A breakthrough algorithm conceals sensitive information so effectively that it is impossible to detect that anything has been hidden, researchers said on Tuesday.
The system — which uses steganography instead of cryptology — is so secure it could allow vulnerable groups such as dissidents to communicate more safely with the outside world, they said.
It could also allow investigative journalists and humanitarian aid workers to communicate easier in some countries.
The algorithm may soon be used widely for digital communications, including social media and private messaging, the team led by the University of Oxford said.
“Our method can be applied to any software that automatically generates content, for instance, probabilistic video filters or meme generators,” said the study's co-lead author Dr Christian Schroeder de Witt.
“This could be very valuable, for instance, for journalists and aid workers in countries where the act of encryption is illegal.
“However, users still need to exercise precaution as any encryption technique may be vulnerable to side-channel attacks such as detecting a steganography app on the user’s phone.”
The algorithm works in steganography, where sensitive information is hidden inside innocuous content, for example hiding a word message inside a digital painting.
Recent advances have helped develop steganography techniques that are perfectly secure, the researchers said.
Previous steganography algorithms would subtly change the distribution of the innocuous content, meaning the changes could also be detected.
To overcome this, the research team used recent advances that allow different sets of data to be sent without the corruption.
Besides being perfectly secure, the new algorithm showed up to 40 per cent higher encoding efficiency than previous steganography methods, they said.
That would allow more information to be concealed within a given amount of data.
The research team has filed a patent for the algorithm, but intend to issue it under a free licence to third parties for non-commercial responsible use, including in the academic and humanitarian fields.

Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.

Pharaoh's curse
British aristocrat Lord Carnarvon, who funded the expedition to find the Tutankhamun tomb, died in a Cairo hotel four months after the crypt was opened.
He had been in poor health for many years after a car crash, and a mosquito bite made worse by a shaving cut led to blood poisoning and pneumonia.
Reports at the time said Lord Carnarvon suffered from “pain as the inflammation affected the nasal passages and eyes”.
Decades later, scientists contended he had died of aspergillosis after inhaling spores of the fungus aspergillus in the tomb, which can lie dormant for months. The fact several others who entered were also found dead withiin a short time led to the myth of the curse.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Some of Darwish's last words
"They see their tomorrows slipping out of their reach. And though it seems to them that everything outside this reality is heaven, yet they do not want to go to that heaven. They stay, because they are afflicted with hope." - Mahmoud Darwish, to attendees of the Palestine Festival of Literature, 2008
His life in brief: Born in a village near Galilee, he lived in exile for most of his life and started writing poetry after high school. He was arrested several times by Israel for what were deemed to be inciteful poems. Most of his work focused on the love and yearning for his homeland, and he was regarded the Palestinian poet of resistance. Over the course of his life, he published more than 30 poetry collections and books of prose, with his work translated into more than 20 languages. Many of his poems were set to music by Arab composers, most significantly Marcel Khalife. Darwish died on August 9, 2008 after undergoing heart surgery in the United States. He was later buried in Ramallah where a shrine was erected in his honour.
