Entering the 21st century, people step in the age of informatization and networking, the emergence and the development of internet bings a great and profound information technology revolution for the modern society. Recur to internet, the information spread all over the world at great speed, it brings huge influence for the content and the way of human society's activity, and also brings far-reaching influence for the politics, the economy, the culture and the science of society.At the same time, informational socialization brings about the new development of crime.

Just because of these new changes and developments in crime, it brings a new research project--Electronic Evidence for the theory and practice of criminal investigation. In the crime involves computer and network, traditional evidence can't come up to the requirement of proving the fact of the case clearly, and to take its place, Electronic Evidence becomes a indispensable evidence to prove the fact of the case, and for investgafion, traditional methods of collecting evidence can't be used to collect Electronic Evidence directly, so how to collect Electronic Evidence thoroughly and effectively becomes the key of investigating these cases. Therefore, it is necessary to make an overall and profound research into Electronic Evidence, so as to cope with the challenge to investigation form the development of the scientific technology.
