ABSTRACT:
A method of identifying a valid version of a data value and voting on separate instances of the data value is described. A processor receives an instance of the data value generated by one processor and a transmitted version of that generated instance transmitted by another processor and compares the received values to validate them. The processor further determines an agreed version of the data value from a comparison of the validated instances. As a result a simple and robust voting system is provided.
