Embedding advertiser MirriAd has digitally added special keyword clues to live-action clips of the movie that are currently running on .
The clues have been placed in three clips from the film using MirriAd's ZoneSense technology, which renders and blends content into the video, making the addition invisible to the viewer.
The competition follows the espionage theme of the movie, which stars Matt Damon and Julia Stiles, and entrants can win prizes associated with the film.
This is the first time the embedding technique has been used in the UK. MirriAd is able to embed content into video streams on any platform and scale without affecting quality of the original footage. The technology offers brands a new way of exposing themselves wherever audiences are watching video in large numbers.
Mark Popkiewicz, chief executive of MirriAd, said: "This is a fantastic showcase for our embedded advertising technology. Content owners are looking for ever-diverse ways of using technology to deliver added revenue streams and innovative marketing solutions.
"In the coming months, we'll be rolling out some very exciting work that will demonstrate the power and value of graphically contextual in-video advertising to brands, content owners and media buyers."
'The Bourne Ultimatum' competition was conceived in partnership with WPP Group's media planning agency and MediaCom.
