pta issues six tips to secure mobile phones

PTA issues six tips to secure mobile phones. Pakistan Telecommunication Authority has disclosed useful tips for public as part of its awareness campaign to secure users’ mobile phones. Maximum number of cell phone users are facing security and privacy issues in the country.

This step is part of the campaign that PTA launched in early march where the authorities urged WhatsApp users to enable two-step security. PTA issues six tips to secure mobile phones are very useful and are generally recommended by cyber-security experts around the world.

A global media outlet TechRadar also declared 10 tips to secure mobile phone in 2014. However, this decision by telecom regulator of the country is a good step in right direction.

Following are the six tips issued by PTA:
1. Always lock your mobile using a “Pin/Password” to avoid its misuse.
2. Install Apps only from “trusted Apps stores”.
3. Turn-off Bluetooth connection of device when not in use.
4. Must encrypt data on internal and external media.
5. Timely installs updates/patches.
6. Always use a VPN on public Wi-Fi/un-trusted network.

By getting into details of the points, above-noted by PTA, it is always the best solution to use PIN/password/pattern to lock phone because other bio-metric technologies like fingerprint scanner and facial recognition setup could be easily fooled or misused.

Meanwhile, Bluetooth can also present major security risks as this wireless tech may connect with unwanted networks.

Therefore, it is recommended that Bluetooth must be turned off once used.

Installation of Android/iOS security updates and security patches is quite important as they secure phones and make them more invulnerable.

Moreover, the point that briefs use of “trusted apps” means that one must always install apps from Apple’s App Store or Google Play Store, other than these apps tend to be less secure.

However , Public Wifi hotspots have become one of major sources of data misuse and use of VPN to encrypt connections sounds like an impressive idea.

A new Einstein cross is found

A new Einstein cross is found

The study, which has collect images from Hubble Space Telescope with spectroscopic lens, a phenomenon predicted by Albert Einstein's theory of General Relativity.In this case, the observed effect is due to the alteration caused by a galaxy that acts like a magnifying glass amplifying and distorting, in four separate images in the form of a cross, the light of another galaxy located 20,000 million light years away.

One of the most striking conclusions of Albert Einstein’s theory of general relativity is that the trajectory of light curves in the presence of matter. And now A new Einstein cross is found.

This effect can be observed in the case of light emitted by a distant galaxy, when its light passes close to another galaxy on its way to the observer.

 The phenomenon is known as gravitational lensing, because it is comparable to the deviation of light rays by the classic glass lenses.

 Similarly, gravitational lenses act like magnifying glasses that change the size, shape, and intensity of the image of the distant object.

One of the most noticeable conclusions of Albert Einstein’s theory of general relativity is that the path of light curves in the presence of the matter. 

This effect can be observed in the case of light emitted by a distant galaxy, when light passes close to another galaxy on its way to the observer.

 The phenomenon is known as gravitational lensing, because it is comparable to the deviation of light rays by the classic glass lenses. Similarly, gravitational lenses act like magnifying glasses that change the size, shape, and intensity of the image of the distant object.

Depending on the degree of alignment of the two sources, multiple images of the distant source can be observed, such as four separate images in the form of a cross (hence the name “Einstein’s cross”), rings, or arcs. 

It is in general extremely difficult to spot a gravitational lens, because the separation between the images produced by the lens is usually very small, requiring high-resolution images to see them. 

It was precisely analyzing Hubble Space Telescope high-resolution images that it was possible to locate an asterism that looked like a new example of Einstein cross.

However, spotting four points of light in the shape of a cross positioned around a galaxy does not assure us that it is a lens, so we must show that the 4 images belong to the same object.

 To do this spectroscopic observations are needed. 

For this reason, a team of Italian scientists led by Daniela Bettoni of the Padova Observatory and Riccardo Scarpa of the IAC, decided to observe spectroscopically with GTC the supposed lens. 

According to Scarpa, 

The result could not have been better. The atmosphere was very clean and with minimum turbulence (seeing), which allowed us to clearly separate the emission of three of the four images. 

The spectrum immediately gave us the answer we were looking for, the same emission line due to ionized hydrogen appeared in all three spectra at the same wavelength. There could be no doubt that it was actually the same source of light“.

A new Einstein cross is found, named J2211-0350 according to its coordinates on the sky. 

The object acting as a lens turns out to be an elliptical galaxy located at a distance of approximately 7 billion light years (z = 0.556), while the source is at least 20 billion light years away (z = 3.03).

 “Normally the source is a quasar, it was with great surprise that we realized the source in this case was another galaxy, in fact a galaxy with very intense emission lines which indicates it is a young object still forming large amounts of stars“, explain Bettoni. 

Quite an achievement for GTC, considering only another lens of this type was known.

China Hints At Surprise Space Station Launch

China Hints At Surprise Space Station Launch into orbit later this year, sooner than previously thought, on a commercial-grade rocket that is structured to be more affordable than private rocket launch companies such as SpaceX.

On Monday Xinhua News Agency, the official state-run press agency of the people’s Republic of China, reported that China Hints At Surprise Space Station Launch.

And the China Manned Space Engineering Office (CMSEO) will send the core module of the now-in-development Chinese Space Station (CSS) to the launch site.

 The launch site is at Wenchang Space Launch Center in the second half of this year to prepare for the space station missions. 

Although the CSS had been expected to launch during 2020.

The China Academy of Launch Vehicle Technology (CALVT), confirmed on Tuesday. 

That it will test the Long March-5B heavy-lift rocket in the first half of 2019, making the launch the launch of CSS later in 2019 much more likely. 

However, China’s current space station, Tiangong-2 space lab, was launched in 2016 and is due to be deorbited in the second half of 2019. 

However, the CSS is designed to last for at least a decade.

Comparing to the International Space Station, CSS is smaller, and will have a main cabin called Tianhe-1 (Milky Way).

Which was shown off last year, and two laboratory modules. 

While six and occasionally seven astronauts can live on the ISS, only three will be able to stay simultaneously on the CSS. 

China intends to finish building the CSS by 2022.

NHA developed App to ensure road safety

NHA developed app to ensure road safety

National Highway Authority (NHA) has taken a unique step with launching mobile App, which inform travelers about road safety, fog, weather and traffic condition.

NHA developed App to ensure road safety ,the main reason behind this move is to serve commuters and ensure a safe journey on motorways and highways on the country,especially during foggy and smoggy conditions.

The application is structured to help travelers by timely notification of available scenarios,fed into the system by App Monitors of Nh&MP and displayed on user dashboard through virtual bulletin boards.

Messages cover blockades, closures, diversion, fog, blind spots, black spots, and congestions.

Authority ensuring safe journey for commuters, has also ensured placement of traffic signs including warning signs, regulatory signs and information signs to warn and help drivers of upcoming in roads, e.g. placement of chevrons on curves.

On sunday officials said placement of reflective pavement Markings on center lanes and road adges, placement of Cat Eyes along with Pavement markings to make night driving safe and placement of Delineators and Angle reflectors on new Jersey.

Barrier were also assured to help drivers during foggy season and night time.

NHA has provided lighting in urban areas to increase safety during foggy season while informatory boards, kilometer posts and gantry sign boards were also placed which are helpful during driving in foggy smoggy season, sources said. 

Weather/foggy conditions are determined through Variable Message Sign (VMS).

Similarly, highlighting the steps taken by National Highway & Motorway Police (NH&MP) the sources said these include: 

Public Service Vehicle (PSV) transporters are directed to put on fog lights in front as well as in rear.

In dense fog, when visibility is zero, slow moving and non-motorized vehicles are being parked at safe places i.e.petrol pumps or hotels till visibility is improved.

The vehicles carrying load projected outside vehicles dimension are not allowed to enter on National Highways during foggy season.

Effective coordination with Frontier Works Organization (FWO), Edhi, Rescue 1122 and Meteorological Departments to tackle any emergency situation.

The sources said special attention is being paid on briefing to road users about safety measures including: speed limits, use of fog lights, driving care in fog, safe distance, avoid unnecessary travelling etc.

 

Moreover, briefing to slow moving vehicles includes: use of reflectors/pasting of reflectors by NH&MP, avoid travelling on highway after sunset, use of hard shoulder/soft shoulder, guidance centers have been established with Helpline 130 facility for road users as well as general public to make themselves update through landline.

While Beat Control communicate the briefing officer about prevailing emergency situation and necessary instructions for road users.

The sources said status of fog point (point to point) is being conveyed well in time through electronic and print media (TV channels and FM) for convenience and safety of road users, black-spots are properly monitored and covered to avoid any attempt of robbery/dacoity on highways.

While special anti-crime squads are being deployed at crime black spots in order to avert any attempt of crime.

Moreover, maximum safety/precautionary measures like wearing of reflecting jackets and use of strobe/fog lights, hooter are being taken with extra vigilance and diligence by NH&MP officers.

National Highway and Motorway Police have also launched an App “NHMP Hamsafar”. The users can call on NH&MP helpline 130 by pressing this menu. This will connect the call to NH&MP Call Centre. 

The official channel allocated to NH&MP is FM-95 which operates round the clock with mandate to impart road safety awareness through entertainment and also transmit regular updates on national road network.

Huawei will use Samsung OLED displays in P30 and P30 pro

Huawei and Samsung seems to construcrt new ties with each. Huawei is going to unveil its first pair of flagships for the current year. we will see the P30 and P30 pro at an event in paris. It has been stated that the main concentration of the devices will be photography. The report has unveiled that the P30 and P30 pro will come with OLED screens made by Samsung.

Huawei will use Samsung OLED displays in P30 and P30 pro So this time is changing BOE and LG, who manufactured the OLED for the Mate 20 Pro.

However the decision of shifting to Samsung of Huawei still mystery. May the company will be thinking that Samsung can meet Huawei’s requirements without having to bring in another manufacturer.

Above all, Samsung is the biggest smartphone supplier in the industry. The company has the manpower to pull off the high demand.

Therefor, it will make the whole process easier and comfortable as Huawei has to deal with only one supplier.

In addition, it has also been reported in december that Apple will use a new Samsung-made AMOLED for the 2019 iPhone.

This shows that Samsung has high demand in the market for OLED screens.

Researchers developed more realistic sociable Virtual Reality

Researchers developed more realistic sociable Virtual Reality

Virtual reality (VR) has made many developments in last few years delivering everything from virtual cocktail bars to prosthetic limbs aid. However , in last run, virtual reality is an insulated experience as it brings user alone into a virtual world.

 

Canadian researchers invented a sphere they say can generate a more sociable Virtual Reality at the University of British Columbia and the University of Saskatchewan. 

Their gadget is a ball-shaped VR display that can permit ap to two users inside a virtual world.

Although there are currently other spherical VR displays, these are restricted to show an image only from a single viewpoint.

Virtual Reality:

 This novel developments uses advanced calibration and graphics rendering techniques to show a “distortion-free 3D image even when viewed from multiple angles.”

Sidney Fels, lead researcher an electrical and computer engineering professor at UBC said,“When you look at our globe, the 3D illusion is rich and correct from any angle.”

“This allows two users to use the display to do some sort of collaborative task or enjoy a multiplayer game, while being in the same space. 

It’s one of the very first spherical VR systems with this capability,” he added.

May be because it copy the many wonders that could be seen in a crystal ball, the researchers have named their new device Crystal.

 Just like its name, it contains of a custom-made 24-inch (600-millimeters) hollow ball-shaped display equipped with four high-speed projectors and one camera.

And the researchers are not intended to stop at two users. 

They are currently working on a new four user system.

 

According to researchers, the future applications of Crystal range from everything from virtual reality games to virtual surgery.

For the time being though, their main concern is teleconferencing application.

Ian Stavness, a computer science professor at the University of Saskatchewan and member of the research team said

 “Imagine a remote user joining a meeting of local users. At either location you can have a Crystal globe, which is great for seeing people’s heads and faces in 3D.”

Or you can have a team of industrial designers in a room, perfecting a design with the help of VR and motion tracking technology,” he added.

The researchers have progressive plans for their novel device.

We’re not saying that spherical VR will replace flat screens or headsets,” said Fels, adding “but we think it can be a good option for VR activities where you still want to see and talk to other people–be it at home or in the office, for work or play,” they said.

Application for finding stolen or snatched phone

Application for finding stolen and snatched phone

Lahore Police in association with Punjab Information Technology Board (PITB) has developed application which would be used for tracing and recovering snatched cell phones. "E-Gadget Monitoring System" is a multi-feature application which would be available android and iOS stores and all mobile dealers would be urged to upload all information of purchased phones along with picture of the customer.

Application for finding stolen or snatched phone will be launched. While addressing the introductory meeting of the app, Capital City Police Chief BA Nasir said.

 The app is launched in Lahore as pilot project and it will be used in other parts of the province after determining the success ratio.

Dr Inam Waheed, Lahore Deputy Inspector General Police briefed the media and traders about working of the app.

Moreover, the system consists of many amazing features as a sudden alert would be generated to the police control room on any possible selling of a snatched or stolen cell phone, Dr Inam said, adding that with this app major reduction in mobile phone related crimes was expected.

In addition, SSP (CRO), Ehsan Saif Ullah said shopkeepers will enter IMEI number of every cell phone and the app would verify that if any FIR is registered or not. 

In other words, on finding any FIR the app would make an alert and quick action will be taken against the culprit.

 “Shopkeeper would be considered innocent if he properly fed the data in the system” he assured.

UK police launched a new Internet safety policy for Infants

UK police launched a new Internet safety policy for Infants

UK police are getting children as young as four in new internet safety campaign structured to handle a "disturbing" rise in the number of babies caught up in online sexual exploitation.

UK police launched a new Internet safety policy for Infants. The cartoon launched on Wednesday, stars a small girl named Jessie who guides to go to a parent or trusted adult if they see something online which makes them feel “worried, scared or sad”.

 It does not contain sexual abuse, but support children to discuss and share fearful things they have seen while using internet.

Rob Jones, director at the National Crime Agency, while releasing the “Jessie and Friends” animation, said tech industry referrals. 

Incidents reported by tech companies to National Center for Missing and Exploited Children in the US of online child sexual abuse material in the UK had risen from 82,109 in 2017 to 113,948 in 2018.

He said to reporters, “We are seeing a change in behaviour which is very disturbing, which is the abuse of very, very young children,”he added “There is a cohort of offenders we have a growing understanding of, who are pursing pre-verbal and very young children with the explicit objective of contact abuse. As a result of that, we’ve developed a response.”

The NCA’s team has used perceptions into exploitation to structured a campaign that aims to increase flexibility in young children, They are working with more than 100,000 professionals consists of teachers, youth workers, police officers and sports coaches to multiply the education material around the country.

Mr Jones said, “The scale of the threat has grown, so arresting offenders is not the only answer to the problem.”

 He added that he was especially concerned by the level of sophistication shown by offenders in developing relationships with children, such as via chat functions within online games, before creating what he called an “imbalance in that relationship” and exercising “coercive control over children” that can involve eliciting pictures, blackmailing, and inciting sexual behaviour.

Police stated that they decided to minimize the age of children they were targeting from five to four after research in schools and nurseries revealed the impact of internet in the lives of four-year -olds. 

They said it was necessary begin the talks about safety before children had reached an age where they “become more independent and start communicating with others online”.

Emma Hardy of the Internet Watch Foundation praised the campaign, saying that since children can use the internet “long before they can ride a bike or go down the road unaccompanied”, it was important that internet safety is taught from an early age.
