Description
Technical Field
The invention relates to the field of block chains, in particular to a safe and efficient block chain network customized login method and a safe reinforcement system.
Background
The big data era, the world wide has digitized and entered the sea of data via the internet. This not only makes our lives more convenient, but also provides opportunities for creating wealth. However, data security issues do not come in small amounts. Blockchains are expected to solve this problem in the future. The blockchain resembles an open network ledger. The method is originated from the bit currency and is the underlying technology of the bit currency, all information of transaction records can be packed into a 'block' for storage, and as the information exchange is expanded, the blocks are connected with each other to form a block chain. Digital currency, represented by bitcoin, is a point-to-point electronic cash system, and each transaction is broadcast to all participants in the network and is recorded into an account book after being confirmed for many times, which is a 'blockchain'. Each participant has an own account book, so that when false information occurs, the false information can be broken through mutual verification, and the network security is ensured. Each node in the blockchain is equal, a centralized management mechanism does not exist, the characteristic of decentralization enables the blockchain to be independent of a third party, the operation of the blockchain does not need any intervention of any person, and self-verification can be independently carried out. In addition, the network of the block chain is opened to the world, and any person can inquire data through the public port, so that the whole system is highly transparent, in short, the block chain is a credible database and a reliable 'account book', and all the applications can be realized in the aspects of cross-border payment, securities, loan, voting and the like in the future. For example, in cross-border payment, the block chain provides safety guarantee, remittance can be carried out to the whole world at any time and any place, and therefore many intermediate links and high handling fees are saved.
In general, a blockchain, Block Chain technology, is an emerging technology appearing in the field of financial technology (FinTech) in recent years, and has unique properties of decentralization, information non-falsification, multi-node collective maintainability, publicity, privacy protection and the like, and in an untrusted internet, transaction information data can be recorded and provided in a credible mode. The blockchain mainly comprises four components of a P2P network, cryptography, a consensus mechanism and an intelligent contract, unique characteristics of the blockchain are guaranteed through technical integration of the four fields, the blockchain technology is the only tool which can be used for recording and proving transaction consistency and company financial accuracy without a third party at present, requirements on audit effectiveness, accuracy and timeliness can be met, and the blockchain has a wide application prospect in the financial field. The technology will firstly impact the financial infrastructure of payment systems, security settlement systems, transaction databases etc., while also possibly extending further to general financial services such as credit systems, anti-money laundering etc.
However, in the current basic protocol of the block chain, taking a character string whose Key is 128 bits as an example, the following problems are caused due to the large number of bits:
1) the number of bits is large, which is not beneficial to customized login;
2) all stored on the data server, there is a security risk.
