Today, computer equipment has been integrated into one by the network. Before, we thought that a computer was a computing device, but now we habitually regard it as a device as a network terminal. The development of network infrastructure has moved our storage and computing online, and the computers and mobile phones at hand are just resources to call online hosts. The construction of the network makes the tasks of local equipment simpler. Just connect to the Internet to perform a lot of tasks that originally required powerful geological resources, which also contributes to the miniaturization of network terminal equipment. The frequent data exchange between hosts and terminals has ultimately led to the rapid rise of big data, most of which are personal data. The development of
cloud is based on the maturity of conditions such as network infrastructure, miniaturization of terminal equipment, and data chain construction. cloud service ranges from the sharing of basic computing and storage resources to the formation of comprehensive online services today. The rapid development of the cloud comes after the rise of social networks. The emergence of social networks puts higher requirements for individuals to use cyberspace. Before the advent of social networks, the network rarely had to deal with the situation where hundreds of millions of users were performing complex operations online at the same time. This is different from search engines. Social networks need to perform operations such as image upload, text editing, information classification, and data link integration, including search. Such complex requirements will eventually lead to complex cloud computing systems.
As cloud computing becomes the mainstream of network usage and frequent data exchange between terminal devices and the cloud, issues of protection measures and responsibility identification of personal information in the cloud computing environment have also been pushed to the forefront. Because when the Internet first appeared, sharing of information on the Internet was the credit of the builder at that time. However, with more and more ordinary users who do not have such consensus, and their willingness to protect information cannot be concealed by the original network value, society is increasingly convinced that the protection of personal information should be strengthened and the Internet that is too open is transformed based on this purpose.
Recently, due to the bad social impact of network and telecommunications fraud, my country has increased its efforts in personal information security . In fact, protecting personal information was a very important issue several years ago. Because for the Internet, a series of personal situations will be recorded in the form of data, and due to the strong replication and dissemination characteristics of the Internet, once an individual logs into the Internet, he will become a transparent person. If the Internet had human consciousness, it would be the person in the world who knows us the most. Our name, email, phone number, address, action route, credit card information, income status, children's status, marriage, emotions, hobbies, etc. are all recorded by tags and social network status. After integrating these data, a person's basic situation will naturally appear in front of us in three-dimensional way. If this data is analyzed, you can clearly know the situation of each person, which will be a great threat to the security of personal information.
Generally speaking, human and psychological defects are difficult to overcome. Social Engineering is to use the weaknesses of human nature to launch attacks, making people unable to defend themselves. Social engineers with excellent skills are good at collecting information, and first of all, they must be a good intelligence worker. Many information that seems useless on the surface will be used by these people, such as a phone number, a name, an ID number or a business card. Social engineering is actually the collection and utilization of information, which is essentially a fraud. Since it is not particularly close to network security technology, this is not a technical issue in network security construction, but a management mechanism issue.
So far, we can raise our concerns about information security today: cloud computing exposes personal information too much to the public's attention; network devices record personal information in a very detailed way; social engineering deception is prevalent, and cloud provides social engineering attackers with a very good way to collect personal information. This is why we should value personal information protection so much today.
The personal information in the network is mainly divided into the following types.① Personal real information: name, ID card, mobile phone number, education, occupation, bank card, social security information; ② Information related to fund accounts: online banking ID, Alipay , WeChat, securities accounts, etc.; ③ Ordinary online account information connected to real information: QQ number, WeChat, Weibo , email, second-hand trading platform, etc.; ④ Other account information: various forums, small websites, etc. Generally, you can obtain someone's QQ number and mobile phone number, and combine it with an APP that can apply for mobile address book permissions, and you can fully obtain the person's personal information. From the current perspective, mobile phones are the fastest source of personal information leakage, and they deserve everyone's attention to protection.
Most of the information leaked on mobile phones is directly related to property, and the easiest way to leak includes e-commerce APP. E-commerce often conducts market data research with third-party advertising data companies to improve the advertising system. Others include bank, securities, , insurance and other ID information and transaction information. In some cases, in order to avoid the cumbersome process of registering an account, we will use the QQ number, WeChat, and Weibo third-party accounts provided by the website to log in. This is equivalent to actively disclose the information of your third-party account to the other party. If the authorized website has a vulnerability in network security, the personal information of this website and the personal information of the third-party account will be completely leaked. And these leaked information will flow into the hands of social engineering attackers through various underground channels.
More than 90 countries have legislated protections for personal privacy. Let us reiterate here that in the Internet era, the protection of personal information faces huge challenges. In terms of infrastructure, whether it is the hardware encryption protection of cloud computing or the offensive and defense cooperation of network security mechanisms, they are technical issues. The bad consequences of today's personal information leakage are not entirely due to infrastructure, but because there has never been a perfect system. In the future, the protection of personal information will be a process of continuous improvement of laws and regulations and social constraint mechanisms. It is difficult for the Internet to fundamentally change its open structure as it has developed to this day. Since we are no longer in the process of "not closing our doors at night", the only option is to build a safe community. The emergence of social media tools has made online public opinion a question that all sectors of society pay attention to. Among them, unhealthy online behaviors spread under the agitation of interests, and most netizens mainly receive information and onlookers, and did not participate in the public opinion duel. In fact, there is a huge distance between online public opinion and real public opinion, so when facing online public opinion, you should maintain a rational attitude, because if you attach too much importance to online public opinion, the interests of the silent person will be violated.
"Group polarization" in the Internet is likely to breed extreme views, which we can see very clearly in this US election . Looking at previous US elections, during the party’s primary election, candidates have won party nominations with extreme views, which has almost become their only strategy. In fact, this strategy is also supported by statistics and game theory . Extreme remarks have great energy in gaining group recognition. Especially today with the development of social media, people are designated by the social media circle as countless circles with special opinions and opinions.
Each group has its own clear propositions and politic tendencies. In addition to the limitations of words and space on social media, countless extreme remarks lacking causes and consequences are spread from social networks and spread among various online communities. The online community will process it according to its own propositions and politic tendencies and spread it again. All the communication processes mentioned just now require careful preparation and professional editing, and these professional abilities are not available to ordinary netizens. Today, it can be said to be the era in human history with the most production and the widest spread of incitement speech.
The Internet does not reflect our real society, and it is impossible to be true. From the moment the Internet becomes a social infrastructure, it becomes an important resource. This is why we say that under the surface of the Internet's open democracy, there is the silence and at a loss among the majority of netizens, not to mention the poor people who do not have the conditions for accessing the Internet so far.
