To address participant privacy in market research, clear informed consent is essential. Transparency about data collection, its purpose, and participant rights builds trust. Use data anonymization to protect identities by removing personal details and focusing on aggregated trends. Follow regulations like GDPR and CCPA, ensuring compliance with data access requests and breach notifications. Limit data collection to only what’s necessary and secure it using encryption and controlled access. Choose trusted, secure platforms for data storage, and delete data once it’s no longer required. Prioritize privacy, building participant trust through transparency and ethical data handling practices.
