Digital evidence protection model with batch-verifying and public verifiability for computer forensics

Abstract

The traditional integrity protection of evidence currently available only accounts for the entire time between seizure and presentation. Few people focus their eyes on the time before seizure. Here, through analyzing in detail the relation between digital evidence and intrusion process, a digital evidence protection model with batch-verifying and public verifiability is proposed to protect the generated digital evidence in time. The new protection model can reasonably account for the entire time between generation and presentation. The digital evidence based on the new model is valid and acceptable. © 2013 Springer-Verlag.
