Title of Project: Privacy-respecting digital forensics

 

Criminal activity is rampant on the Internet.  Traditionally, investigators and law enforcement officers have had to rely on mostly ad hoc digital forensic trails to catch the perpetrators of these crimes.  These traditional forensic trails, while helpful, are generally limited in that:  (1) they are weak and forgeable and (2) they do not respect the privacy of normal Internet citizens in the common cases when there are no criminal incidents to investigate.

 

These limitations beg the question:  Can we create computer systems that inherently provide strongly un-forgeable yet privacy-respecting forensics evidence?  I will touch on two research directions focused on meeting these goals.  The first direction is to create a new Internet with built-in forensic trails that are both significantly stronger and more privacy-respecting than the forensic trails we have today.  The second targets creating strong, privacy-respecting methods for recovering stolen laptops and other mobile devices.
