This document appears to contradict itself. Page 4 boasts of "static" data being secure but the LDS2 proposal promises "update" of photo as well as intrusion of travel patterns and other data that presumably would be used to restrict/override a passenger's use of a visa.
Also, notice how page 6 says "Less reliance on physical document inspection procedures" as if a machine isn't physical. What they mean is less reliance on HUMAN inspectors.
