When challenging the admissibility of the digital evidence the defense examiner will evaluate the authentication and chain of custody techniques used. The accused made a blog on the Internet site threatening a false bomb attack. He is on camera seated at the computer, and the video is being examined by investigation experts after someone gave a tip that she saw some of the message on accident. There are also log-ins used at the Library. Identify in a whitepaper the possible authentication and chain of custody techniques used to ensure an acceptable forensics investigative process.

The librarian walked up on the e-mail account while the suspect was away and found incriminating information in an open e-mail, which was reported to law enforcement.
