For example, a banking institution builds a banking client APP through the alliance chain building module, when a user logs in the APP through a mobile phone, the user inputs biological characteristics such as a face through a camera on the mobile phone, and when the user needs to make a staged loan, the user sends out an application electronic contract to the APP, and the APP sends out identity authentication to the user.
After the user faces the face through the camera, the APP sends an electronic contract to the user; after a user reads an electronic contract for a period of time, the APP sends an electronic contract term confirmation to the user, and the electronic contract term confirmation highlights the electronic contract content, so that the user can watch the electronic contract conveniently; in response time, the user carries out electronic signature on the electronic contract clause confirmation, after the user reads clause voice confirmation, the user recites the contractor, then carries out second identity authentication, ensures consistency of the user before and after signing, ensures safety of the electronic contract, uploads the signed electronic contract, the electronic contract clause confirmation and the timestamp to the alliance chain, the timestamp is used as verification data to be tampered, other nodes in the alliance chain can check the electronic contract, and if the data is tampered, the other nodes can find tamper marks at the first time, so that safety of the data is ensured.
When a user needs to make an application for loan, in the signing process, the APP compares the handwritten signature with the signature in the staged loan, and when the handwritten signature is inconsistent with the signature in the staged loan, the APP secondarily sends the electronic contract clause to confirm and verify to the user so as to improve the attention of the user and facilitate the user to check the electronic contract.
The beneficial effects are that: (1) The nodes are corresponding to the biological characteristic information of the contractor, and the identity authentication module cannot change after uploading the identity authentication information, so that the credibility of each node is ensured.
(2) When signing, the contractor firstly performs identity verification on the contractor, ensures that the contractor operates by himself, and performs secondary verification on the identity of the contractor in the signing process, thereby ensuring the safety of electronic signing.

(4) The hash value and the electronic contract are integrated, so that the electronic contract is easy to find after being tampered, and the safety of the electronic contract is ensured.
The biological characteristics comprise fingerprints, faces and irises; the identity authentication information comprises personal or enterprise certificate information, biological characteristics of contractors, voice characteristics of contractors and electronic signatures or electronic chapters; the contractor comprises a contractor, a consulting party and a third verifying party.
The biological characteristics, the identity authentication information and the signing party provide an electronic basis for the electronic contract, so that the verification is convenient in the verification process; for example, during identity verification, the identity authentication module collects biological characteristics of the contractor through a camera, a receiver and the like on the mobile phone, so that the contractor authentication module can verify conveniently, and after signing, the biological characteristics are used as legal basis, so that legal rights and interests of the electronic contract can be improved and guaranteed.
The electronic contract term confirmation fails to include the contractor's question about the electronic contract and the response time out.
The two ways of the doubt and the overtime of the response time of the contractor to the electronic contract show that the contractor does not read or understand part of the terms of the electronic contract, and at the moment, the confirmation of the terms of the electronic contract does not pass, so that the objectivity of the electronic contract can be ensured, and the legal rights and interests of the contractor can also be ensured.

the touch display screen is used for displaying signing contents when a contractor signs a contract, receiving touch point position information of the contractor, sending the touch point position information to the CPU, and analyzing the touch point position information by the CPU;
when a contractor signs a contract for the first time, the touch display screen records the first touch point position information and the touch duration time of the contractor on the current interface after sensing that the contractor touches the touch display screen; if the change of the first touch point position information is smaller than a preset threshold value and the touch duration exceeds a preset waiting time, shielding the first touch point position information; then displaying a prompting signing instruction, recording second trigger point position information synchronously triggered by a contractor when the first touch point position information triggers, and forming a track when the second trigger point position information moves to obtain signing identity signing information; and if the change of the first touch point information is larger than a preset threshold value, recording the track when the first touch point moves, and obtaining sign information of the signed identity.
For example, in the conventional practice, when a customer takes a tablet to write with one hand, in order to ensure the stability of the tablet, the customer usually uses a palm to hold the bottom of the tablet, the thumb presses the edge of the screen or the screen, the thumb basically keeps still, but the screen recognizes the touch point of the thumb and displays the touch point in the signature area; according to the scheme, the touch point position information of the thumb pressed on the screen is shielded, so that a customer can clamp and fix a flat plate through the thumb, and the customer can carry out handwriting signature conveniently.
In other embodiments, the method may further improve, determine whether the first touch point is located at an edge position of the touch display screen (preset edge position information is obtained by comparison), and shield the first touch point information if the first touch point is located at the edge position of the touch display screen; then displaying a prompting signing instruction, recording second trigger point position information synchronously triggered by a contractor when the first touch point position information triggers, and forming a track when the second trigger point position information moves to obtain signing identity signing information; if the first touch point is not located at the edge of the touch display screen, recording the touch duration of the first touch point on the current interface, if the touch duration exceeds the preset waiting time, shielding the first touch point information, displaying a prompting signing instruction, recording second trigger point information synchronously triggered by a contractor when the first touch point information triggers, forming a track when the second trigger point information moves, and obtaining signing identity signing information; and if the touch duration is smaller than the preset waiting time, recording the track when the first touch point moves, and obtaining sign information of the signing identity.
The foregoing is merely exemplary of the present invention and the specific structures and/or characteristics of the present invention that are well known in the art have not been described in detail herein. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present invention, and these should also be considered as the scope of the present invention, which does not affect the effect of the implementation of the present invention and the utility of the patent. The protection scope of the present application shall be subject to the content of the claims, and the description of the specific embodiments and the like in the specification can be used for explaining the content of the claims.
