Digital evidence in criminal law

the long version

"This title addresses the legal issues relating to digital evidence collected during the course of a criminal investigation and its subsequent use at trial. It surveys key technologies (cookies, web-cases, recovery methods) and explains them in a simple, easy to understand fashion. The book includes a discussion on types of evidence where they can be found, who the required witnesses are and the challenges of obtaining and preserving digital evidence in the first place. Special emphasis is placed upon digital evidence generated by the police and seized from suspects. It further covers the effect on the law of evidence that has resulted from the internet communications revolution."--Pub. desc.
