Passwords to be replaced by Web Authentication


It looks iike login usernames and passwords are on __(I)__ way out. No longer will we have to worry about the security of __(II)__ login credentiais. They are set to be replaced by an infinitely more secure login system known as Web Authentication. Web Authentication has become an official standard for logging in at the main Internet standards body, the World Wide Web Consortium (WWWC). It is a system that will be universally used by web browsers and platforms for simpier and stronger authentication processes. It will allow website users to iog in securely to their online accounts using a digital device, biometrics (such as fingerprints and facial recognition) or USB security keys.

The WWWC spoke about the days of passwords being numbered. A spokesperson said: "lt’s common knowledge that passwords have outlived their efficacy. Not only are stoien, weak or default passwords behind 81 per cent of data breaches, they are a drain of time and resources." It added: "Now is the time for web Services and businesses to adopt Web Authentication to move beyond vulnerable passwords and help web users improve the security of their online experiences," Web Authentication means users are at less risk of having their passwords and credentiais stoien. This is because login authentication is achieved via physicai vices or biometrics from our body.

                                         Robotic Cars


The year is 2020, and it’s 7;45 on a rainy Monday morning, and you are in your car on your way to work. You turn right, and you turn left. A few minutes later, you stop at a traffic light. When the light turns green and there are no other cars in the intersection, you continue on your way. Ten minutes later you get to work and stop reading the morning paper. Then, you get out of your car and you say, “Thank you!". Your car replies, “You’re welcome!’’. This possibie future may sound unreai, but in fact many car companies are aiready testing robotic cars, or driverless cars, on the roads today, although the cars don't speak very much yet.

In the 1980s, Germany and the United States tested the first driverless cars, and by 2020 companies such as Volvo, GM, Nissan and BMW plan to seil driverless cars. Driverless cars are not really ‘driverless - the drivers are computers that use radar, Computer maps and other modern technology. They offer many advantages. Perhaps the most important of these is fewer deaths caused by road accidents. For example, in 1968 more than 53.000 people lost their lives in car accidents in the USA. This number has fallen to less than 33.000 but it’s still a high number. In addition, people will spend iess time stuck in traffic jams and there will be no need for people to have a driving license. One of the major disadvantages of this new technology, however, is the cost. It’s not free. U$5.000 to U$10.000 is added to the price of the new car. Nevertheless, at some time in your life, you will probably be sitting in a robotic, ;driverless car on your way to work or school. The future is almost here. Are you ready for it?
