“[A]dversarial Gait Recognition has arisen as a major challenge in video surveillance systems, as deep learning-based gait recognition algorithms become more sensitive to adversarial attacks.”
So Zeeshan Ali and others are working on IMPROVING gait-based adversarial attacks…the better to counter them.
“Our technique includes two major components: AdvHelper, a surrogate model that simulates the target, and PerturbGen, a latent-space perturbation generator implemented in an encoder-decoder framework. This design guarantees that adversarial samples are both effective and perceptually realistic by utilizing reconstruction and perceptual losses. Experimental results on the benchmark CASIA-gait dataset show that the proposed method achieves a high attack success rate of 94.33%.”
Now we need to better detect these adversarial attacks.
An authentication factor is a discrete method of authenticating yourself. Each factor is a distinct category.
For example, authenticating with fingerprint biometrics and authenticating with facial image biometrics are both the same factor type, because they both involve “something you are.”
But how many factors are there?
Three factors of authentication
There are some people who argue that there are only really three authentication factors:
Something you know, such as a password, or a personal identification number (PIN), or your mother’s maiden name.
Something you have, such as a driver’s license, passport, or hardware or software token.
Something you are, such as the aforementioned fingerprint and facial image, plus others such as iris, voice, vein, DNA, and behavioral biometrics such as gait.
Somewhat you why, or a measure of intent and reasonableness.
For example, take a person with a particular password, ID card, biometric, action, and geolocation (the five factors). Sometimes this person may deserve access, sometimes they may not.
The person may deserve access if they are an employee and arrive at the location during working hours.
That same person may deserve access if they were fired and are returning a company computer. (But wouldn’t their ID card and biometric access have already been revoked if they were fired? Sometimes…sometimes not.)
That same person may NOT deserve access if they were fired and they’re heading straight for their former boss’ personal HR file.
Or maybe just five factors of authentication
Now not everyone agrees that this sixth factor of authentication is truly a factor. If “not everyone” means no one, and I’m the only person blabbering about it.
So while I still work on evangelizing the sixth factor, use the partially accepted notion that there are five factors.
“We provide the world’s leading news coverage and information on the global biometric technology market via the web and an exclusive daily newsletter. Our daily biometrics updates, industry perspectives, interviews, columns and in-depth features explore a broad range of modalities and methods, from fingerprint, voice, iris, and facial recognition, to cutting-edge technologies like DNA analysis and gait recognition, related identification tools such as behavioral biometrics, and non-biometric identification methods such as identity document verification and telephone forensics. Our coverage touches on all applications and issues dealt with in the sector, including national security, mobile identity, and border control, with a special emphasis on UN Sustainable Development Goal 16.9 to provide universal digital identification and the ID4Africa movement.”
Over the last ten years, there have been two instances in which I have been newsworthy.
2015 with MorphoTrak
The first occurred in 2015, when my then-employer MorphoTrak exhibited an airport gate called MorphoWay at a conference then known as connect:ID. At the 2015 show, I demonstrated MorphoWay for Biometric Update’s videographer.
Me at connect:ID, 2015.
“In the video, Bredehoft scans his passport through the document reader, which checks the passport against a database to verify that it is, in fact, a CBP-authorized document.
“Once verified, the gates automatically open to allow Bredehoft to exit the area.”
2025 with Bredemarket
The second occurred ten years later in 2025, when I wrote a guest opinion piece entitled “Opinion: Vendors must disclose responsible uses of biometric data.” As I previously mentioned, I discussed the need to obtain consent for use of biometric data in certain instances, and noted:
“Some government agencies, private organizations, and biometric vendors have well-established procedures for acquiring the necessary consents.
“Others? Well…”
Biometric Update didn’t create a video this time around, but I did.
Biometric vendors…
2035???
So now that I’ve established a regular cadence for my appearances in Biometric Update, I fully expect to make a third appearance in 2035.
Because of my extensive biometric background, I predict that my 2035 appearance will concern the use of quantum computing to distinguish between a person and their fabricated clone using QCID (quantum clone identification).
No video yet, because I don’t know what video technology will be like ten years from now. So here’s an old fashioned 2D picture.
