Disclosed are a method, system, and terminal for face-to-face loan signing, and a computer-readable storage medium. The method comprises the steps of: when a first terminal detects a face-to-face signing request, same acquires face-to-face signing information required in a face-to-face signing process and transmits the face-to-face signing information to a second terminal linked to the first terminal via a preset interface; when the second terminal receives the face-to-face signing information, same acquires identity information of a user corresponding to the face-to-face signing information and agreement information required in the face-to-face signing process; one seated at the second terminal is prompted to review the identity information and the agreement information to produce a review result; the review result and a prestored loan application form are transmitted to the first terminal; and the first terminal completes the face-to-face signing process on the basis of the loan application form and review result received. The present invention implements the connection of systems corresponding to the terminals involved in the face-to-face signing process, the user is only required to bring data required for the face-to-face singing to one designated terminal to complete face-to-face signing, thus increasing the efficiency of face-to-face signing.
A: A data examination and approval method, comprising: receiving a data application table acquisition request sent by a first terminal, the data application table acquisition request carrying a user identifier corresponding to the first terminal; acquiring examination and approval chains corresponding to the user identifier, and returning the examination and approval chains to the first terminal; receiving a filled-in data application table and a selected examination and approval chain which are returned by the first terminal; sending the filled-in data application table to a corresponding second terminal, and receiving a pre-examination result returned by the second terminal; 当预审结果表示预审通过时，则将数据申请表发送到与所选择的审批链对应的第三终端进行审批；	if the pre-examination result indicates that the pre-examination is passed, sending the data application table to third terminals corresponding to the selected examination and approval chain for examination and approval; if examination and approval results of the third terminals corresponding to the examination and approval chain all indicate that the examination and approval is passed, storing the user identifier and the data application table in an association manner, and marking the examination and approval result corresponding to the user identifier as passed.
B: Disclosed are a data interaction processing method, device and system. The method comprises: a first terminal sends requirement information for obtaining target data to a server, so that the server sends the requirement information to at least two second terminals, receives response information generated by the second terminals, and sends second terminal user information to the first terminal; the first terminal receives the second terminal user information, and sends a selection result regarding a second terminal user to the server so as to determine a target second terminal; the server sends an interaction request to the determined target second terminal; the target second terminal receives the interaction request, and sends target data matching the requirement information to the first terminal; the first terminal obtains the target data. The present invention enables the first terminal to select according to requirements a second terminal for target data interaction, thereby improving the flexibility of matching, and increasing the efficiency of a purchasing process.
C: Disclosed are a data transmission method, a terminal, a storage medium, and a processor. The method comprises: a first terminal sends a verification request to a second terminal, the verification request being used for verifying whether the second terminal and the first terminal are matched; in the case that the second terminal and the first terminal are matched, the first terminal acquires a first key sent by the second terminal; the first terminal encrypts user information stored in the first terminal using the first key; and the first terminal sends the encrypted user information to the second terminal so that the second terminal forwards a plaintext of the user information obtained after decryption to a third terminal, the third terminal processing the plaintext of the user information and then returning the processing result to the second terminal, the second terminal sending the returned processing result to the first terminal, and the first terminal receiving the processing result sent by the second terminal. The present invention solves the technical problem that the existing data transmission technology is low in transmission security.
D: Provided are a method and apparatus for determining a line of credit, a server and a readable storage medium, and the method is applied to a server. The method comprises: receiving a loan request of a user terminal; in response to the loan request, respectively auditing identity information, credit information and relationship information; and if the identity information, the credit information and the relationship information all pass the audit, determining a line of credit for the loan request based on the credit information and the relationship information. By means of the design, not only can the line of credit of a loaner be improved, but also the risk for a credit platform can be reduced.
