In an era of increasingly interconnected digital landscapes, where data breaches and privacy concerns loom large, our research focuses on deploying robust user-side encryption within cloud environments. By integrating this encryption technology seamlessly into existing cloud infrastructure, we aim to provide individuals and organizations with a powerful tool to safeguard their sensitive information. Our innovative approach not only fortifies data security but also promotes seamless and secure collaboration among users, ensuring that confidential data remains confidential, even when shared in the cloud. With CloudLock, we aspire to usher in a new era of trust and confidence in cloud-based data sharing.Leveraging cutting-edge cryptographic techniques and an innovative encryption algorithm designed specifically for user-side encryption, CloudLock places data protection firmly in the hands of the users. Unlike traditional server-side encryption, our approach ensures that data is encrypted on the user's device before it even reaches the cloud server, rendering it impervious to unauthorized access. This groundbreaking methodology not only enhances data security but also grants users full control over their shared data, mitigating the risk of data breaches and unauthorized access. CloudLock is poised to revolutionize the way individuals and organizations collaborate in the cloud, setting a new standard for secure data sharing in an increasingly interconnected digital world.
