Abstract
Described herein are systems and methods for obfuscating variants of content segments. Variants of content segments can be used to encode an identifying sequence in a transmission of content. The duration parameter of a manifest entry can be modified by a random offset. The data size of variants of a given content segment can be equalized by adding one or more portions of data to one or more of the variants.
