“The design decision referenced in The Guardian story prevents millions of mesغير مجاز مي باشدes from being lost, and WhatsApp offers people security notifications to alert them to potential security risks,” the company added.What is interesting to note is that the Signal private mesغير مجاز مي باشدing app unlike WhatsApp, isn’t vulnerable to the same attack. On the contrary, WhatsApp will send that mesغير مجاز مي باشدe anyway.WhatsApp’s end-to-end encryption relies on a set of keys that verify whether the sender and the receiver are, who they claim to be.WhatsApp further clarified stating that the company has even published a technical white paper of its encryption design. However, The Guardian piece describes a believable attack that WhatsApp’s given encryption system cannot stop. But the receiver’s encryption key will change if the app is re-installed, the handset is replaced or there is a change of mobile number.Photo credit: Open Whispers SystemIn other words, if an attacker gained access to a WhatsApp server, he/she could forcibly reset the keys used to encrypt mesغير مجاز مي باشدes and install himself as the user thereby gaining access to the future mesغير مجاز مي باشدes exchanged between parties.“If WhatsApp is asked by a government agency to disclose its mesغير مجاز مي باشدing records, it can effectively grant access due to the change of keys,” Boelter said. WhatsApp gives users the option to be notified when those changes occur. But the receiver’s encryption key will change if the app is re-installed, the handset is replaced or there is a change of mobile number. But just like any tech it’s not perfect.However, WhatsApp rebutted these accusations.

The Guardian posted an article earlier this week which left majority of the WhatsApp users in a state of panic. (Photo credit: Open Whisper System)The catch here is that the sender is notified of the key change only if the ‘Key Change Notification’ feature is on. In such cases, WhatsApp generates a new key for that user. Any attempt to intercept mesغير مجاز مي باشدes in transmit by the server is detectable by the sender, just like with Signal, PGP, or any other end-to-end encrypted communication system,” Marlinspike said.What is he really referring to?WhatsApp’s end-to-end encryption essentially relies on the generation of unique keys.WhatsApp’s backdoor issue, not really an issueMoxie Marlinspike, founder of Open Whisper Systems in contrast to The Guardian piece states, “This is something any public key cryptography system has to deal with. Once the mesغير مجاز مي باشدe is re-sent, the sender is notified of the receiver’s key change.At the same time, American digital rights group, Electronic Frontier Foundation said Jonathan Zdziarski, a leading independent security researcher and forensics expert.The report quoted cryptography and security researcher at the University of California Tobias Boelter as claiming that due to a given “security vulnerability,” Facebook-owned WhatsApp could intercept and read encrypted mesغير مجاز مي باشدes that the users exchanged on the app.

The chatting app also offers users an added layer of verification through options like ‘Safety Number’ or ‘Security Code’ that both the parties can visually check and verify Combined Grinding Machine to know if they are using the same security code. In the case of former, when the client detects a new key, it will block the mesغير مجاز مي باشدe rather than risk sending it across, unsecured. The chatting app has been transparent about the government’s requests it receives, publishing data about these requests in the ‘Facebook Government Requests Reports. Privacy campaigners feel that this vulnerability is a huge threat to freedom of speech and warned that it could even be used by government agencies as a “backdoor” to snoop on users. During this time the sender’s encrypted mesغير مجاز مي باشدes are in a state of void, waiting to be re-sent.” “The fact that WhatsApp handles key changes is not a ‘backdoor,’ it is how cryptography works.He further states that the only reasonable question to ask in this scenario is whether WhatsApp should just delete mesغير مجاز مي باشدes in transit or hold them until a new key is generated. “No question about it, this is good tech. This is done with the help of a Signal protocol developed by Open Whispers System, that is traded and verified between users to guarantee communications are secure and cannot be intercepted by a middleman.’So where does the issue really lie?WhatsApp’s end-to-end encryption relies on a set of keys that verify whether the sender and the receiver are, who they claim to be.”. In a statement WhatsApp said that it would fight any government request to create a backdoor

Perhaps, for the first time in his 46 years, Rahul Gandhi was getting to know his own country, and the people he is likely to lead in the very near future. But it’s a risk worth taking. Least of all, self-styled analysts and NaMo fans, who continued to make fun of his efforts, while shaking their heads in mock-sympathy, and tirelessly repeating the same old lines, “What a pity Pappu is the face of the Congress Party.Come on… wipe that sheepish grin off your face. Who can forget that dramatic moment when, after a 40-minute impassioned speech in which he made several digs at the PM, he rushed across the floor of the House and hugged a very startled and far from amused Narendra Modi? Of course, that moment captured on camera made it to the front pages of every major daily and was widely dissected. It was Advantage Rahul. Of course, cynics sniggered. He looked sincere — maybe he WAS sincere, like China CNC Universal Cylindrical Grinding Machine he actually cared about their lives and miserable condition. The new, articulate and relaxed Rahul started winning hearts (read: potential votes).

We have the choice to vote for a man who may not be brilliant, but has heart and speaks the language of love. Everybody…or at least all those of you who had written off Rahul Gandhi and called him all sorts of unkind names ever since he decided he was going to keep his non-stop partying on hold and actually get into the family business in a serious way. Placing faith in Rahul Gandhi involves a gigantic risk. Gradually, a new body language began to evolve and his limited Hindi vocabulary took a quantum leap! He seemed as surprised by his fluency in a language which he may only have used with house help, to order breakfast or an aperitif. Inadvertently, he became India’s new age poster boy for the “Make Love, Not War” hippie movement of the distant 70s, that had captured the imagination of global youth, tormented by the violence of the Vietnam war. Now you have one!How did the tide turn… and when? I would say, Rahul Gandhi’s “jadoo ki jhappi” on July 20th did the trick. We are at that inflexion point right now. Simultaneously, he also discovered his inner voice, like his mother famously had, when faced with a dilemma (“to be or not to be the Prime Minister”, that was the question). He’s the one having the last laugh now. American politics changed virtually overnight, and the Vietnam war ended finally. Or we can go right back to a bunch of canny people we trusted… but who didn’t honour our precious trust. I can see chillums and flower power staging a huge comeback, with masses of young, guitar-strumming, long-haired people wearing Hare Rama guru shirts and beaded headbands, as they gather at India Gate for what were described as “love-ins” in those days. Please don’t be mean and say their mental age matches!I remember having an animated discussion about “the hug” with a small group of political pundits (stuffed shirts with fixed views) the same evening. It’s possible a great big parivartan had indeed taken place.

That was Rahul’s seminal moment, and the beginning of the end for NaMo. All the men felt Rahul had completely blown it! They found both gestures terribly childish, even foolish, and said Rahul had effectively committed political hara ********** and made an ass of himself. But the aam janta got used to seeing him engaging in fiery debates …. Amusingly enough, there are only two perceived “brats” in India right now — both are media superstars with a vast fan following — Taimur Ali Khan and Rahul Gandhi. Of course, all this is fluff.I think it’s kind of cool. We may have our very own, laidback hippie Prime Minister next year. “Give peace a chance” … sang John Lennon years ago, and the world sang along with him. Can’t they find a more competent leader? India needs a strong Opposition!”Well, guess what baby.. PM Modi’s lame and rather clumsy comeback did nothing to salvage the situation subsequently. Young people are saying directly or indirectly that they are done with the politics of hate, the venom-spewing of netas, and the ugly face of divisive politics. Well… there was “the hug”… and then came “the wink”. Rahul sensibly ignored those belligerent personal attacks and continued to flash those dimples! This, in retrospect, turned out to be a great strategy — they simply could not get a rise out of him! He soldiered on, rushing about like an eager college kid on a study tour. It’s time to vote with our dil. But even at that stage, nobody took him seriously. We tried voting with our dimaag.

Eduardo Bernal wrote in an email Tuesday.Amazon’s decision to market a powerful face recognition tool to police is alarming privacy advocates, who say the tech giant’s reach could vastly accelerate a dystopian future in which camera-equipped officers can identify and track people in real time, whether they’re involved in crimes or not. can be then alerted in real time to events that are happening,” he said.”That could have potentially dire consequences for minorities who are already arrested at disproportionate rates, immigrants who may be in the country illegally or political protesters, they said.Amazon’s technology isn’t that different from what face recognition companies are already selling to law enforcement agencies.”Orlando has a network of public safety cameras, and in a presentation posted to YouTube this month, Ranju Das, who leads Amazon Recognition, said the company would receive feeds from the cameras, search them against photos of people being sought by law enforcement and notify police of any hits.Some police departments, including Seattle, have policies that bar the use of real-time facial recognition in body camera videos.“This raises very real questions about the ability to remain anonymous in public spaces,” Garvie said.The American Civil Liberties Union and other privacy advocates on Tuesday asked Amazon to stop marketing Recognition to government agencies, saying they could use the technology to “easily build a system to automate the identification and tracking of anyone..The statement said some agencies have used the program to find abducted people, and amusement parks have used it to find lost children.“It’s about recognizing people, it’s about tracking people, and then it’s about doing this in real time so that the law enforcement officers .

“As this is a pilot and not being actively used by OPD as a surveillance tool, there is no policy or procedure regarding its use as it is not deployed in that manner,” Bernal wrote.”In an emailed statement, Amazon Web Services stressed that it requires all of its customers to comply with the law and to be responsible for the use of its products.Last year, the Orlando, Florida, Police Department announced it would begin a pilot program relying on Amazon’s technology to “use existing city resources to provide real-time detection and notification of persons-of-interest, further increasing public safety.The Washington County Sheriff’s Office in Oregon has used it to quickly compare unidentified suspects in surveillance images to a database of more than 300,000 booking photos from the county jail — a common use of such China Precision Grinding Machines Manufacturers technology around the country — while the Orlando Police Department in Florida is testing whether it can be used to single out persons-of-interest in public spaces and alert officers to their presence.A year later, deputies were using it about 20 times a day — for example, to identify burglary suspects in store surveillance footage. British broadcaster Sky News used Recognition to help viewers identify celebrities at the royal wedding of Prince Harry and Meghan Markle last weekend. But its vast reach and its interest in recruiting more police departments — at an extremely low غير مجاز مي باشدt — are troubling, said Clare Garvie, an associate at the Center on Privacy and Technology at Georgetown University Law Center.

Amazon released Recognition in late 2016, and the sheriff’s office in Washington County, west of Portland, became one of its first law enforcement agency customers.While police might be able to videotape public demonstrations, face recognition is not merely an extension of photography but a biometric measurement — more akin to police walking through a demonstration and demanding identification from everyone there, she said. “Facial recognition in American communities threatens this freedom.”It غير مجاز مي باشدt the sheriff’s office just $400 to load 305,000 booking photos — which are already public records — into the system and $6 a month in fees to continue the service, according to an email obtained by the ACLU under a public records request.“People should be free to walk down the street without being watched by the government,” the groups wrote in a letter to Amazon on Tuesday. We are not putting a camera out on a street corner,” said Deputy Jeff Talbot, a spokesman for the sheriff’s office.The Orlando Police Department said in an email that it “is not using the technology in an investigative capacity or in any public spaces at this time. More than two dozen organizations signed it, including the Electronic Frontier Foundation and Human Rights Watch. “We want our local community to be aware of what we’re doing, how we’re using it to solve crimes — what it is and, just as importantly, what it is not.The privacy advocates’ letter to Amazon followed public records requests from ACLU chapters in California, Oregon and Florida.. Last month, the agency adopted policies governing its use, noting that officers in the field can use real-time face recognition to identify suspects who are unwilling or unable to provide their own ID, or if someone’s life is in danger.”The testing has been limited to eight city-owned cameras and a handful of officers who volunteered to have their images used to see if the technology works, Sgt.It’s not clear how many law enforcement agencies have purchased the tool, called Recognition, since its launch in late 2016 or since its update last fall, when Amazon added capabilities that allow it to identify people in videos and follow their movements almost instantly.“We are not mass-collecting

"We have some tough decisions ahead of us if we want to avoid the worst parts of climate change.The Arctic region has warmed twice as fast as the global average, and Greenland, a resource-rich Danish possession, has become a focal point for climate research -- as well an object of desire for US President Donald Trump, who scrapped a trip to Denmark over its dismissal of his attempts to buy the autonomous territory.The island has three quarters bordering the Arctic ocean and is 85 percent covered in ice -- if this ice sheet were to disappear completely, it would raise the ocean level by seven metres (23 feet).Greenland: Skimming low over the gleaming white glaciers on Greenland&China Automatic Loading And Unloading CNC Cylindrical Grinding39;s coast in a modified 1940s plane, three NASA scientists, led by an Elvis-impersonating oceanographer, waited to drop a probe into the water beneath them."I feel like as a climate scientist I have a responsibility to explain what we're finding to the world," he said.Limited communications and transport links and the island's unpredictable weather all make keeping the mission in the air more complicated, but McCubbin said he was happy to put up with the difficulties."We're looking at probably metres of sea level rise in the next hundred years and that's a huge threat to hundreds of millions of people around the world, so a bit of alarm and OMG is probably warranted," he said.

After each probe hit the water, data started to upload almost immediately onto the small screen on the laptop on the tray table in front of Fenty.5-metre cylindrical probes and watching as the data came in showing the ocean's temperature and salinity.After the flight, Willis, wearing Ray Bans, a leather jacket with the collar turned up and a guitar, gave a performance of his Elvis-inspired "Climate Rock" to diners and visiting journalists in the village's hotel, explaining the difference between the weather and climate.They are part of Oceans Melting Greenland -- or OMG -- a mission that has flown around the vast island for four summers, dropping probes to collect data on how oceans contribute to the rapid melt of Greenland's ice."Dealing with Greenland's remoteness is a unique challenge," McCubbin said on a break between dropping probes, a baseball cap pulled down over his eyes.OMG surveys Greenlandic glaciers in the winter, comparing it with the data they collect about the oceans in the summer over a five-year period, which Willis hopes will allow researchers to better predict sea-level rise."The relevance of this project makes it exciting to work on, given the importance to our society, our children, our children's children," he said.".Dressed in a blue jumpsuit and with thick sideburns that give a hint of his occasional pastime impersonating Elvis, Joshua Willis, 44, is the oceanographer from NASA's Jet Propulsion Laboratory behind the project - and, along with his wife, its name.Today it has more than a dozen satellites in orbit monitoring earth's seas, ice, land and atmosphere, along with missions like OMG, which Willis hopes will provide data to give better predictions of sea-level rise around the globe.

Passing over rocky fjords, dazzling glaciers and icebergs, some dozens of metres (feet) high looming out of the water, Willis and the crew took turns dropping the 1.After two hours in the air along the coast of eastern Greenland, the plane turned and headed back to base at the remote village of Kulusuk, flying low over icebergs and pods of whales in the sea below."The data we're collecting are super valuable because they're allowing us for the very first time to quantitatively relate ocean temperature changes with the melting of the ice sheet," he said.'Tough decisions ahead'Ian Fenty, an investigator with OMG, sat in front # of a laptop and a bank of electronics receiving the signals from the probes.With 20 years' experience flying with the JPL, McCubbin also organises the mission's logistics from the remote airfields it flies out of during the summer.Sucked out into the cold air below, the four-foot cylinder parachuted into the water and after a nervous wait, started transmitting data to the team on the plane.At the rear of the refitted DC3, built in 1942 for the Canadian air force during World War II, project manager Ian McCubbin took his turn by a chute holding the plastic probe, waiting for the order to drop it.Greenland 'a challenge' NASA -- best know for the moon landings and space travel -- started to study the earth's climate in greater depth from the 1970s when its inter-planetary exploration budget was reduced, using its satellites to look at the earth.'Ice cube under a hair dryer' Willis is investigating how warmer layers of water off the coast come into contact with glaciers and how this effects how quickly they melt."A lot of people think of the ice here as melting from the air warming, sort of like an ice cube under a hair dryer, but in fact the oceans are also eating away at the ice's edges," Willis said.For Willis, the song, like his work with OMG, are all part of trying to get his mesغير مجاز مي باشدe about climate change and sea-level rise across
