How to identify all kinds of calls of unknown origin?

The first one is an eight-digit number starting with 95. As we all know, the five digits at the beginning of 95 are mostly the official numbers of banks or express delivery. But if it's 8 digits starting with 95, or even many digits are the same as garbled, be careful. It's best not to answer it at all, because it's basically fraud or harassing calls.

Second, there is a number with a+sign or 00. This number is an international call. If you have no friends or relatives abroad, please don't answer, because once you answer, all kinds of high-tech technologies are likely to reveal your personal information and then use your personal information to deceive your friends and relatives.

Third, it is a number starting with 400 or 800. This number is mostly the marketing number registered by the enterprise company, which is mostly used to promote products. If there is no development demand, you can also hang up directly.

Another is that the mobile phone automatically recognizes and displays it as a harassing or fraudulent call. We can set the mobile phone to automatically block, and the world will be much cleaner immediately!

But there is a call that we have to answer, and that is 96 1 10. This is the official number of the anti-fraud center. When this call comes, it means that you or your family are probably being cheated by electricity. What kind of phone calls have you received? In recent years, apps have become popular, and mobile apps have become the hardest hit areas for personal information disclosure. Excessive collection of personal information through the APP and then selling it is very serious.

According to the "Internet Network Security Status in China in the First Half of 20 19" released by the National Internet Emergency Center, 5 million apps collected an average of 20 items of personal information and device information, and the top 1,000 apps applied for an average of 25 rights, among which the number of apps applying for calling rights unrelated to business accounted for more than 30%, and a large number of apps had abnormal behaviors such as detecting other apps or reading and writing user device files.

According to the survey report on personal information leakage of APP released by China Consumers Association in August last year, 85.2% of the respondents have encountered personal information leakage. Among the main ways of personal information leakage, 62.2% were collected without my consent, 6 1% were intentionally leaked and sold, and 57.4% were system vulnerabilities.

After the information of these people was leaked, the proportion of harassing, fraudulent calls and spam messages received through sales calls or text messages was 86.5%, 75.0% and 63.4% respectively. The author is also suffering from it. Recently, there have been harassing calls every day on average, which is annoying!

It can be said that the excessive collection of personal information by mobile App shows a general trend, especially the communication and location information of mobile phone. And you have to let him get this information for many apps, otherwise you can't install them. This has caused many people to never look at or occasionally look at the application permissions and user agreements or privacy policies when installing the app. Even if they look at the agreements, most of them just look at them.

It can be said that the serious disclosure of personal information in mobile App is related to people's weak security awareness, but more importantly, under the conditions of imperfect laws, inadequate supervision, lax punishment or even no punishment measures, enterprises simply do not pay attention to the safety of users' personal data.
