Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 1, a flowchart illustrating steps of a block chain based information storage method according to a first embodiment of the present invention is shown.

The block chain technology, bt (block chain technology) for short, also called as distributed book information technology, is an internet database technology, and is characterized by decentralization and public transparency, so that everyone can participate in database recording. The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system.

The blockchain encrypts transaction information in a transaction block through a hash algorithm and compresses the information into a hash string consisting of a string of numbers and letters. The hash value of the block chain can uniquely and accurately identify one block, any node in the block chain can obtain the hash value of the block through simple hash calculation, and the fact that the calculated hash value is not changed means that information in the block is not tampered.

The public chain refers to a block chain which can be read by anyone all over the world, can send a transaction, can effectively confirm the transaction, and can be used by anyone to participate in a consensus process, wherein the consensus process determines which block can be added into the block chain and simultaneously defines the current state. We can use the public chain to obtain the software version information, etc.

Private chain refers to a block chain whose write rights are only in one organization's hand, with the purpose of restricting read rights or open outside rights. The private chain has the following characteristics: 1. a small number of nodes in a very fast transaction speed private chain have a high degree of trust and do not require every node to validate a transaction. Thus, private chains trade much faster than public chains. 2. Data that provides better assurance for privacy of the private chain is not disclosed and is not available to all that own the network connection. 3. The transaction cost is greatly reduced even to zero and completely free or at least very cheap transactions can be made on the private chain. If a physical entity controls and processes all transactions, it no longer needs to charge a fee for the job. 4. Helping to protect its underlying product from damage. The use of private chains by operators/banks and traditional financial institutions can guarantee their existing benefits so that the original ecosystem is not destroyed. Through the private chain technology, an operator can realize self monitoring of whether the authentication approval user has access qualification.

The information storage method based on the block chain comprises the following steps:

Step 102: and when the identity information is matched with the authentication information, the sub-node is used as a lower node of the main node to access the block chain.

When the identity information such as the ID and PIN code of the child node mobile terminal is matched with the authentication information, the child node may be accessed to the block chain as a lower node of the master node through a network such as 4G/5G/WIFI.

Step 103: the method comprises the steps of obtaining first data information issued by a main node and initial data information of child nodes.

When the main node is an operator and the child node is a mobile terminal, the first data information issued by the operator and the initial data information of the mobile terminal can be acquired by executing the step.

Step 104: and when the first data information is different from the initial data information, writing the first data information into the child node to replace the initial data information.

Whether first data information issued by an operator is updated or not is checked, namely whether the first data information is the same as initial data information of the mobile terminal or not is checked, when the first data information is different from the initial data information, updating optimization is performed on the first data information, the mobile terminal obtains the first data information issued by the operator, and SIM card information of the mobile terminal is updated in time according to the first data information, namely the initial data information of the mobile terminal is replaced.

According to the information storage method based on the block chain, provided by the embodiment of the invention, when the identity information of the child node is matched with the authentication information issued by the main node, the child node is used as a lower node of the main node to access the block chain; and when the first data information issued by the master node in the block chain is different from the initial data information of the child node, the first data information issued by the master node may be written into the child node and replace the initial data information of the child node. By the block chain-based information storage method provided by the embodiment, the main node can control the SIM card information of the sub-node, and the information to be controlled is issued to the block chain, so that the SIM card information of the accessed sub-node can be conveniently and quickly updated, the cost of the entity SIM card can be reduced, and the safety and convenience of SIM card information storage and use can be enhanced.
