Method and system for handling of group sharing in a distributed data storage, particularly in P2P environment
Patent issued Feb 7, 2017. Patent US 9563783 https://www.google.com/patents/US9563783
This patent is the key management technology used in Tresorit. It presents a solution for having and sharing independent folders without compromising end-to-end encryption. The invention relates to a method and system for handling of group sharing in a distributed data storage, particularly P2P environment, where online unexploited storage capacity and bandwidth of users of a community connected to a network or the Internet are utilized. Files of a user are cut into pieces which are then distributed among other online users.
Client-side encryption with DRM
Patent issued Sep 8, 2015. Patent number US 9129095 https://www.google.com/patents/US9129095
A technique for extending security to a data object (e.g., a document, a file, a message, etc.) once it has been shared and during collaboration with others who have access rights to that data object. The approach combines group key-based client-side encryption to secure the data object as it travels from a user's computer, to the cloud, and to a chosen collaborator's computer, together with a digital rights management (DRM) layer.
