Can big data really monitor personal information?

The content we browse or search is monitored by big data. This is no problem. The problem is that the microphone of the mobile phone is bugged. Sometimes we are talking about something and don't operate the mobile phone at all. A few hours later or the next day, we will find that the mobile phone has already pushed the relevant information.

Many applications require various permissions, such as recording, locating, retrieving short messages and address books. If they like, they can always know where you are, what you are doing, what you are saying and who to contact. In the high-tech era, everyone is streaking. The question is whether others are willing to watch. You want to see something else, want to know something else, but there is nothing at all, just what you see and search, and your vision is getting narrower and narrower. Those who brush their mobile phones every day have not improved at all, and their thinking has become a stereotype, especially for children, whose parents can't control it because their mobile phones are doing what they want to do.

I have met it three times: 1. At that time, I said that I was short of money and might have to swipe my credit card. As a result, the credit card took the initiative to directly raise the amount for me. 2. At the same time, chat with me about how much my credit card cost. As a result, I received a phone call from the bank staff and asked if I wanted a loan. 3. When it comes to children looking at their old age at the age of three, the result pops up directly on the web page: it is the key to make rules for children at the age of three.

The topic is talking at ordinary times, and the focus is talking at ordinary times! I had the same experience. I just spoke to a friend, and my cell phone didn't move. I immediately pushed a related news or advertisement to me. I think one thing is very suspicious, that is, why you should agree to the microphone permission when installing the app! In fact, many apps or platforms, including websites, share a big data. So when something is mentioned in one place, then big data will directly push similar related content in other places. Therefore, in order to be cautious, everyone should pay attention to input some content search!

I have more doubts. When I came back from my trip, I saw my niece had a neck massager. I don't even know its name, and I haven't thought about buying it. Therefore, before this, there was no place to search for this thing in the mobile phone. As a result, just after my niece and I asked about this instrument, I opened a treasure and saw the recommendation of this instrument on the first page ~ Oh, my God, did my mobile phone monitor and eavesdrop on our conversation? This is why it appeared. Really scared. I'm still wondering if my mobile phone will listen to people.

Nowadays, the network processes information through cloud computing, and there is no difference between monitoring a mobile phone and monitoring 100 million mobile phones, so there is no saying that costs and benefits are not proportional. Therefore, this situation is still possible. I can assure you that I have never searched for information about animation on the Internet, because since my children posted many cartoons on the wall, information about animation has appeared on my mobile phone almost every day, and even a large number of cartoons have appeared in my mobile phone's automatic desktop update. Why is this?
