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.

An image-capture-scope indication device for an image-capture apparatus. The image-capture-scope indication device includes: a light source, fixed on a surface of the image-capture apparatus on which a lens of the image-capture apparatus is provided; a light ray selection member, which is provided in front of the light source and has a light transmission portion; and a drive member. The drive member is configured for moving the light ray selection member so that a scope surrounded by light rays emitted from the light source and passing through the light transmission portion of the light ray selection member is provided that is consistent with an image-capture-scope of the image-capture apparatus.

Executable files are managed. A determination is made as to whether in a second executable file there exists a function that is the same as a function called in a first executable file. A data package is generated on a portion other than the function in the first executable file and the second executable file, and the function is stored in relation to the data package. The data package includes a first address of the function in the first executable file and a second address of the function in the second executable file.

A system for sharing a USB Key by multiple virtual machines located at different hosts including at least two virtual machine managers, each virtual machine manager including a virtual machine transceiver module which is configured to receive a request for accessing a USB Key from a virtual machine within its host; a storage module which is configured to store an association relationship between a USB Key and the virtual machine authenticated by the USB Key; a verification module which is configured to, in response to judging that the virtual machine of the received request can access the USB Key, transmit the request for accessing the USB Key to a USB Key transceiver module of a virtual machine manager of the host where the USB Key is located; and a USB Key transceiver module which is configured to receive a request for accessing a USB Key, and to transmit an access request to a connected USB Key.
