Is our DNA the government's business? The very things that we discard everyday and never think twice about-hair, skin, and saliva-can be clues about who we are. They can also as well as liabilities. Traces focuses on the work of artist Heather Dewey-Hagborg, who created Stranger Visions, a series of masks based on DNA samples extracted from trash discarded in public places, and Invisible, a spray that erases and obfuscates DNA. Through her art, she raises questions around DNA privacy that parallel the very questions we are asking about who has access to our personal data.
