Tecsec
The solutions offered here enable; differential access to content, within a document (redaction) down to a period in sentence. Attribute based access is enforced by the use of multiple algorithms for compartmentation and hierarchical access to the objects via cryptography while reflecting the taxonomy of the information owner. At the same time the burden per object is a mere 500 bytes without knowing who might want to retrieve or access the information ahead of time, rather than the limitation of needing to know who, the process offers access by content descriptors; access by what. The resultant is protected data, indifferent to network topography; facilitating transmission as a matter of availability and storage a matter of convenience.
