Abstract: An information processing method, a terminal device, and a network system include encrypting, by a first terminal, an authorization key based on a public key of a second terminal to obtain an authorization key ciphertext corresponding to the second terminal, and sending, by the first terminal, the authorization key ciphertext to the second terminal such that the second terminal decrypts the authorization key ciphertext based on a private key of the second terminal to obtain the authorization key, and then performs file decryption.

Abstract: A file access right authentication method and system allows right authentication to be performed on an access request for accessing a file in a system to thereby improve system security. The method includes: receiving, by an electronic device, a file access request, where the file access request is used to request to access a first file on the electronic device; obtaining a first process identifier in the file access request, and determining first fixed identity information corresponding to the first process identifier; and matching the first fixed identity information with authorized fixed identity information corresponding to the first file), and when the matching succeeds, determining that authentication of the file access request is successful.

Abstract: In an application management method, where when an application (APP) requests to invoke a system capability, an electronic device may determine whether a user is informed that the APP requests to invoke the system capability. If the user is informed that the APP requests to invoke the system capability, the electronic device may allow the APP to invoke the system capability. Otherwise, the electronic device may ask the user whether to agree with the APP to invoke the system capability, and allow the APP to invoke the system capability if the user agrees, or refuse to allow the APP to invoke the system capability if the user does not agree.

Abstract: This application provides a cross-device authentication method and an electronic device. The method is applied to a first electronic device. The first electronic device is connected to a second electronic device, and the method includes: The first electronic device receives a target operation performed by a user on a first interface of the first electronic device. The target operation is for triggering access to a first service, and the first service is associated with the second electronic device. The first electronic device obtains a target authentication manner corresponding to the target operation, and then the first electronic device acquires authentication information based on the target authentication manner, and sends an authentication request to the second electronic device. The authentication request includes the authentication information, the authentication request is for requesting the second electronic device to perform authentication on the first service, and the second electronic device generates an authentication result after performing authentication on the first service. The method is for implementing cross-device authentication information acquisition, to improve convenience of an authentication operation.

Abstract: An identity authentication method and a vehicle provide authentication of a user identity in a first authentication manner enabling permission to use a first function of the vehicle when the first authentication succeeds. The first authentication manner may include at least one of vehicle key authentication, password authentication, biological feature authentication, or connected device authentication. First driving data is collected and a second authentication is performed based on the first driving data. Permission to use the first function is disabled when the second authentication fails and is continued when the second authentication succeeds.

Abstract: The present technology relates to a file processing method. The file processing method can includes a first terminal device receiving an encrypted file from a second terminal device. The first terminal device stores the encrypted file. The first terminal device receives an access instruction for the encrypted file. The first terminal device obtains a current security state. When the current security state is higher than or equal to a first security state, the first terminal device decrypts the file by using a decryption key. It can be learned that according to the method, after the first terminal device receives the encrypted file, the first terminal device decrypts the file by using the decryption key only when a security state is high.

Abstract: A central control device identifies an identity of a user, and determines, based on the identity of the user, a smart home linkage solution associated with the identity of the user. Then, the central control device controls, based on the smart home linkage solution associated with the identity of the user, a public smart home device to enter a corresponding operating mode. When receiving a first operation of the user, the central control device controls, based on the smart home linkage solution associated with the identity of the user, the public smart home device to enter the corresponding operating mode.

Abstract: After a first device logs in to a first account in a first application, the first receives a first operation performed by a user on the first application. Login information of the first account includes the first account, or the first account and a login password of the first account. The first device displays, in response to the first operation, a first interface including one or more device options. Each device option corresponds to one wireless device found by the first device. The first device sends, in response to a selection operation performed by the user on a first device option on the first interface, identity information of the first application and the login information of the first account to a second device corresponding to the first device option.
