David R. Wallace is an American
mathematician
and inventor. He is known for the Wallace algorithm as well as “Software Cloaking”, a patented method for hiding the internal operations of computer programs.
from Columbia University
(BA), University of California at Berkeley (MA) and a Ph.D in 1975 at Tulane University
with his dissertation Permutation Groupoids and Circuit Bases: An Algebraic Resolution of Some Graph Structures.
He has been a professor at Emory
, DePauw and Boston University
. He was Chief Software Architect for Alliant, Chief compiler architect at Sun Microsystems
, and co-founder of Determina (now part of VMware
).

He is also the inventor of “Software Cloaking”, a technology for preventing reverse engineering
. This process is primarily used to prevent hackers
from cracking DRM
systems. Cloaking hides the internal operation of a program using mathematical transformations. His patent for this technology, “System and Method for Cloaking Software,” was granted by the USPTO in February, 2001.
David R. Wallace has several patents pending for a new form of software security called 'Greencastle Vulnerability Shield'.

Education and professional career
Wallace received degrees in mathematicsMathematics
Mathematics is the study of quantity, space, structure, and change. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity...
