With the explosive development of social networks, our lives are facing unprecedented changes. Usually, we have to give up some personal information for convenience, but these actions are essentially out of trust, but they also expose our information to more criminals.

Facebook is in hot water over allegations that it leaked the data of more than 50 million users during Donald Trump’s election campaign, and that Cambridge Analytica used the data to create profiles that targeted those users during the campaign. And thus lead people to vote as they wish.

The news, the public uproar, feel the unprecedented deception, we know that the law in the privacy of personal information protection is more concerned about this, so facebook is also facing the unprecedented pressure, the company’s share price on Monday the biggest drop in a years, the world’s biggest social networking company’s shares closed down 6.8%, About $36.7bn was wiped off market value. Not only that, but the stock has continued its downward trend.

Mr. Zuckerberg, Facebook’s young chief executive, said he was willing to testify to any U.S. government investigation into recent media reports that Cambridge Analytica had collected data from more than 50 million Facebook accounts, and that he had no objection to his social media company being regulated. At present this matter is still in further investigation processing, there is no accurate result.

However, it is not difficult to see from this incident that even though people pay more and more attention to the protection of personal privacy, it still cannot change the difficulties that privacy protection is facing at present. The leak was limited to the U.S. but is our personal information safe? Unfortunately, the answer is no. Just a quick reminder, how long has it been since you received unwanted texts and cold calls? Those who don’t know in which corner of the unscrupulous business can say your name? Some have even cracked simple passwords based on family members’ birthdates.

Although with the awakening of the public awareness of personal information protection, in the protection of personal information, the attempt to continue to exploit loopholes in the enterprise, sooner or later will be eliminated by the market. But at present, many enterprises and individuals in this awareness is relatively weak, so called for everybody, in place of non-essential or scenario, try not to reveal their true personal information, because don’t know when, this information could into the hands of criminals, so as to bring to your life or big or small.
