Abstract: Embodiments of this application disclose a noise reduction headset. A branch pipe is disposed in the headset to connect a sound cavity inside the headset and an external environment. The branch pipe has a low-pass filter function to filter out high-band noise entering the sound cavity from the external environment, so that impact on sound quality inside the sound cavity that is caused by noise in the external environment is reduced, thereby implementing passive noise reduction.

Abstract: A secured payment method, secured payment device and computer-readable storage medium, relating to the technical field of Internet. The method comprises: detecting whether a mobile terminal is connected to a first secured payment module, wherein the first secured payment module shares a payment hardware interface with the mobile terminal; activating the payment hardware interface, if the detection result shows that the mobile terminal is connected to the first secured payment module; detecting whether the payment hardware interface is controlled by the first secured payment module or by the mobile terminal; providing a payment warning, if the detection result shows that the payment hardware interface is controlled by the mobile terminal. Thus, the manufacturing costs of the devices can be reduced, potential safety risk in some transaction can also be avoided, and a secured payment is guaranteed.

Abstract: A secured payment method, secured payment device and computer-readable storage medium, relating to the technical field of Internet. The method includes: detecting whether a mobile terminal is connected; if the detection result shows that a mobile terminal is connected, activating a payment hardware interface shared with the mobile terminal; detecting whether the payment hardware interface is controlled by the secured payment device or by the mobile terminal during a payment process; if the detection result shows that the payment hardware interface is controlled by the mobile terminal, providing a payment warning. Thereby, the manufacturing cost of the devices can be reduced, also, potential safety risk in some transaction can be avoided, and a secured payment is guaranteed.

Abstract: A method for secure payment, including: detecting whether a connected mobile terminal exists; acquiring, when the connected mobile terminal exists, a first user transaction information, and encrypting the first user transaction information to generate a corresponding first encrypted transaction information; sending the first encrypted transaction information to a transaction verification server based on a first hardware interface of the mobile terminal, and receiving a transaction verification result from the transaction verification server; and determining, according to the transaction verification result, whether a payment operation is to be performed.

Abstract: A tamper-proof structure and an electronic device are provided in the present application. The tamper-proof structure includes a first-order circuit board, at least one tamper-proof component, at least one safety signal wire and a security chip. The safety signal wire is wrapped around an outer layer of the first-order circuit board or penetrates through a through hole and is wrapped around an inner layer of the first-order circuit board to form a tamper-proof area as required. The safety signal wire is connected to a tamper-proof switch and the security chip correspondingly, and a level of the safety signal wire is changed when the tamper-proof switch or the safety signal wire is damaged, and the security chip is triggered to erase sensitive information accordingly. By punching on the first-order circuit board, an objective of tamper-proof and an objective of reduction of design cost and simplification of security solution are achieved simultaneously.
