Abstract: A secure data collaboration communication system and apparatus provides secure communication of data to multiple users of client systems to enable data collaboration. The secure data collaboration communication system and apparatus generate, share, receive, and utilize widget references to generate a common dataset. To accommodate varying levels of data access to a common dataset, in at least one embodiment, each user of the secure data collaboration communication system is associated with an access policy defining the level of data access for the user. The secure data collaboration communication system and apparatus apply the access policy to the dataset generated using the widget reference to limit exposure to data in the dataset commensurate with the user's data access level. Thus, a secure data collaboration communication system and apparatus provides a technical solution to the technical problem of providing secure collaborative data access to users having diverse levels of data access authorization.
