The director posted a close-up picture of a Starfleet badge along with two relevant hashtags, "#LLAP" which is the Vulcan salute, "Live long and prosper" and "#StarTrekBeyond" on Twitter.
The second hashtag "Star Trek Beyond" happens to be the title of the third movie in the rebooted Star Trek franchise, reported People magazine.
"Star Trek Beyond" follows a convention set by the previous film, "Star Trek Into Darkness".
Lin, best known for directing many of the "Fast and Furious" movies, takes over directorial duties from J J Abrams, who helmed the previous two "Star Trek" films and now producing the third.
