MediaDrm provisioning

As on ChromeOS, the website may inquire confirmation that the product is entitled to do this. This is certainly achieved by MediaDrm provisioning. A provisioning demand is distributed to yahoo, which stimulates a certificate that’ll be saved on device and provided for your website once you bring covered contents. The information when you look at the provisioning demand plus the certificate change according to the Android os version. In every cases, the knowledge can be used to determine these devices, but never ever the consumer.

On Android K and L, the product merely should be provisioned when therefore the certificate was provided by all applications running on the device. The consult includes a hardware ID, and also the certificate have a well balanced equipment ID, both of which could be employed to completely determine the product.

On Android os M or later, MediaDrm aids per-origin provisioning. Chrome arbitrarily makes an origin ID for each web site to be provisioned. Although the demand still consists of a hardware ID, the certificate differs from the others for every web site, making sure that different web sites cannot cross-reference the exact same tool.

On Android O or afterwards some units, provisioning may be scoped to a single program. The request will have a devices ID, nevertheless certificate changes for every single application, and each web site, so different applications cannot cross-reference similar device.

Provisioning tends to be controlled by the a€?Protected mediaa€? authorization for the a€?Site setupa€? menu. On Android os models K and L, Chrome will usually ask you to grant this authorization before provisioning begins. On later variations of Android, this approval is actually granted automagically. You’ll clear the provisioned certificates any time making use of the a€?Cookies as well as other web site dataa€? alternative from inside the evident searching data dialog.

Chrome also executes MediaDrm pre-provisioning to guide playback of covered material in situations where the provisioning host is certainly not accessible, particularly in-flight amusement. Chrome randomly creates a listing of beginning IDs and supply them ahead for potential use.

On Android os forms with per-device provisioning, where provisioning need a permission, Chrome does not help pre-provisioning. Playback might still work since device could have already been provisioned by other solutions.

On Android os forms with per-origin provisioning, Chrome pre-provisions it self the moment the user tries to bring secure contents. As the provisioning your very first playback already engaging sending a well balanced devices ID to Bing, the next pre-provisioning of additional beginning IDs present no new confidentiality implications. If provisioning fails as there are no pre-provisioned beginnings ID, Chrome may ask for permission to further fallback to per-device provisioning.
