Description
Technical Field
The invention relates to the technical field of block chain terminal equipment, in particular to block chain terminal equipment based on cryptography and a control method thereof.
Background
The block chain technology is a non-responsible person distributed accounting data basic technology system developed for recording encrypted currency transaction details such as bitcoin and the like. The blockchain is a distributed data system with nodes participating in, has the characteristic of being unchangeable and unforgeable, and can also be understood as an 'account book' system. It consists of a series of data blocks generated using cryptographic amplification, each block containing the hash value of the previous block, connected to the current block starting from the starting block, forming a chain of blocks, referred to as simply a chain of blocks. In short, the blockchain is a technical basis, which is called an "account book" for short, and then the virtual currency is an application function in the account book.
From the perspective of consumers, the consumers are most worried about purchasing inferior commodities in the consuming process, and the consumers can track the inferior commodities more and trace the origin and production source of the commodities except the whole express delivery and payment process, so that the doubt in consuming can be solved. virtual currency is also a financial instrument, and as with traditional currency, they also have a law of currency value. The circulation rule of the virtual currency is also called as a currency demand rule, is different from the traditional currency, and the commodity circulation process of a country in a certain period needs to be in direct proportion to the total amount of commodities. Otherwise the phenomenon of inflation and deflation of the currency will occur.
The block chain is predicted to be a technology which is likely to significantly change the world after agricultural technology, industrial technology and information technology, and the omnibearing influence on the world is profound. Because the intelligent block chain breaks through the centralized concept, people can assist in reasonably doing things for the first time by using the intelligent contract with the technology, the efficiency is greatly improved, and the block chain is more people-oriented than any technology in the philosophy level.
the foundation of digital virtual currency is generated based on block chain technology, which is also called as distributed account book technology, and its characteristic is decentralization and distrust, the principle of block chain technology is to find out the person who is fast and good in account in a period of time, and then to send the information of account book to other person in the system, which is equivalent to change the record of database of all nodes in the whole network, and for bit currency, the ownership of bit currency is recorded by the distributed account book, and through encryption protocol, it has the characteristics of non-falsification and encryption security, so it can also ensure the property security of both sides of transaction. The security of the digital virtual currency, which is the most concerned by all users, is the security of the digital virtual currency, which is stored in a pure digital form, with the identity information code and private key as the proof of ownership, so that these items are stored on a relatively secure storage device. With the continuous progress of the block chain technology, the problem of security of virtual currency is well solved, and digital currency becomes a future development trend on the premise of great development of global economy.
The block chain technology is developed earlier than the bitcoin, but the bitcoin is popular with people, many people invest and trade the bitcoin, and at present, many places accept bitcoin payment, although bitcoin is not legal currency, bitcoin lays a good foundation for the future era of digital currency, and with the development of bit currency, many countries also begin to research digital currency, national people's banks also begin to research digital currency, and the comprehensive application of digital currency still needs to be established on various technical bases such as whole network information recording, credit real-time calculation, whole people network integrity, bottom layer technical safety, currency legal authorization, and algorithm indecipherable, and needs a certain time for realizing the technical bases, and the generalization of the digital currency is also beneficial to citizens to pay attention to self credit, the service quality of financial service is improved, and the healthy development of internet finance can be promoted.
The terminal equipment of the prior art generally adopts traditional data encryption mode, cause data to lose very easily, and, prior art's terminal equipment generally need not carry out authentication just can operate terminal equipment, terminal equipment's security has been reduced, moreover, current terminal equipment's display screen does not shelter from the thing, expose for a long time, the dust easily covers on the display screen, influence the display effect of display screen, terminal equipment's practicality has been reduced, and general terminal equipment does not shelter from the thing, when operating, the information is easily seen by people around, lead to information leakage, terminal equipment's security has been reduced.
