eBook/PDF Licence Information
Access to DRM (Digital Rights Management) controlled content is managed by licences defined by the content owner together with general device policies. Please see our restrictions below:
Concurrent Active Devices
Our current DRM licence for eBooks/PDFs is 6 devices. To use a new device after this limit is reached, an older device needs to be de-authorised and cannot be used to access the content after this. This limitation prevents users from sharing their accounts with groups of people to grant them access to the purchased content while allowing legitimate customers to use multiple devices for the content.
Maximum Annual Device Authentications
The maximum number of times that devices can be authorised is set to 10 per year. This means this limit is reached once a certain number of devices have been authorised for a certain user account irrespective of whether or not some or all devices have been de-authorised again. So it is possible to reach the “Maximum annual devices” without reaching the “Maximum concurrent devices” or “content licenses”. This limitation prevents fraudulent users from sharing their accounts and de-authorising their devices after consumption while still allowing legitimate customers to use up to 6 different devices (while not exceeding other limitations such as the concurrently active licences and maximum concurrent devices). Once the maximum annual device authentications are reached, the user has to wait until the annual time frame from the first authenticated device from one year back is reached so a new device can be authenticated.
Export and Print Options
Under the current licence, the DRM protected ebooks/PDFs are restricted to ensure they cannot be exported or printed.
De/Re-authorisation Lockout Time
This is the time frame a device cannot be re-authorised after being de-authorised. Enforcing this time frame prevents fraudulent users to “bounce” content licences with limitations on concurrently active devices between two or more devices by de-authorising the currently not in-use devices only to re-authorise them on use. Currently the de/re-authorisation lockout time is set to 12 hours.
