MediaDrm provisioning

As on ChromeOS, the internet site may request verification that the device is entitled to achieve this. This is certainly achieved by MediaDrm provisioning. A provisioning demand is sent to yahoo, which produces a certificate which is put on unit and provided for your website once you bring safeguarded content. The info from inside the provisioning consult and also in the certificate vary with respect to the Android os type. In most circumstances, the information may be used to recognize the device, but never the user.

On Android os K and L, the product just needs to be provisioned when therefore the certification is actually provided by all applications operating on the product. The demand contains a hardware ID, additionally the certificate contains a steady tool ID, each of which may be used to forever identify these devices.

On Android M or later on, MediaDrm aids per-origin provisioning. Chrome arbitrarily generates an origin ID for each and every web site to end up being provisioned.

On Android models with per-origin provisioning, Chrome pre-provisions alone once the consumer attempts to perform shielded contents. Because provisioning for any first playback currently engaging sending a reliable components ID to Bing, the next pre-provisioning of added beginning IDs introduces no latest confidentiality effects. If provisioning fails and there’s no pre-provisioned origin ID, Chrome may inquire about approval to advance fallback to per-device provisioning.
