What is the SDK mentioned at the 3 15 party? What software has SDK plug-ins?

What are the so-called laws and regulations in the world of mobile app? Third-party applications or services? It is a tangible existence. But in fact, whether it is the news push you receive every day, or the promotion advertisement, or even the SMS verification code, it may come from a third party. These third-party toolkits integrated in applications are called SDK. SDK is? Software development kit? Software development toolkit is generally a collection of development tools used by some software engineers to build application software for specific software packages, software frameworks, hardware platforms, operating systems, etc. Simply put, it is a software toolkit to realize product functions through third-party service providers. Usually, SDK will provide a series of professional services provided by professional companies, such as mobile payment technology, voice recognition technology and our company's one-click login technology. Developers don't need to develop every function of the product, and they can use the appropriate SDK to realize the function of the product in less time. Without users' knowledge, Shanghai Krypton Information Technology and Beijing Cai Zhao Want Want Information Technology secretly stole users' privacy, including IMEI, IMSI, operator information, telephone number, SMS records, address book, application installation list and sensor information, by implanting SDK plug-ins (a kind of software package) in more than 50 mobile phone apps. To make matters worse, after these private information is read, the two companies will quietly transfer the data to the designated server for storage. Once users have the verification code of online transactions, it is very likely to cause serious economic losses. Apart from obtaining private information such as SMS verification code, you may not know that if these SDK plug-ins can read the sensor information of mobile phone users, does that mean it is possible? Eavesdropping? Everyone. You can check whether there are more than 50 exposed apps installed in your mobile phone. If there are, it is recommended to consider uninstalling.
