I have worked with demand generation and growth marketing leader Gene Volfe, both as employees of the same company and as independent consultants working for other companies.
I asked him to review a short technology piece that I wrote, and he immediately found two gaps:
So perhaps this is a good time to ask the question: do certifications matter?
Does my HubSpot certification, or my graduate degree, or my undergraduate degree, or the super-secret certification that I’m still pursuing (more later), anything more than a (digital) piece of paper to hang on the wall? Is this a substantive achievement, or does it just show that I was successful playing the certification game?
My HubSpot certification only has true meaning if I use the knowledge while creating content.
Checking the purported identity against private databases, such as credit records.
Checking the person’s driver’s license or other government document to ensure it’s real and not a fake.
Checking the purported identity against government databases, such as driver’s license databases. (What if the person presents a real driver’s license, but that license was subsequently revoked?)
Perform a “who you are” biometric test against the purported identity.
If you conduct all four tests, then you have used multiple factors of authentication to confirm that the person is who they say they are. If the identity is synthetic, chances are the purported person will fail at least one of these tests.
Do you fight synthetic identity fraud?
If you fight synthetic identity fraud, you should let people know about your solution.
Bredemarket’s services are grouped into two distinct and separate functions: content marketing (blog posts, white papers, etc.) and proposals (RFI responses, RFP responses, sole source letters, etc.).
My division of my services makes sense in the real world. After all, in some employment situations, content marketing and proposals employ distinct and separate sets of employees.
But other companies are different. In fact, I’ve seen employment ads seeking marketing/proposals managers. Sounds like a lot of work, unless the company submits few proposals or performs minimal marketing.
And in many companies there are NOT dedicated proposals specialists. Which is why Bredemarket makes its money by helping the salespeople at these firms get the documents out.
Time for the truth
And if we’re truthful with ourselves, content marketing and proposals are pretty much the same thing.
I know this angers some people, who insist that they are content marketing professionals or proposal professionals, with all the proper certifications that a mere mortal could never attain. Or they did attain it, but it lapsed. Or is about to lapse unless I renew it in time.
But hear me out. I’m going to list four aspects of a particular document, and you tell me whether I’m talking about a piece of marketing content, or a proposal.
The document describes benefits the customer will realize.
The document targets one or more sets of people hungry for the solution.
The document shall be in Aptos 12 point, single spaced, with 1 inch margins, and shall not exceed 20 pages.
Guess what? From that description you CAN’T tell if it’s a piece of content or a proposal.
Yes, I know some of you thought item 4 was a dead giveaway because it sounded like an RFP requirement, but maybe some company’s brand guidelines dictate that the firm’s white papers must conform to that format. You never know.
And I know that when you get into the minutiae, there are certain things that proposal writers do that content marketers don’t have to worry about, and vice versa.
But at a high level, the content marketer already knows 90% of the things they need to know to write proposals. And vice versa.
I’m pausing activity on some Bredemarket social channels (and some related personal channels) that have no subscribers, exhibit no interest, or yield no responses.
This channel is unaffected, and may benefit from increased focus.
I’ve worked with rapid DNA since I was in Proposals at MorphoTrak, when our corporate parent Safran had an agreement with IntegenX (now part of Thermo Fisher Scientific). Rapid DNA, when suitable for use, can process a DNA sample in 90 minutes or less, providing a quick way to process DNA in both criminal and non-criminal cases.
But as I explain below, sometimes rapid DNA isn’t so rapid. In those cases, investigators have to turn to boring biometric technologies such as fingerprints instead. Fingerprints are a much older identification modality, but they still work.
Bredemarket recently purchased access to a Journal of Forensic Sciences article entitled “Advances in postmortem fingerprinting: Applications in disaster victim identification” (https://doi.org/10.1111/1556-4029.15513) by Bryan T. Johnson MSFS of the Federal Bureau of Investigation Laboratory in Quantico. The abstract (which is NOT behind the paywall) states the following, in part:
In disaster victim identification (DVI), fingerprints, DNA, and dental examinations are the three primary methods of identification….As DNA technology continues to evolve, RAPID DNA may now identify a profile within 90 min if the remains are not degraded or comingled. When there are true unknowns, however, there is usually no DNA, dental, or medical records to retrieve for a comparison without a tentative identity.
In the body of the paper itself (which IS behind the paywall), Johnson cites one example in which use of rapid DNA would have DELAYED the process.
DVI depends upon comparison of a DNA sample from a victim with a previous DNA sample taken from the victim. If this is not available, then the victim’s DNA is compared against the DNA of a family member.
Identifying foreign nationals aboard the MV Conception
When the MV Conception boat caught fire and sank in September 2019, 34 people lost their lives and had to be positively identified.
While most of the MV Conception victims were California residents, some victims were from Singapore and India. It would take weeks to collect and transport the DNA samples from the victims’ family members back to the United States for comparison against the DNA samples from the victims. Weeks of uncertainty during which family members had no confirmation that their relatives were among the deceased.
However, because the foreign victims were visitors to the United States, they had fingerprints on file with the Department of Homeland Security. Interagency agreements allowed the investigating agencies to access the DHS fingerprints and compare them against the fingerprints of the foreign victims, providing tentative identifications within three days. (Fingerprint identification is a 100+ year old method, but it works!) These tentative identifications were subsequently confirmed when the familial DNA samples arrived.
What does this mean?
The message here is NOT that “fingerprints rule, DNA drools.” In some cases the investigators could not retrieve fingerprints from the bodies and HAD to use rapid DNA.
The message here is that when identifying people, you should use ANY biometric (or non-biometric) modality that is available: fingerprints, DNA, dental records, driver’s licenses, Radio Shack Battery Club card, or anything else that provides an investigative lead or a positive identification.
AAL1 (some confidence). AAL1, in the words of NIST, “provides some assurance.” Single-factor authentication is OK, but multi-factor authentication can be used also. All sorts of authentication methods, including knowledge-based authentication, satisfy the requirements of AAL1. In short, AAL1 isn’t exactly a “nothingburger” as I characterized IAL1, but AAL1 doesn’t provide a ton of assurance.
AAL2 (high confidence). AAL2 increases the assurance by requiring “two distinct authentication factors,” not just one. There are specific requirements regarding the authentication factors you can use. And the security must conform to the “moderate” security level, such as the moderate security level in FedRAMP. So AAL2 is satisfactory for a lot of organizations…but not all of them.
AAL3 (very high confidence). AAL3 is the highest authenticator assurance level. It “is based on proof of possession of a key through a cryptographic protocol.” Of course, two distinct authentication factors are required, including “a hardware-based authenticator and an authenticator that provides verifier impersonation resistance — the same device MAY fulfill both these requirements.”
This is of course a very high overview, and there are a lot of…um…minutiae that go into each of these definitions. If you’re interested in that further detail, please read section 4 of NIST Special Publication 800-63B for yourself.
Which authenticator assurance level should you use?
NIST has provided a handy dandy AAL decision flowchart in section 6.2 of NIST Special Publication 800-63-3, similar to the IAL decision flowchart in section 6.1 that I reproduced earlier. If you go through the flowchart, you can decide whether you need AAL1, AAL2, or the very high AAL3.
One of the key questions is the question flagged as 2, “Are you making personal data accessible?” The answer to this question in the flowchart moves you between AAL2 (if personal data is made accessible) and AAL1 (if it isn’t).
So what?
Do the different authenticator assurance levels provide any true benefits, or are they just items in a government agency’s technical check-off list?
Perhaps the better question to ask is this: what happens if the WRONG person obtains access to the data?
Could the fraudster cause financial loss to a government agency?
Threaten personal safety?
Commit civil or criminal violations?
Or, most frightening to agency heads who could be fired at any time, could the fraudster damage an agency’s reputation?
If some or all of these are true, then a high authenticator assurance level is VERY beneficial.

With over 100 firms in the biometric industry, their offerings are going to naturally differ—even if all the firms are TRYING to copy each other and offer “me too” solutions.
I’ve worked for over a dozen biometric firms as an employee or independent contractor, and I’ve analyzed over 80 biometric firms in competitive intelligence exercises, so I’m well aware of the vast implementation differences between the biometric offerings.
Some of the implementation differences provoke vehement disagreements between biometric firms regarding which choice is correct. Yes, we FIGHT.
Let’s look at three (out of many) of these implementation differences and see how they affect YOUR company’s content marketing efforts—whether you’re engaging in identity blog post writing, or some other content marketing activity.
The three biometric implementation choices
Firms that develop biometric solutions make (or should make) the following choices when implementing their solutions.
Presentation attack detection. Assuming the solution incorporates presentation attack detection (liveness detection), or a way of detecting whether the presented biometric is real or a spoof, the firm must decide whether to use active or passive liveness detection.
Age assurance. When choosing age assurance solutions that determine whether a person is old enough to access a product or service, the firm must decide whether or not age estimation is acceptable.
Biometric modality. Finally, the firm must choose which biometric modalities to support. While there are a number of modality wars involving all the biometric modalities, this post is going to limit itself to the question of whether or not voice biometrics are acceptable.
I will address each of these questions in turn, highlighting the pros and cons of each implementation choice. After that, we’ll see how this affects your firm’s content marketing.
(I)nstead of capturing a true biometric from a person, the biometric sensor is fooled into capturing a fake biometric: an artificial finger, a face with a mask on it, or a face on a video screen (rather than a face of a live person).
This tomfoolery is called a “presentation attack” (becuase you’re attacking security with a fake presentation).
And an organization called iBeta is one of the testing facilities authorized to test in accordance with the standard and to determine whether a biometric reader can detect the “liveness” of a biometric sample.
(Friends, I’m not going to get into passive liveness and active liveness. That’s best saved for another day.)
Now I could cite a firm using active liveness detection to say why it’s great, or I could cite a firm using passive liveness detection to say why it’s great. But perhaps the most balanced assessment comes from facia, which offers both types of liveness detection. How does facia define the two types of liveness detection?
Active liveness detection, as the name suggests, requires some sort of activity from the user. If a system is unable to detect liveness, it will ask the user to perform some specific actions such as nodding, blinking or any other facial movement. This allows the system to detect natural movements and separate it from a system trying to mimic a human being….
Passive liveness detection operates discreetly in the background, requiring no explicit action from the user. The system’s artificial intelligence continuously analyses facial movements, depth, texture, and other biometric indicators to detect an individual’s liveness.
Pros and cons
Briefly, the pros and cons of the two methods are as follows:
While active liveness detection offers robust protection, requires clear consent, and acts as a deterrent, it is hard to use, complex, and slow.
Passive liveness detection offers an enhanced user experience via ease of use and speed and is easier to integrate with other solutions, but it incorporates privacy concerns (passive liveness detection can be implemented without the user’s knowledge) and may not be used in high-risk situations.
So in truth the choice is up to each firm. I’ve worked with firms that used both liveness detection methods, and while I’ve spent most of my time with passive implementations, the active ones can work also.
A perfect wishy-washy statement that will get BOTH sides angry at me. (Except perhaps for companies like facia that use both.)
If you need to know a person’s age, you can ask them. Because people never lie.
Well, maybe they do. There are two better age assurance methods:
Age verification, where you obtain a person’s government-issued identity document with a confirmed birthdate, confirm that the identity document truly belongs to the person, and then simply check the date of birth on the identity document and determine whether the person is old enough to access the product or service.
Age estimation, where you don’t use a government-issued identity document and instead examine the face and estimate the person’s age.
I changed my mind on age estimation
I’ve gone back and forth on this. As I previously mentioned, my employment history includes time with a firm produces driver’s licenses for the majority of U.S. states. And back when that firm was providing my paycheck, I was financially incentivized to champion age verification based upon the driver’s licenses that my company (or occasionally some inferior company) produced.
But as age assurance applications moved into other areas such as social media use, a problem occurred since 13 year olds usually don’t have government IDs. A few of them may have passports or other government IDs, but none of them have driver’s licenses.
But does age estimation work? I’m not sure if ANYONE has posted a non-biased view, so I’ll try to do so myself.
The pros of age estimation include its applicability to all ages including young people, its protection of privacy since it requires no information about the individual identity, and its ease of use since you don’t have to dig for your physical driver’s license or your mobile driver’s license—your face is already there.
The huge con of age estimation is that it is by definition an estimate. If I show a bartender my driver’s license before buying a beer, they will know whether I am 20 years and 364 days old and ineligible to purchase alcohol, or whether I am 21 years and 0 days old and eligible. Estimates aren’t that precise.
Fingerprints, palm prints, faces, irises, and everything up to gait. (And behavioral biometrics.) There are a lot of biometric modalities out there, and one that has been around for years is the voice biometric.
I’ve discussed this topic before, and the partial title of the post (“We’ll Survive Voice Spoofing”) gives away how I feel about the matter, but I’ll present both sides of the issue.
No one can deny that voice spoofing exists and is effective, but many of the examples cited by the popular press are cases in which a HUMAN (rather than an ALGORITHM) was fooled by a deepfake voice. But voice recognition software can also be fooled.
Take a study from the University of Waterloo, summarized here, that proclaims: “Computer scientists at the University of Waterloo have discovered a method of attack that can successfully bypass voice authentication security systems with up to a 99% success rate after only six tries.”
If you re-read that sentence, you will notice that it includes the words “up to.” Those words are significant if you actually read the article.
In a recent test against Amazon Connect’s voice authentication system, they achieved a 10 per cent success rate in one four-second attack, with this rate rising to over 40 per cent in less than thirty seconds. With some of the less sophisticated voice authentication systems they targeted, they achieved a 99 per cent success rate after six attempts.
Other voice spoofing studies
Similar to Gender Shades, the University of Waterloo study does not appear to have tested hundreds of voice recognition algorithms. But there are other studies.
The 2021 NIST Speaker Recognition Evaluation (PDF here) tested results from 15 teams, but this test was not specific to spoofing.
A test that was specific to spoofing was the ASVspoof 2021 test with 54 team participants, but the ASVspoof 2021 results are only accessible in abstract form, with no detailed results.
Another test, this one with results, is the SASV2022 challenge, with 23 valid submissions. Here are the top 10 performers and their error rates.
You’ll note that the top performers don’t have error rates anywhere near the University of Waterloo’s 99 percent.
So some firms will argue that voice recognition can be spoofed and thus cannot be trusted, while other firms will argue that the best voice recognition algorithms are rarely fooled.
What does this mean for your company?
Obviously, different firms are going to respond to the three questions above in different ways.
For example, a firm that offers face biometrics but not voice biometrics will convey how voice is not a secure modality due to the ease of spoofing. “Do you want to lose tens of millions of dollars?”
A firm that offers voice biometrics but not face biometrics will emphasize its spoof detection capabilities (and cast shade on face spoofing). “We tested our algorithm against that voice fake that was in the news, and we detected the voice as a deepfake!”
There is no universal truth here, and the message your firm conveys depends upon your firm’s unique characteristics.
And those characteristics can change.
Once when I was working for a client, this firm had made a particular choice with one of these three questions. Therefore, when I was writing for the client, I wrote in a way that argued the client’s position.
After I stopped working for this particular client, the client’s position changed and the firm adopted the opposite view of the question.
Therefore I had to message the client and say, “Hey, remember that piece I wrote for you that said this? Well, you’d better edit it, now that you’ve changed your mind on the question…”
Bear this in mind as you create your blog, white paper, case study, or other identity/biometric content, or have someone like the biometric content marketing expert Bredemarket work with you to create your content. There are people who sincerely hold the opposite belief of your firm…but your firm needs to argue that those people are, um, misinformed.
