Après les Pays-Bas, au tour de la Suède de fermer des prisons. Des idées qui feront peut-être leur chemin jusqu'en Amérique, un jour.

Intéressant considérant leur législation. On aurait peut-être (sûrement) quelque chose à apprendre.
 
Les Pays-Bas ferment des prisons dû au manque de criminels. Ils ont de l'espace pour environ 14 000 détenus mais n'en ont que 12 000.

Rubik's Cube and Image Encryption

Internet security is of great concern nowadays, especially after the recent headlines describing possible illegal activities by media sources and governments. To combat this intrusion on privacy, researchers are hard at work devising new encryption methods that provide the security users expect during online communication.

The "Rubik's Cube principle" forms the basis for a new encryption method for digital images described in a 2012 paper from researchers with Laval University in Canada.

This method repositions the pixels in a image by scrambling and rotating the pixels in a way similar to how one scrambles the Rubik's Cube, i.e., by rotating the cube to a new configuration.

The researchers discovered that this method achieves good encryption with perfect hiding ability and can defend well against a variety of cyber-attacks.

Title: A Secure Image Encryption Algorithm Based on Rubik's Cube Principle

Authors: Khaled Loukhaoukha, Jean-Yves Chouinard, Abdellah Berdai
Dept. of Electrical and Computer Engineering, Laval University, QC, Canada

Abstract

In the past few years, several encryption algorithms based on chaotic systems have been proposed as means to protect digital images against cryptographic attacks. These encryption algorithms typically use relatively small key spaces and thus offer limited security, especially if they are one-dimensional. In this paper, we proposed a novel image encryption algorithm based on Rubik's cube principle. The original image is scrambled using the principle of Rubik's cube. Then, XOR operator is applied to rows and columns of the scrambled image using two secret keys. Finally, the experimental results and security analysis show that the proposed image encryption scheme not only can achieve good encryption and perfect hiding ability but also can resist exhaustive attack, statistical attack, and differential attack.

Medical devices powered by the ear itself

For the first time, researchers power an implantable electronic device using an electrical potential - a natural battery - deep in the inner ear without impairing hearing. Possible applications are in cochlear implants, diagnostics, drug-delivery devices and implantable hearing aids.

“We have known for 60 years that this battery exists and that it’s really important for normal hearing, but nobody has attempted to use this battery to power useful electronics.”

The photo shows a close-up of the new chip, equipped with a radio transmitter, which is powered by the natural battery. The chip is small enough to fit in the cavity of the middle ear.
