Abstract: Provided in the present application are a shielding cover, a circuit board assembly and an electronic device. The shielding cover comprises a cover body, wherein the cover body and a circuit board together enclose a shielding region, in which at least some components on the circuit board are covered. The components inside the cover body include a first device, which has a stepped face facing the cover body, and the region of the cover body that corresponds to the stepped face of the first device is provided with a strengthening portion, with at least part of the structure thereof being located in the region of the cover body that directly faces the stepped face, so as to make use of the space formed above the stepped face of the first device. The strengthening portion is additionally provided to increase the strength of the cover body and prevent collapse of the region around the part of the cover body that corresponds to the stepped face, thereby improving the stability and reliability of the shielding cover. Moreover, the spacing between the first device and an adjacent component thereof remains unchanged or has a reduced rate of increase, such that the circuit board maintains a densely arranged layout structure, thereby saving on the layout area of the components of the circuit board, and improving the space utilization of the circuit board.

Abstract: The present application provides an access control method and a related apparatus. In the present method, when an electronic device is in a locked state, after an operation instruction and identity authentication information that does not meet an unlock requirement are acquired, it may be determined whether to allow access to a resource that the operation instruction requests to access. If so, the corresponding resource is accessed in response to the operation instruction. In implementing the present method, a user does not need to unlock the electronic device by means of tedious authentication, that is, the user may trigger the electronic device to access the corresponding resource in the locked state, so that the user can easily and conveniently control the electronic device. In addition, the electronic device no longer determines whether to perform some operations according to whether it is unlocked. In this way, fine-grained access control can be implemented, which enriches use scenarios and use scope of the electronic device.
