56 F. Supp. 3d 584
S.D.N.Y.2014Background
- Defendant Frank DiTomasso charged with production/transportation of child pornography; key evidence derived from ISP monitoring of his AOL emails and Omegle chats that produced NCMEC reports.
- AOL scanned incoming emails with two hashing systems: PhotoDNA (similarity check with human review) and IDFP (exact-hash match; automated quarantine and NCMEC report). Two AOL-generated NCMEC reports resulted.
- Omegle used automated snapshotting and automated filtering of chats, with human review on flags; three Omegle-originated NCMEC reports resulted from flagged snapshots.
- AOL and Omegle each had terms/policies disclosing monitoring and potential disclosure to law enforcement; AOL’s policy explicitly reserved cooperation with law enforcement, Omegle’s emphasized IP logging for law enforcement and chat monitoring for quality control.
- DiTomasso was on probation with a consent-to-search condition allowing probation officers (or designees) to inspect his computer; he moved to suppress evidence as Fourth Amendment violations, arguing ISPs acted as government agents and he had a reasonable expectation of privacy.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether DiTomasso had a reasonable expectation of privacy in contents of emails and Omegle chats | DiTomasso: yes — one-on-one communications are private; ISP warning does not eliminate expectation | Government: no — disclosure to third parties and ISP notices negate expectations | Court: Yes — reasonable expectation of privacy exists for both email content and Omegle chats |
| Standing to challenge interception of incoming emails quarantined before delivery | DiTomasso: recipient of intended emails has standing to challenge search | Government: no standing because emails never reached him | Court: DiTomasso has standing; recipient interest in incoming correspondence is protected |
| Whether DiTomasso’s probation search condition eliminated Fourth Amendment protection | Government: probation consent severely diminishes or eliminates expectation of privacy in computer communications | DiTomasso: probation consent was limited to probation supervision and does not strip all Fourth Amendment rights | Court: Probation agreement did not extinguish expectation of privacy as to law enforcement searches generally |
| Whether assent to ISP terms constituted consent to searches by law enforcement (AOL vs Omegle) | DiTomasso: did not consent to ISP acting as law enforcement agents | Government: terms of service consented to monitoring and disclosure to law enforcement | Court: Differentiated — AOL’s explicit cooperation language constituted objective consent to law-enforcement search of emails (consent valid); Omegle’s policy did not show consent to act as law-enforcement agent for chat monitoring (issue reserved; suppression hearing ordered) |
