Privacy Concerns with Digital Forensics

Abstract

Digital forensics is a rapidly growing technology for examining the contents of computers and digital devices. It raises many challenges to conventional notions of privacy because it involves a considerably more detailed search of digital data than is possible with other techniques, and it can be done surreptitiously. However, there are analogies to homes and the rights of individuals to be free from unwarranted searches and seizures in their private spaces. Even though commercial software and data comprises most of digital space, there are clearly enclaves of data that deserves to be kept private. We discuss the techniques of digital forensics and investigative targets. We identify key challenges to privacy, and outline both the legal protections and the technical protections available. Unfortunately, privacy laws are ineffective in most countries, and users need to take their own measures to protect themselves.
