Depending on the information sharing circumstance, the sharing partner may be defined at the individual, group, or organization level and information may be defined by specific content, type, or security categorization. The operating system must restrict data in some manner (e.g., privileged medical, contract-sensitive, proprietary, personally identifiable information, special access programs/compartments) and must provide the capability to automatically enable authorized users to make information sharing decisions based upon access authorizations. |
