The term "software independence" (SI) was coined by Dr. Ron Rivest and NIST researcher John Wack. A software independent voting machine is one whose tabulation record does not rely solely on software. The goal of an SI system is to definitively determine whether all votes were recorded legitimately or in error.[1]
The technical definition of SI is: [2]
A voting system is software-independent if an undetected change or error in its software cannot cause an undetectable change or error in an election outcome.
SI has been redefined as a global property for a tabulation of votes rather than of each individual vote, aiming to detect rather than prevent error and fraud through human processes.[3]
