Empowering Digital Agriculture: A Privacy-Preserving Framework for Data Sharing and Collaborative Research

2025-06-25

AI Summary

Farmers’ privacy concerns—such as discriminatory pricing and resource manipulation—hinder agricultural data sharing, impeding data-driven agricultural advancement. Method: This paper proposes the first privacy-preserving collaborative modeling framework tailored to agriculture, integrating Principal Component Analysis (PCA) for dimensionality reduction with Laplace-mechanism differential privacy to ensure individual data irretrievability while preserving feature fidelity; it further incorporates federated learning to enable on-device personalized model training and cross-farmer collaborative modeling. Contributions/Results: Experiments on real-world agricultural datasets demonstrate robustness against adversarial attacks, near-centralized model performance (prediction error <3%), and support for farmer similarity matching and scientific collaboration. The framework provides a practical, deployable solution for secure agricultural data sharing, collaborative innovation, and evidence-based decision-making.

Abstract

Data-driven agriculture, which integrates technology and data into agricultural practices, has the potential to improve crop yield, disease resilience, and long-term soil health. However, privacy concerns, such as adverse pricing, discrimination, and resource manipulation, deter farmers from sharing data, as it can be used against them. To address this barrier, we propose a privacy-preserving framework that enables secure data sharing and collaboration for research and development while mitigating privacy risks. The framework combines dimensionality reduction techniques (like Principal Component Analysis (PCA)) and differential privacy by introducing Laplacian noise to protect sensitive information. The proposed framework allows researchers to identify potential collaborators for a target farmer and train personalized machine learning models either on the data of identified collaborators via federated learning or directly on the aggregated privacy-protected data. It also allows farmers to identify potential collaborators based on similarities. We have validated this on real-life datasets, demonstrating robust privacy protection against adversarial attacks and utility performance comparable to a centralized system. We demonstrate how this framework can facilitate collaboration among farmers and help researchers pursue broader research objectives. The adoption of the framework can empower researchers and policymakers to leverage agricultural data responsibly, paving the way for transformative advances in data-driven agriculture. By addressing critical privacy challenges, this work supports secure data integration, fostering innovation and sustainability in agricultural systems.
