No, Tongue Identification Is NOT Widely Accepted

Remember tongue identification, which I discussed in 2023? Supposedly you can identify people based upon the shape and texture of their tongues. Unfortunately for the proponents, I don’t know that this has ever been tested with a subject size greater than 20 participants.

But that doesn’t stop people from talking about tongue identification as established fact.

A blog post (I won’t link to it) makes statements such as this:

The human tongue…has unique features that are different for each person.

Again without a shred of evidence.

Of course, the same blog post also praises bite mark analysis as an established identification method. Ignoring what scientists say:

“A likely next candidate for elimination is bitemark identification….An important National Academies review found little scientific support for the field. The Texas Forensic Science Commission recently recommended a moratorium on the admission of bitemark expert testimony….This article describes the (legal) basis for the rise of bitemark identification and the (scientific) basis for its impending fall. The article explains the general logic of forensic identification, the claims of bitemark identification, and reviews relevant empirical research on bitemark identification—highlighting both the lack of research and the lack of support provided by what research does exist. The rise and possible fall of bitemark identification evidence has broader implications—highlighting the weak scientific culture of forensic science and the law’s difficulty in evaluating and responding to unreliable and unscientific evidence.”

So don’t get all excited about tongue identification just yet.

Some 2.45 Things You Do

A study entitled “Browsing behavior exposes identities on the web” (also cited by Biometric Update) offers an informative view of how “something you do” can identify you when combined with other things you do.

“Though most users are unique in their four most-visited domains, we find that we often need fewer data points for user identification. To determine how many domains are needed to pinpoint a user, we examine fingerprints at the individual level. For each unique user i, we randomly select a domain from their fingerprint and group all unique users who have that domain in their fingerprints (see Methods). Then, we select another most-visited domain from user i and narrow our group to those with both domains (Fig. 1c). We repeat this step, incrementally adding domains, until we isolate user i. At this point, we have a set of domains which exists only within user i’s fingerprint. Our analysis shows that we need an average of 2.45 steps to identify a unique user within the data set (Fig. 1d). This finding indicates that although four domains guarantee uniqueness, users’ distinct online habits facilitate their identification with fewer domains.”

Think about the four domains that YOU visit the most. If you don’t know what they are, Chrome users can visit chrome://site-engagement/ and order the list. I can almost guarantee that one of my four most-visited websites is NOT one of yours.

This Morning’s Camera Fun

This morning I went to join my 6:00 am client / client’s client meeting and found my camera wasn’t working in Teams.

After the meeting I discovered that it wasn’t working in Google Meet either.

So I turned the computer off and turned it on again…still not working.

After exploring a bit, Windows told me that something else was using the camera…and also told me that something had turned the camera off. I assumed the latter was the correct diagnosis.

After exploring some more, including every function key combination, I found a barely visible switch.

Thanks, Google Gemini:

…there is no keyboard button to turn the camera off.

Instead, HP placed a physical privacy shutter directly at the top of the laptop screen.

Where to look and how to use it:

  1. Look at the very top bezel (border) of your laptop screen, right where the camera lens is centered.
  2. Directly next to or built into the glass over the lens, you will see a tiny manual sliding tab.

I slid the tab to the right, and my camera was working again.

I must have slid the shutter to the left yesterday when I transported the computer away from and back to my home.
