Fuzzy Credentials

A sales representative was in a customer’s office recently with our 34K Series Standalone lock. The customer was reviewing the brochure when he noted one of the additional features was a “fuzzy credential entry available” and asked what it was.

It’s a good question and the answer may help dispell the image that just popped into your head from hearing the term fuzzy credential.

Introduced in 1965 by Lotfi Zadeh with the proposal of the “fuzzy set theory,” it is a form of “Many-valued logic in which the truth values of variables may be any real number between 0 and 1. It is employed to handle the concept of partial truth, where the truth value may range between completely true and completely false.” ¹

For our standalone 34K Series this means if the lock is in the fuzzy mode it allows a user to enter a random string of numbers that includes the user’s complete access code. This code will grant access as if the user entered just their given access code.

The next logical question is why someone would enter a string of random numbers that includes their code, versus just entering their code to access entry?  If you’re escorting a visitor through the building, you may want to use the fuzzy mode in order to conceal your personal entry code. This will save you from having to change the code to maintain security.  Or, if your entry door with the 34K Series is next to a public area, it would be safer to use the fuzzy code as it is difficult for people to remember a long string of numbers.

The next time you hear the term fuzzy credentials you’ll know what it means!
