Authorization Mechanism Based on Lineage

This paper proposes a new authorization mechanism for keeping the consistency of security attributes of a file and its duplicates in coping or quoting. Like life with same lineage has same characteristics in propagating, security attributes of files with same lineage will be hold consistency in the same way. Learning from the lineage principle in the nature and the function of DNA in living creatures, treating a file as a living creature, file DNA including security attributes, security attributes of files can be kept consistency by inheriting and crossing of file DNA. A rule of accessing file is constituted according to the file DNA.
