Computer scientists at New York University and Michigan State University have trained an artificial neural network to create fake digital fingerprints that can bypass locks on cell phones. The fakes are called “DeepMasterPrints”, and they present a significant security flaw for any device relying on this type of biometric data authentication. After exploiting the weaknesses inherent in the ergonomic needs of cellular devices, DeepMasterPrints were able to imitate over 70% of the fingerprints in a testing database.

An artificial neural network is a type of artificial intelligence comprising computer algorithms modeled after the human brain’s ability to recognize patterns. The DeepMasterPrints system was trained to analyze sets of fingerprint images and generate a new image based on the features that occurred most frequently. This “skeleton key” could then be used to exploit the way cell phones authenticate user fingerprints.

In cell phones, the necessarily small size of fingerprint readers creates a weakness in the way they verify a print. In general, phone sensors only capture a partial image of a print when a user is attempting to unlock the device, and that piece is then compared to the phone’s authorized print image database. Since a partial print means there are fewer characteristics to distinguish it than a full print, a DeepMasterPrint needs to match fewer features to imitate a fingerprint. It’s worth noting that the concept of exploiting this flaw is not unique to this particular study; however, generating unique images rather than using actual or synthesized images is a new development.

The team involved in the study resulting in the DeepMasterPrint creation initiated it as part of the ongoing assessment of vulnerabilities in fingerprint recognition systems. Finding exploitable flaws and fixing them is a constant battle in all digital systems with a security component. With this reality in mind, the scientists determined that merely exposing the flaws of fingerprint systems would not provide an effective solution; a working example of how attacks could be executed provides more specific data for researchers to design around and protect against. Creating the DeepMasterPrint system was meant to address this need.

The results revealed by the DeepMasterPrint system are concerning for anyone relying on fingerprint authentication on their smartphones. Scientists compared the generated fake prints against templates generated by VeriFinger 9.0 SDK, Bozorth3, and Innovatrics IDKit 5.3 SKD, all of which are software systems used in fingerprint authentication systems worldwide. At a low false match rate, i.e., strict match requirements for authentication, the fake print generated by DeepMasterPrint could imitate 23% of the fingerprints in the test database. At a slightly higher false match rate that was still within standard phone authentication limits, the fake print imitated 77% of the test fingerprints.

The scientists in this study did not create physical fingerprints to try and unlock actual phones, leaving that work to be done in the near future. However, even though the successful DeepMasterPrints have yet to be tested in true applications rather than a virtual environment, the data gathered confirmed the initial security concerns which inspired the experiment. Fingerprints are being used as identity verification in a growing number of applications beyond cell phone security, i.e., unlocking entryways, payment authentication, etc. The DeepMasterPrint system is another tool to help researchers guard their security as biometric authentication continues to expand.

Tesla kicks Robotaxi geofence expansion into high gear in Austin

Tesla has nearly doubled its Robotaxi geofence in Austin for the second time less than two months after it initially launched.

Tesla has kicked the expansion of its Robotaxi geofence in Austin, Texas, into high gear, as it grew the service area once again early Sunday morning.

Tesla launched its Robotaxi platform in Austin on June 22, and less than a month later, it was able to expand it. After its first expansion, Tesla had a larger geofence than Waymo, which launched its driverless ride-hailing service to the public in Austin in March. Waymo expanded the week after Tesla’s first augmentation.

Now, Tesla has answered Waymo once again by developing its service area in Austin to an even larger size. We expected it, as just two weeks ago, CEO Elon Musk said that the company would be growing the Austin geofence, but did not give an indication by how much.

The first geofence in Austin was roughly 20 square miles. On July 14, when the first expansion took place, Tesla Robotaxi riders had roughly 42 square miles of downtown Austin available for travel.

On the morning of August 3, Tesla nearly doubled the geofence by growing it to roughly 80 square miles, according to Grok. For reference, Waymo’s current service area in Austin is about 90 square miles:

The expansion further extends the Southern portion of the geofence, going into suburban zones such as Barton Creek.

The continuous growth shows Tesla is prepared to extend its geofence in basically any direction. Now that it is going into suburban areas, we may get to see more Austin residents experience Robotaxi for an entire evening of activities, including pickup and dropoff at home.

The only question that remains is how much Tesla can expand at one time. The company seems to have the ability to push the geofence to a majority of Austin, but it maintains that safety is its biggest priority.

The company was spotted testing vehicles in the West Austin suburbs in areas like Marble Falls recently, indicating that Tesla could be expanding its service area to hundreds of square miles in the coming months.

Tesla to appeal jury verdict that held it partially liable for fatal crash

Tesla will appeal the decision from the eight-person jury.

Tesla will appeal a recent jury verdict that held it partially liable for a fatal crash that occurred in Key Largo, Florida, in 2019.

An eight-person jury ruled that Tesla’s driver assistance technology was at least partially to blame for a crash when a vehicle driven by George McGee went off the road and hit a couple, killing a 22-year-old and injuring the other.

The jury found that Tesla’s tech was found to enable McGee to take his eyes off the road, despite the company warning drivers and vehicle operators that its systems are not a replacement for a human driver.

The company states on its website and Owner’s Manual that Autopilot and Full Self-Driving are not fully autonomous, and that drivers must be ready to take over in case of an emergency. Its website says:

“Autopilot is a driver assistance system that is intended to be used only with a fully attentive driver. It does not turn a Tesla into a fully autonomous vehicle.

Before enabling Autopilot, you must agree to ‘keep your hands on the steering wheel at all times’ and to always ‘maintain control and responsibility for your vehicle.’ Once engaged, Autopilot will also deliver an escalating series of visual and audio warnings, reminding you to place your hands on the wheel if insufficient torque is applied or your vehicle otherwise detects you may not be attentive enough to the road ahead. If you repeatedly ignore these warnings, you will be locked out from using Autopilot during that trip.

You can override any of Autopilot’s features at any time by steering or applying the accelerator at any time.”

Despite this, and the fact that McGee admitted to “fishing for his phone” after it fell, Tesla was ordered to pay hundreds of millions in damages.

Tesla attorney Joel Smith said in court (via Washington Post):

“He said he was fishing for his phone. It’s a fact. That happens in any car. That isolates the cause. The cause is he dropped his cell phone.”

In total, Tesla is responsible for $324 million in payouts: $200 million in punitive damages, $35 million to the deceased’s mother, $24 million to their father, and $70 million to their boyfriend, who was also struck but was injured and not killed.

The family of the deceased, Naibel Benavides Leon, also sued the driver and reached a settlement out of court. The family opened the federal suit against Tesla in 2024, alleging that Tesla was to blame because it operated its technology on a road “it was not designed for,” the report states.

Despite the disclosures and warnings Tesla lists in numerous places to its drivers and users of both Autopilot and Full Self-Driving, as well as all of its active safety features, the operator remains responsible for paying attention.

CEO Elon Musk confirmed it would appeal the jury’s decision:

The driver being distracted is a big part of this case that seemed to be forgotten as the jury came to its decision. Tesla’s disclosures and warnings, as well as McGee’s admission of being distracted, seem to be enough to take any responsibility off the company.

The appeal process will potentially shed more light on this, especially as this will be a main point of emphasis for Tesla’s defense team.

Elon Musk echoes worries over Tesla control against activist shareholders

Elon Musk has spoken on several occasions of the “activist shareholders” who threaten his role at Tesla.

Elon Musk continues to raise concerns over his control of Tesla as its CEO and one of its founders, as activist shareholders seem to be a viable threat to the company in his eyes.

Musk has voiced concerns over voting control of Tesla and the possibility of him being ousted by shareholders who do not necessarily have the company’s future in mind. Instead, they could be looking to oust Musk because of his political beliefs or because of his vast wealth.

We saw an example of that as shareholders voted on two separate occasions to award Musk a 2018 compensation package that was earned as Tesla met various growth goals through the CEO’s leadership.

Despite shareholders voting to award Musk with the compensation package on two separate occasions, once in 2018 and again in 2024, Delaware Chancery Court Judge Kathaleen McCormick denied the CEO the money both times. At one time, she called it an “unfathomable sum.”

Musk’s current stake in Tesla stands at 12.8 percent, but he has an option to purchase 304 million shares, which, if exercised, after taxes, he says, would bump his voting control up about 4 percent.

However, this is not enough of a stake in the company, as he believes a roughly 25 percent ownership stake would be enough “to be influential, but not so much that I can’t be overturned,” he said in January 2024.

Musk’s concerns were echoed in another X post from Thursday, where he confirmed he has no current personal loans against Tesla stock, and he reiterated his concerns of being ousted from the company by those he has referred to in the past as “activist shareholders.”

Elon Musk explains why he wants 25% voting share at Tesla: “I just want to be an effective steward of very powerful technology”

The CEO said during the company’s earnings call in late July:

“That is a major concern for me, as I’ve mentioned in the past. I hope that is addressed at the upcoming shareholders’ meeting. But, yeah, it is a big deal. I want to find that I’ve got so little control that I can easily be ousted by activist shareholders after having built this army of humanoid robots. I think my control over Tesla, Inc. should be enough to ensure that it goes in a good direction, but not so much control that I can’t be thrown out if I go crazy.”

The X post from Thursday said:

There is a concern that Musk could eventually put his money where his mouth is, and if politicians and judges are able to limit his ownership stake as they’ve been able to do with his pay package, he could eventually leave the company.

The company’s shareholders voted overwhelmingly to approve Musk’s pay package. A vast majority of those who voted to get Musk paid still want him to be running Tesla’s day-to-day operations. Without his guidance, the company could face a major restructuring and would have a vastly new look and thesis.
