First, stop the hating on AOL. Some of us appreciate its retro feel, not to mention the fact that for many years, it was the only game in town. Sure, today it’s frowned upon, a dinosaur, but for those of us who were early adopter, having an original AOL email address (the ones without numbers after the name) was pretty darned cool once.
Frank DiTomasso, however, might have preferred CompuServe. His choice of AOL didn’t work out all that well. Nailed for sending child porn via his AOL account, he learned that AOL monitors email attachments for illicit materials. From United States v. DiTomasso:
DiTomasso has an AOL email account — [email protected]. When AOL users send or receive emails that contain attachments, AOL runs two background monitoring systems designed to scan for illicit material, including, but not limited to, child pornography. The programs work by assigning “hash numbers” to image and video files. In essence, hash numbers are unique number-strings that can be used to archive packets of data —“fingerprint[s]” for electronic media.
AOL employs two different hashing programs. The first—the Image Detection and Filtering Process (“IDFP”)—sweeps for one-to-one matches with known child pornography. If an attached file is a one-to-one match, the email is quarantined —i.e., diverted from the recipient’s inbox—and an automatic report is generated and sent to the National Center for Missing and Exploited Children (“NCMEC report”).
