Social networking originates from social networking, and the starting point of social networking is email. Internet is essentially the networking between computers. Early E-mail solved the problem of long-distance mail transmission, and it is also the most popular application on the Internet, and it is also the starting point of network socialization. BBS goes a step further, normalizing "mass sending" and "forwarding", and theoretically realizing the function of releasing information to everyone and discussing topics (the boundary is the number of BBS visitors). BBS advances the social networking one step further, from the simple point-to-point communication cost reduction to the point-to-point communication cost reduction. Instant messaging (IM) and Blog are more like upgraded versions of the first two social tools. The former improves instant effect (transmission speed) and simultaneous communication ability (parallel processing). The latter begins to embody the theory of sociology and psychology-information publishing nodes begin to embody stronger individual consciousness, because scattered information in the time dimension can be aggregated and then become the "image" and "character" of information publishing nodes. For example, RSS, flickr, YouTube, Digg, Mini-feed, Twitter, Fexion and Video-Mail have all solved or improved a single function, which is a tool to enrich social networking. With the quiet evolution of social networking, a person's image on the network tends to be more complete, and then social networking appears. Making friends is just the beginning of social networking, just as the beginning of Google is just as common as the backlinks of every web page, the beginning of social networking is just to get your personal data and friends list. Generally speaking, social networks have gone through such a development process: the early conceptualization stage-the six-degree separation theory represented by ——SixDegrees; The stage of making friends with strangers-the theory that ——Friendster helps you build weak relationships and thus bring higher social capital; Entertainment stage-the theory that ——MySpace creates rich multimedia personalized space to attract attention; Social graph stage-Facebook replicates the theory that offline real interpersonal network comes to online low-cost management. The whole development process of SNS is that people gradually transfer the more complete information flow of offline life to online for low-cost management, which makes virtual social interaction more and more cross with real-world social interaction. In the history of mankind, most important technological revolutions are accompanied by media revolutions. Any human activity is essentially an information activity. Different transmission media and management methods of information flow will determine the difference in how you receive information. All changes in information flow media must be bottom-level changes-so is social networking. From the evolution history of social networking, it has been following the principle of "low-cost substitution". Network socialization has been reducing people's social time and material costs, or reducing the cost of managing and transmitting information. At the same time, online social interaction has been trying to replace traditional social interaction by constantly enriching means and tools to meet the communication needs of social animals like human beings, and it is approaching the basic needs according to the trajectory from "incremental entertainment" to "constant life". If we say that in the era of e-mail, the network can only meet 5% of people's social needs, then today's rich social networks can increase this number by at least 1 times. In addition to "contact" social behavior, or the collection and release of "contact" information, online social interaction has begun to assume most of the traditional social functions. In fact, "non-contact" social interaction has already occupied more than 8% of human social interaction, which means that online social interaction will inevitably have a great impact on the traditional world. In the final analysis, social networking is not only some trendy business models, but also a key force to push the Internet infinitely closer to the real world from a historical perspective. At present, social networks cover all forms of network services with human socialization as the core. The Internet is an interactive platform that can communicate with each other, communicate with each other and participate in each other. The development of the Internet has already surpassed the original military and technical purposes of ARPANET. Social networks have expanded the Internet from research departments, schools, governments and commercial application platforms to a tool for human social communication. Nowadays, social networking has expanded its scope to the field of mobile phone platform. With the help of the popularity of mobile phones and the application of wireless networks, mobile phones have become the carrier of new social networks by using various software such as dating/instant messaging/email transceivers. Social network, that is, network+social. Connect people through the network, thus forming a group with a certain characteristic.

edit the security of this paragraph

according to a recent survey from Webroot, a security software company, users of social networking sites are more likely to encounter security threats such as financial information loss, identity information theft and malware infection, and their seriousness may exceed their own imagination. The survey found that two-thirds of the respondents did not take strict measures to protect their personal information on social networking sites, others could view these sensitive information through search engines such as Google\Baidu, and more than half of the respondents did not know who could view their personal information. About one-third of the respondents said that their social networking site profiles contain at least three kinds of personally identifiable information, and more than one-third of them use the same password on multiple websites. In addition, one third of people accept Friend Request from strangers. Mike Kronenberg, chief technology officer of Webroot's consumer business, said, "The growth of social networking sites has become a huge target for hackers. Last year, the time people spent on social networking sites such as Facebook increased by three times the growth rate of the entire Internet. " Klemberg said, "Three out of ten people we surveyed have experienced security attacks on social networking sites, including personal identity theft, malware infection, spam, unauthorized password modification and phishing fraud. The first step to achieve security protection is to recognize the types of security threats and then understand how to protect them. " Computer criminals use different types of deception and malware to take advantage of risky behavior. A common strategy is phishing, in which hackers trick users into downloading an infected file, visiting risky websites other than social networking sites or sending money to a "friend in trouble." Webroot said that such attacks on social networking sites have been on the rise in recent months. After hijacking the account of a social networking site user, the hacker sends a message to his contact to deceive the other party into improper behavior.
