Artificial Intelligence Now Capable Of Bypassing Fingerprint Security

Artificial Intelligence has grown in recent years to such a point that according to a team of 5 NYU researchers, fingerprint identification, found in many products today, including but not limited to deadbolt locks, entrance sets, electric strike user interfaces, access control and time clocks, among other modern day electronic products, is now able to contravene the once thought of high security alternative to mechanical key entry systems.

We have previously touted the benefits of biometric fingerprint security scanners that were/are included in a great many differing products, including a (now discontinued) high security deadbolt lock that we sold many years ago. We realized the error of our ways, when a number of older clients were finding tremendous difficulty in registering and using the fingerprint deadbolt locks we once recommended. Specifically we found that if you were over 55 years of age, your fingerprints wear more quickly as you age. This proved to be an impediment to future sales of fingerprint operated biometric products because many elder users would have been the primary beneficiaries of keyless, fingerprint operated lock systems.

It is obvious that Apple, recognized the limitations of fingerprint identification systems when they decided to discontinue fingerprint readers in many of their largest selling product lines, like the iPhone, the iPad and other products. Many competing product manufacturers also included fingerprint readers in a host of other products, hoping to also cash in on the once burgeoning sector of the electronics products markets.

An excerpt from the article quoted in the source below explains....

"Named ‘DeepMasterPrints’, the set of fake fingerprints was generated by the NYU scientists using a neural network to be some sort of ‘master key’ for biometric authentication systems that have an error rate of one in a thousand. To work this well, DeepMasterPrints takes advantage of two properties fingerprint authentication systems have: that they scan only a part of the finger at any given time and not the whole finger; and that some features of fingerprints are more common than others. 
So, the weakness in the system here, explains The Guardian, is that fingerprint scanners never blend all the partial images to match a full fingerprint against a full record. Instead, they just compare a partial scan against partial records. This means that attackers need only match one of tens or even hundreds of recorded fingerprints in order to gain access into a secured system.
The scientists’ presented their research paper at a biometrics conference in Los Angeles in October. “The underlying method is likely to have broad applications in fingerprint security as well as fingerprint synthesis,” said NYU’s Philip Bontrager, the lead author of the paper in a statement to Gizmodo. “A similar setup to ours could be used for nefarious purposes, but it would likely not have the success rate we reported unless they optimized it for a smartphone system."

Naturally, as a security services and products provider, we try to remain updated on issues affecting security products and services to enable us to provide our growing lists of customers with updated information regarding products and services aimed at minimizing issues and mitigating security loopholes.
Apple, introduced facial recognition in many of their products, which seems to be becoming quite widely accepted across the wider marketplace.
We highly recommend consulting your local trained and qualified locksmith technician, who can advise you on great quality secure products that will provide continued secure access to your properties and security systems.

Has New York City Fixed It's Key Problems?

A post we made in October 2012 continues to find traction and views as it is still of important knowledge to us all today, as much if not more since first written in 2012.

We just updated some of the links to working links (over time websites need to keep up with their broken links to avoid the pitfalls of search engine pagerank issues) so you can view the videos and some of the links we include.

Continuing to provide links to the source of our content (even though we write our own content) credits the source and avoids us being called plagiarists.

The following story is worth remembering and continue to be an important piece of knowledge, not just for the industry but also the marketplace...

The Society Of Professional Locksmiths

is an organization of professional locksmith owners and tradespersons whose intentions are to bring respect and admiration with ethical and moral business practises back to an industry that has seen the erosion of confidence in locksmiths, wane over the past few years, thanks to improprieties and shortcoming of other supposed industry organizations.

The SOPL is fast becoming the industry's leading respected voice, training facility and source of products and services, that the market and industry have long been seeking.

Unlike other locksmith industry organizations and training offerings, the SOPL developed their own superb in-house training guide and mentoring system that is second to none in the North American market.

FDNY Keys Sold on EBAY - The NY Post - Where there's Smoke, there's Fire

On October 1st, 2012 a news story ran in the NY Post about a retired locksmith named Daniel Ferraris from New Jersey who sold a set of 5 keys on Ebay that were being called Masterkeys for the New York City Fire Department.

Source - http://www.nypost.com/p/news/local/lock_away_these_nyc_keys_g3PWCp3FzMapURRjyssJ4J

This apparently angered NY City officials and public advocate Bill DeBlasio who raised concerns over terrorism. Keywords such as being alarmed, angered, lives at risk, safety, and more surfaced. Calls to Home Land Security were even made!

DeBlasio himself went so far to say -  "We cannot let anyone sell the safety of over 8 million people so easily. Having these keys on the open market literally puts lives at risk. The billions we've spent on counter-terrorism have been severely undercut by this breech [sic]."

A NYFD lieutenant said, “This guy should be prosecuted for selling something like that."

Do You Understand What Makes A Safe ..... Safe?

In November 2008, we posted an article (below) about safes and why/how they are constructed and regulations as determined by the most populous state in the USA.

The details are still important knowledge for locksmiths, safe workers, even the general consumer....


Choosing a safe is often difficult. I have been asked many times over the years to make a recommendation to customers wishing to purchase a safe.

Before making a recommendation, I feel it necessary to ask some specific questions to a customer to help in determining a suitable product to recommend.

Many people do not understand the ratings systems for safes, probably because there is no written industry standard.

In the early 1990's, I worked for one of Australia's oldest manufacturers of quality safes, Kelly Safe Co PTY LTD. (they closed down in 1995, I believe). Kelly safes were considered a staple of the Australian landscape for about 100 years previously. They manufactured impressive quality safes for many of Australia's institutions, banks, high-society clubs, hotels etc.

The increasing competition from foreign products combined with the significant increase in raw materials cost, saw Kelly become less competitive in later years.

I learned much from my short time with them about how to grade safes.

There are many classifications of safes that are determined by each individual country/locallity as suitable for local conditions. The leading tester in the world (most respected) is known as the Underwriters Laboratory.

The questions I like to ask my clients are:

1. What approximate cash value of personal documents, jewellery, bank notes etc are you looking to secure?

This determines what grade of safe would be suitable for the contents.

2. Approximately how big (dimensions) would the individual pieces of content be for storage?

This determines the necessary internal dimensions of the recommended safe.

3. Are you looking for Burglary Protection, Fire Protection or both?

4. Would you prefer a bolt down facility, free-standing, on castors, wall-mount, floor mount, vault etc?

5. How much are you looking to spend?

The most important question is question #1, because this separates the designations of safes from each other and directly guides a professional to make the most suitable recommendation.

In California, the CDOJ (California Department Of Justice) uses the following terms:

California Department of Justice Burglary Rating (CDOJ)
Regulatory Gun Safe StandardsDOJ regulatory standards require a gun safe to meet either: 
All of the following requirements:

  1. Shall be able to fully contain firearms and provide for their secure storage.
  2. Shall have a locking system consisting of at minimum a mechanical or electronic combination lock. The mechanical or electronic combination lock utilized by the safe shall have at least 10,000 possible combinations consisting of a minimum three numbers, letters, or symbols. The lock shall be protected by a case-hardened (Rc 60+) drill-resistant steel plate, or drill-resistant material of equivalent strength.
  3. Boltwork shall consist of a minimum of three steel locking bolts of at least ½ inch thickness that intrude from the door of the safe into the body of the safe or from the body of the safe into the door of the safe, which are operated by a separate handle and secured by the lock.
  4. Shall be capable of repeated use. The exterior walls shall be constructed of a minimum 12-gauge thick steel for a single-walled safe, or the sum of the steel walls shall add up to at least .100 inches for safes with two walls. Doors shall be constructed of a minimum of two layers of 12-gauge steel, or one layer of 7-gauge steel compound construction.
  5. Door hinges shall be protected to prevent the removal of the door. Protective features include, but are not limited to: hinges not exposed to the outside, interlocking door designs, dead bars, jeweler’s lugs and active or inactive locking bolts.

or All of the following requirements:
  1. Is listed as an Underwriters Laboratories Residential Security Container;
  2. Is able to fully contain firearms;
  3. Provides for the secure storage of firearms.
Burglar safes are usually made of solid steel plate or a combination of solid steel and composite fill material such as concrete. These safes are divided into categories based on the level of protection delivered and the testing endured. Here we will discuss only seven classes: B-Rate, U.L. RSC Rating, B/C Rate, C-Rate, U.L. TL-15, U.L. TL-30 and TL-30 X6.
B-Rate is a catchall rating for essentially any box with a lock on it. The safe industry had an unwritten standard of ¼ inch body, ½ inch door. As steel prices (and shipping costs) increased manufacturers tried many things to reduce their costs. No tests are given to provide this rating. When buying a B-rate safe, look at things such as lock work, hard plates, and relocks.
U.L. Residential Security Container rating (RSC) - This UL rating is based on testing conducted for a net working time of five minutes, on all sides, with a range of tools. See U.L. TL-15 and TL-30 descriptions below for "net working time" description.
B/C-Rate Safes
This is a catchall rating for safes with at least a 1/4" steel body, 1/2 inch door PLUS additional 10 or 12 guage metal layers where composite fire resistant material is also deployed. No tests are given to provide this rating. Look at the lock work, relocks and other features when making your decision.
C-Rate Safes
This is defined as a ½ inch thick steel box with a 1-inch thick door and a lock. As before, NO tests are given to provide this rating. Look at the lock work, relocks and other features when making your decision.

The Underwriters Laboratory information:

Underwriters Laboratories Inc. (UL) Ratings
Safes given a U.L. TL-15 rating have all passed standardized tests defined in UL Standard 687 using the same tools and usually the same group of testing engineers.Construction Requirements
  • U.L. listed Group II, 1 or 1R combination lock.
  • 750 lbs. minimum or comes with instructions for anchoring in a larger safe, concrete blocks or on the premises where used.
  • Body walls of material equivalent to at least 1" open hearth steel with a minimum tensile strength of 50,000 P.S.I.
  • Walls fastened in a manner equivalent to continuous 1/4" penetration weld of open hearth steel with minimum tensile
    strength of 50,000 P.S.I.
  • One hole 1/4" or less, to accommodate electrical conductors arranged to have no direct view of the door or locking mechanism.
The label means that the safe successfully resisted entry (i.e. opening the door or making a 6" square opening entirely through the door or front face) for a NET working time of 15 minutes using "…common hand tools, drills, punches hammers, and pressure applying devices." Net working time means simply "when the tool comes off the safe the clock stops". There are over fifty different types of attacks that can be used to gain entrance into the safe. Usually they will try only 2 or 3 based on what they know about the product, and they know a lot.
Construction requirements are identical to the TL-15 above. Tests are essentially the same as the TL-15 tests except for the net working time. Testors are allowed 30 minutes and a few more tools (abrasive cutting wheels and power saws) to help them gain entrance. The label signifies the testors were unable to open the door or make a 6" square opening entirely through the door or front face within 30 minutes. Keep in mind these engineers have the manufacturing blue prints and can disassemble the safe being tested before the test begins to see how it works. They know their stuff. TL-30 x 6 - The TL-30 (30-minute) test is conducted on all six (6) sides of the safe.
Other Considerations
When you begin the search for a safe it is a good idea to speak to your insurance agent and see if a particular type of safe will reduce your insurance costs. Many times you can justify the additional expense of a higher security safe because of the premium reduction. Remember no safe is burglar proof, you are buying time. The longer it takes to break in the greater the chance to be caught, and thieves don’t like to get caught.
10 Things You Didn't Know About UL's Safe Testing
  1. The best safecrackers in the business never steal a penny. They work for UL.
  2. UL has been testing and certifying safes for more than 80 years. The first safe tested for burglary resistance was in 1923 and the first bank vault in 1925.
  3. Chisels, wenches, screwdrivers, power saws, cutting torches, crowbars, abrasive cutting wheels, jackhammers, even specified amounts of nitroglycerin are just a few of the "tools" UL technicians use during a safe attack. The idea is to test safes to worst-case scenarios. They use tools that could be found at any construction site or hardware store. They also analyze blueprints as if the burglar might have blueprints of the design and attack its weakest points to evaluate the safe for certification.
  4. UL's safe attack tests are conducted by a two-person crew. The object is to create an opening large enough to withdraw "valuables" (anywhere from 2- to 6-square-inches on a safe and up to 96-square-inches on a vault), activate the locking mechanism so the door opens or to cut as many bolts from the door as necessary to pry it open before the time specified in the rating requirement expires.
  5. Safes are rated for their resistance to attack against specific tools for a set period of time. There are a dozen different ratings, everything from ATM machines, to gun safes to bank vaults. For example, a safe that bears a Class TRTL-15X6 rating, which might be found in a jewelry store, should resist a hand tool and torch attack for a minimum of 15 minutes. A TRTL-30X6-rated safe, which would protect important documents or store money, should withstand an attack for 30 minutes. The ultimate safe rating-a TXTL60-should withstand an hour's worth of attack that includes the use of 8 ounces of nitroglycerin.
  6. Because of the size and weight of certain safes and vault doors, it is not always practical to have the product shipped to UL's laboratory locations. UL's burglary protection staff has traveled to destinations such as Japan, France, Israel, England, Finland, Taiwan and India.
  7. In addition to burglary protection ratings, UL also rates safes for their fire resistance protection. Class 350 safes protect paper documents, Class 150 safes protect magnetic tape and photographic film, while Class 125 safes protect floppy disks. In addition to the Class Rating, safes obtain an hourly rating for fire resistance-anywhere from 30 minutes to four hours.
  8. Another cool test UL runs on safes is an impact test. This test simulates a safe falling though multiple stories of a building-resulting from a fire that has weakened the structure. After the safe is heated to 2,000 degrees Fahrenheit in a furnace, it's raised three stories and dropped onto a pile of bricks. In order to meet the requirement, the safe can't pop open. Temperatures inside can't rise to above 300 degrees Fahrenheit and sample papers left inside have to be readable.
  9. The specialized suits you sometimes find technicians wearing are not just for show. Their entire ensemble, including protective coat, helmet and gloves, protects the crew against the adverse effects of sparking. After all, safety can't be taken for granted, even within the walls of UL.
  10. Safes are just one of the 19,000 product categories that UL tests and certifies. While UL's burglary protection team cracks combinations, shatters glass and fires .44-caliber bullets at body armor, other UL engineers and technicians keep busy testing everything from TVs, coffee makers and holiday light strings to fire extinguishers, medical CAT scan equipment and building materials.


Security On Sale....

A little over 10 years ago we posted an article (below) that included a video about quality versus garbage products, that has seen  a significant number of page views and continues to be on of our multitude of viral posts.

The post was titled "Big Box Store Or Product Specialist?"

In the last 10 years, Amazon has grown to become one of the most competitive marketplaces for goods available. they have almost taken over from Wal-Mart, Home Depot, Lowes, Target, K-Mart, Sears etc, among other companies that have failed as a consequence.

Locksmiths and Safe Specialists across the planet have deliberately trained in their chosen vocations, to deliver quality services and products to the many discerning customers, demanding more from their security products

April 25, 2008

Many customers prefer to purchase their products today from the big box stores, primarily due to their more competitive prices.

The following video explains why you are better served by a professional security company with respect to your personal and business security requirements.

Whereas, the video is about safes specifically, the same applies to your doors, locks and keys.

The choice is yours. Big box or Security Specialist?

REMEMBER: You only get what you pay for! And "if you only want to pay peanuts, expect to get monkeys!"

I had a very pleasant experience with Master Key Systems. They came out, did the job (which took longer than expected) and they did not change the price they quoted me.

Danny was excellent! I called him on a Monday to fix a sliding glass door. He happened to have the exact part we needed (and it was not an easy find - we had looked everywhere) and he came over Tuesday evening. He stayed until 8:00 until the job was done, and cleaned up afterwards. He was courteous, professional, and efficient! I could not be happier!

The repairman was on time and did an excellent job of fixing a very stubborn door lock. He was persistent and cleaned up the work area afterwards. I would use this service again.

Brenda F (Saint Peters, MO) June 2011

Danny at Master Key Systems has succeeded in making the purchasing of our Meroni door locks, from Italy, an absolute breeze. Even though I live in Australia with a 16hr time difference and was ordering door knobs from Italy that weren't in stock, the whole process was faultless. Danny was prompt and efficient with all his emails and made sure we had covered every possible variable so that the product I received was exactly as required. I would have no hesitation in recommending Danny for your next purchase.
Patrick Carr (Canberra, Australia)

Your product really helped because I needed to secure a nurse's station adjacent to a waiting room and needed a pocket door. Unfortunately, no real options were available to lock a pocket door effectively that would keep me compliant with HIPAA and secure an area that stores medical supplies. This was vitally important as this particular waiting room was for "waiting detox patients". Thank you very much.

Danny was very polite and knew what the problem was and how to fix it. He also gave me some information about other issues that could arise with my door and locks. Will hire again if I ever need that type of work done.

I had an exterior basement door that dragged when opening and closing. The hinges were not fitting properly and the door frame had shifted, probably due to the age of the house.The screwswould not go far enough into the wall without hitting stone...even using a special drill bit. Dan worked a long time drilling and sanding to shore up the door as best as possible. I know it will never be perfect. He could have easily sold me a new door and the same issue would happen. He was honest, thorough, and did an excellent job without charging me a fortune. I'm satisfied with the door now. If you want an honest, experienced man, Then Dan is the man

I purchased the Cowdroy P697 Pocket door lock with key over the internet. I emailed questions before my purchase and was provided with the answers quickly by return email. The purchase was quick and easy and the lock was shipped immediatly. Installation is quick and easy. But you do need to convert millimeters to inches (use the internet) in the installation instructions. And the lock looks great and works great. I will do business with them again. THANK YOU
