Have You Ever Tried to Encrypt Your E-mail? It's Really Hard.

A layman's lament.


When it comes to privacy, I always suggest the simplest solutions: “Download this app” or “Use this service instead of that.” But when it comes to e-mail encryption, there's no easy way to break it down.

Yes, protecting your privacy online has never been so easy. Applications for iOS and Android devices, such as Signal, and built-in encryption functions for instant messaging, such as Off-The-Record (OTR), are perfect solutions to protect the privacy of the not-so-tech-savvy. However, setting up e-mail proves to be one of the biggest barriers for users. It takes a lot of mental energy to figure out, set up, and use PGP (Pretty Good Privacy) encryption for e-mail. Even by the end of the process, the system may require troubleshooting.

To underscore this point, a group of researchers tried to measure how difficult it would be for a group of people to setup PGP. In this study, the researchers “brought in pairs of participants and had them attempt to use Mailvelope to communicate with each other. Our results shown that ... modern PGP tools are still unusable for the masses.”

The test “demonstrated that when our test participants were given 90 minutes in which to sign and encrypt a message using PGP 5.0, the majority of them were unable to do so successfully.”

Event security expert Bruce Schneier says, “E-mail is fundamentally unsecurable.” Instead of trying to figure it out, he says, “I advise people who want communications security to not use e-mail, but instead use an encrypted message client like OTR or Signal.”

There are a lot of step-by-step pieces for securing your online life. One of my personal favorites is How to be Anonymous Online, a guide to Tor, Tails, and securing e-mail. But, as the researchers point out, “We do not believe that home users can be made to cooperate with extensive tutorials, but we are investigating gentler methods for providing users with the right guidance.”

The smaller and simpler, the more likely consumers will comply, the researchers write. I disagree.

The more designers integrate this encryption technology into users' systems, the more consumers will comply. The people want privacy, and everyone should be able to access it. But the architects and designers have a responsibility to help make sure their products are designed with this option.

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

Videos
  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.

Scientists study tattooed corpses, find pigment in lymph nodes

It turns out, that tattoo ink can travel throughout your body and settle in lymph nodes.

In the slightly macabre experiment to find out where tattoo ink travels to in the body, French and German researchers recently used synchrotron X-ray fluorescence in four "inked" human cadavers — as well as one without. The results of their 2017 study? Some of the tattoo ink apparently settled in lymph nodes.

As the authors explain in the study — they hail from Ludwig Maximilian University of Munich, the European Synchrotron Radiation Facility, and the German Federal Institute for Risk Assessment — it would have been unethical to test this on live animals since those creatures would not be able to give permission to be tattooed.

Because of the prevalence of tattoos these days, the researchers wanted to find out if the ink could be harmful in some way.

"The increasing prevalence of tattoos provoked safety concerns with respect to particle distribution and effects inside the human body," they write.

It works like this: Since lymph nodes filter lymph, which is the fluid that carries white blood cells throughout the body in an effort to fight infections that are encountered, that is where some of the ink particles collect.

Titanium dioxide appears to be the thing that travels. It's a white tattoo ink pigment that's mixed with other colors all the time to control shades.

The study's authors will keep working on this in the meantime.

“In future experiments we will also look into the pigment and heavy metal burden of other, more distant internal organs and tissues in order to track any possible bio-distribution of tattoo ink ingredients throughout the body. The outcome of these investigations not only will be helpful in the assessment of the health risks associated with tattooing but also in the judgment of other exposures such as, e.g., the entrance of TiO2 nanoparticles present in cosmetics at the site of damaged skin."
