There are records of fingerprints taken many centuries ago. The ancient Babylonians pressed the tips of their fingerprints into clay to record business trade. The Chinese used ink-on-paper finger impressions for business. However, fingerprinting wasn't used as a method for identifying criminals until the 19th century.

In 1858, Sir William Herschel was working as an official of the Hooghly district in Jungipoor, India.In order to reduce fraud(诈骗), he had people living in the district record their fingerprints when signing business documents. A few years later, Scottish doctor Henry Faulds was working in Japan when he discovered fingerprints left by artists on ancient pieces of clay.This finding inspired him to begin investigating fingerprints.In 1880, Faulds wrote to his cousin, the famous naturalist Charles Darwin, and asked for help with developing a fingerprint classification system.Darwin refused, but sent the letter to his cousin, Sir Francis Gallon, who was an eugenicist (优生学家). Gallon began collecting fingerprints and eventually gathered some 8, 000 different samples to analyze. In 1892, he published a book called "Fingerprints", in which he outlined a fingerprint classification system—the first existence.

Around the same time, Juan Vucetich, a police officer in Buenos Aires, Argentina, was developing his own version of a fingerprinting system.In 1892, Vucetich was called in to assist with the investigation of the two boys murdered in Necoche, a village near Buenos Aires. Their mother, Francisca Rojas, accused a neighbour named Velasquez. But when Vucetich compared the fingerprints found at the murder scene to those of both Velasquez and Rojas, they matched Rojas' exactly.She admitted her crime. This was the first time fingerprints had been used in a criminal investigation.Vucetich called his system comparative dactyloscopy(指纹鉴定法). It's still used in many Spanish-speaking countries.

Sir Edward Henry, in charge of the Metropolitan Police of London, soon became interested in using fingerprints to catch criminals. In 1896, he added to Gallon's technique, creating his own classification system, the Henry Classification System. It is the primary method of fingerprint classification throughout most of the world.

It was reported last week that developers could take photos from Apple mobile and Google Android devices without the phone owners knowing that the images were being taken. In Apple’s case, developers can also obtain the location information for each photo.

Senator(参议员) Charles Schumer said in a telephone interview that his office had spoken with officials at both Apple and Google on Monday.

 “We asked them if they could find a way on their own to prevent Apple from having access to private information,” Mr. Schumer said. “They were friendly and open to the idea that this ought to be changed.”

On Sunday, Mr. Schumer said that he planned to send a letter to the Federal Trade Commission asking the agency to investigate Apple and Google after the privacy concerns came to light. Claudia Bourne Farrell, an F.T.C. spokeswoman, said the agency had received the letter but she could not comment further.

“It worries people to think that one’s personal photos, address book, and who knows what else can be obtained and even posted online without permission,” Mr. Schumer wrote in his letter to the F.T.C. “If the technology exists to open the door to this kind of privacy invasion(入侵), then surely technology exists to close it, and that’s exactly what must happen.”

Mr. Schumer said if Apple and Google could not come to an agreement to fix the problem, then he would be forced to take the issue further.

He said other companies had been willing to work with his office to fix issues. “I’m optimistic that we can get this changed without any regulation,” he said. “If it’s not changed, then we’ll turn to the F.T.C., and if that doesn’t work then we’llconsider legislative approach.”

The F.T.C. has warned companies to try to be more vigilant(警醒的) in their efforts to protect consumers when it comes to privacy.

The area south of the Thames at Greenwich has a long history. Throughout time different buildings have been constructed on the same site. The Palace of Placentia, an English Royal Palace built in 1447, no longer exists apart from a few remains under the present buildings.

The grand buildings on the South Bank of the Thames at Greenwich were designed by Sir Christopher Wren, most famous for St. Paul’s Cathedral. The buildings were finally completed in 1745, although some parts started to be used as early as 1705. They’re now part of a university — having served as a naval(海军)hospital and a naval college and the setting for several cinemas.

But the buildings stand on a site which has a much longer history, of which now only a part remains that is below the ground. For nearly two hundred years, from around 1450 to 1650, Greenwich was one of the main royal palaces of England. Some of the most famous English rulers, such as Henry VIII and Elizabeth I, not only lived there, but also were born there.

Henry VIII put an armory(兵工厂)there, and there were also gardens, a great fountain (喷泉) and a mass of buildings. The Palace was also in a strategic location, because at the time either side of Greenwich on the Thames were important Royal Dockyards (船厂).

Eventually, though, the Palace fell into disrepair. In 1664, the King at the time, Charles II, decided to replace it with completely new buildings in a modern style. Only a cellar (地窖) from the former Royal Palace now remains, under one of the new buildings. Its red brick, typical of the 16th century, contrasts (对比) sharply with the white stone above it.
