Problems solved by technology

However, since merchants with better reputation also pay attention to interests, in some cases, merchants with better reputation will also hide some bad information from consumers about the physical goods to be traded for the sake of interests. Concealed bad information, and will buy defective goods to be traded at a higher price, which damages the rights and interests of consumers

Embodiment 1

[0078] see figure 2 , which is a flow chart of the physical object information storage method provided by the first method embodiment of the present application.

[0079] The physical information storage method provided in the embodiment of the present application includes:

[0080] S201: Obtain the current digital fingerprint of the target object according to the received information storage request.

[0081] The specific implementation of this step will be described in detail below.

[0082] S202: When the information storage request is used to request to update the stored information of the target object, verify the ownership certificate obtained from the current digital fingerprint according to the user public key.

[0083] The specific implementation of this step will be described in detail below.

[0084] S203: When the ownership certificate passes the verification, send the old digital fingerprint verification request to the blockchain storage network, so that the b...

Embodiment approach

[0102] As an implementation manner, S302 may specifically be:

[0103] S302A1: Use the hash value corresponding to the old digital fingerprint, the hash value corresponding to the ownership certificate, and the hash value corresponding to each characteristic parameter as the hash value of a leaf node of the Merkle tree.

[0104] As an implementation, such as Figure 4 As shown, when the hash value corresponding to the old digital fingerprint is the old fingerprint hash value H 1 , the hash value corresponding to the ownership certificate is the ownership hash value H 2 , The hash value corresponding to the feature parameter is the first feature hash value H 3 To the Nth feature hash value H N+2 When, S302A1 can specifically be: the old fingerprint hash value H 1 , ownership hash value H 2 , the first feature hash value H 3 To the Nth feature hash value H N+2 They are respectively used as the hash values ​​of the 1st leaf node to the N+2th leaf node of the Merkle tree. ...

specific Embodiment approach

[0133] As a specific implementation manner, S202 may specifically be:

[0134] S2021: When the information storage request is used to request to update the stored information of the target object, obtain the ownership certificate according to the current digital fingerprint.

[0135] S2022: Obtain target characteristic parameters according to the ownership certificate and the user public key.

[0136] S2023: Determine whether the target feature parameter matches the feature parameter obtained from the current digital fingerprint, if yes, execute S2024; if not, execute S2025.

[0137] S2024: Determine that the ownership certificate passes the verification of the user public key.

[0138] S2025: Determine that the ownership certificate has not passed the verification of the user public key.

[0139] The above is the specific implementation of S202 provided by the embodiment of this application. In this implementation, first obtain the target characteristic parameters according...

Abstract

The invention discloses a real object information storage method and device and a real object information searching method and device, and the method comprises the steps of storing a current digital fingerprint which passes the verification of a user public key and the validity verification of a block chain storage network into the block chain storage network, and achieving the information storageof a target real object. The current digital fingerprint comprises the old digital fingerprint used for recording the historical information of the target object; Therefore, when the stored information in the block chain storage network is used for verifying whether the old digital fingerprint is valid or not; whether the current information change occurs on the stored information of the target object or not can be confirmed. Therefore, no information omission exists between the current digital fingerprint stored in the block chain storage network and the stored old digital fingerprint. Therefore, omission of change information of the target object is avoided, integrity of information storage of the target object is achieved, so that a subsequent user can accurately find all historical information of the target object, the user is prevented from being cheated due to the fact that the user does not know relevant information of the target object, and rights and interests of the user aremaintained.

Description

technical field [0001] The present application relates to the field of Internet technology, and in particular to a method and device for storing physical information, and a method and device for searching physical information. Background technique [0002] With the development of Internet technology, online transactions have gradually attracted attention. However, in the process of online transactions, for the sake of profit, merchants usually conceal some bad information about the goods to be traded from consumers, so as to deceive consumers into buying defective goods to be traded at high prices, which damages the rights and interests of consumers. [0003] For example, in the process of a used car transaction, in order to sell the target vehicle at a higher price, the seller concealed from the buyer that the target vehicle had a car accident, because the buyer cannot know the current target vehicle information. The target vehicle had a car accident, which caused the buye...
