Bringing hardware-level integrity to software-based electronic monitoring. The forensic-grade alternative to traditional ankle monitors.
Minnesota SF 4760 mandates the evaluation and creation of standards for GPS monitoring devices. Until now, judicial districts faced a binary choice:
Ankle Monitors: High cost ($15/day), significant social stigma, and limited scalability.
Basic Safety Apps: Easily spoofed with "Fake GPS" software, vulnerable to OS manipulation (Root/Jailbreak), and untrusted by law enforcement.
Peabody Compliance introduces a third way: **Forensic-Grade Mobile Monitoring** that costs 90% less than physical hardware while providing 100% higher data integrity than any other app on the market.
Standard App Trust Level
Peabody Hardened Trust Level
How do we know the respondent hasn't left their phone at home?
The Solution: Biometric Binding. Peabody mandates periodic "Presence Heartbeats." The user must perform a FaceID or Fingerprint check that is cryptographically signed by the **Secure Enclave**. If the liveness check fails or isn't performed, an "Evasion Alert" is triggered instantly.
What if the user kills the app or disables location services?
The Solution: Chain of Trust Monitoring. Our SDK monitors the "Signal Health" in the background. If location permissions are revoked, the phone is put in Airplane Mode, or the app is force-closed, Peabody’s server-side logic identifies the **break in the Chain of Trust** within sub-seconds and notifies the monitoring officer.
Organized rings use specialized SDR hardware (HackRF One) to broadcast fake GPS signals.
The Solution: BSSID Triangulation. Even if a fraudster spoofs the GPS satellites, they cannot spoof the 50 nearby WiFi routers and cell towers. Peabody cross-references these signals. If the GPS says "Home" but the WiFi environment says "Excluded Zone," the breach is logged.
Constant biometric prompts are intrusive and lead to officer "alert fatigue." Peabody utilizes a **Weighted Risk Model** to maintain monitoring during sleep and periods of inactivity.
When the device is within a "Home Geofence" and has been stationary for 20+ minutes (via accelerometer data), FaceID requirements are suspended in favor of passive BSSID polling. If the environment changes without a biometric handshake, the alarm sounds.
For high-risk cases, Peabody supports pairing with a low-cost Bluetooth Low Energy (BLE) wristband. This acts as a secondary "Proof of Proximity." If the respondent leaves their phone at home while wearing the band, the phone triggers a "Separation Alert" the moment they move 30 feet away.
Peabody-compatible beacons utilize conductive fiber straps and capacitive skin sensors. If the strap is cut or the device is removed from the wrist, the internal circuit is broken, triggering an immediate "Hardware Tamper" alert via the SDK's secure tunnel.
Proof that the monitoring app is running on a genuine physical device, not an emulator or a virtualized environment designed to mask the user's actual location.
Every location ping is digitally signed by the device's hardware, preventing "Replay Attacks" where a user tries to send a previously recorded "Safe" location.
Instant enforcement of state-level boundaries and tribal land exclusion zones, satisfying the "Particularity" requirement established by the MN Supreme Court.
