Abstract

Sensitive data is protected in a software product. A source file of the software product is compiled to generate an object file, in which the source file includes at least one piece of sensitive data marked with a specific identifier. The object file has a secure data section for saving storage information of the at least one piece of sensitive data at compile-time and run-time. The object file is linked to generate an executable file. The executable file updates the secure data section at run-time. Sensitive data is also protected when a core dump is generated.

Description

technical field [0001] The invention relates to a sensitive data protection technology, in particular to a method and a device for protecting sensitive data in a software product from being leaked during memory dumping. Background technique [0002] Most existing operating systems and software products support a memory dump (core dump) mechanism. When an exception occurs during the running of a software product, the operating system will perform a memory dump and generate a memory dump file. In the memory dump file, the data in the memory at the moment when the exception occurs is saved, and these data are helpful for fault analysis. It can be understood that the occurrence of many abnormalities depends on specific types of data in the operating environment, so it is difficult to reproduce such abnormalities in the test environment. The memory dump file can truly record the state of the computer memory when an exception occurs. Therefore, the data in the memory dump file ...
