A group of researchers led by Professor Nasir Memon has come up with a unique solution that can make PIN unlocking more secure. It’s all about spatial frequency — the smartphone’s display beams two distinct layers of lock screen — one with the normal PIN-pattern code and the other one with a false PIN layout....

App keeps ‘shoulder surfers’ from spying your password
Researchers have created a smartphone application to combat “shoulder-surfing”—when someone else looks over your shoulder as you enter your phone’s password or other private digits, potentially even gleaning vital financial or personal information. … Nasir Memon, a professor of computer science and engineering at New York University’s Tandon School of Engineering, explains that the technology,...

BadNets: Identifying Vulnerabilities in the Machine Learning Model Supply Chain
Tianyu Gu, Brendan Dolan-Gavitt and Siddharth Garg Deep learning-based techniques have achieved stateof-the-art performance on a wide variety of recognition and classification tasks. However, these networks are typically computationally expensive to train, requiring weeks of computation on many GPUs; as a result, many users outsource the training procedure to the cloud or rely on pre-trained models that...

A network framework for dynamic models of urban food, energy and water systems (FEWS)
Rae Zimmerman, Quanyan Zhu and Carolyn Dimitri The urban food system addressed here centers on urban food processing, distribution and consumption (including food packaging and waste disposal) and as such addresses how food moves from processing and distribution centers to points of consumption and ultimately waste disposal within cities. The Food-Energy-Water Systems (FEWS) Nexus extends...

The Optical Illusion That Could Protect Your Passcodes: Researchers Reveal Keypad That Looks Different If Someone Looks Over Your Shoulder
Have you ever been worried about a stranger looking at what you’re typing on your phone, or looking over your shoulder while you punch in your pin code at the ATM? … “The traditional configuration of numbers on a keypad is so familiar that it’s possible for an observer to discern a PIN or access...

Tricking The Eye To Defeat Shoulder Surfing Attacks
Every ATM or smartphone user can attest to the discomfort of having a stranger standing close enough to observe a financial transaction — and potentially note a PIN or account number. Now researchers at the NYU Tandon School of Engineering have announced a first-of-its-kind application to combat such “shoulder-surfing,” whether in person or via a...

HIV-1-infected T-cells dynamics and prognosis: An evolutionary game model
Bahareh Khazaei, Javad Salimi Sartakhti, Mohammad Hossein Manshaei, Quanyan Zhu, Mehdi Sadeghi and Seyed Rasoul Mousavi Understanding the dynamics of human immunodeficiency virus (HIV) is essential for depicting, developing, and investigating effective treatment strategies. HIV infects several types of immune cells, but its main target is to destroy helper T-cells. In the lymph nodes, the infected T-cells interact with each other...
