ARM chip promises cheaper phones

UK chip designer ARM has unveiled a new processor, which should allow manufacturers to make cheaper smartphones.

The company hopes the Cortex A7 will enable a mobile computing revolution in developing countries where current technologies are often unaffordable.

Consumers in developed countries should also see a benefit.

The ultra-efficient chip can be paired with more powerful processors in a "hybrid" model to reduce power use.

ARM's designs are used in approximately 95% of the world's smartphones.

A range of big name manufacturers have already signed-up to use the A7 processor along with the company's "big.LITTLE" architecture.

Samsung, LG, NVidia and Texas Instruments were among those to throw their weight behind the technology.

Apple is also known to make use of ARM-designed chips in its mobile devices, although it has historically been reluctant to say so publicly.

Smaller and cheaper

Used as the sole processor in a smartphone, the A7 is said to offer comparable power to current chips at a fraction of the price, while consuming much less battery power.

Its silicon core is only one-fifth of the size of existing technologies, allowing a reduced production price, according to ARM chief executive Warren East.

"You typically make chips on a silicon wafer and it costs roughly the same amount of money for each wafer. If you can get 2,000 devices on a wafer or 1,000 devices on a wafer it makes a huge difference to the cost per device," he told BBC News.

"We can see the developed world moving on and mobile being the nexus for all sort of consumer electronics. In the Bric countries (Brazil, Russia, India and China) we are seeing catch-up.

"As we look forward these smartphones are going to be totally ubiquitous and in the much less developed areas, such as Africa, you will see smartphones becoming tools that people use to make their lives easier."

Mr East said that the trend would happen regardless of intervention, but cheaper devices would greatly accelerate that, enabling smartphones to be produced for under $100 (�60) by 2013 or 2014.

Little and large

In countries where price is less of an issue, the Cortex A7 may be combined with high end mobile processors to offer a powerful, yet energy-efficient package, ARM said.

For less demanding tasks such as checking in the background for email and social networking updates, the A7 processor would handle the work.

Using a technology known as big.LITTLE, the phone would instantly switch over to chips such as the Cortex-A15 when more horsepower was needed.

"It's not just trying to solve the issue of doing yet another CPU with higher performance," said Avner Goren, general manager of Omap strategy at Texas Instruments, one of ARM's clients.

"I don't need massive processing all the time, I need it only some of the time, and for the rest I can use A7. This allows me now to continue the path to more and more powerful devices but without sacrificing battery life."

Although ARM currently enjoys a dominant position in the smartphone and tablet markets, the Cambridge-based firm is facing the prospect of stiff competition from Intel, which has recently entered the mobile processor business.

Its Sandy Bridge and forthcoming Ivy Bridge processors are also aimed at the smartphone and tablet markets.

Researchers warn of new Stuxnet

Researchers have found evidence that the Stuxnet worm, which alarmed governments around the world, could be about to regenerate.

Stuxnet was a highly complex piece of malware created to spy on and disrupt Iran's nuclear programme.

No-one has identified the worm authors but the finger of suspicion fell on the Israeli and US governments.

The new threat, Duqu is, according to those who discovered it, "a precursor to a future Stuxnet-like attack".

Its discovery was made public by security firm Symantec, which in turn was alerted to the threat by one of its customers.

Symantec looked at samples of the threat gathered from computer systems located in Europe.

Initial analysis of the worm found that parts of Duqu are nearly identical to Stuxnet and suggested that it was written by either the same authors or those with access to the Stuxnet source code.

"Unlike Stuxnet, Duqu does not contain any code related to industrial control systems and does not self-replicate," Symantec said in its blog.

"The threat was highly targeted towards a limited number of organisations for their specific assets."

In other words, Duqu is not designed to attack industrial systems, such as Iran's nuclear production facilities, as was the case with Stuxnet, but rather to gather intelligence for a future attack.

The code has, according to Symantec, been found in a "limited number of organisations, including those involved in the manufacturing of industrial control systems".

Symantec's chief technology officer Greg Day told the BBC that the code was highly sophisticated.

"This isn't some hobbyist, it is using bleeding-edge techniques and that generally means it has been created by someone with a specific purpose in mind," he said.

Whether that is state-sponsored and politically motivated is not clear at this stage though.

"If it is the Stuxnet author it could be that they have the same goal as before. But if code has been given to someone else they may have a different motive," Mr Day said.

He added that there was "more than one variant" of Duqu.

"It looks as if they are tweaking and fine-tuning it along the way," he said.

The worm also removes itself from infected computers after 36 days, suggesting that it is designed to remain more hidden than its predecessor.

The code used a "jigsaw" of components including a stolen Symantec digital certificate, said Mr Day.

"We provide digital certificates to validate identity and this certificate was stolen from a customer in Taiwan and reused," said Mr Day.

The certificate in question has since been revoked by Symantec.

Cyber warfare

The discovery of the Stuxnet worm was a game-changer in the world of malware and forced governments around the world to beef up the security behind critical systems such as power and water.

It brought the issues of cyber warfare, government-to-government espionage and cyber terrorism firmly to the top of the agenda.

Experts who have studied the Stuxnet worm say that it was configured to damage motors used in uranium-enrichment centrifuges by sending them spinning out of control.

Iran later admitted that some of its centrifuges had been sabotaged although it downplayed the significance of Stuxnet in that.

Stuxnet is not the only example of malware designed to cause government-level disruption.

In 2009 China was accused of spying on Google and in the summer US defence firm Lockheed Martin was victim of a "significant cyber-attack" although it said that none of its programmes had been compromised.

This week the US Department for Homeland Security warned that politically-motivated hackers such as the Anonymous co-operative could begin to target industrial control systems.

Android shows Ice Cream Sandwich

Google has unveiled the latest version of its industry-leading Android smartphone software.

Ice Cream Sandwich adds a range of new features and a redesigned interface.

The system was launched in partnership with Samsung, whose Galaxy Nexus handset will be the first to use it.

Android's main rival, Apple, released an update to its iOS software last week, although many owners were unable to download it immediately due to overwhelming demand.

Ice Cream Sandwich - also known as Android 4.0 - follows the tradition of naming versions after cakes, confectionary or frozen desserts.

Previous releases have been codenamed Cupcake, Donut, Eclair, Froyo and Gingerbread.

Design changes for Android 4.0 include:

  • Replacing physical buttons on devices with equivalent on-screen icons.
  • New lock screen features - the ability to access camera and notifications.
  • Ability to group apps and shortcuts by dragging icons onto each other.
  • Redesigned multi-tasking screen. Applications are represented by scrollable tiles.

Other software changes include:

  • Face recognition unlocking. Rather than entering a pattern code as in previous versions, users can opt to look into their camera.
  • Enhanced email capability - support for nested subfolders
  • Android Beam - users can swap web content or links to apps by touching their phones together.
  • Enhanced voice input featuring a continuously open microphone - meaning phones listen out for instructions.
Phoney war

Android - which is owned by Google - and Apple are continually leap-frogging each other in terms of design and functions, as both compete for customers in the fast-growing global smartphone market.

According to figures published by Canalsys in August, Android handsets accounted for 48% of smartphones shipped to retailers, compared to 19% for Apple devices. However, many more Android models are available, from manufacturers such as HTC, Motorola, Samsung and Sony Ericsson.

The fierce competition has, on occasion, brought the two sides into direct conflict.

Apple and Samsung are currently engaged in a number of legal battles, around the world, some of which involve claims of patent infringement and "copying" of device look and feel.

To date, Apple has obtained injunctions on Samsung Galaxy tablets being sold in Germany and Australia, with a ban on some smartphones due to come into effect in the Netherlands.

Apple full year profits rise 85%

The world's biggest technology company Apple has reported full year results, showing net profit for the year to 25 September at $25.9bn (�16.5bn), up 85% from the previous year.

Even that was not enough to satisfy Wall Street, with the shares falling nearly 5% in after-hours trading.

There was some disappointment with the fourth quarter of the year, when no major new products were released.

It is the first set of results since the death of co-founder Steve Jobs.

In the fourth quarter of the year, Apple sold 17.1 million iPhones, which was a 21% increase on the same period last year, and 11.1 million iPads, which was a 166% increase.

But analysts had been expecting iPhone sales of 20 million in the quarter.

Apple said sales were hurt in September by customers waiting for the new version, the iPhone 4S, which was released on 14 October.

It sold four million of the new models in the first three days after launch.

"The numbers came in weak. They need to set records every time they report to keep up the momentum," said Colin Gillis, analyst at BGC Partners.

Apple sold 4.9 million Mac computers in the quarter - up 27% over the same period last year.

"The numbers are actually quite good. The reason why the stock is off - I think some of the analysts got carried away," said Shaw Wu, analyst at Sterne Agee.

Warning over web security attack

A key web security system is no better defended now than when hackers undermined it earlier this year.

So said Taher Elgamal, creator of the SSL (Secure Socket Layer) technology that is used to keep many different types of web transaction safe.

SSL came under attack in September when hackers stole credentials that let them pose as almost any web firm.

The stolen credentials were used to eavesdrop on the Gmail accounts of about 300,000 people.

Big target

The credentials, known as certificates, were stolen from Dutch security firm DigiNotar. The attack is believed to have been carried out by the same hackers who stole certificates from Comodo in March 2011.

In both cases, the attackers used their fake credentials to get at the web communications of people in Iran. Experts believe the hacks were carried out by the Iranian government to spy on the use of social media to organise protests by citizens.

A similar attack could be used by cyber thieves who wanted to pose as a bank or web shop to steal cash and credit card information from users.

Despite the two incidents and a claim by the hackers that they had access to four other firms that issue SSL certificates, little has been done to defend against these sorts of attacks, said Dr Elgamal, who is now chief technology officer at Axway.

"It could happen again," he said. "There's no back-up plan, which is generally a bad security model."

Dr Elgamal first developed SSL while working at Netscape and its usefulness led to it being adopted as a standard web technology known as Transport Layer Security (TLS) by the Internet Engineering Task Force.

The system guarantees the identity of a website via certificates that are issued by trusted authorities. It is used millions of times every day to re-assure people that they are connecting to the site they think they are.

The problem of what to do when certificate issuers were compromised never came up when the original work was being done on SSL/TLS, said Dr Elgamal.

"Nobody asked the question of what to do if a certificate authority turns out to be bad," he said.

The problem, he said, was not so much with the technology as it was with the firms issuing the certificates.

"There's way too many of them," he said.

However, said Dr Elgamal, TLS was not a static technology and in fact was regularly updated to tackle some of the shortcomings found by good and bad hackers

"It's a big target," he said. "Of course we could design a new one but I don't see what the point of that is as it would just become the next big target."

He pointed to updates to TLS which, if widely implemented by browser makers, could defend it from another attack.

"The fact that TLS has stood the test of time and there's been problems and the community has worked to fix them tells me it's a reasonable technology," he said.

Machine vision spots rotten fruit

A machine that uses artificial vision and UV rays to scan through citrus fruits and get rid of rotten ones has been developed in Spain.

Usually the inspection is done manually in dark rooms, also using UV light.

But this type of light can harm workers' eyes and skin, so they must wear protective clothing and goggles.

The team from the Valencian Institute of Agrarian Research said that their technology could eliminate these risks.

The researchers describe the study in the journal Food and bioprocess technology.

Health risks

Detecting rotten citrus fruit is tricky, as interior decay is not visible to the naked eye.

That is why traditionally, workers use ultraviolet light - and when the essential oils of the decayed citrus rind react with UV rays, the fruits emit fluorescence.

But although there is usually a good chance that the oranges and mandarins that present spots of fluorescence turn out to be rotten, it is not always the case.

Florescence can be produced by defects other than decay, and thus workers often need to examine the fruit manually as well.

They must wear gloves and special goggles, and should not stay in the dark room too long.

"The biological effect of UV rays is very bad for the health," said Gregory Varennes of Roda Iberica, the company responsible for introducing the technology into the market.

"According to the tolerable radiation limits of the UV light lamps, operators must not remain in the dark room for more than one hour - but often they stay in there for longer periods.

And this labour also represents a considerable cost for the company, added Mr Varennes.

Early detection

So to avoid workers' UV exposure, Professor Jose Blasco of the Valencian Institute of Agrarian Research and his colleagues decided to let a machine do the job.

"Our system captures the images of the fruits inside an inspection chamber illuminated only with black light," he said.

"If the fruit is infected, it will show a spot of fluorescence, which is like a small right circle in the middle of the dark.

"The machine then uses image analysis techniques that are combined with UV to confirm the detection."

He added that fruit decay was one of the main causes of lost profits in the industry - meaning that detecting infected fruits as soon as possible and removing them from the rest of the pack was crucial.

The team has also developed another, similar mechanism that classifies citrus fruits on the production line according to their quality, colouring and the type of damage that the skin presents - at a speed of 15 to 20 pieces of fruit per second.

Thus, first class fruits that are destined for more demanding markets are separated from second class fruits that are perfectly edible despite having some small defects such as visible scratches.

HTC loses Apple patent case in US

Taiwanese smartphone maker HTC has been dealt a big blow in its legal battle with Apple involving patent infringement claims.

The US International Trade Commission (ITC) has ruled that Apple did not violate patents as claimed by HTC in a complaint lodged last year.

HTC had asked the court to ban imports of several Apple products in to the US citing patent infringements.

HTC's shares fell as much as 6% after the ruling.

The case involved four patents held by HTC related to protecting data, storing contact information and managing the phone's power supply.

'Confident'

The judgement is another setback for HTC which is involved in a long and bitter battle with Apple.

In July this year, the Taiwanese phonemaker was found to have infringed two iPhone patents in a case brought by Apple at the ITC.

However, HTC said that despite the judgement, it was sticking to its claims.

"This is only one step of many in these legal proceedings. We are confident we have a strong case for the ITC appeals process and are fully prepared to protect our intellectual property," said Grace Lei, HTC's general counsel.

"We look forward to resolving this case, so we can continue creating the most innovative mobile experiences for consumers."

A full commission of the ITC is expected to decide in February, whether to uphold or reject the judge's decision.

Samsung seeks iPhone4S sales ban

Samsung electronics has raised the stakes in its current legal battle with Apple by seeking a ban on sales of iPhone4S in Australia and Japan.

This follows similar pleas by the Korean manufacturer in France and Italy claiming patent infringement by Apple.

The move comes after a court in Australia temporarily banned the sales of Samsung's Galaxy Tab 10.1.

The two companies have been involved in a bitter legal battle involving smartphones and tablet PCs.

"Apple has continued to violate our patent rights and free ride on our technology," Samsung said in a statement. "We will no longer stand idly by and will steadfastly protect our intellectual property."

Losing ground?

While there have been claims and counter claims from both sides, Apple seems to be gaining the initial edge in the legal battle between the two.

Last week, a judge in the US ruled that Samsung's tablets infringed patents owned by Apple. However, she said that Apple needed to prove the validity of those patents in order to win an injunction preventing the sale of Samsung's Galaxy Tab.

This followed a ban by an Australia court on the sale of Samsung's Galaxy tab 10.1 in the country.

Samsung said it had filed an appeal against the Australian court's decision.

Apple has also scored a victory against its rival in Germany, Europe's biggest economy, banning the sale of the Galaxy Tab 10.1.

Meanwhile Samsung's plea for a sales ban against some of Apple products was rejected by a Dutch court last Friday.

EU billions for broadband plan

The European Commission is set to propose investing almost €9.2bn (�8bn) in a massive rollout of super-fast broadband infrastructure and services across the European Union.

The plan is partly aimed at stimulating further investment in rural broadband.

It is hoped the initiative will also help to create a single market for digital public services.

The Commission has already set targets for improving the speed of home internet connections across the region.

It aims to get all European households on at least 30 megabits per second (Mbps) by 2020, with half the population enjoying more than 100Mbps, so as to make the continent more competitive and productive.

Economic need

The BBC understands that the EU's executive body will propose the funding, which would be invested between 2014 and 2020, on Wednesday.

The plan would have to be approved by the European Parliament and the EU's Council of Ministers if it were to become reality.

"Europe needs these fast broadband networks to allow its economy to become more competitive in the future, and so create more jobs and prosperity," EU sources said.

"This money would stimulate much greater investment of private and other public money. Each euro [invested by the Commission] would give rise to a further six to 15 euros more."

At least €7bn of the investment would go to building high-speed broadband networks, with the funding mostly in the form of debt instruments and equity.

The hope is that giving infrastructure projects credibility in this way would encourage the private sector, as well as local and national governments, to invest at least a further €50bn in the rollout.

The remainder of the Commission's funding would be parcelled out in grants for projects that could help create a single European market for broadband-based services such as e-health, cybersecurity and intelligent energy networks.

The money would come from a new fund called the Connecting Europe Facility (CEF). This proposed fund would also be used for new transport and energy projects, with the Commission and the European Investment Bank absorbing risk and boosting the projects' credit ratings.

Part of the plan is for the CEF to pressure established telecommunications companies into investing more in their own networks, as they would not be the only ones able to bid for funding.

New players such as water, sewage and electricity utility companies would also be encouraged to enter the broadband game with CEF backing, as would construction firms, cooperatives and public authorities.

Rural boost

A particular objective is to get more money invested in rural broadband. Left to their own devices, telecoms companies often invest less in such areas because they are not as profitable as more densely-populated towns and cities.

While the Commission's digital agenda is largely about getting citizens on fast connections, it also contains plans to make electronic public services available equally across the continent.

Under the proposals to be unveiled on Wednesday, grants could go to cross-border e-health and electronic procurement services, smart energy networks and coordinated efforts to take down online child pornography.

Other examples of projects that would meet the Commission's criteria include pan-EU electronic identity schemes, systems that would encourage access to European culture, and multilingual public information services.

The Commission also hopes its plan would immediately create hundreds of thousands of jobs in the construction and telecoms equipment industries, as efforts to install fibre optic cable networks increase with the additional backing.

European funding has already found its way to several fast broadband projects in the UK. Last year the European Regional Development Fund provided �53.5m to aid BT's next-generation broadband scheme in Cornwall, while �18.5m went to the development of Northern Ireland's broadband infrastructure, also in collaboration with BT.

Apple hits Samsung in court again

Samsung's tablets infringe patents owned by Apple, a US judge has ruled.

However, she warned that Apple needs to prove the validity of those patents if it is to win an injunction preventing the sale of Samsung's Galaxy Tab.

The decision is the latest in a dispute which spans 20 cases in 10 countries, some of which have lead to Samsung products being taken off the shelves.

Apple claims that the Galaxy range "slavishly" copies its massively-selling iPad and iPhone.

The Californian company has sought to ban the sale of the Galaxy S 4G smart phone and Galaxy Tab 10.1 tablet in the US.

A similar ruling in an Australian court led to a temporary sales ban on the tablet in that country.

US mobile networks have opposed Apple's request, saying it could affect sales of the products in the run up to Christmas.

California District Judge Lucy Koh ruled that while patents have been infringed, Apple must now show that its claim on those inventions is valid.

The disputed patents include three covering design - including the exterior look of the device - and a 'list scrolling patent' which relates to how users view documents.

Samsung argued that Apple's claims are invalid due to previously registered patents relating to design elements and functionality.

The company's attorney, Kathleen Sullivan, said her client "clearly raised substantial questions" and that the injunction bid should therefore be rejected.

"Start Quote

It's no coincidence that Samsung's latest products look a lot like the iPhone and iPad"

End Quote Apple spokeswoman

But Apple argue that its own product's design is far superior to those which came before the iPad and iPhone, and so therefore its patents should not be invalidated.

At one point in the hearing the judge held both Samsung and Apple products up on the air and challenged the defence to whether they could identify which device was which.

Samsung attorney Ms Sullivan, who was roughly 10 feet away, responded: "Not as this distance your honour."

Another lawyer for Samsung correctly distinguished the two.

A spokesman for the South Korean company described Apple's claims as "groundless".

Apple spokeswoman Kristen Huget said: "It's no coincidence that Samsung's latest products look a lot like the iPhone and iPad.

"This kind of blatant copying is wrong, and we need to protect Apple's intellectual property when companies steal our ideas."

Both companies have been locked in patent disputes since April, with each accusing the other of infringing various patents.
