Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment 1 of the invention discloses an electronic contract signing method based on a alliance chain and biological characteristics, which comprises the following specific steps as shown in figure 1:
s1, deploying a block chain complete node to an electronic contract service related party, and constructing an electronic signed alliance chain;
s2, uploading the identity authentication information of the electronic contract service related party to a alliance chain;
s3, identifying the signatory through biological characteristics, and uploading a handwritten signature or an electronic seal to an electronic signing system to complete electronic signing;
and S4, uploading the signed electronic contract, the PDF-hash and the timestamp to a alliance chain.
The block chain has three different application modes, and the public chain refers to the block chain which can be used by anyone to read data and initiate transaction in the system at any time; a federation chain refers to a block chain in which a plurality of organizations participate in management together; the private chain is that all the participating nodes are strictly controlled to be specific. The public chain, the alliance chain and the private chain have different environment trust degrees, tampering difficulties and service processing efficiencies. The alliance chain mode is the main direction of application in the fields of industry and enterprise; the transaction on the alliance chain is verified only by a plurality of trusted nodes, low delay and high efficiency of the transaction are guaranteed, only specific members issued with permission can participate in accounting authority and maintenance management, the identity of participants is verified from the source, mutual trust is enhanced, and block chain safety is guaranteed.
The block chain is a distributed system formed by a plurality of nodes which are communicated with each other; while a federation chain is a block chain for inter-enterprises. The alliance chain only aims at members of a specific group and limited third parties, a plurality of preselected nodes are internally designated as bookers, and generation of each block is jointly determined by all the preselected nodes.
The PDF-hash is a unique value obtained by calculating PDF synthesized by the electronic contract through a hash algorithm. And the same file is subjected to hash algorithm to calculate the same value for each time. The hash value may change with any type of change to the file or signature.
In this embodiment, as shown in fig. 1, a block chain complete node is deployed to an electronic contract service related party, and an electronic signed federation chain is jointly constructed. And uploading the identity authentication information of the electronic contract service related party to the alliance chain to complete identity authentication. The identity authentication information comprises personal and institution certificate information, signed human biological characteristics, handwritten signatures or electronic stamps and the like.
Furthermore, the electronic contract service related parties comprise signing parties, consulting parties, verifying parties and other related parties; the biological characteristics comprise biological characteristic information of biological identification such as fingerprints, human faces, irises, finger arteries and the like.
The time stamp mainly has the function of verifying whether data is tampered, and the time when a certain data is generated is authenticated through technical means so as to determine whether the data is tampered after being generated. The time stamp is the total number of seconds from greenwich time 1970, 01, 00 hours 00 minutes 00 seconds (beijing time 1970, 01, 08 hours 00 seconds) to the present. Colloquially, a timestamp is a complete verifiable piece of data that can indicate that a piece of data already exists at a particular point in time. The time stamp is proposed to provide the user with an electronic proof to prove the generation time of some data of the user. The time stamp server of the embodiment adopts an authoritative time source, and the accurate time for generating the electronic file can be determined through the trusted time stamp.
Furthermore, the invention can be widely applied to a plurality of document signing links of insurance application, receipt of insurance policy, renewal payment, insurance, claim settlement and the like in the insurance industry. At present, the cost of the universal standard 0.1 yuan/time in the electronic signature industry is calculated, and the insurance company costs nearly million expenses every year; the federation chain and biometric-based de-intermediation electronic contract signing method can help the expenditure to gradually reduce to 0.
For example: the method is applied to the insurance industry, and comprises the following specific steps:
the method comprises the following steps: deploying a block chain complete node to an electronic contract service related party, constructing an electronic signed alliance chain, and adding an insurance company into the alliance chain to form a node mechanism on the chain;
step two: in the document signing link, a client needs to perform face living body detection on a mobile terminal APP of the insurance company;
step three: after the detection is passed, the client carries out handwritten signature, the mobile terminal submits the collected user identity authentication information, handwritten signature picture and document PDF file to an electronic signature platform, and the electronic signature platform synthesizes the handwritten signature and the PDF;
step four: and uploading the signed electronic contract, the PDF-hash and the timestamp to a alliance chain through the insurance company node.
Step five: the bank insurance monitoring party is used as a monitoring organization to join the alliance chain, so that monitoring responsibilities can be more conveniently performed, and credible data can be acquired in real time; and if a judicial organization joins a alliance chain, and disputes occur in links such as claim settlement, insurance refunding and the like, the evidence obtaining process becomes simple, and extra time is not needed to be spent for verifying the authenticity of the evidence.
The embodiment 2 of the invention discloses an electronic contract signing system based on a alliance chain and biological characteristics, which comprises an alliance chain construction module, an identity authentication module, a signing module and a chain linking module, as shown in figure 2; wherein the content of the first and second substances,
the alliance chain building module is used for deploying the block chain complete node to the electronic contract service related party and building an electronic signed alliance chain;
