Multi-Level Secure Collaborative Computing Environment

A computer-implemented method, comprising:

• receiving a biometric signature associated with a particular one of a plurality of users from a biometric reading device of a client, the client coupled to a multi-level secure computing network comprising a plurality of data repositories coupled together in a federated network, the plurality of data repositories storing information according to a ranked classification system comprising a plurality of security levels;
• initiating a login session with the client according to the received biometric signature associated with the particular user;
• and
• restricting access to the information stored in the plurality of data repositories according to one or more security levels associated with the particular user as specified by an identity token associated with the particular user.

Code implemented on a computer-readable medium and when executed by a computer, operable to perform operations comprising:

• receiving a biometric signature associated with a particular one of a plurality of users from a biometric reading device of a client, the client coupled to a multi-level secure computing network comprising a plurality of data repositories coupled together in a federated network, the plurality of data repositories storing information according to a ranked classification system comprising a plurality of security levels;
• initiating a login session with the client according to the received biometric signature associated with the particular user;
• and
• restricting access to the information stored in the plurality of data repositories according to one or more security levels associated with the particular user as specified by an identity token associated with the particular user.
