In this embodiment, NFR is a unique digital asset equity casting technology based on a block chain technology, and is implemented by converting the author of a picture and the content attribute information of the picture into byte bytes, obtaining a hash value-digital ID through hash calculation, and storing the digital ID and the attribute of the picture on a block chain.
Specifically, casting a digital stamp collection by blockchain and NFR techniques includes the following:
1. production of digital ID:
when a digital stamp is made into an NFR, we need to extract its basic information: the author of the picture, the picture content properties including size, color, etc., convert this information into byte bytes, and then input the bytes into an encryption algorithm to get an output value. A hash value is obtained through hash calculation, each hash value uniquely corresponds to a source content based on the uniqueness and the anti-collision property of the hash algorithm, and the hash values cannot be easily tampered. This hash value is the digitized intermediate-digital ID of the picture.
2. ID certification:
and carrying out intelligent contract development on the blockchain, wherein the intelligent contract directly maps the basic properties and the circulation mode of the NFR which is manufactured by us. And deploying the developed intelligent contracts to the block chains selected by us. And calling the developed intelligent contract, and storing the digital ID and the attribute of the picture on the block chain.
3. NFR work display:
when the picture information is stored in the block chain, a certification ID is obtained, through the ID, the user can go to a developed intelligent contract to read the data of the picture NFR information, at the moment, the user can obtain a URL, and through the URL, the user can restore the content of the cast digital stamp collection work stored in the IPFS distributed file system through a browser or other medium application.
The personal account module includes: the system comprises an order module, a use module, a collection module, a gifting module and a conversion module;
the order module is used for the individual user to place an order to purchase the selected digital stamp collection, and the order module can select payment, pending payment or canceling the order and the like. After a personal user logs in the system, the user can select a favorite digital stamp collection on a main page of the system, click to purchase an order, and pay and purchase the digital stamp collection directly through payment modes such as a bound payment treasure or WeChat, and the like, and can pay or cancel the order at a later time.
And the use module is used for attaching the digital signature of the digital stamp to the mail in various forms after the individual user uses the authorized signature based on the block chain when the mail is sent, and the post office verifies the digital signature of the digital stamp, verifies the use right of the corresponding stamp NFR and adds a digital stamp to fulfill the mail sending obligation. In this embodiment, the various forms mainly include printing to mails, binding online, and the like in offline reality.
And (3) a digital signature verification process: firstly, generating a signed digital stamp, then using a Hash algorithm to make a digital abstract for the digital stamp, and then using a signature private key to asymmetrically encrypt the digital abstract, namely making a digital signature; then the signature, the digital stamp original text and the public key of the signature certificate are added together for packaging to form a signature result which is sent to a post office to be verified. The post office receives the result of the digital signature, which includes the digital signature, the digital stamp, and the user public key, i.e., the data to be verified. The post office carries out signature verification, and the specific process is as follows: the post office verifies the digital signature by the public key of the individual user to derive the digital abstract, and carries out the same Hash algorithm on the original text of the digital stamp to obtain a new digital abstract, and compares the results of the Hash values of the two abstracts to verify the same signature, otherwise, the signature is invalid.
The collection module is used for displaying various digital stamp collections paid and purchased by an individual user;
the transfer module is used for the individual user to transfer the collected digital stamp collections to other people and also can receive the digital stamp collections of other people; specifically, a referral module is arranged on a personal account page, after the referral module enters the personal account page, the referral module clicks to refer, a block chain address of a referral party is input, then a personal account referral password is input, and the referral function can be realized after confirmation.
