Monetization strategies require content owners to protect their assets from viral distribution. Highwinds gives content providers the ability to create delivery business rules enforced by the CDN using content protection.
With Highwinds content protection products, end users must view the media through the workflow designated by the publisher.
Website content protection allows content providers to restrict access to content on the CDN using a variety of methods. By default, permissions for content on the CDN are inherited from the parent folder.
This means that if you apply a protection policy to one of the root product-level folders it will apply automatically to all objects in any subfolders. Note that multiple security rules may be active on a folder’s contents at the same time to provide additional security.
URL signing is the most popular content protection product offered by Highwinds. CDN account owners use this product to publish content with a query string parameter token that includes a URL expiration timestamp.
This token is created by the customer’s origin server, and can be used to create unique publishing URLs for each end user request.
URL signing prevents free distribution of content outside the workflow designated by the publisher:
- If an end user tampers with the URL, their request for CDN content is denied.
- If a well formatted URL has an expiration timestamp in the past, end users request for CDN content is denied.
Some other popular content protection policies include:
- Time to Live (ttl)
- Geographic Restrictions (authGeo)
- Basic Authentication (authHttpBasic)
- URL Signature Parameter (tokenField)
- Expiration Parameter (expiresField)
