Is the data stored in the cloud confidential or public?

Most people know that data stored in the cloud is different from the data stored and protected behind the corporate firewall at the level of security and confidentiality. But some recent news emotional evidence of how insecure the data stored in the cloud is. My colleague Howard Marks (Howardmarks) recently wrote an article on the Dropbox cloud storage service and its exposure to user accounts in dangerous situations. Because of this problem, Howard and many other users are no longer using the Dropbox service. Of course, Dropbox is not just a serious problem that could leak user accounts. In fact, Dropbox also keeps the key to data encryption, which means that anyone else can see the user's data content as long as they are willing or forced to hand over those keys. The importance of allowing others to access user data is more clearly reflected in Microsoft's latest release of Office365. Microsoft has admitted that it will provide government agencies with data on European corporate users if data from European corporate users is the object of the Patriot Act survey or the data requirements of the relevant government departments. The data is stored on servers in Europe. Now everyone knows that data stored on servers in the United States may be handed over to the government for the Patriot Act inquiry, and that the companies and individuals who own the data do not even know that their data is being submitted. But I think many companies, especially those overseas, will be surprised by the U.S. government's request for U.S. service providers to provide data on servers kept overseas. But when I learned about the situation, I felt unusually angry. Is it only in the American government and the Patriot Act? Would they agree if the Chinese government or other governments asked a multinational company with a wide range of businesses to submit data on U.S. companies that are stored on U.S. servers? I personally think that a considerable number of companies will be very happy to cooperate with the Government. Since the Chinese government owns a certain stake in all the companies, we have to consider whether your data will fall into the hands of competitors. Finally, these situations are a good illustration of the importance of encrypting the data stored in the cloud and keeping the key in the enterprise's own hands. If the cloud service provider cannot decrypt your data, they will not be able to submit data. It also demonstrates the need to promote a private cloud, where corporate users can enjoy the benefits of cloud computing and virtualization technology without worrying about data security. Because if your data is stored on other people's servers and they can see or decrypt that data, then that data is no longer your data.
