The Design And Realization Of Security System For Foreign Loans Accounting Based On Work Flow

Modern countries always float loans to make up the shortage of funds and to accelerate the development of economy. After the opening up, both the central and local governments float more foreign loans than ever to promote the development of regional economy and social undertakings. The information work of foreign loan management is far from perfect because of the lack of systematic information process. It is an effective way to solve the problems by adopting new modeling and system development based on work flow management according to the long term and policy-sensitiveness of foreign loan management.Based on a thorough investigation of the foreign loan management in Hunan Province, this article discusses the main techniques of foreign loan management whose process is analyzed, refined and optimized by work flow modeling subsequently. Then it provides an accounting system for foreign loan management based on work flow to be used in the routine management of foreign loan, covering the application, approval and countersigning of foreign loan, as well as the making of repayment bill, approval, grant and collection of repayment. The system aims to help with the effective and standard operation of foreign loan management, recording in the database all the information about the grant and repayment of each loan, thus providing all kinds of information statistics and report forms to levels of financial departments as accurate basis for the decision-making on and analysis of the use of foreign loans.The article discusses the design and implementation of the accounting system for foreign loans according to standard workflow criterion. First, it introduces the background and research status of the management of foreign loan, reviewing the relative main techniques, followed by a detailed analysis of the financial management with the accounting system for foreign loan. Then it provides a system design scheme, including the analysis and design of database, HASH algorithm and function module. It also describes in detail the design and implementation of the major functions of the system. In the full use of the advantages of traditional Hash function based on indeterminate equation by introducing higher to increase the complexity of the iterative computation, designed a fixed256variable output hash Hash algorithm. By increasing the number of iterations of methods to improve the security of the algorithm. Compared with the traditional Hash function has the advantage of high complexity and better efficiency on Finally, it provides some test schemes for the system as well as an objective and comprehensive evaluation of it together with some suggestions for further improvement.
