Ensuring the security and integrity of data is crucial in the current digital environment. With a focus on collaboration between data owners, users, and administrators and the integration of cutting-edge methods like encryption and invisible digital watermarking, this project offers a comprehensive solution for data management. The three primary components of the system are administrators, users, and data owners. Owners of data have the ability to upload a variety of assets, such as documents, photos, and PDFs, and add undetectable digital watermarks on them. These watermarks are used for tracking and ownership verification since they contain encrypted text. After authenticating, users get access to a personalized dashboard where they may browse the information of files that data owners have submitted. Users receive an email containing a public-private key combination after choosing a file to download. The file and its concealed watermark can be safely retrieved and viewed with this key pair. A key component in guaranteeing data security across the system is encryption. Sensitive data, such as user information, file details, and key information, is encrypted and decrypted using AES encryption and stored in the database. Administrators can monitor key distributions, file interactions, and user activity with privileged access. They are able to keep an eye on file downloads, follow user activities, and make sure security protocols are followed. The architecture of the system places a high priority on data privacy and integrity, protecting against illegal access and tampering with strong encryption techniques and undetectable digital watermarking. The project offers a strong foundation for safe data management and cooperation in digital environments by combining these cutting-edge technologies.
