1. A method comprising:
receiving, from a computing device, a request to access content, wherein the request comprises a transformed version of a link, to the content, generated by the computing device based on an application of a time-based transformation of the link from a baseline time;
based on the baseline time and a time that has elapsed from the baseline time, determining that the transformed version of the link is valid; and
based on determining that the transformed version of the link is valid, causing sending, to the computing device, of a segment of the content associated with the time that has elapsed from the baseline time.
