(2021·山东省潍坊市五县联考)This year rearchers expect the world to snap 1．35 trillion photographs, or about 3．7 billion per day. All tho pixels (像素) take up a lot of room if they are stored on personal computers or phones, which is one reason why many people store their images in the cloud. But unlike a hard on drive which can be encrypted neversaygoodbye歌词>第一次爱的人英语版
to protect its data, cloud storage urs have to trust that a tech platform will keep their private pictures safe. Now a team of Columbia University computer scientists has developed a tool to encrypt(加密) images stored on many popular cloud rvices while allowing authorized urs to brow and display their photographs as usual.
Malicious(恶意的) attempts to access or leak cloudbad photographs can expo personal information. In November 2019, for example, a bug in the popular photograph storage app Google Photos mistakenly shared some urs’ private videos with strangers. Security experts also worry about employees at cloud storage companies on purpo accessing urs’ images.
So the Columbia rearchers came up with a system called Easy Secure Photos (ESP), which they prented at a recent conference. “We wanted to e if we could make it possible to encrypt data while using existing rvices，” says computer scientist Jason Nieh, one of the developers of ESP. “Everyone wants to stay with Google Photos and not have to register on a new encryptedimage cloud storage rvice. ”
To overcome this problem, they created a tool that prerves blocks of pixels but moves them around to effectively hide the photograph. First, ESP’s algorithm (算法) divides a photograph into three parate files, each one containing the image’s red, green or blue colour data. Then the system hides the pixel blocks around among the three files (allowing a block from the red file, for instance, to hide out in the green or blue ones)．But the program does nothing within the pixel blocks, where all the image processing happens. As a result, the files remain unchanged images but end up looking like grainy blackandwhite ones to anyone who access them without the decryption (解密) key.
