摘要： Embodiments of this specification disclose an offline transaction processing method, apparatus, and device. The method is applied to a first terminal of a transaction initiator. The method includes the following: Information about a current network connection status of the first terminal is obtained for a target transaction; if the current network connection status of the first terminal is connected, and it is determined that a network connection status of a second terminal of a transaction target party of the target transaction is unconnected, or the current network connection status of the first terminal is unconnected, it is determined whether the first terminal can output a transaction identification code used to trigger offline transaction processing on the target transaction; and an offline transaction policy corresponding to a determining result is selected based on the determining result indicating whether the first terminal can output the transaction identification code, and offline transaction processing is performed on the target transaction between the second terminal based on the selected offline transaction policy.

摘要： This disclosure relates to a method and a system for recognizing a disguised device. A client of an application is installed on the device for interacting with the application, and the method includes: receiving environment information associated with the device and a device ID associated with the device in response to an interaction with the application from the device; determining whether the device ID exists in a prestored association table of a unique environment identifier and a device ID; and if the device ID does not exist in the association table, calculating a unique environment identifier associated with the device based on the environment information; searching the association table for a device ID associated with the unique environment identifier by using the unique environment identifier; and determining, based on a quantity of different identified device IDs associated with the unique environment identifier, whether the device is disguised.

摘要： Some embodiments of this specification provide data processing methods, apparatuses, and devices. The method includes: establishing a secure channel with a terminal device based on the same channel establishment rule as that of a secure element of the terminal device; sending a service key and an identifier of the service key to the terminal device through the secure channel; receiving a key identifier of a target service key, service ciphertext information, and a service session key ciphertext sent by the terminal device; determining the target service key based on the key identifier of the target service key, obtaining a service session key based on the target service key and the service session key ciphertext, and obtaining service data of a target service based on the service session key and the service ciphertext information so as to perform service processing on the target service based on the service data of the target service.

摘要： Embodiments of this specification provide a payment service implementation method and apparatus. According to the method in the embodiments, when a payment service is performed, anonymous processing needs to be performed on original payment account information. First, a random number is used to perform transform processing on the original payment account information, so that information encrypted each time by using a public key is different. Then, the public key and an encryption algorithm obtained in advance are used to encrypt payment account information obtained after the transform processing, so as to obtain anonymous payment account information, thereby completing an anonymous processing process. After anonymous processing is completed, the obtained anonymous payment account information may be used to perform a payment operation.

摘要： Embodiments of this specification disclose a resource transfer method, apparatus, and device. The method includes the following steps: A resource transfer request triggered by a target user by using a target application is obtained, where the resource transfer request includes verification information used to perform resource transfer processing and identity feature information of the target user; then, the verification information can be verified by using the target application, and if the verification succeeds, a local device management rule is invoked by using the target application, and it is determined, by using the device management rule, whether the identity feature information of the target user matches identity feature information of a pre-registered user; and the resource transfer request is sent to a first server corresponding to the target application if the identity feature information of the target user matches the identity feature information of the pre-registered user, to trigger the first server to perform resource transfer processing based on the resource transfer request.

摘要： Some embodiments of this specification provide data processing methods, apparatuses, and devices. The method includes: acquiring a running state of a target application in a trusted execution environment; if it is determined that the target application runs abnormally in the trusted execution environment based on the running state, acquiring a first key and a device key, and debugging information, generated in the trusted execution environment, corresponding to the target application in the trusted execution environment, where the device key is a key generated by a server based on a client device; encrypting the debugging information based on the first key in the trusted execution environment to obtain encrypted debugging information, and encrypting the first key based on the device key to obtain an encrypted first key; and sending the encrypted debugging information and the encrypted first key to the server.
