1 Problem Statement
A protective order is only as effective as the victim's ability to report violations — and for domestic violence victims, reporting is dangerous.
When an abuser violates a restraining order — showing up at the victim's workplace, sending threatening messages, following the victim — the victim must:
- Recognize the violation and decide to report it
- Collect evidence (screenshot, photo, recording)
- Contact the police — often by calling a non-emergency line, waiting on hold, or visiting a precinct
- Transmit the evidence — typically by printing screenshots, emailing files to a detective, or physically handing over a phone
Each of these steps introduces delay, risk, and friction:
Delay is dangerous. A protective order violation is often a precursor to escalated violence. The Department of Justice reports that 60% of domestic violence homicides involve prior protective order violations. Every hour between a violation and police awareness increases victim risk.
Evidence is lost. Victims photograph threatening messages on their phone, but the images are often blurry, missing timestamps, or lacking context that prosecutors need. By the time the evidence reaches a detective, it may have been altered, forwarded, or deleted.
The phone is a weapon. If the abuser gets access to the victim's phone and discovers evidence collection activity — photos of their car at the victim's workplace, screenshots of threatening messages, a police department app — the victim faces immediate retaliation.
Communication is fragmented. The victim may have a different detective assigned than the one they last spoke to. There is no single, secure, persistent communication channel between the victim and their assigned detective.
The result is a reporting gap: victims know violations are occurring but lack a safe, fast, and evidence-preserving way to report them to police.
2 Proposed Solution
Safe-Link is a highly secure mobile application issued directly by police to domestic violence victims, providing a discreet, one-tap channel to capture evidence of restraining order violations and submit it directly into the assigned detective's case file — with immediate notification and tamper-proof integrity.
How It Works
1. Police-Issued Setup: When a detective is assigned to a DV case with a protective order, they provision the Safe-Link app on the victim's phone. The app is configured with the detective's contact information, case reference, and protective order number.
2. Disguised Interface: The app presents as a neutral utility (weather/notes app) on the victim's home screen. A hidden gesture activates the real interface. If the abuser opens the app, they see only a benign utility — not a police evidence tool.
3. One-Tap Evidence Capture: Photo, video, text description, and GPS coordinates — all captured with a single tap when the victim witnesses a violation.
4. Tamper-Proof Submission: Each piece of evidence is SHA-256 hashed at the point of capture, creating cryptographic proof that the evidence has not been altered. Encrypted and transmitted directly to the detective's case file.
5. Immediate Detective Alert: The detective receives an instant push notification when new evidence is submitted, with case reference for immediate triage. The victim is notified of progress.
6. Evidence Safety: After submission, the app can automatically delete the captured photo or video from the device's photo gallery — preventing the abuser from discovering evidence collection activity.

3 Innovation & Significance
🔒 Disguised Security Interface
Safe-Link is the first law enforcement evidence tool designed with victim physical safety as a primary requirement. The disguised screen protects victims from retaliation when abusers access their phones.
🔗 Direct Police Channel
Unlike general tip lines, 911 calls, or email, Safe-Link creates a persistent, encrypted, one-to-one channel between the victim and their specific assigned detective.
✅ Evidence Integrity from Capture
SHA-256 hashing at capture, combined with encrypted transmission and automatic chain of custody logging, creates evidence that prosecutors can present with confidence.
🗑️ Automatic Gallery Cleanup
The evidence self-destruct feature addresses the specific scenario where an abuser searches the victim's phone for signs of reporting activity — a unique safety feature no existing tool provides.
4 MVP Feature Set
5 Target Users & Deployment
Primary Users
DV victims with active protective orders, assigned DV detectives
Secondary Users
Victim advocates, prosecutors, supervising officers
Deployment Model
Police-provisioned installation on victim devices. When a victim obtains a protective order, the assigned detective installs Safe-Link on the victim's phone during an in-person meeting.
