Trust in systems takes the form of faceless commitments, in which faith is sustained in the workings of knowledge of which the lay person is largely ignorant. … Trust in persons involves facework commitments, in which indicators of the integrity of others (within given arenas of action) are sought. … Reembedding refers to processes by means of which faceless commitments are sustained or transformed by facework.

DEFINE: Giddens distinguishes faceless commitments (trust in expert systems) from facework commitments (trust in persons), with reembedding as the process connecting them.
