MediaDrm provisioning
As on ChromeOS, the web site may ask verification the device is entitled to do this. This is certainly accomplished by MediaDrm provisioning. A provisioning demand is sent to Bing, which yields a certificate that’ll be retained throughout the unit and provided for the site when you perform covered contents. The info into the provisioning request plus the certification differ depending on the Android os version. Throughout circumstances, the knowledge can help identify the unit, but never ever an individual.
On Android K and L, the device only must be provisioned when in addition to certificate try contributed by all software running on these devices. The demand have a hardware ID, together with certification consists of a stable tool ID, each of which could be used to forever decide the unit.
On Android os M or afterwards, MediaDrm supporting per-origin provisioning. Chrome arbitrarily builds an origin ID for every single website to getting provisioned. Although the consult however includes a hardware ID, the certification varies each site, in order for different web sites cannot cross-reference equivalent unit.
On Android os O or later on some products, provisioning can be scoped to one application. The request will have an equipment ID, however the certification will be different for every software, along with each site, very various applications cannot cross-reference exactly the same unit.
Provisioning can be subject to the a€?Protected mediaa€? approval from inside the a€?Site configurationsa€? eating plan. On Android os forms K and L, Chrome will usually ask you to grant this permission before provisioning starts. On future variations of Android os, this authorization try provided automagically. You can clear the provisioned certificates whenever utilising the a€?Cookies along with other website dataa€? option in evident browsing data dialog.
Chrome furthermore carries out MediaDrm pre-provisioning to guide playback of protected material in cases where the provisioning machine is certainly not obtainable, such as for example in-flight recreation. Chrome randomly generates a list of origin IDs and provision all of them in advance for potential usage.
On Android variations with per-device provisioning, in which provisioning need a permission, Chrome will not supporting pre-provisioning. Playback might continue to work because the product might have already been provisioned by more applications.
On Android versions with per-origin provisioning, Chrome pre-provisions it self when the individual tries to bring covered articles. While the provisioning the earliest playback currently involved delivering a steady components ID to Bing, the following pre-provisioning of added beginnings IDs introduces no brand-new confidentiality effects. If provisioning fails and there’s no pre-provisioned source ID, Chrome may inquire about authorization to help expand fallback to per-device provisioning.
