According to foreign media reports, 11 months ago, Apple CEO Tim Cook declared privacy a “fundamental human right.”. The company’s customers carry more and more sensitive information on their iPhones, and apple is trying to make privacy a key differentiator from Google and other competitors. < / P > < p > on Wednesday local time, the company tried to live up to that promise by releasing IOS 14. It is understood that it introduces a series of privacy features designed to give iPhone users better control over their personal information. These protections will constrain application developers, online service providers and advertisers, who often break through the boundaries of acceptable data collection. < / P > < p > for a long time, IOS has allowed users to control which applications can use cameras and microphones. Now, Apple has taken another step forward. In IOS 14, users are notified in real time when an app captures audio or video from the phone. It also provides a list of recent apps that have accessed the microphone or camera. < / P > < p > in general, real-time notifications are easily ignored, which may be exactly what Apple wants. The figure below shows the home screen when the iPhone se guitar tuner turns on the microphone. < / P > < p > it is understood that the only indicator is the orange dot to the left of the battery indicator. Privacy conscious users will have to train themselves to find it. However, the reporter pointed out that the notice of visiting the application of microphone recently was not as useful as he thought. According to the latest one, he can only see one or more of the latest applications. There is also a problem: if the application enters the control center more than 30 seconds after it enters the control center, the list will be empty. < / P > < p > these post event notifications will appear at the top of the control center. The following is a picture of a reporter turning on the access camera and opening the authentication program for the guitar tuner accessing my microphone for about 20 seconds: < / P > < p > these restrictions greatly reduce the value of the control center notification because it requires users to visit the control center as soon as possible and frequently. This is more useful if the list can be refreshed every two to six hours and shows all the apps that have visited the microphone or camera during that time. < / P > < p > before IOS 14, users had two choices: either allow apps to access all stored photos, or disable them. Now users have a new option – allow the app to access one or more specific photos, while others are still blocked. I believe this is an unexpected feature for many users. Some applications have good reasons to visit local networks. Like an app that interacts with a smart TV and uses Bluetooth to sense whether the phone is nearby. This is the first time my reporter opened Samsung’s app on IOS 14: < / P > < p > once upon a time, IOS users could grant or deny access to the location of an app, and the location could be accurate to the physical address. You can now have a new choice of the nearest location. This is useful for a stargazing application, which may require a general location but not an exact location. < / P > < p > IOS now provides a notification whenever an app accesses the clipboard. This is very useful because the clipboard usually stores passwords, encrypted currency wallet credentials, and other highly sensitive information. Now that IOS can access the clipboards of nearby Macs connected to the same icloud account, this function is even more important. < / P > < p > IOS can now access a database of known compromised passwords and alert users when passwords stored in the key chain password manager appear in the list. Apple said it was done in a secure, private way and would not even disclose the user’s password to apple. The company did not specify how to do it. Wired’s explanation for this is that it may be similar to the clever encryption technology behind Apple’s findmy app. After IOS 14 comes into effect, app developers must disclose privacy protection measures to apple. The required details include any location, contact information, purchase status, browsing history, personal financial status, and collection of unique identifiers. < / P > < p > surprisingly, apple is only now fully randomizing Wi Fi chips to identify its MAC address points to Wi Fi access. These fixed addresses are useful when a trusted network wants to control or at least identify the devices that are allowed to connect. < / P > < p > the problem is that passing through two or more networks controlled by the same person or organization is sufficient for operators to compile a list of equipment and then cross reference them. As time goes on, more historical information is leaked. As a result, access points can record users’ deepest secrets, including when they left the bar last night, who left with them, and their route home. In 2014, with the introduction of IOS 8, apple added MAC randomization, but researchers and users quickly found that this method has a key limitation, that is, this method can only be effective if the device probes to find the previously connected network. According to an article on the apple news website imore, randomization does not happen when a device is connected to a device. However, apple finally solved this limitation. By default, IOS 14 will use a “private address,” and apple refers to a randomly generated unique MAC for a particular network. To disable this feature, the user needs to turn off private address in SSID settings. However, according to the reporter, this function is not as powerful as he wants. Ideally, it changes MAC addresses periodically or allows users to change them manually, so a single Wi Fi network cannot track users for a long time. According to the reporter’s brief test, the random address seems to be permanently bound to a given SSID, even if the IOS is told to forget the network and log in again. < / P > < p > Safari now provides a privacy report that summarizes the trackers users have encountered in the past 30 days. Click on the two letters on the left side of the address bar to access it. < / P > < p > and one of the most anticipated privacy features is that application developers must obtain the user’s consent before tracking users’ activities on third-party applications and websites. Unfortunately, Apple has delayed the implementation of this feature, as early as next year, after complaints from app developers, especially Facebook’s instagram developers. < / P > < p > for a company that claims privacy as a fundamental human right, this is no doubt surprising. Fortunately, IOS 14 has enough other privacy features, which makes IOS 14 a big improvement over previous versions. Global Tech
