According to foreign media reports recently, the German Data Protection and Information Freedom Commissioner in Hamburg has ordered Facebook to stop collecting and storing user information through its real-time communication software, WhatsApp, and to delete all previously acquired information related to German users. Two years ago, Facebook acquired WhatsApp for $19 billion. In these two years, WhatsApp gradually became one of the most popular real-time communication software in the world. In 2015, its total subscribers reached 900 million users, of which the total number of daily messages sent by common users exceeded 30 billion. Just think, such a huge user base, so massive information data, once the user privacy is not guaranteed, it is quite terrible. According to the allegations of the German privacy regulator, Facebook and WhatsApp have assured users that they will not infringe on the privacy of users and share their personal data, but Facebook did not say it and it was disappointing. In an interview with Reuters, Facebook said that in order to solve this problem, the company is working with Hamburg regulators. At the same time, the regulatory agencies in the United States and the European Union are also investigating the changes in the privacy policy of WhatsApp. In fact, WhatsApp's privacy settings have always been criticized. As early as 2013, the Canadian Privacy Commission in Canada found that the software collects many phone numbers of non-WhatsApp users by looking at the user's address book and inappropriate encrypted information. In 2015, the Dutch university student Maikel Zweerink independently developed a software called WhatsSpy. It exploited WhatsApp's online design choices as “Design Vulnerabilities†to confirm that WhatsApp did indeed have security holes. Then, with strict supervision, what will WhatsApp do? We wait and see what happens. Chaff Cutter,Chaff Cutter Machine,Mini Chaff Cutter,Hand Chaff Cutter Hunan Furui Mechanical and Electrical Equipment Manufacturing Co., Ltd. , https://www.thresher.nl
