We all know Facebook, and most of us already have an account. Anywhere you can use Facebook to create accounts on various websites, or you can see small squares with white "f" on the blue background of advertisements, television and magazines. Including 20 people - Indian personality candidate of that year (Burt, Stephen). Within a few years, an easy way to return to a former girlfriend has grown to be the largest social network.
Using the Facebook advertising platform, the card game 'Super Predator' political advertisement targeted some African American voters through Facebook 'dark post'. (So far, Facebook refuses to publish the political advertisement and its audience target parameters Trump's "Hillary think African-Americans are super-predators"). Exercises usually cost millions of dollars for data science to understand their own potential supporters - although they may have become reliable messengers - in the end, Mr. Trump In order to prevent African Americans and young women from voting and to gain a good return for the president's victory, he made a risk-bet on the micro target's Facebook advertisement.
I think that it is a good use example now. Recently I saw the activity of # deletefacebook. Since Facebook has become a large-scale centralized company, we manage data of all users and sell user's data to the utmost by utilizing it without user's consent. They manipulate data to get the results they want. Facebook has controlled many large companies such as Google, Amazon, Netflix, as well as the Internet. All of these huge companies manage user's data, own user's data, and manipulate user's data to get the necessary results.
Facebook is very disappointed with how users manage our own data. More importantly, Facebook can not even use my data in a way that is beneficial to my end users, products, and services. If this is not a failure of a technology company, I do not know honestly what it is.
To what extent do you feel uncomfortable, how much does Facebook manage your personal information? Otherwise, you should do it. It is certainly not safe to allow Facebook (or other company) to own and manage your identity on the Internet, but fortunately the new technology means that it is not necessary. By using a common block chain to preserve your identity, you can easily log in to another place without being hacked, and you know who you are I will. There are thousands of interesting things in the block chain, but in this discussion this simple definition is enough. Public block chain is a new database maintained by thousands of different people and companies. The information written to the database is permanent - it can not be changed or lost, as all of these different people are vested in economic interests and can keep the same database up to date.
