Description
Technical Field
The invention relates to a seal informatization technology, a digital encryption, decryption and authentication technology, a mobile internet/internet of things information analysis and management technology, a data analysis technology, a block chain technology and a cloud storage/computing technology, in particular to an intelligent seal and an intelligent seal service system which is established in a cloud server and is based on the block chain technology.
Background
At present, the examination and approval and the manufacture of official seals realize informatization management, the use of the official seals is still a traditional mode, the effectiveness of the official seals is determined by a mode of comparing imprint patterns printed by the official seals each time with reserved seal patterns, and the authentication mode only depends on visual comparison and cannot realize intellectualization; the comparison results are only relatively approximate and cannot be accurate. Accordingly, how to achieve accurate comparison, the existing technical information and patent literature disclose that many people with kernel and people with intelligence have the published technical scheme. For example, a patent with application number 2011103391075 and name "seal system and seal" proposes a seal informatization scheme, which combines a seal and an RFID electronic tag into an electronic seal impression, writes signature information into the electronic seal impression, uploads the signature information to a server for storage management and downloads the signature information to a client for verification, and realizes informatization, network management and verification application of the seal use process. For another example, a patent application with application number 2014105083918 entitled "a mobile online tracking verification electronic intelligent seal, an electronic seal management system and a verification method" proposes a scheme of combining a mobile internet technology, a CA digital authentication technology, a non-contact RFID tag reading and writing technology and a traditional seal body (photosensitive seal, rubber offset print, penetrating seal and the like), realizes the real-time verification of the seal use based on the electronic seal, uses the time, the place and the print of the seal as the complete information of the acquired seal, and provides the application of multi-point verification during the verification of the electronic seal. For another example, a patent application with application number 2014105037483 entitled seal informatization device, electronic seal management system and authentication method for off-line use on-line authentication proposes a seal use verification system based on electronic seal in off-line state by using the CA authentication technology based on PKI system.
However, only with the above examples of analysis, there are problems to be improved: firstly, the above invention identifies the authenticity of prints based on post-verification logic, i.e. false or illegal prints may have been generated, and the above system provides reliable, non-repudiatable evidence by technical means to verify the authenticity of existing prints. Also, the drawback of post-verification logic is that while the system can provide strong evidence to assist in arbitration or legal processes where false or illegal imprints cause disputes, in many cases actual damage has already been caused because a false or illegal print has already been generated. The system is therefore not able to effectively control the damage that has occurred. Secondly, the verification mechanisms of the invention all need the electronic seal as an information carrier, and the seal user needs to pay attention to the preparation of the blank electronic seal all the time, so that the seal management system based on the electronic seal is not very effective for individuals with frequent seal use, individuals with unavailable blank seal or individuals with very sensitive seal cost. Therefore, it is a lesson to be done currently in the industry to overcome the defects of the prior art and provide industry standards for the same industry.

In a typical contract signing service, a blockchain record is equivalent to an account specifically including a party A and a party B, a programmable part of a blockchain is defined through service definition, and when corresponding operation is performed, an electronic intelligent seal enters a corresponding process according to the programmable part, and if the electronic intelligent seal is signed with the other party, a two-dimensional code needs to be scanned to obtain a public key of the other party and then the seal operation is performed.
The seal management module in the figure records enterprise real name information and seal management information approved by a public security department, writes seal information into a manufactured seal through the seal management processing module of the client, writes service definition information corresponding to the seal into the seal, generates a secret key, writes the seal into the seal through a wired port and a seal management processing function corresponding to the inside of the seal, receives related data through seal management processing, and automatically cuts off a network communication part of the seal through a cold wallet control module circuit, ensures that the writing period is not on line, and ensures the safety of the related information, particularly the secret key.
When the seal is used, every time of stamping, a service is selected, if not, the self-signing service is defaulted (only the account number of a user is recorded), the stamping sensor module in the online control electronic seal is combined with the time of a client, a processing module is set through the service of the seal, an operation flow is entered, and data is generated by a stamping data generation module in the online control electronic seal, wherein typical stamping data comprises the account number of the user, the account number of the opposite side and the service type. After the seal is stamped, the network connection is cut off through the cold wallet control module circuit, the private key is read, the signature is carried out, and the stamping record of each time is stored through the data storage processing module.
The seal judges the electric quantity through a power management module in the seal automatic control unit, if the electric quantity is enough, the use data is uploaded in real time through an online transmission module, otherwise, after a low-electric-quantity state is reported through a network, a black box mode is entered, the seal displays that charging is needed, low-power consumption operation is maintained, only the seal data is recorded, uploading is not performed, and after the sufficient electric quantity is charged, the network is communicated, and the stored data is uploaded.
And a using data module in the seal automatic control unit is added into a data pool to be packaged after being identified by the timestamp server (each using data is uniquely identified).
When the seal is idle, the accounting module in the blockchain unit automatically acquires data to be packed from the data pool waiting for packing (only data which is not issued by the accounting module can be acquired, and third-party packing is performed), records the data in the blockchain data module, and uploads the data to the blockchain node server.
When a plurality of blockchain node servers pass through a point-to-point synchronization mode, all blockchain data are synchronized, and a blockchain recording process is completed.
Extracting specific types of services in a block chain by a service query module in the seal automatic control system for query; and by using the query module, after the query condition is set, the specific stamping data is queried.
