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.
