Abstract: A blockchain-based electronic signature method includes: receiving an electronic signature authentication request sent by an electronic signature client, wherein the electronic signature client is bound to one or more legal signature users, and the electronic signature authentication request includes biometric information of a signature user collected by the electronic signature client; in response to the electronic signature authentication request, authenticating whether the signature user is a legal signature user bound to the electronic signature client based on the biometric information; and if yes, returning an authentication result to the electronic signature client, so that the electronic signature client further prompts the signature user to perform an electronic signature operation in response to the authentication result; and receiving an electronic signature submitted by the signature user and collected by the electronic signature client, and publishing the electronic signature to a blockchain.

Abstract: Methods, systems, and computer-readable storage media for generation of a unified view of the graphical user interface. Implementations include actions of receiving, from a server, structured data of an interface template that is generated by the server by parsing interface template data associated with the interface template. The interface template is identified based on an interface identifier included in the service data. A virtual view node for the widget is determined based on the structured data. The widget is retrieved based on the location information associated with the virtual view node. A unified view of the graphical user interface is generated by rendering the widget with a plurality of widgets associated with the graphical user interface and is displayed on a display device.

Abstract: A method for pushing information in live streaming is provided. With this method, a live streaming terminal may send a push information identifier to a live streaming server in a live streaming process. The live streaming server may determine an access address of push information based on the push information identifier, and send the access address to a play terminal. The play terminal can present the push information to a play terminal user, and allows the play terminal user to trigger the access address. When the play terminal user triggers the access address, the play terminal can access a web page corresponding to the push information. As such, an access address of push information published by a live streaming terminal user can be accessed on an interface of a play terminal, and a user of the play terminal can obtain the push information by clicking the access address.

Abstract: A business process starting method, which is applied to a terminal and includes: acquiring multimedia data, the multimedia data carrying image data of a predetermined scenario, and uploading the multimedia data to a server; receiving business entry information returned by the server, wherein the server maintains a correspondence between standard image information of predetermined scenarios and business entry information, and the returned business entry information corresponds to standard image information matching the uploaded image data; and starting a business process based on the business entry information. The technical solution of the present application starts a corresponding business process by using a predetermined scenario that is easy to distinguish, thereby avoiding a wrong business process caused by the scanning of a wrong two-dimensional code, and increasing the security of a business while improving user experience.

Abstract: This invention discloses an information pushing method. The method includes receiving, by a live streaming server in a live streaming process, a push information identifier from a live streaming terminal; determining an access address of the push information based on the push information identifier; and pushing the access address to a play terminal for presentation. When the play terminal detects that the access address is triggered by a play terminal user, the play terminal accesses a web page corresponding to the push information.
