SecureSwipe Fraud Detection Project

Overview

This project aims to detect fraudulent transactions in the SecureSwipe dataset. The dataset contains both fraudulent and successful transactions, and the goal is to build a model that can accurately classify transactions as fraudulent or successful.

Requirements

Project Structure

  • data/: Contains the dataset used for training and testing.
  • src/: Contains the source code for data preprocessing, model training, and evaluation.
  • models/: Contains saved trained models.
  • results/: Contains evaluation results and visualizations.

Steps

1. Data Preprocessing

  • Removed null, missing, and duplicate values.
  • Scaled 'amt' and 'time' columns using RobustScaler to handle outliers.
  • Detected and handled outliers using the Interquartile Range (IQR) method.
  • Oversampled the data using Synthetic Minority Over-sampling Technique (SMOTE) due to class imbalance.

2. Model Training

  • Utilized Logistic Regression as the classification model.
  • Checked for multicollinearity using Variance Inflation Factor (VIF).
  • Addressed multicollinearity by applying Ridge regularization.

3. Evaluation Metrics

  • Evaluated the model using the following metrics:
    • Accuracy
    • Precision
    • Recall
    • Confusion Matrix

4. Privacy-Preserving Techniques

  • Implemented Privacy-Preserving Aggregated Training with Exponential Mechanism (PATE) using Laplacian noise for security.

Usage

  1. Clone the repository:
git clone https://github.com/your-username/SecureSwipe-Fraud-Detection.git

Navigate to the project directory:

cd SecureSwipe-Fraud-Detection

Install dependencies:

pip install -r requirements.txt
