Centralized Data Management and SaaS with End-to-End Encryption

摘要

New techniques for securely managing cloud-based data, documents and software-as-a-service (“SaaS”) are provided. In some embodiments, End-to-End encryption is carried out for aspects of a group project managed via a system including a remote server hub delivering SaaS. Structured data and project content are all managed securely by the server hub and end users. In some embodiments, the end users share new types of encryption keys (and bundles thereof) to securely decrypt data, while the server manages the data, yet remains blind to data contents due to encryption. In some embodiments, the server hub, even though blind to data contents due to encryption, is still able to manage data differently based on its content, via unique new encrypted data management tools. For example, in some aspects of the invention, new data, and alterations to the structured data and project content, are managed by tools referred to as “change objects.”
