Report data security on mobile devices
All compiled and compressed versions of IBM® Cognos® BI
reports are encrypted and stored locally in the mobile encrypted database
of the mobile device. These reports can be read or otherwise interpreted
only by the IBM Cognos Mobile client application.
You can use lease key technology to set an expiry time for report data that is stored on the mobile device. After the expiry time, the report data cannot be accessed on the device until the device can reestablish communications with the server, and the user is able to re-authenticate with the server.
If a device PIN is configured on an iOS device, the IBM Cognos Mobile application encrypts the manually imported Cognos active reports that are stored on the device. This feature applies to active reports that are manually imported through email, iTunes, or a file server.
