Embodiment Construction
[0021] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] figure 1 Shown is a flow chart of pre-installed software injection and hidden operation of the present invention, as figure 1 as shown, figure 2 Shown is a schematic diagram of the pre-installed software injection process, such as figure 2 as shown,
[0023] Step 1: In the factory environment host, bypass the host file system, directly call the NVMe driver, and issue NVMe private commands (private hidden area write commands);
[0024] Step 2: In the host machine in the factory environment, the master controller of the solid state disk receives and recognizes the private hidden area write command and executes it, and writes the protected file into the hidden area;
[0025] For the protected program that nee...

The invention relates to a safety protection method for hidden operation of pre-installed software. The device comprises a main body and an auxiliary body, a solid state disk storage area is divided into a visible area and a hidden area; a host system can only identify the visible region; a private hidden area command is used for operating the hidden area; protected programs and data files are injected before delivery; a mapping mark stored in a visible area is used for being stored in the visible area, a hidden area comprises protected executable programs, the mapping mark is used for starting the protected executable programs, and data file operation is carried out by maintaining a file directory table with the unchanged position for each protected program. According to the invention, the requirement that pre-installed software and data are invisible to a user is solved; usage limitation of the hard disk cannot be visually perceived by a user basically in the using process. Meanwhile, conflict with an existing safety protection technology is avoided, the method is a beneficial supplement of the existing software safety protection technology, the safety effect can be implemented and improved at the same time, and safety and reliability of data and a system are improved.
Description
technical field [0001] The invention relates to a special software security protection technology, in particular to a security protection method for software pre-installed in a solid-state hard disk by a manufacturer. Background technique [0002] With the development of computer technology, more and more attention has been paid to software intellectual property rights, and software has increasingly become the core asset of many hardware-software products. Comprehensive software security protection has become a must. In many fields, when the whole machine system is sold, the whole machine carries the seller's special software, and the user must use the special software to complete the use of the whole machine product, such as CNC machine tools and their special software, weapons and equipment If the software is copied, it will greatly damage the interests of the seller. [0003] Many existing security protection technologies have largely solved the problem of software copy ...
