Computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems for generating proof of payment. One computer-implemented method includes: verifying user information of a plurality of users of a service on a terminal device, wherein the service starts from a start location and ends at an end location, the user information comprises a quantity of the plurality of users, the plurality of users comprise an owner of a service account associated with the service to be paid for by using the terminal device and at least one companion selected by the owner; and in response to the user information of at least the owner is verified, generating at least one proof of payment based on the user information and account information of the service account, wherein the at least one proof of payment is verified at the start location and the end location.

Implementations of this disclosure provide blockchain-based virtual resource allocation. An example method performed by a node device of a blockchain network that operates as an intellectual property management platform includes receiving a target transaction comprising (i) a first quantity of virtual resources for obtaining intellectual property rights for a target object, (ii) an identifier of the target object, and (iii) an identifier of the intellectual property rights, and invoking a smart contract to (i) allocate the first quantity of virtual resources to obtain intellectual property rights for the target object, and (ii) allocate a second quantity of virtual resources to a beneficiary of the intellectual property rights for the target object.

Blockchain-based virtual resource allocation

The present disclosure discloses a method and device for identity authentication. One example method includes retrieving stored fingerprint information for a user including a plurality of recorded fingerprints for the user, each recorded fingerprint associated with a different finger of the user; selecting a subset of the recorded fingerprints to be used to authenticate the user; prompting the user to provide fingerprint information corresponding to each finger associated with a recorded fingerprint in the selected subset; in response to prompting the user, receiving user-provided fingerprint information from the user; matching the user-provided fingerprint information against the selected subset of the recorded fingerprints; and determining that an identity authentication of the user succeeds when the user-provided fingerprint information matches the selected subset of the recorded fingerprints.

Method and device for identity authentication

This disclosure relates to blockchain-based copyright distribution. In one aspect, a method includes receiving, by a node device of a blockchain network, a target transaction including design data of a target work and an identity of a target copyright user corresponding to the target work. Design similarity comparison logic and copyright distribution logic are executed. The design data of the target work is compared with the design data of the existing work stored in the first smart contract to obtain a target similarity between the target work and the existing work. A copyright for the target work is distributed between the target copyright user and a copyright user corresponding to the existing work based on the target similarity. Copyright distribution data that specifies distribution of the copyright between the target copyright user and the copyright user corresponding to the existing work is stored in the first smart contract.

Blockchain-based copyright distribution

At a first computing device, a target image is identified. The target image is provided in a display on the first computing device in a communication area displaying a conversation between a first user using the first computing device and a second user using a second computing device. An indication is received that the first user has initiated editing of the target image. An edit control listing editing options is provided for display in the communication area. At the first computing device, a user selection is received of a particular editing option selected from the editing options. An edited target image is created by editing the target image using an edit operation associated with the particular editing option. The edited target image is provided to the second computing device and the communication area is updated to display the edited target image.

Instant-messaging-based picture sending method and device

A user interface is provided for display by a computing device. The user interface provides a graphical display of an application executable by the computing device. The computing device receives information provided by a user to the application through the user interface. The computing device analyzes the information provided by the user, where the analyzing includes: identifying one or more keywords of the information provided by the user; comparing the one or more keywords with a keyword library, the keyword library indicating computer-related services; based on the comparing, and identifying a particular computer-related service. The computing device provides a function interface of the particular computer-related service for display on the user interface.
