This paper presents an improvised approach for plain text password encryption in the server's database. One of the major aspect of password protection issue is to secure it by means of encryption process. In cryptanalysis, a dictionary attacks or brute force attacks are the most common ways of cracking passwords. A new approach for improvising the scheme of password encryption is using the process of Jumbling-Salting (JS). In order to augment the security aspect regarding passwords, we are devising JS algorithm which prevents dictionary and brute force attacks by increasing the length of cipher text in a considerable limit. In this algorithm, the jumbling process selects characters from pre-defined character set and adding them into the plain password using mathematical modulus (%) function;salting comprises of adding a random string into jumbled password. Ultimately AES block is implemented which obtains a fixed length password which is stored in the server's database. Randomized version of JS algorithm ensures that there is increase in time to crack the cipher text password, by forming a highly secured version of encrypted password.

The improved Coastal Cliffs Morphology Analysis (CCMORPH v2.0) Toolbox offers multiple python scripts designed for streamlining the processes of generating, analyzing, and comparing the morphology of coastal cliffs. It is comprised of a simple, user-friendly, and flexible workflow that uses existing open-source code for processing coastal 3D data and plotting geospatial information. The upgraded toolbox exhibits significant improvements in the methodologies employed to delineate cliff bottom and top points. Moreover, this version covers the automatic comparison of the coastal morphology features directly on the input Digital Elevation Models or on selected coastal profiles. The tool holds immense potential to eliminate the difficulties in automation that often deter oceanographers and coastal geoscientists, thereby facilitating the widespread adoption of automation tools for monitoring and analyzing a broader spectrum of coastal environments.
我国居民生活水平的提升使得居民投保意愿和投保数量也随之上升,进而使得近几年我国保险行业发展迅速。尽管居民投保意识有所增加,但各保险企业仍然需要对投保客户进行资源争夺,在争夺过程中保险企业的客户管理等将和产品起到决定性作用。因此能够快速、高效、多途径让投保客户了解保险产品成为有效途径。本论文在综合阐述保险业务办理流程的基础上,并依据本系统所划分的预期用户:系统管理员、投保客户(潜在投保客户)、保险公司业务人员(保险公司销售人员),总结了本系统的六个主要设计目标,根据可行性分析表明本系统具备一定的可行性。进而为实现本系统的设计目标,进行了系统功能性需求分析及功能设计、系统非功能性需求分析。在系统功能性需求分析及功能设计中,针对系统管理员、投保客户、保险公司业务人员这三类用户在系统操作中可能产生的需求,为满足上述操作需求,本文将系统主要功能总结为:系统用户登录、系统用户管理、投保客户信息管理、保险产品信息管理、投保单管理、投保合同信息管理等,并对各个总功能进行了详细划分,通过各主要功能实现对保险产品、投保单、投保客户等信息的管理(添加、查询、修改等)。基于需求分析和功能设计,将系统模块详细划分为七个功能模块,包括了系统登录模块、投保单管理模块等,在各功能模块设计中详细介绍各子功能的主要操作、实现流程图、操作时序图。为实现本系统,在系统设计基础上进行系统架构设计,采用了经典三层架构(表示层UILayer、业务逻辑层BLLayer、数据访问层DALayer)。本系统的数据库设计涵盖数据库概念结构设计和数据表设计,通过梳理各实体间的依赖关系,总结本系统的总体E-R图,详细设计了包含系统管理员信息表、投保客户信息表等六个信息实体表。依托B/S模式、java script、JSP等,采用Microsoft SQL Server 2005作为系统数据开发工具,实现了本系统的各功能。保险公司客户管理系统通过客户管理、保险产品管理等功能有利于对客户信息进行集中管理,多途径进行保险产品详细信息的查询,投保单和投保合同的线上录入、查询等,将有效提升业务员工作效率。同时从单元测试和集成测试两个方面进行了系统测试,并给出了主要测试用例的测试结果图,测试结果表明系统具备操作性。
