Abstract: This specification describes techniques for processing service requests. One example method includes receiving an electronic credential request from a client, retrieving an electronic credential that corresponds to the user identifier, generating server signature information, and transmitting the server signature information and the electronic credential to the client. The server signature information includes the electronic credential and a user public key of the client. The electronic credential and the user public are signed using a server private key. The server signature information is configured to be cryptographically verified by the client and configured to enable the client to generate a two-dimensional barcode based on the electronic credential. The electronic credential included in the two-dimensional barcode is configured to be verified by a credential verification device. The credential verification end device is configured to generate the electronic credential based on the user identifier.

Abstract: This specification describes techniques for processing service requests. An electronic credential request including a user identifier is received from a client. An electronic credential that corresponds to the user identifier and a user public key that corresponds to the user are retrieved. A hash operation is performed on the user public key and the electronic credential by using a hash algorithm to obtain a hash value that is signed within a predetermined time period. Server signature information is generated using the hashed credential, and transmitted with the electronic credential to the client. The server signature information is cryptographically verifiable by the client and enables the client to generate a two-dimensional barcode based on the electronic credential.

Abstract: The present application discloses example methods and systems. In one example method, sound wave information associated with a data transmission is monitored within a predetermined distance from the client device, where the sound wave information including predetermined security information. In response to detecting sound wave information associated with a data transmission, the sound wave information is parsed to obtain the predetermined security information included in the detected sound wave information. Pattern information is generated based on the predetermined security information and data information to be sent. The generated pattern information is then displayed so that a second device can obtain the generated pattern information.

Abstract: Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for data synchronization. One of the methods includes that a first terminal device establishes a data channel to a specified carrier through near field communication. The first terminal device obtains an account identifier of a first account and first streaming data corresponding to the first account through the data channel, where the account identifier of the first account and the first streaming data are stored in the specified carrier. The first terminal device determines second streaming data corresponding to a second account associated with the first account, and performs data synchronization between the first account and the second account based on the first streaming data and the second streaming data.

Abstract: This specification techniques for sharing service and identity information between devices. One example method include acquiring, by a first device, a digital object identifier (DOI) of a second device, the DOI including identity information associated with the second device; generating, by the first device, a service DOI based on the identity information from the DOI of the second device, the service DOI including the identity information of the second device and service information; and displaying, by the first device, the service DOI on a display of the first device, wherein the displayed service DOI is configured to cause the second device to perform service processing when the displayed service DOI is acquired by the second device, and wherein the service processing is based at least in part on the identity information and the service information included in the service DOI.

Abstract: A digital object identifier (DOI) display request is received. A service type of a service corresponding to the display request is determined. Basic user information of a first user and identity type information corresponding to the service type is determined based on the service type and stored calibration information, where the identity type information is pre-authenticated to ensure validity based on a validity period associated with the identity type information. A DOI of the first user is generated based on the basic user information and the identity type information. The DOI is displayed for a second user to perform service processing based on the basic user information and the identity type information in the DOI.
