Encrypting images with chaos

Research published in the International Journal of Information and Computer Security details a way to encode an image using a chaotic cryptosystem that makes it harder for someone to illicitly break the encryption by boosting ...

Blockchain to the rescue of small publishers

As Australian book publishers grapple with global disruption, digital technologies, and economic uncertainty, QUT researchers are looking at how blockchain technology can help them survive and thrive.

Device to device power saving

When devices communicate they are usually configured to save power by first choosing an appropriate channel, connecting to each other, and then carrying out power control according to the quality of service (QoS) requirements ...

Carnegie Mellon tool automatically turns math into pictures

Some people look at an equation and see a bunch of numbers and symbols; others see beauty. Thanks to a new tool created at Carnegie Mellon University, anyone can now translate the abstractions of mathematics into beautiful ...

Algorithm quickly simulates a roll of loaded dice

The fast and efficient generation of random numbers has long been an important challenge. For centuries, games of chance have relied on the roll of a die, the flip of a coin, or the shuffling of cards to bring some randomness ...

Tightening up facial biometrics

Facial biometrics for security applications is an important modern technology. Unfortunately, there is the possibility of "spoofing" a person's face to the sensor or detection system through the use of a photograph or even ...

New and improved drone mapping software

For his thesis, an EPFL Ph.D. student has enhanced the accuracy and reliability of drone mapping—a technique that is gaining traction across many sectors of society.
