The information arms race can’t be won, but we have to keep fighting

By Cailin O’Connor -Arms races happen when two sides of a conflict escalate in a series of ever-changing moves intended to outwit the opponent. In biology, a classic example comes from cheetahs and gazelles. Over time, these species have evolved for speed, each responding to the other’s adaptations.

One hallmark of an arms race is that, at the end, the participants are often just where they started. Sometimes, the cheetah catches its prey, and sometimes the gazelle escapes. Neither wins the race because, as one gets better, so does its opponent. And, along the way, each side expends a great deal of effort. Still, at any point, the only thing that makes sense is to keep escalating.

Arms races happen in the human world too. The term arms race, of course, comes from countries at war who literally amass ever-more sophisticated and powerful weapons. But some human arms races are more subtle.

As detailed in the Mueller report – but widely known before – in the lead-up to the 2016 presidential election in the United States, the Russian government (via a group called the Internet Research Agency) engaged in large-scale efforts to influence voters, and to polarize the US public. In the wake of this campaign, social-media sites and research groups have scrambled to protect the US public from misinformation on social media.

What is important to recognize about such a situation is that whatever tactics are working now won’t work for long. The other side will adapt. In particular, we cannot expect to be able to put a set of detection algorithms in place and be done with it. Whatever efforts social-media sites make to root out pernicious actors will regularly become obsolete.

The same is true for our individual attempts to identify and avoid misinformation. Since the 2016 US election, ‘fake news’ has been widely discussed and analyzed. And many social-media users have become more savvy about identifying sites mimicking traditional news sources. But the same users might not be as savvy, for example, about sleek conspiracy theory videos going viral on YouTube, or about deep fakes – expertly altered images and videos.

What makes this problem particularly thorny is that internet media changes at dizzying speed. more>

A.I. is only human
By Jeff Cockrell – If you applied for a mortgage, would you be comfortable with a computer using a collection of data about you to assess how likely you are to default on the loan?

If you applied for a job, would you be comfortable with the company’s human-resources department running your information through software that will determine how likely it is that you will, say, steal from the company, or leave the job within two years?

If you were arrested for a crime, would you be comfortable with the court plugging your personal data into an algorithm-based tool, which will then advise your judge on whether you should await trial in jail or at home? If you were convicted, would you be comfortable with the same tool weighing in on your sentencing?

Much of the hand-wringing about advances in artificial intelligence has been concerned with AI’s effects on the labor market. “AI will gradually invade almost all employment sectors, requiring a shift away from human labor that computers are able to take over,” reads a report of the 2015 study panel of Stanford’s One Hundred Year Study on Artificial Intelligence. But whether AI ultimately creates massive unemployment or inspires new, as-yet-unknown professional fields, its perils and promises extend beyond the job market. By replacing human decision-making with automated processes, we can make businesses and public institutions more effective and efficient—or further entrench systemic biases, institutionalize discrimination, and exacerbate inequalities.

It’s an axiom of computing that results are dependent on inputs: garbage in, garbage out.

What if companies’ machine-learning projects come up with analyses that, while logical and algorithmically based, are premised on faulty assumptions or mismeasured data?

What if these analyses lead to bad or ethically questionable decisions—either among business leaders or among policy makers and public authorities? more>

Latest trends in optical networks- straight from NGON & DCI World
By Helen Xenos – “If you are not sitting at the edge of your seat, you are taking up too much space.”

I heard this quote from a friend recently and thought it was interestingly appropriate in describing the optical networking industry these days. No one has time to sit back. Technology is evolving at an incredibly fast pace, new developments are occurring at a regular cadence, and network providers are regularly evaluating different architecture approaches for evolving their networks.

In attending the 21st Annual NGON & DCI World event in beautiful Nice last week, I had an opportunity to get a pulse on the latest topics and trends that are driving change in the optical networking landscape.

A popular topic at all optical events – and NGON was no exception – is the discussion of the next technology breakthrough that will bring new levels of capacity scale and cost reduction to transport networks.

If we look at coherent optical shipments, capacity and average selling price data over the past decade, what is the principal way that network providers have been able to keep up with exponentially increasing bandwidth demands while maintaining transport costs relatively flat? Through coherent technology innovations that have enabled higher throughput at less cost.

So, how will we get to the next level of cost reduction?

The consistent response to this question in multiple sessions at NGON was higher baud, which means coherent optical solutions that have a higher symbol rate and can process more data per second, resulting in more fiber capacity with less equipment. more>

AI, quantum technologies and new cyber threats – are we prepared?
ITU News – Quantum computing is on the horizon. The emerging computing architecture renders possible a form of ‘super parallel processing’ based on quantum physics that can rapidly solve problems beyond the scope of what a classical computer can achieve.

Quantum computing is fast advancing, with governments investing billions and blue-chip technology heavyweights prioritizing the technology.

With far-reaching implications for data security, advances in quantum computing risk unraveling data encryption, with far-reaching implications for security.

What this means is that quantum computers will be incredibly effective at hacking into encrypted data – rendering sensitive data and critical infrastructures, as well as Internet of Things and 5G networks, vulnerable to attack.

Although the technology is not yet commercially deployed, the security threats are already here.

The ‘download now, decrypt later’ attack vector already sees actors downloading existing encrypted data, to be cracked open once the technology arrives.

“Now, it’s not a matter of if it will happen,” said Mark Jackson of Cambridge Quantum Computing during a panel discussion on AI, quantum technologies and new cyber threats at the recent AI for Good Global Summit. more>
