The passport photographs of the future could turn out to be more than just another pretty picture if a new computer technique developed by Israeli scientists catches on.
Researchers at Ben-Gurion University, in Israel, have invented a way to hide information such as a fingerprint or signature in color images. They believe this could improve passport safety or be used to produce product bar codes(条形码) or designs that cannot be seen.
“The papers can be faxed, scanned(扫描) and reprinted without hidden data disappearing,” New Scientist magazine said last week.
Joseph Rosen and a team of scientists worked out the new instrument by creating a mathematical model.
The model turns a fingerprint or signature into a series of numbers which are used to shape the dots that make up a color picture.
“Each dot can be forced out of the usual place slightly without noticeably changing the final appearance of the image,” the magazine said.
Several images that can be hidden in a single picture are scanned into a computer which does the work.
The hidden images or fingerprints cannot be shown until the picture is scanned again.
The computer rebuilds the fingerprint by measuring the displacement of the dots in the picture.
The magazine said that if he model is used for passport checkpoints the picture can be unscrambled(解码) to show the fingerprint or signature and checked against the person holding the passport.
The researchers are now working on a handheld, and instrument which could make unscrambling the hidden information easier.

Edward Snowden—the fugitive (逃亡者) former U.S.intelligence employee —appears to be stuck in Moscow, unable to leave without a valid American passport, according to interviews Sunday with two men who had sought to aid him: WikiLeaks’ Julian Assange and Ecuadoran President Rafael Correa.
Snowden, 30, arrived at Moscow’s Sheremetyevo International Airport last weekend, after previously taking refuge in Hong Kong. Moscow was only supposed to be a stopover.WikiLeaks, the anti-secrecy organization, had said Snowden was headed on to Ecuador—whose president has been critical of the United States — and that he would seek asylum there.
Now, however, both men said Snowden is unable to leave.
"The United States, by canceling his passport, has left him for the moment trapped in Russia," said Assange, the founder of WikiLeaks, on ABC ' s " This Week With George Stephanopoulos". The United States canceled Snowden' s passport last weekend. Assange criticized the United States, saying: " To take a passport from a young man in a difficult situation like that is a disgusting action."
President Correa spoke to the Associated Press in Puerto Viejo, Ecuador. For now, he told the AP, Snowden was "under the care of the Russian authorities. "
"This is the decision of Russian authorities. He doesn't have a passport. I don't know the Russian laws, I don' t know if he can leave the airport, but I understand that he can' t," Correa said. He said that the case was now out of Ecuador' s hands. "If Snowden arrives at an Ecuadoran Embassy, we' 11 analyze his request for asylum."
Snowden traveled from Hong Kong to Moscow on his U.S.passport. Although the U.S.had already revoked it, Hong Kong authorities said they hadn’t received the official request to cancel the passport before Snowden left.
An official at the Ecuadoran Embassy in London had also issued a letter of safe passage for Snowden. But Snowden apparently did not use it for his trip to Moscow.
And it doesn’t appear that the Ecuadoran government would make a similar gesture again.
On Sunday, Correa told the AP that an Ecuadoran official at that embassy had committed "a serious error" by issuing the first letter without consulting officials back home. Correa said the consul would be punished, although he didn’t specify how.
Correa' s tone seemed to have shifted after a conversation with Vice President Biden on Friday.Where Correa had earlier been aggressive and determined, he now voiced respect for U.S.legal procedures.
1.Edward Snowden is a person who once worked in a federal department ______.
A.to assist the governor of one state
B.to collect information secretly for the US
C.to organize overseas promotion campaign
D.to educate intelligence employees
2.Which of the following word can take the place of the underlined word in Para.2 ?
A.shelter. B.praise. C.position. D.forgiveness.
3.By what means did Edward Snowden leave Hong Kong for Moscow' s Sheremetyevo International Airport?
A.A letter of safe passage from the Ecuadoran Embassy.
B.Permission from Chinese government
C.Invitation of the Russian authorities.
D.An American passport.
4.What can be inferred from the last paragraph?
A.Edward Snowden will live in Moscow forever.
B.Ecuadoran government will provide Edward Snowden protection.
C.Through U.S.legal procedures Edward Snowden has been caught.

Studying Abroad
Are you planning to pursue a course from a foreign university? Well, then you certainly come to the right place. These tips for studying abroad will surely make you feel at home in a new city. Just have a look!
61. _____________________________
Before you leave for your destination country, make sure that you are well aware of its culture, customs and traditions. Every country has its own culture, which may be different from yours. Therefore, if you wish to get adjusted to the local way of living in a short time, you must be aware of what the people eat, how they dress up and also what their sensibilities are. Also, you can catch a few of the commonly used words of the local language there. In this way, not only will you be able to make yourself feel at home in the new city, but also will be spared from experiencing a major culture shock.
62. _____________________________
This is perhaps the most important thing to keep in mind before you set off to foreign shores to study. Make note of all the essential papers you would need before and during your stay abroad, especially the passport and the visa. It is recommended that you make copies of both, your passport and visa, in case you might be required to get a new one during the course of your stay there. Also, at least one other member of your family should have a passport made so that you can have somebody by your side if you fall sick or in case of other emergencies. Also, it is a good idea to carry a few copies of your photo, in case you need to use one. Another thing that’s necessary is to get a health insurance to cover the expenses of a medical emergency abroad.
63. ____________________________
When you decide to pursue a course abroad, it is extremely important that you should research well. Don’t just follow advertisements and choose one blindly. Instead, talk to people who have completed their studies from that country or who are planning to move to the same country. This way you’ll get some reliable information.
64. _____________________________
Not only will it make it easier for you to face personal interviews but also to interact with the local people and follow students. The more you speak to people, the more you’ll end up making friends quickly. What a way to drive the blues away!
65. _____________________________
Get the details of the Embassy(大使馆) in the city you’re moving to, including the phone number and register yourself and your family members with the Embassy. This way you’ll know whom to reach out to in case you are in trouble in a foreign location.
