Abstract
The disclosure relates to processing content with watermarks to generate watermarked versions. In some aspects, each version may be different. Groups of fragments may be combined to generate a unique stream by pulling fragments from two or more of the groups of fragments. Further, fragmenting may be performed before watermarking, and fragments may be pulled and watermarked upon request.

(canceled)
A method implemented by one or more computing devices, the method comprising:
- based on a number of actual or expected entities requesting content, determining, by at least one of the one or more computing devices, a number of watermarks to apply to the content;
- based on the determined number of watermarks to apply to the content, applying a plurality of watermarks to the content to generate a plurality of watermarked versions, respectively;
- accessing a plurality of fragments of the plurality of watermarked versions;
- and
- transmitting a subset of the plurality of fragments, wherein the subset forms a version of the content.

A system comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause one or more computing devices to:
- based on a number of actual or expected entities requesting content, determine a number of watermarks to apply to the content;
- based on the determined number of watermarks to apply to the content, apply a plurality of watermarks to the content to generate a plurality of watermarked versions, respectively;
- access a plurality of fragments of the plurality of watermarked versions;
- and
- transmit a subset of the plurality of fragments, wherein the subset forms a version of the content.

A method implemented by one or more computing devices, the method comprising:
- based on a number of actual or expected entities requesting content, determining, by at least one of the one or more computing devices, a number of a first plurality of watermarks to apply to the content;
- based on the determined number of the first plurality of watermarks, applying the first plurality of watermarks to the content to generate a first watermarked version;
- based on the number of actual or expected entities requesting content, determining, by the at least one of the one or more computing devices, a number of a second plurality of watermarks to apply to the content;
- based on the determined number of the second plurality of watermarks, applying the second plurality of watermarks to the content to generate a second watermarked version;
- accessing a first group of fragments generated by fragmentation of the first watermarked version;
- accessing a second group of fragments generated by fragmentation of the second watermarked version;
- and
- transmitting fragments, of the first group and the second group, that form the content.
