WhatsApp is more private now: 10 things you need to know

April 6, 2016

Apr 6: WhatsApp last night turned on the encryption within the app. That has created a lot of buzz. But why and how exactly it affects WhatsApp users?

encryptedWell, sit tight and let us explain it all to you in 10 quick points:

1- Starting Tuesday night, all WhatsApp communication is encrypted. This means, now when you chat with your friends, cyber criminals or even government sleuths will not be able to capture the data and read your chats, even if they are stealing all your Wi-Fi traffic. Although, they can still steal, confiscate or snatch your phone and read all your chats.

2- The WhatsApp encryption is end-to-end. This means the keys to encrypt the chats will be stored only with users. Even WhatsApp won't have any key, so the government can't demand such keys from the company that runs the chat app.

Here is how WhatsApp co-founders explained it: "The idea is simple: when you send a message, the only person who can read it is the person or group chat that you send that message to. No one can see inside that message. Not cybercriminals. Not hackers. Not oppressive regimes. Not even us. End-to-end encryption helps make communication via WhatsApp private - sort of like a face-to-face conversation."

3- For added security, you can even authenticate chats on WhatsApp. This, according to WhatsApp, will be done between users through a QR Code or a 60-digit number.

4- The WhatsApp encryption is 256-bit strong. Theoretically, it is impossible to crack it by brute force method. Although, there could be implementation loopholes that government agencies like the NSA in the US can exploit.

5- If you want to use WhatsApp encryption, all you need to do is download the latest version of the app. It is enabled by default.

6- Now everything is encrypted on WhatsApp. Text, your selfies, the funny videos, even the PJs in school group are encrypted. Isn't it wonderful? Cyber criminals won't even be able to sniff out all the "photoshopped" forwards that you receive in your WhatsApp group.

7- The encryption is not expected to have any significant effect on the user experience. The service will, possibly, continue to be fast and free.

8- The big deal about the WhatsApp encryption is that suddenly over a billion people on earth have access to incredibly secure and private communication. This is unprecedented and makes WhatsApp move wonderful and scary at the same time.

9- According to WhatsApp, its latest feature is built using "the Signal Protocol, designed by Open Whisper Systems." The company says that this protocol is specifically developed to keep third-parties like cyber criminals and government officials away from private communications.

10- At a time when the concept of privacy is almost gone, WhatsApp encryption changes the rule of the game. It will probably force other technology companies to offer encryption by default. As WhatsApp co-founders said, "we expect that (WhatsApp-like encryption) will ultimately represent the future of personal communication".

Big Lie
I request my Muslim brothers stop being emotional on whatsapp/ facebook. There is nothing called freedom of speech on social networking sites. Most of Investigative agencies working in our country are only behind Muslims.

Bengaluru, Jun 10: Internet connectivity, provided under the central government's BharatNet initiative, will be improved in rural areas of Karnataka in the next two to three months, said Deputy Chief Minister CN Ashwath Narayan.

After video conferencing with heads of different agencies and officials, on improving the quality of internet in rural areas, Ashwath Narayan said, "I reviewed the progress of the BharatNet implementation and the steps to be taken to improve the quality of internet connectivity in the next two to three months."

"We also discussed the possibility of giving the implementation of BharatNet to a different agency. We will seek permission from the central government and continue the project. We will ease communication with rural people by ensuring quality and high-speed internet to all Gram Panchayats," he added.

When BSNL officials and other agency representatives who attended the video conference shared their problems, the Deputy Chief Minister assured to solve them through proper coordination.

"Through BharatNet, several government schemes are being implemented in rural areas. Civic service centres are issuing birth and death certificates, Aadhaar cards and social security pensions among others. Of the total 6,000 Gram Panchayats in the state, 4,000 have high-speed internet connectivity, and the remaining will be provided with better internet connectivity through a new agency,'' said Ashwath Narayan.

Additional Secretary (e-governance) Rajeev Chawla, Additional Chief Secretary (IT-BT) EV Ramana Reddy, Principal Secretary (RDPR) Uma Mahadevan, Director (IT) Meena Nagaraj, Collegiate Education Director Pradeep and other senior officials were present in the meeting.

Bengaluru, Feb 12: Mohammed Nalapad, the rogue son of Karnataka Congress leader NA Harris, who is out on bail in a 2018 case of him bashing up a man at a pub, has now rammed his luxury car into vehicles, injuring four people on Bengaluru road.

The incident took place on Sunday on the Ballari Road where Nalapad was rash driving his car. The car hit a biker and an autorickshaw, injuring four people. He immediately got off his car and fled riding a friend's car.

The biker has suffered a fracture in his leg and is undergoing treatment at a hospital.

According to police, soon after the accident a man appeared before police to claim responsibility for the accident.

Ravikante Gowde, Joint Commissioner of Police said, "A man named Balakrishna came to surrender as the one who was driving the car. Investigation has, however, showed that it was Nalapad who was driving when he met with the accident. The investigating officer has issued him a notice to appear before the police."

BJP spokesperson S Prakash has said, "A case under the Goonda Act should be filed against Nalapad and the court should take cognisance of this and cancel his bail. The father has no control over son. He is a serial offender who is harming the public on a repeated basis."

Nalapad was earlier arrested in 2018 in the Bengaluru pub incident in which he and his associate bashed up the son of a prominent businessman in the city. Nalapad Harris is out on bail after remaining in judicial custody for three months in the case of attempt to murder after the 2018 midnight brawl.

Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.
