23、 D This year researchers expect the world to snap 1.35 trillion photographs,or about 3.7 billion per day.All those pixels(像素)take up a lot of room if they are stored on personal computers or s phones,which is one reason why many people store their images in the cloud.But unlike a hard on drive which
24、 can be encrypted to protect its data,cloud storage users 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 services while allowing authorized users to
25、browse and display their photographs as usual.Malicious(恶意的)attempts to access or leak cloud-based photographs can expose personal information.In November 2019,for example,a bug in the popular photograph storage app Google Photos mistakenly shared some users private videos with strangers.Security ex

27、ng services,”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 encrypted-image cloud storage service.”To overcome this problem,they created a tool that preserves blocks of pixels but moves them around to effec
28、tively hide the photograph.First,ESPs algorithm(算法)divides a photograph into three separate files,each one containing the images red,green or blue color1 data.Then the system hides the pixel blocks around among these three files(allowing a block from the red file,for instance,to hide out in the gree
29、n 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 black-and-white ones to anyone who accesses them without the decryption(解密)key.12.Whats probably the main purpose f
30、or people to store images in the cloud?A.To save storage room.B.To make photos beautiful.C.To try a new storage way.D.To keep their privacy safe.13.Why might employees in cloud storage companies be distrusted by experts?A.They sell users passwords.B.They have invented new tools.C.They often let out
31、personal information.D.They may steal a glance at users images.14.Whats the advantage of ESP?A.It can provide clear images.B.It can decrease the upload time.C.It can classify images automatically.D.It can encrypt data on the original platform.15.What does paragraph 4 mainly talk about?A.Method of de
