Abstract: A user authentication system and method includes a network of guardian nodes and gatekeeper nodes configured to securely communicate with one another. The gatekeeper nodes are connected to service providers and the guardian nodes are associated with UAS customers. The guardian nodes and gatekeeper nodes are configured to generate tokens that are passed between the guardian nodes, gatekeeper nodes, service providers and UAS customers to authenticate UAS customers requesting access to service providers.

Abstract: Systems and methods for automated retrieval, monitoring, and storage of online digital content, wherein such content includes source code and files for hosting websites, audio files, video files, data files, system files, image files, or any other content that is typically stored in third party servers. A content retrieval system hosted on a physical server or a cloud continuously monitors user data hosted on a third party server for changes to the data. The method involves creation of an index list that is updated periodically to keep track of changes to the metadata associated with the user's content. Such an approach saves time and valuable resources to individuals and/or organizations enabling them to perform periodic monitoring of their data, and enabling rollback to a previous version of their data whenever needed. The system additionally monitors user content for malicious attacks and hacks, and provides notification alerts relating to the same.
