SAN FRANCISCO (Reuters) — The U.S. government is trying to force Facebook Inc ( FB.O ) to break the encryption in its popular Messenger app so law enforcement may listen to a suspect’s voice conversations in a criminal probe, three people briefed on the case said, resurrecting the issue of whether companies can be compelled to alter their products to enable surveillance.

The previously unreported case in a federal court in California is proceeding under seal, so no filings are publicly available, but the three people told Reuters that Facebook is contesting the U.S. Department of Justice’s demand.

The judge in the Messenger case heard arguments on Tuesday on a government motion to hold Facebook in contempt of court for refusing to carry out the surveillance request, according to the sources, who spoke on condition of anonymity.

“We should not start from steam and railways, or the old technologies—that is already done,” Assefa argues.

That makes sense to academics like Singh — though he also cautions that political forces are often slow to see the bigger picture. There is definitely an opportunity for developing countries, he says. “But any time we have a technological revolution, the political institutions have to catch up.”

A 2017 report (pdf) by the World Wide Web Foundation suggested that Ethiopian “intelligence services are using machine intelligence techniques to break encryption and find patterns in social media posts that can be used to identify dissidents.” And while mobile phone and internet penetration in Ethiopia is comparatively poor—a situation made worst amid widespread anti-government protests, which prompted an internet crackdown in February — the report added that government surveillance and oppression could increase as the use of smartphones expands.

Quantum communication and cryptography are the future of high-security communication. But many challenges lie ahead before a worldwide quantum network can be set up, including propagating the quantum signal over long distances. One of the major challenges is to create memories with the capacity to store quantum information carried by light. Researchers at the University of Geneva (UNIGE), Switzerland, in partnership with CNRS, France, have discovered a new material in which an element, ytterbium, can store and protect the fragile quantum information even while operating at high frequencies. This makes ytterbium an ideal candidate for future quantum networks, where the aim is to propagate the signal over long distances by acting as repeaters. These results are published in the journal Nature Materials.

Quantum cryptography today uses optical fibre over several hundred kilometres and is marked by its high degree of security: it is impossible to copy or intercept information without making it disappear.

However, the fact that it is impossible to copy the signal also prevents scientists from amplifying it to diffuse it over long distances, as is the case with the Wi-Fi network.

What do the Gallic Wars and online shopping have in common? The answer, believe it or not, is cryptography. Cryptography is the cement of the digital world, but it also has a long history that predates the digital era.

Most people do not realize that cryptography is a foundational element to our modern society. At it’s heart cryptography is about access to data, and controlling who can see and use it.

Electrical engineers at Princeton, working with UK manufacturer Element Six, created synthetic diamonds capable of storing and transmitting quantum information, as published in the journal ‘Science’ on Thursday. The research is a major advance for the creation of quantum-encrypted communications.

As the Equifax hack last year showed, there’s a lack of legislation governing what happens to data from a breach. And ultimately, a breach of genetic data is much more serious than most credit breaches. Genetic information is immutable: Vigna points out that it’s possible to change credit card numbers or even addresses, but genetic information cannot be changed. And genetic information is often shared involuntarily. “Even if I don’t use 23andMe, I have cousins who did, so effectively I may be genetically searchable,” says Ram. In one case, an identical twin having her genetic data sequenced created a tricky situation for her sister.

This week, DNA testing service MyHeritage revealed that hackers had breached 92 million of its accounts. Though the hackers only accessed encrypted emails and passwords — so they never reached the actual genetic data — there’s no question that this type of hack will happen more frequently as consumer genetic testing becomes more and more popular. So why would hackers want DNA information specifically? And what are the implications of a big DNA breach?

One simple reason is that hackers might want to sell DNA data back for ransom, says Giovanni Vigna, a professor of computer science at UC Santa Barbara and co-founder of cybersecurity company Lastline. Hackers could threaten to revoke access or post the sensitive information online if not given money; one Indiana hospital paid $55,000 to hackers for this very reason. But there are reasons genetic data specifically could be lucrative. “This data could be sold on the down-low or monetized to insurance companies,” Vigna adds. “You can imagine the consequences: One day, I might apply for a long-term loan and get rejected because deep in the corporate system, there is data that I am very likely to get Alzheimer’s and die before I would repay the loan.”

S cientists have created the UK’s first ever “unhackable” fibre network in anticipation of the dawn of quantum computers, a technology that could render current security systems completely useless and leave critical infrastructure, banking and healthcare networks open to hackers.

The network, constructed by researchers from BT, the University of York and the University of Cambridge over the past two years, is secured by the laws of quantum physics which dictate how light and matter behave at a fundamental level. Using this, it is able to block anyone attempting to crack into the fibre link.

This could be a game changer for the healthcare and financial sector, when it is feared existing encryption…

Developers at major technology companies, outraged by the Snowden disclosures, started pushing back. Some, such as those at WhatsApp, which was bought by Facebook a year after the story broke, implemented their own encryption. Others, such as Yahoo’s Alex Stamos, quit rather than support further eavesdropping. (Stamos is now the head of security at Facebook.)

Five years after historic NSA leaks, whistleblower tells the Guardian he has no regrets.

E xperts are suggesting quantum computing may render blockchain obsolete. As the tech giants such as Google and IBM are showing interest in Quantum computing the danger is evident. According to MIT Technology Review, this type of computing can hack the cryptography hash that universally secures the blockchain and in general the internet. This would suggest quantum computers may complete fraudulent transactions and steal coins. With its exponential power, quantum computers threaten blockchain’s future security.

Blockchain consists of encrypted nodes connected on a chain, which currently makes it almost impossible to hack. The order of entries adheres to the blockchain protocol, which makes it counterfeit-resistant.

To successfully hack a blockchain, you would need to alter both the targeted block and all of the blocks connected. Blockchains are synced throughout a peer-to-peer network. In this type of system, there is no central point of failure for hackers to penetrate. For a hacker to have a chance of penetrating the network, they would need to simultaneously alter at least 51% of the blockchain.
