Recognising your own handwriting rather than remembering a password could be used for online identification, new research shows.Your handwriting could be the best form of online security, say the developers of a new system that may one day replace difficult-to-remember passwords and PIN codes. With the new authentication program Dynahand, users just need to be able to recognise their own writing."I know it's my handwriting, but I don’t know how I know. I can't explain to somebody else how I do it," says Dr. Karen Renaud, a computer scientist and lecturer at the UK's University of Glasgow. She argues that's what makes the system more secure than coming up with a standard password, which is repeated over and over at different sites, can be shared with a friend, or stolen by an adversary.The system works using handwritten numbers instead of letters because although others may be able to recognise your penned words, they're not so good at distinguishing your handwritten numerals.In the laboratory test, Renaud asked 11 people to write the numbers 0 to 9 several times. She asked other volunteers to provide samples of their numerals, too, but these were eventually used to distract the study participants. She then scanned the numbers into a computer and used a software program, or algorithm, written by colleague Elin Olsen, to analyse the characteristics of the handwriting, such as height and width of strokes. The algorithm also kept track of which numerals belonged to which person and whose handwriting was more similar or distinct.At authentication, the program showed the participant a series of five-number handwritten PINs, each one randomly generated from the handwritten numerals. The number was not important and the user did not have to remember it. Instead the participant clicked on the PIN written in his or her handwriting. If they got it right, the program showed them another set of PINs. They then clicked again on the correct image.The program shows the user four sets of PINs, which takes about 28 seconds to complete, but ensures a higher level of security than just showing one set. And as with other PIN-password system, three wrong attempts and you're locked out.In the test, 10 of the 11 people recognised their own handwriting consistently. Although most of the people got it right, 11 participants is a low number to demonstrate the effectiveness of the technology, says Steve Furnell, professor of information systems security at the UK's University of Plymouth. "But the idea itself is very interesting," he says.In addition, although Renaud does not believe that this password method is robust enough to be used for sites with high-level security, such as online banking or e-commerce, it could work as a second layer on such sites, e.g., when you are changing an address or credit card information. /200812/58752池州治疗生殖器疱疹男性医院Serena的汉普敦发髻S难得会折腾自己的头发,总是保持着招牌式的长波浪,因而这款特别的造型格外引人注目。如果你自己想要照着这个样子山寨个的话,也可以尝试着将头发编成小辫子,或者在发髻外面接驳上头发,从而增加细节处的精致。Serena rarely ventures from her long, slightly wavy trademark, so this special style stands out. It's possible to fake a braid like that or pick up an extension to wrap in for added detail to an updo. /200904/67121池州石台县人民医院人流费用First, the researchers surveyed more than 1,100 people who had achieved significant weight loss and maintained it.

池州石台县剖腹产多少钱石台医院资料虽然最近在国内也相当盛行吃西餐,但是在内容和形式上,随著各餐厅的经营型态而“纯”、“杂”不等,“繁”、“简”不一,十分值得一谈。   美国的西餐,和欧洲许多国家也颇有不同。如果您到美国旅游,赴家庭宴会或在餐馆吃“正餐”时,请先注意下列一般原则:   1. 男女一起在餐馆用餐,通常由男方负责点菜(order)和付帐(pay the check or bill)。   2. 许多基督教或天主教家庭饭前要由家中一员带领祷告(say a prayer or "blessing"),您即使不信教,也请跟着低头,以示礼貌和尊重。   3. 美国人宴客,是由女主人(或男主人)先拿起餐具进食,客人才跟着动餐具。   4. 如果您不喜欢递过来的菜肴时,只要说"No, thank you."即可。   5. 咀嚼食物,一定要避免出声。   6. 用过的刀、叉,必须放回盘子里,不能放在餐桌巾上。   7. 吃完主菜,把刀和叉平行地斜放在主菜盘(main plate)上,是向主人或侍者表示可以把主菜餐盘拿走了。   8. 席间要轻声谈些轻松愉快的话题,尽量避免一声不响地闷着头吃饭。   下面请看这一段模拟的席间对话:   Hostess: Would you like to have some more chicken ?   Guest: No, thank you. The chicken is very delicious, but I'm just too full.   Host: But I hope you saved room for dessert. Mary makes very good pumpkin pies.   Guest: That sounds very tempting. But I hope we can wait a little while, if you don't mind.   Host: Of course. How about some coffee or tea now ?   Guest: Tea, please. Thanks.   餐位(Seating arrangement)   餐位的安排大致上如上图。原则上男主宾(Gentleman of honor)坐在女主人(hostess)右边,女主宾(lady of honor )坐在男主人(host)右边,而且多半是男女相间而坐,夫妇不坐在一起,以免各自聊家常话而忽略与其他宾客间的交际。 /201002/96181池州市立医院几点上班尧渡仁里蓉城镇人民医院预约是不是真的
