Respiratory illness could be prevented from Microsoft Xbox Kinect

London: Microsoft’s Xbox Kinect, a popular sensor-based gaming console – can assess the respiratory function of patients and spot conditions such as cystic fibrosis, researchers including an Indian origin scientist report.

The team from the University of Warwick and the Institute of Inflammation and Ageing, University of Birmingham and Heart of England NHS Foundation Trust (HEFT) have developed a method to use the gaming device.

The system consists of four Kinect sensors which are capable of quickly creating a 3D image of a patient’s torso.

This enables physicians to measure and assess how a chest wall moves.

In tests, it has proven to be as accurate as a patient breathing into a spirometer, the current method used, but providing additional information about the movement of the chest, which could help in identifying numerous respiratory problems.

“In screening, diagnostics, monitoring therapy and providing bio feedback, the Xbox can be used in any condition affecting breathing, “said Babu Naidu, chief investigator, a thoracic surgeon at HEFT.

“We have developed a low-cost prototype which provides a more comprehensive measurement of a patient’s breathing then existing methods, “added Dr Chris Golby at the Institute of Digital Healthcare, University of Warwick.

Spirometry is the technique most commonly used to treat lung diseases including chronic bronchitis, emphysema and chronic obstructive airways.

The academics put their prototype to trial initially using a resuscitation mannequin, then on healthy volunteers and adults with cystic fibrosis.

As the Kinect has an infrared beam it allowed them to measure changes in distances across the chest wall.

The system uses four sensors which allow measurement of movement from more than one viewpoint.

Using off-the-shelf and bespoke software they were able to create a 3D image of a patient’s chest wall.

“It is also potentially very useful in assessing changes in respiratory physiology that occur during exercise. This is in contrast with existing systems which rely on data from one viewpoint,” Dr Golby noted in a paper published in the journal Medical & Biological Engineering & Computing.

The team is now planning to develop their prototype further using Microsoft’s new version of the Kinect, working with cystic fibrosis and other respiratory conditions.(IANS)

Data breaches forced governments and enterprises to focus on cyber security

In the first major attack of the year, the world reeled under “WannaCrypt” that locked files on computers.

Mega cyber attacks such as “WannaCrypt” and “Petya” this year forced governments and enterprises globally, including in India, to focus and invest more in bolstering their security networks. In the first major attack of the year, the world reeled under “WannaCrypt” that locked files on computers. Hundreds of thousands of computers were infected with the malware in May. The primary reason for this attack being successful was not the software but human error.

On March 14 this year, Microsoft released a security update which addressed the vulnerability in the 16-year-old Windows XP operating system. Once the patch for the vulnerability was released, hacker group “Shadow Brokers” exploited this loophole and wreaked havoc in 150 countries. Those who installed the update were saved, while several who did not, fell prey to the attack.

Soon after the “WanaCrypt” attack, tens of thousands of computers globally were affected by the “Adylkuzz attack” that shut down SMB networking to prevent further infections with other malware (including the WannaCrypt worm). While Europe and major parts of the world struggled with another big ransomware attack called “Petya”, India also bore the brunt. Some Indian servers were down owing to the Petya attack.

The Shipping Ministry said operations at one of the container terminals at Mumbai’s Jawaharlal Nehru Port Trust (JNPT) was affected by Petya. Companies like Genesis BM, a public relations firm, had to shut down systems in India after their international servers were attacked. The month of May saw another cyber attack when a malware called “Judy” hit over 36.5 million Android-based phones, making its way through Google Play Store.

In August, the “Locky” ransomware, once considered almost defunct, sent over 23 million emails with the malware to the US workforce in just 24 hours. It scrambled the contents of millions of computers and demanded payment to unlock it.

A group of hackers leaked the “Game of Thrones” script, along with 1.5TB of HBO data that included other popular TV shows. The hacking group demanded approximately $6.5 million worth of Bitcoins from HBO. A group of hackers also penetrated Equifax — one of the largest credit bureaus in the world — and stole personal data of 145 million people. Accountancy firm Deloitte was also targeted by a sophisticated hack that compromised the confidential emails and plans of some of its blue-chip clients and the attack went unnoticed for months.

In November, Yahoo agreed that it was attacked in 2013 wherein criminals had information about all three billion accounts. In another massive attack, hackers stole the personal data of 57 million customers and drivers from Uber Technologies. The breach was concealed for more than a year.

Most companies fall victim to cyber attackers either because of unpatched software with known vulnerabilities or because of the human factor like people falling victim to phishing emails, Finland-based cybersecurity firm F-Secure said.

Later in the year, the enterprise cybersecurity company FireEye said Chinese advanced persistent threat (APT) groups that have allegedly been creating cyber havoc internationally will shift their focus in 2018 to countries like India and Hong Kong and groups seen as a threat to Beijing’s influence over global markets.

Slowly becoming aware of emerging cyber threats, organisations worldwide will spend $96.3 billion on security in 2018 — an increase of eight per cent from 2017, according to a Gartner forecast. More than 60 per cent of organisations globally will invest in multiple data security tools by 2020 — up from 35 per cent today, it added.

“Cyber attacks such as WannaCry and NotPetya, and most recently the Equifax breach, have a direct effect on security spend because these types of attacks last up to three years,” the market research firm said. To ward off future attacks, the Indian government set up NIC-CERT centre to monitor, detect and prevent cyber attacks on government networks.

NIC-CERT will work in close coordination and collaboration with sectoral CERTs and CERT-In. Prime Minister Narendra Modi inaugurated the fifth edition of the Global Conference on Cyber Space (GCCS) in New Delhi in November that witnessed top global security experts deliberating on ways to fight cybersecurity.
