Privacy-Enhancing Technologies (PETs) are designed to protect user data from unauthorized access and ensure anonymity during the storage and transfer of files in decentralized systems. These technologies utilize cryptographic techniques, such as encryption and zero-knowledge proofs, to safeguard sensitive information while allowing users to maintain control over their data. The primary goal of PETs is to empower users with privacy rights and enhance trust in decentralized file storage solutions, making them essential in an era where data breaches and privacy concerns are prevalent.
