# Fraud Detector Dataset
Synthetic multi-modal dataset created for the **Reply / ReplyMirror Fraud Detection Challenge**. It simulates real-world banking activity across five data types — transactions, users, locations, communications, and audio calls — designed to support fraud detection research combining tabular, textual, geospatial, and audio signals.
The companion system that consumes this data is available at [Honi05/Fraud-Detector](https://github.com/Honi05/Fraud-Detector).

## File Descriptions
### ransactions.csv
The core file. Contains individual financial transactions with fields for transaction ID, amount, timestamp, merchant, and other contextual attributes. This is the primary target file — fraud predictions are made at the transaction level.
### users.json
User profile records. Includes demographic and account information for each customer. Used to build behavioral baselines and detect deviations from a user's normal activity patterns.
### locations.json
Geolocation records linked to transactions or user activity. Used to flag geographical inconsistencies such as impossible travel sequences or transactions in unusual regions.
### sms.json
SMS message logs associated with users. Analyzed for phishing indicators, suspicious links, and fraud-related language patterns using LLM-based text scoring.
### mails.json
Email logs per user. Similar to SMS — processed for social engineering cues, fraud language, and anomalous communication behavior.
### udio/ (48 MP3 files)
Recorded phone call segments named by timestamp and participant (e.g., 20870117_010505-jolanda_orsini.mp3). Intended for voice-based fraud signal extraction.

## Usage
This dataset is used as input to a multi-agent fraud detection pipeline:
`ash
python main.py --data ./data --output ./output/predictions.txt
`
The pipeline ingests all five modalities and produces a ranked list of flagged transaction IDs.
