Research And Application On Storage And Query Technology Of Currency Serial Number Based On Cloud Computing

With the development of our national economy,the scale of currency serial number data becomes bigger and bigger,and the transaction amount of information is also getting larger,leading to more higher requirement of data storage and query technology.Although some provinces in the domestic have conducted the management of currency serial number,they cannot provide a good experience to users due to the big currency serial number,complicated data processing,and long query time,thereby having an effect on the promotion of currency serial number management system and the supervision statistics for money.Cloud computing has changed the basic architecture of data storage,providing a new idea to manage the massive currency serial number data.Therefore,research on storage and query currency serial number based on cloud computing has important theoretical significance and practical value.This paper mainly includes the following two aspects:1.In order to solve the low memory property of the big currency serial number data,this paper optimizes the storage efficiency of currency serial number in cloud computing from the two aspects of collection and storage.According to the working process in the data bank,a kind of relational model is proposed during currency serial number acquisition upload process.It saves the cost of renovation for the bank ATM machine by the association between various processes rather than installing the capture module of currency serial number on the ATM machine to store currency serial number information.In terms of storage,an improved P-Ring algorithm is adopted to store various currency serial number data on the basis of the performance of nodes.By normalizing the parameters of nodes,it can optimize the storage performance of a currency serial number management system.Experimental results show that the P-Ring partition method improves the storage performance of currency serial number of cloud storage platform.2.In order to solve the low query efficiency and safety of the big currency serial number data,an exchange index binary search index-CEBS-Chord encryption is put forward based on the characteristics of the currency serial number.By encrypting the index and data,it optimizes query efficiency meanwhile ensures the safety of the currency serial number at the same time.The indexed not only enhances query efficiency but also reduces the storage space by using the binary search algorithm and transforming the character into a binary number in the terms of the characteristics of the currency serial number.Experimental results show that,compared with the current mainstream search methods,the query method with the CEBS-Chord index can improve the query efficiency and update efficiency,and it can meet the requirement of efficient query and safety of the currency serial number in the real world applications.
