Fingerprint scanners have become a common feature in smartphones, providing users with a convenient and secure way to unlock their devices. However, despite their popularity, fingerprint scanners are not foolproof and can be bypassed by determined hackers. In this article, we will explore five ways bad actors can bypass fingerprint scanners and provide tips on how to protect your fingerprint data.

One method that hackers use to bypass fingerprint scanners is by creating masterprints or DeepMasterPrints. These are synthetic fingerprints that can deceive sensors by mimicking common fingerprint features. Another technique involves forging fingerprints using 3D printing, where hackers can lift prints from surfaces and create fake molds to trick the sensor.

Brute force attacks via BrutePrint is another method used by attackers to bypass fingerprint authentication. This method takes advantage of flaws in the fingerprint system to try as many fingerprint images as needed until a match is found. Additionally, side-channel attacks with PrintListener can capture the sound of a finger swiping on a screen to extract fingerprint features, allowing attackers to reconstruct fingerprint patterns.

Furthermore, exploiting unsecured fingerprint data storage is a common way for attackers to bypass fingerprint scanners. If attackers gain access to unprotected fingerprint data, they can replicate fingerprints to bypass authentication. It is essential to choose trusted phone brands, keep your phone updated, and use strong antivirus software to protect your fingerprint data.

In conclusion, while fingerprint scanners provide a convenient and secure way to unlock devices, they are not infallible. It is crucial to take steps to protect your fingerprint data, such as using strong passwords, being cautious about who handles your phone, and only using fingerprint login with trusted apps. By following these security measures, you can help safeguard your biometric identity and reduce the risk of unauthorized access to your device.

Alexandria Ocasio-Cortez’s tough Bronx persona is under fresh scrutiny with a resurfaced childhood nickname from her suburban upstate New York upbringing casting doubt on that publicly portrayed image. The progressive champion’s latest spat with President Donald Trump over the Iran strikes again called into question her true upbringing when she declared on X she was a “Bronx girl" to make her a point against the president. The 35-year-old congresswoman wrote in part on X: "I’m a Bronx girl. You should know that we can eat Queens boys for breakfast. Respectfully," she said, referring to the president’s upbringing in Queens as she called for his impeachment over his decision to bypass Congress in authorizing U.S. strikes on Iranian nuclear facilities. Ocasio-Cortez was born in the Bronx but moved to Yorktown – which is nearly an hour outside New York City -- when she was 5 years old and went on to attend Yorktown High School where she graduated in 2007. She was considered an accomplished student there and well thought of by teacher Michael Blueglass, according to a 2018 report by local media outlet Halston Media News. “There, known by students and staff as ‘Sandy,’ she was a member of the Science Research Program taught by Michael Blueglass," the report states. “She was amazing," Blueglass said, per the report. “Aside from her winning one of the top spots and going to the [Intel International Science and Engineering Fair], she was just one of the most amazing presenters in all of the years I've been at Yorktown. Her ability to take complex information and explain it to all different levels of people was fantastic." After high school, Ocasio-Cortez attended Boston University, where she majored in economics and international relations, per the report. Ocasio-Cortez’s “Sandy" nickname — which carries a more suburban and preppy tone — appears to undercut her politically crafted image as a tough, inner-city fighter, one she has portrayed since her famous 2018 congressional campaign where she eventually ousted former 10-terms Congressman Joe Crowley. New York GOP Assemblyman Matt Slater, who now represents Yorktown, added to the scrutiny of Ocasio-Cortez’s persona in the wake of her brash with Trump and released images of Ocasio-Cortez from his high school yearbook. He claimed he and the rising Democratic star attended Yorktown High School at the same time when she was a freshman and he was a senior. "I saw the attacks on the president and her [Ocasio-Cortez] claims that she's a big, tough Bronx girl," said Slater. "To sit there and say that she’s a Bronx girl is just patently ridiculous." "Everybody in our community knows this is just a bold-face lie," said Slater on "Fox & Friends First" last week. "She grew up in Yorktown, she was on my track team." "She's lying about her background, she's lying about her upbringing," Slater claimed. Slater’s post sent social media ablaze and prompted Ocasio-Cortez to respond after an image if her family’s home was posted online. “I’m proud of how I grew up and talk about it all the time," Ocasio-Cortez wrote on X Friday responding to the post. “My mom cleaned houses and I helped. We cleaned tutors’ homes in exchange for SAT prep." “Growing up between the Bronx and Yorktown deeply shaped my views of inequality & it’s a big reason I believe the things I do today!"
