SAN FRANCISCO, April 22 (Xinhua) -- Apple and Google collect smartphone users' location information as part of their race to build massive databases, The Wall Street Journal reported on Friday after analyzing data and documents.According to the report, security analysts with the newspaper found that Apple's iPhone and smartphones running Google's Android operating system regularly transmit users' locations back to the two companies respectively, which is part of their race to build databases capable of pinpointing people's locations via smartphones.A report by research firm Gartner indicated that the market for location-based services is expected to rise to 8.3 billion U.S. dollars in 2014 from the current 2.9 billion dollars.In the case of Google, a security analyst with The Wall Street Journal said an HTC Android phone collected name, location, signal strength of any nearby Wi-Fi networks, and a unique phone identifier every few seconds and transmitted the data to Google at least several times an hour."All location sharing on Android is opt-in by the user," Google said in a statement to technology blog site All Things Digital, in response to the concern that how Android system uses location information."We provide users with notice and control over the collection, sharing and use of location in order to provide a better mobile experience on Android devices. Any location data that is sent back to Google location servers is anonymous and is not tied or traceable to a specific user," said the statement.Worries on the iPhone tracking issue surfaced on Wednesday after two British researchers announced at a technology conference in California that iPhone has been collecting users' location information and storing the data for extended periods of time.The researchers said starting on June 21 2010, after the release of iOS 4 mobile operating system, iPhones began logging and storing location information in a file, which shows the users' latitude and longitude and is timestamped to the second. They noted the information is not encrypted on the phone or on the iPhone backups made by iTunes and the file is also persistent, transferring itself to a new iOS device when the old one is replaced.They added they had no evidence that the file was being transmitted to Apple.On Thursday, U.S. congressman Edward Markey reacted angrily to the news in a letter to Apple CEO Steve Jobs, which is posted on Markey's official website.Markey asked Jobs to make a response within 15 business days or no later than May 12, saying "Apple needs to safeguard personal location information of its users to ensure that an iPhone doesn't become an iTrack."Apple has made no comment on the issue so far, but a letter it sent to U.S. Congress last July came under spotlight. In the letter, Apple said it collects Wi-Fi and GPS information when the phone is searching for a cellular connection and gathers the data to help build a "database with known location information."

CHENGDU, Jan. 30 (Xinhua) -- Over the crowds of holiday shoppers in China's big stores this Spring Festival lingers an atmosphere of suspicion.With charges of price deception hanging over the big chains of Carrefour and Wal-Mart and local authorities moving to levy fines, many Chinese -- normally averse to be pinching pennies during the Lunar New Year -- are checking their receipts at the tills.The New Year, which falls on Feb. 3 this year, is normally a time of largesse and excess -- all the more reason why many shoppers feel so betrayed.Customers can be seen recording label prices in notebooks or calculating their final bill on their mobile phones as they walk the aisles.At outlets of Carrefour and Wal-Mart in cities such as Beijing, Shanghai and Chengdu, the check out queues have grown as customers doublecheck prices at the tills."I would never have imagined global firms would do this intentionally and I have to be cautious," said a woman surnamed Wang, after shopping at a foreign-owned supermarket in Chengdu, southwest China's Sichuan Province.With three bulging shopping bags, Wang stood next to the check out to calculate the final bill: "We buy a lot for the New Year celebrations, so I have to be more careful."The official weeklong Spring Festival holiday, which starts Wednesday, is China's closest equivalent to the West's Christmas shopping season, with generous gifts of food, tobacco, liquor and other presents for family and friends.According to the Ministry of Commerce, China's retail sales hit 340 billion yuan (49.8 billion U.S. dollars) during the Spring Festival holiday week last year."The deceptive pricing practices of the two foreign-funded supermarket giants were a total scandal," said Wang. "I have to be careful with the prices and the labels.""Cheating by the supermarkets is the same as stealing. I might have suffered losses as I don't normally check receipts," said a Chengdu man surnamed Li.Wal-Mart (China) Investment Co., Ltd. offered a "sincere apology" to affected customers on Thursday. The company has been cooperating with investigations into the cheating. It has also launched inspections of stores nationwide.Chen Bo, spokesperson for Carrefour China, said Sunday that Carrefour sincerely apologized to Chinese customers for inconvenience and losses caused by pricing irregularities.Carrefour would refund customers five times the difference between the price charged and that on the label. The refund policy would be implemented at Carrefour's 182 outlets in China.The issue is continuing to smoulder on the Internet, with websites asking people to write in with "your experiences of price cheating by the Carrefour."A survey by Sohu, one of China's major web portals, had resulted late Sunday in 8,451 of 9,507 respondents saying they "would not go to Carrefour as it is blacklisted for price cheating.""Carrefour will further strengthen price label management and improve service quality to gain the support and confidence of Chinese customers," said Chen Bo.Carrefour had drawn up short and long-term measures to solve the price label issue, including price inspections, improving and upgrading the price label system, and comprehensive staff training."We will have our special control group conduct frequent and wide-ranging internal price inspections," Chen said.The National Development and Reform Commission (NDRC), China's top economic planner and price regulator, said Wednesday that some Carrefour and Wal-Mart stores in China were involved in deceptive pricing practices.The NDRC ordered local pricing authorities to urge stores to correct their wrongdoing, and pay fines five times the illegal income. It also urged authorities to step up price checks ahead of the Spring Festival.

JOHANNESBURG, March 8 (Xinhua) -- In order to combat piracy and to improve maritime safety, South African authorities have begun using a sophisticated navigation satellite system, it was announced on Tuesday.Piracy, especially by Somalis, has been increasing along Africa east coast in recent years. The South African Press Association (SAPA) reported on Tuesday that Karl Otto, head of the South African Maritime Safety Authority (SAMSA) announced the surveillance tool at a conference in Durban.Called Long Range Identification and Tracking (LRIT), the system monitors and tracks vessels in waters south of the equator.Otto said the introduction of the LRIT followed concerns over the safety of seafarers, the safety standards of ships within South African waters.Otto said there were high levels of cargo at risk, such as fuels and oils.He said reasons for installing the system included the number of shipwrecks along the South African coast, and the threat of pollution of the marine environment by ships."It also serves as a mechanism to prevent piracy."Otto said the satellite system has the capacity to identify and track vessels up to 1,000 nautical miles (1,850 km) from the South African coastline as well as South African-flagged vessels anywhere in the world."This is a revolutionary development in the security of our seas," he said.SAMSA was determined to protect South Africa's seafarers, its coastline and the marine environment, Otto said.

BAODING, Hebei, Feb. 3 (Xinhua) -- Chinese President Hu Jintao Thursday called for efforts to promote welfare for senior citizens and vowed to improve the country's health care system to make medical services more affordable.Hu made the call during a three-day inspection tour in Baoding City of northern province of Hebei starting on Tuesday, during which he visited orphans, talked to senior citizens and extended festival greetings to local residents.At a nursing center in Shunping County of Baoding City, Hu offered New Year greetings to senior citizens, orphans and staff of the center.Hu wished the senior citizens good health and a long life, encouraged orphans to study hard, and thanked the staff for the care given to the aged.The Communist Party of China (CPC) and the government will make strenuous efforts to improve the welfare of seniors and make sure their difficulties are solved and they have access to better services, Hu said.When visiting Zhao Helou, a Baoding retiree who has been hospitalized several times and living in difficult circumstances, Hu promised assistance from the Party and the government to help Zhao tide over her problems.The health care and medical insurance system would be improved in the future to tackle people's difficulties in medical care, Hu promised.During his visit to Baoding, Hu also inspected drought conditions at wheat fields, joined villagers during New Year celebrations and extended Spring Festival greetings to passengers, station workers and volunteers.Hu, who is also general secretary of the CPC Central Committee, was briefed on the work of Hebei's provincial committee of the CPC and the provincial government during his tour.

SHANGHAI, Feb. 19 (Xinhua) -- Shanghai and several other Chinese cities have moved to restrict home purchases in a bid to deflate bubbles in the real estate market.The rules, which were revealed by Shanghai's Housing Guarantee and Administration Bureau on Saturday, prohibits new home purchases from locally-registered families who have owned two or more homes and non-local registered families who have owned at least one home.Additionally, non-Shanghai registered families who have no documents certifying they have paid for social security or income tax in the city for one year are banned from buying property.Sales of commercial homes fell 42.4 percent year on year in Shanghai in 2010 as earlier measures to curb the speculative demand in the real estate market took effect.Despite the fall in sales volume, the average price of new commercial homes rose by 7.6 percent to 20,995 yuan (3,200 U.S. dollars) per square meter last year.On the same day, authorities in the eastern city of Nanjing and the northeastern city of Harbin rolled out similar purchase restrictions.On Wednesday, the Beijing municipal government unveiled even tougher measures to prohibit home purchases from non-local registered families who have no proof of social security or income tax payments in the Chinese capital for five straight years.The purchase limits came after the State Council, China's Cabinet, ordered late last month that cities where home prices are skyrocketing must implement strict measures to restrict home purchases over a period of time.The State Council also said that local governments will be responsible for the stable and healthy growth of property markets and are required to publicize, before the end of March, the annual "controlled" price targets for new homes.China has implemented a series of measures since last year, which includes higher down payment and lending rates, and bans on mortgage loans for third homes, to rein in the rapid rise in housing prices.Soaring prices have become a major concern for urban Chinese residents as more homes turn unaffordable. In fact, home prices in some major cities such as Beijing have more than doubled over the past two years.
