An honor system, trust system or honesty system is a way of running a variety of endeavors based on trust, honor, and honesty.
The honor system is also a system granting freedom from customary surveillance (as to students or prisoners) with the understanding that those who are so freed will be bound by their honor to observe regulations (e.g. prison farms may be operated under the honor system),[1] and will therefore not abuse the trust placed in them.
