2018届上海各区高三英语一模——summary汇编

【2018宝山区—一模】 IV. Summary Writing Secure payment without leaving a trace Computer scientist Andy Rupp, member of the “Signaling Code and Security” working group, is always surprised about lacking problem awareness: only few users are aware of the fact that by using payment systems they disclose in detail how and what they consume or which routes they have taken. To prevent control of the accounts by dishonest users, customer data and account balances of payment are usually carried out with the help of a central database. In every payment deal, the customer is identified and the details of her/his deal are transmitted to the central database. This repeated identification process produces a data trace that might be misused by the provider or third parties. The expert has now presented the basics of an “electronic purse” that works by unknown names, but prevents misuse at the same time. The “black-box addition plus” (BBA+) code system developed by them transfers all necessary account data to the card used or the smartphone and guarantees their secrets with the help of signaling code methods. At the same time, BBA+ offers security guarantees for the operator of the payment system: The code system guarantees a correct account balance and is mathematically constructed such that the identity of the user is disclosed as soon as the attempt is made to pay with a controlled account. “Our new code system guarantees privacy and security for customers during offline operation as well,” Andy Rupp says. “This is needed for ensuring the payment system’s suitability for daily use. Think of a subway doorway or a payment bridge. There you may have no internet connection at all or it is very slow.” Also its high efficiency makes the code system suited for everyday use: During first test runs, researchers completed payments within about one second. ①when customers use payment systems, most of them don’t realize the fact that by doing so, they risk( take the risk of ) losing privacy. ②Researchers have now developed a secure system called BBA+, which works anonymously and avoids misuses as well. ③moreover ( apart from / besides the security of privacy), it also proves to be efficient for daily use.(47 words) 【2018—崇明区一模】 IV.
