Fraud Intelligence Infrastructure

Prevent Repeat Seller Scams Before They Resurface.

SafeKeep is a cross-platform fraud intelligence network that detects linked seller identities across electronics resale marketplaces — without sharing raw data.

Most resale platforms ban scam sellers, but those sellers often re-register under new details or move to another marketplace. SafeKeep detects identity recurrence at signup and listing time.

The Problem

Bans Don't Stop Repeat Sellers.

Fraud is rarely isolated. Identity reuse across platforms is common in electronics resale. Without cross-platform intelligence, recurrence often goes undetected.

  • Deposit scams via WhatsApp
  • Fake device listings
  • Re-registration after bans
  • Identity recycling across marketplaces

The Solution

Detect Identity Recurrence at Signup and Listing Time.

SafeKeep normalizes and deterministically hashes seller contact signals such as phone, email, and name. Identity clusters are matched across member platforms, and structured risk signals are returned.

No raw data exchange. No competitor exposure.

How It Works

01

Platform sends seller data via API

02

Signals are normalized and hashed

03

Identity clusters are matched

04

Structured risk signal is returned

Platforms retain full moderation control.

Built with Privacy and Integrity by Design.

No raw seller data shared between platforms

Deterministic hashing before storage

Weighted signals (no single report blacklists)

Structured fraud submission only

Rectification framework for disputed signals

Platforms make final moderation decisions
