Security in peer to peer synchronization applications

摘要

A computing system is configured as a manager in a secure peer-to-peer data synchronization community. The system comprises a processor; and memory storing the following components: a tracking component of a data storage system, a sync component for creating sync relationships between folders on the computing system and folders stored on other computing systems in the synchronization community a sync application that receives user input to the computing system for communicating with the sync component. The tracking component tracks changes that occur to the data storage system. The sync component includes a user sync manager component for creating the sync relationships, creating synchronized folders, inviting users to join the synchronization community, accepting invitations to join the synchronization community, removing users from the synchronization community, and maintaining a membership list of each user's access rights to synchronized folders in the synchronization community. Upon receiving user input specifying that a first folder of the computing system is to be synchronized within the synchronization community, the sync application communicates the user input to the user sync manager of the sync component, such that the user sync manager creates an invitation which includes an indication that the first folder is to be synchronized with another folder on a second computing system in the synchronization community and also includes the membership list that specifies the access rights the user of the second computing system as well as at least one other user of another computing system in the synchronization community will have to the first folder. The user sync manager further sending the invitation to the second computing system such that in response to the user of the second computing system selecting a second folder with which to synchronize the first folder, a sync relationship is created between the first and second 15 folders such that the second folder stores the membership list including the access rights for the user of the second computing system as well as the access rights of the at least one other user for accessing the first folder.
