In Russian we have a phrase "honest people's lock" (замок от честных людей), which means a security measure which can be easily bypassed by a resolute and skillful perpetrator but still serves as a protection from an amateur or random person willing to take a chance.
Examples of such a security measure would be:
- Three-digit rotary lock on your suitcase or bicycle chain lock
- Anti-theft lug nuts of your car's wheel
- Disabling copy-paste or a right click on a website as an anti-copyright infringement measure
Is there such a phrase or word in English?
I'm using a combination bike chain lock. Of course it's only a ____, but you don't have to carry you key around with you and it still keeps kids from stealing your bike.
