Sexually explicit Internet chat rooms are increasingly used by pedophiles to reach potential victims. Logging and linking suspects to chat room conversations and e-mails exchanged with undercover detectives are crucial to prosecuting travelers, i.e., pedophiles who travel across state lines to engage in sexual acts with minors. This paper describes two tools, a chat room monitor and a remote fingerprinter, for acquiring and preserving evidence. The chat room monitor logs online communications as well as screen images and keystrokes of the undercover detective. stored to allow the chronological reconstruction and replay of the investigation. The remote fingerprinter uses sophisticated scanning techniques to capture and preserve a unique fingerprint of the suspect's computer over the Internet. Once the suspect's computer is seized, it is scanned again; matching this new fingerprint with the remotely acquired fingerprint establishes that the suspect's computer was used to communicate with the detective.
