Melik Ohanian's video installation, Hidden consists of two images: one visible, and a hidden second invisible image encoded within the picture. The second image has been encrypted into the work using a process called steganography — a method used to encode hidden information inside an image. According to the FBI, the plotters of the 9/11 attacks used this system to transmit information via the Internet. In Ohanian's work, the second image cannot be revealed without the use of decoding software, and therefore can only be imagined by the viewer. Hidden resonates with notions of territory, and the politics of control, defense, and attack.

Ohanian has received international acclaim for works in a broad range of media that address issues of personal autonomy and identity, access to territory and information, as well as conceptions of time in today's global culture.
