Problems solved by technology
However, as more and more software is installed on the end user's PC machine, different software performs non-compliant scanning and device port operations on USB devices (such as dongles), and some conflicts occur, resulting in normal software (For example, the software that needs to be decrypted by the dongle to start or use normally) cannot access the dongle, and the client software cannot be started, but the final customer (that is, the software user) does not know which software causes the conflict, and the final customer is helpless when encountering this problem. , can only contact software developers and dongle suppliers
[0003] In the prior art, the software cannot find a specific USB device (such as a dongle) every time the software is started, and the software user needs to start it manually, and judge whether there is process interference, and manually close it, which makes it difficult for the majority of software users to learn and operate

The invention discloses a control method and device for accessing an external device by an application program, and the method comprises the steps: intercepting the process of a first application program when the first application program calls a first function, wherein the first function is any function required to be called for accessing the first external equipment; if the device information of the first external device is matched with the device information of the second external device and the identification information of the first application program is matched with the identification information of the second application program, releasing or refusing the intercepted process of the first application program, wherein the device information of the second external device corresponds to the identification information of the second application program. According to the method and device, the process of accessing the application program of the external equipment is intercepted firstly, and then when the external equipment is the specific external equipment and the application program is the application program meeting the preset requirement, the intercepted process of the application program is released or refused, so that the accurate control of accessing the external equipment by the application program is achieved, and the access accuracy, security and access efficiency are improved.
Description
technical field [0001] The present application relates to the technical field of computer software, in particular to a method and device for controlling application programs to access external devices. Background technique [0002] Many dongles on the market are installed on PCs, especially PCs with Windows systems, using driverless or driven methods, and the software protected by the dongle accesses the dongle through API. Among them, the driver-free mode uses the ergonomic device driver that comes with Windows, thus avoiding the need to install the driver, reducing the size of the driver installation package and bringing the software installation package, and the user can immediately insert and use it immediately, reducing the difficulty of software installation , loved by the majority of software developers. However, as more and more software is installed on the end user's PC machine, different software performs non-compliant scanning and device port operations on USB de...
