With Orin Kerr, a professor at Stanford Law School, to talk about the legal aspect of digital security.

When can the government read your email or monitor your web surfing? When can the police search your phone or copy your computer files? In the United States, the answers come from the Fourth Amendment to the Constitution and its ban on 'unreasonable searches and seizures.'

In his presentation, inspired from his book "The Digital Fourth Amendment: Privacy and Policing in Our Online World," , Orin Kerr shows how judges must craft new constitutional rules for the new world of digital evidence. Kerr provides a blueprint for legal change with clear rules for courts to adopt to restore our constitutional rights in the computer age.
