SDK is software or plug-in! ~ or something else?

SDK generally refers to software development toolkit.

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.

Software development tools include a collection of related documents, examples and tools, which generally refer to helping to develop a certain type of software.

In order to encourage developers to use their systems or languages, many SDK are provided free of charge. Software engineers usually get software development packages from the target system developers, or download them directly from the Internet, sometimes as marketing tools. For example, marketing companies will provide SDK for free to encourage people to use it, which will attract more people to buy its components because they can program for free.

Privacy risk of SDK

On October 20 19 1 1 year 10, Shanghai Consumer Protection Committee entrusted a third-party company to conduct special inspection on some SDK plug-ins in mobile phone software, and found that some SDK had hidden dangers. They will read the IMEI, IMSI, operator information, phone number, SMS record, address book, application installation list and sensor information of the device.

The SDK in these apps is only the first step to read user privacy information. After reading, the data will be quietly transferred to the designated server for storage.

The SDK of Beijing Cai Zhao Want Want Information Technology Co., Ltd. is even suspected of stealing more private information from users through recipes, parents' help, dynamic wallpaper and other software. Because SDK can collect users' short messages and application installation information, once users have the verification code of online transactions, it is very likely to cause serious economic losses.
