Creating DRM Workflows - Part 1 - Content Encryption

In the coming weeks we are going to be presenting a six part series titled “Creating a DRM Workflow” authored by our CEO and Founder, Christopher Levy.

CREATING A DRM WORKFLOW: PART 1

By: Christopher Levy | CEO |  BuyDRM

Deploying a DRM solution can be broken down into two major block processes; encrypting or “packaging” your content and decrypting it and playing it back. This lock and key arrangement is in place in literally thousands of locations in your daily life whether it be an ATM validating your debit card or your car door opening when you push the button on the remote.

DRM systems enable the preservation of content owners’ rights wherever the content travels acting as a portable digital media firewall. To view the content the user must be capable of receiving a license key to unlock the video files before playing them back.  This license key typically has the content owner or licensee’s digital rights expressed inside of it as rights objects. This entire secure process typically happens in less than a second.

To begin let’s look at the first step in creating a DRM workflow: Content Encryption. All content managed by an IP-based DRM system must be encrypted using the specifications designed by the DRM OEM. In the modern marketplace most solutions use a variety of technologies designed around 128 bit AES encryption using either CBC or CTR modes.

Typically a DRM provider will provide Encryption tools which are developed by the provider for use by their customers. In doing so these tools use a variety of common and proprietary technologies to format, encrypt and output the packaged content. In some cases companies use hardening technologies to ensure the security of these tools i.e. the keys they contain and how they got them and how they are using them, is not compromised.

The most common form of these tools is a command line interface packager that provides the simplest method of packaging content with modern DRM. CLI tools can provide a quick and dirty method to rapidly test packaging platforms or confirm format compatibility. They can also be scripted to work in an automated fashion. CLI tools should not be used in a full-ramped up production environment due to their lack of complexity, support hooks, error messaging etc.

Next up are conventional server side tools which provide content encryption. Typically these tools will also provide the chunking, fragmenting or muxing necessary to prepare a conventional input format like MP4 for packaging into a more typical adaptive bit rate (ABR) streaming file. Additionally, a server side encryption product will more often than not support cueing, parallel packaging, more advanced API calls, greater scalability and greater security.

These products are also more likely to include better monitoring hooks and the ability to create custom error messages as well as including more complex logging functions. These tools are the mainstay of the DRM industry and every DRM provider in the industry provides something of this sort. Typically these products are designed for ultra-fast HDD’s and in most cases the hard disk drives are the bottleneck with regards to reaching theoretical limits associated with encryption.

As the cloud becomes a greater factor in large-scale digital media deployments, more and more DRM vendors are adapting their technology to enable cloud-based encryption.  In some cases cloud encoding companies and cloud media companies have implemented their own versions of content encryption within their media workflows. We will discuss that in a later episode.  There is clear progress though with regards to existing DRM vendors adapting their technology to run in the most popular clouds.  For example, when you deploy in Amazon Web Services, the technology must be converted into an Amazon Machine Image (AMI). This AMI is then provided to the customer who can deploy it within their own Amazon Web Services account.

-Next week we will discuss 3rd Party Encoding solutions which support Content Encryption / DRM.-
