Abstract: A composite solution for enhancing induced disease resistance of lentinan (LNT) to a plant, a preparation method of the composite solution, and a method for enhancing induced disease resistance of LNT to a plant are provided. The composite solution for enhancing induced disease resistance of LNT to a plant includes: an LNT-containing solution and an SPc-containing solution, where SPc is a dendritic macromolecule functionalized by an amino functional group, and has a structural formula shown in formula I, where n=1 to 100. An LNT/SPc complex is produced in the composite solution. SPc spontaneously combines with LNT through hydrogen bonding, such that an agglomerate structure formed by LNT in an aqueous solution is broken and reduced to a nano-scale particle size, and a spherical particle is produced, which can significantly reduce a contact angle of the LNT aqueous solution, and promote the distribution and diffusion of LNT.

Abstract: A face image of a resource transferor is obtained, wherein the face image is used to authenticate an identity of the resource transferor. Resource transfer identification information of the resource transferor is obtained, wherein the resource transfer identification information corresponds to a transferor account of the resource transferor. Based on the resource transfer identification information, information about the transferor account and a reference image corresponding to the transferor account are obtained. In response to determining that the face image corresponds to the reference image, a resource of the resource transferor is transferred based on the information about the transferor account.

Abstract: A security question generation instruction is sent by a server to a user device. A reference picture is received at the server from the user device, where the reference picture is generated by the user device based on the security question generation instruction. A number of confusion pictures corresponding to the reference picture are determined by the server. A security question is generated by the server based on the reference picture and the plurality of confusion pictures.
