The location function records the user's whereabouts.
In an Apple 5s mobile phone that has been upgraded to version 7. 1. 1, open Settings-Privacy-Location Services-System Services-Frequent Places. It can be seen that, unlike the previous application, the location service icon does not appear in this program function, which is turned on by default. After entering the program, open the frequented places, there are maps, the frequented places are circled in blue, there are detailed place names, and the time of the owner's stay in the place is recorded in detail, which is fast to update. What's more, according to the times and time you have been to these places, the system will automatically mark these places as families and units.
It is understood that this function will appear after the Apple mobile phone is upgraded to version 7.0. What's the use of such a detailed location record? The reporter searched the system introduction of Apple's mobile phone, but he couldn't find a detailed explanation about this function, even the staff in the Apple store couldn't tell clearly.
90% of the interviewed users don't know the details.
In China, Apple's mobile phone has hundreds of millions of users, and every new product of Apple will be sought after by countless people. Do Apple mobile phone users know this hidden function?
The reporter interviewed 60 Apple mobile phone users randomly in three cities, and only 5 of them knew the function of "frequented places", accounting for less than 10%. Many users are surprised to see this function. Some users directly said that this function is suspected of peeping into others' privacy and should be deleted directly. For this function, even the staff of Apple Store don't know what positive effect it has, so it is recommended not to use it.
You can even judge your occupation by analyzing location data.
The staff are not familiar with it, and neither do mobile phone users. Will the privacy leakage problem that users are worried about happen? What private information can you analyze through these seemingly unrelated frequented places?
Martin, dean of the Network Security College of the People's Public Security University of China, told reporters that in the era of big data, some seemingly useless data will get some surprising results after analysis. The reporter handed over the places he often went to on his mobile phone. In a short time, Dean Ma got some very private personal information.
Martin said that according to the analysis of places where people go a lot, that place should be the owner's work unit, and there are CCTV, Air Force Courtyard, Naval Courtyard and Science and Technology Department. According to the irregular time record, and it is all in the daytime, the owner should not be on duty. After analysis, he is a reporter, so CCTV may be his work unit. If he is determined to be a journalist, these scattered points are the workplaces he often interviews. After being able to judge a person's special occupation, the data will be more sensitive after paying attention to and analyzing some people. It is not difficult to see that the function of "frequent places" makes a more detailed analysis of people's behavior trajectory. After using a mobile phone for a long time, there is no secret in the user's whole activity track.
Martin introduced that in the past, data and information were often divided into different security levels. The higher the security level, the better the protection measures. But in the era of big data, it is often not key confidential data that is leaked, but some ordinary daily information. When the number of users is large enough, we can find some regularity from these daily information, which involves the whole national economy and people's livelihood, and even state secrets.
Apple has issued a statement acknowledging that there are loopholes in location collection.
In Apple's mobile phone, why are so many users unaware of this seemingly "to better serve users" function? How does Apple explain this? On the related issues of location service, the reporter sent emails to Apple Headquarters and China Company, hoping to interview the relevant person in charge. A few days later, a staff member in charge of public relations in China Company replied to the reporter with a link address, telling the reporter that this statement can answer the question of location service.
The reporter found this statement in Apple official website. In this statement, Apple does not deny collecting and analyzing the location information of mobile phone users. At the same time, Apple answered ten location-related questions, which mainly mean two: 1. Apple will not reveal user privacy; 2.Apple collects users' location information to better serve users.
Apple issued such a statement because three years ago, two British engineers found that Apple's system contained a file that could record the geographical location where Apple mobile phone users had been, and stored the information by hiding the file. This behavior has aroused people's concern about information security and personal privacy. Subsequently, the governments of Germany, Italy, France and other countries launched an investigation into Apple. Under pressure, Apple issued this statement, acknowledging that there are loopholes in location collection and will fix them.
I suggest you don't open the location information. I think you should understand after reading the above article.
