app with direct entitlement and retail folios published as v30 or later.
- The app must include direct entitlement.
- Only retail folios can be encrypted.
- Social Sharing via the web viewer is not available.
- Wireless preview of secure folios via Folio Producer is disabled by design. Use Preview on Device or a development app to preview secure folios.
- Background downloading and progressive downloading are not supported. On a device, the entire folio must be downloaded prior to being decrypted.
- At this time, folios are secure only on iOS viewers, not Android or Windows Store.
After signing in to the Adobe Content Viewer, secure folios will not show up in your library as available for download because they are not available through the Folio Producer Service. To preview folios in a secure account, you can use the Preview on Device or Preview on Desktop menu setting from both the Overlay Creator Panel and the Folio Builder Panel in InDesign. Alternatively, you can build a custom app and view folios published as Public and Retail.
Adobe can release security patches as needed to ensure secure content. If a security breach occurs, Adobe will make a new security patch available. Publishers can then specify the newest security patch and deprecate the older version of the app, preventing users from continuing to take advantage of the security breach.
To fix a security breach, Adobe might need to change both server components and the app client. If the security breach requires a new app client, publishers should follow these steps to build a new app version with the newest patch. Users should install the new app version to get security patches. In this case, the app with a new security patch will detect the need for an upgrade and prevent users from downloading additional secure folios.
Use the Account Administration tool to specify the newest security patch, if necessary.
