A method for detecting a video surveillance device includes: obtaining MAC address information and port information of at least one target device that accesses a same wireless network as the electronic device; determining, based on the MAC address information, whether the target device is a video surveillance device; if determining cannot be performed based on the MAC address information, determining, based on the port information or based on the MAC address information and the port information, whether the target device is a video surveillance device; and if determining still cannot be performed, obtaining fingerprint information of the target device by using a TCP port-based or UDP port-based probe protocol, and further determining, based on the fingerprint information, whether the target device is a video surveillance device.

Method for detecting video surveillance device, and electronic device

A capability enabling method and apparatus. A secure element (SE) establishes, with a trusted execution environment (TEE), a session for communication. The SE sends, to the TEE, an obtaining instruction to obtain a security certificate of the TEE. After receiving the obtaining instruction, the TEE generates the security certificate based on attribute information of the TEE, and sends the generated security certificate to the SE. After the SE receives the security certificate, the SE determines, based on the security certificate and a preset security policy, that the TEE is in a secure state. After the SE determines that the TEE is in the secure state, the SE enables a first capability for a third-party service in the SE based on a second capability of the TEE.

Capability enabling method and apparatus

An emulated card selection method is implemented on a mobile device having a near field communication (NEC) NFC function. A first emulated card and a second emulated card are configured on the mobile device, When detecting an NFC radio frequency field, the mobile device detects whether there is fingerprint input. The mobile device selects the first emulated card if there is the fingerprint input. The mobile device selects the second emulated card if there is no fingerprint input. The mobile device performs NEC interaction with the NFC card reader based on the selected first emulated card or second emulated card. The mobile device can automatically select an emulated card in different emulated cards based on a card swiping status when a user uses an NEC emulated card.

A fingerprint anti-counterfeiting method and an electronic device are provided. The fingerprint anti-counterfeiting method includes: After detecting a fingerprint input action of a user, an electronic device obtains a fingerprint image generated by the fingerprint input action, and obtains a vibration-sound signal generated by the fingerprint input action. The device determines, based on a fingerprint anti-counterfeiting model, whether the fingerprint input action is performed by a true finger. The fingerprint anti-counterfeiting model is a multi-dimensional network model obtained through learning based on fingerprint images for training and corresponding vibration-sound signals. The fingerprint anti-counterfeiting method in embodiments of this application helps improve a protection capability of the electronic device for a fake fingerprint attack.
