Abstract: After giving the forensic model of “man + tools + confirmation”, trusted forensic (TF) is proposed. From the trusted static attributes of digital data and trusted dynamic behavior of forensic method, the TF’s goal is to get the trusted result. According to the strict process of computer forensics, the computer forensics model is been built based on the waterfall model. Finally, the model is analyzed from five aspects, such as trusted expressing, trusted analyzing, trusted extracting, trusted fixing, and trusted discovering.
Key words: information security; trusted forensics; waterfall model; reliability; forensic model
