The Frame Design On Iris Identification Software System

After the mankind steps into the 21st century, the requirement forinformation security is becoming stronger. Everybody is seeking a distinguishway which is more advanced, securer and swifter than key and securitypassword. Moreover, human body's biological character is taken as a methodto identify bodies for its unique, unchangeable and body-carry character. Thena new identification method--biological identification technology coming intobeing.This text is a design of the overall procedure on the Iris biologicalidentification system, as this kind of Iris-identify biological informationsecurity system just stepped into the initial period. The system-frame designanalyses through the whole procedure provide a solid plat form for thedeveloping Iris identification system. Through the analyses on the wholesystem, we divided the system to s five modules as: image collection, imageestimate, image pretreatment, characteristic denotation and character matchetc.Set up systematic frame based on the UML using for modeling of thebiological Iris identification system, also set up the frame on this basis. Firstly,make flow chart modeling on the system per request i.g. through thedescription and sign for the business procedure, frame procedure and dataprocedure, finish the flow chart on data and frame and the system framefunction chart.With systematic Iris identification flow chart, we can go on the detailanalyse and structuring on the system according to model. Use Case modelprovide service and make exchange through the confirmed system accordingto the customer's request. Among Use Case picture of the iris recognitionsystem, it represents division of the systematic function of software and everyUse Case products a valuable result through consider on content each UseCase represent so that we can set up the system function of softwarereasonable and convenience. The next step of Use Case model of the Iris identification system is to carryon the analysis and design of facing target, it regards use-case model asINPUT, make Use Case detailed to mutual between target and target in thisstage, the main analyzing picture draw with UML includes: type the pictures,order picture and activity picture, etc. Type picture function is to describevarious kinds of static relation, but order picture and activity picture modelingthe dynamic behavior and characteristic of system. Drawing of type picture isto finish function described by the Use Case, confirm system request andrealize one group attribute and service of target type of Use Case and alsoshowed the attribute, operation and restraint on the target connection. Orderchart of Iris Identification system show behavior order of Use Case, participateof mutual of one target of Use Case between the instances, have expressed therealization of the users'request that described in Use Case in detail. In theactivity picture, only pay attention to the result between the movement andmovement, the operation of an iris identification can be regarded as an activityand one activity can follow another. The identification of Iris is simply theorder relation. After the Analysis and statement at above-mentioned stages, proved thecomponent relation model, component technology can realize replying usingof software. Iris biological component of recognition system made up of 5models as: Picture gathering, assessment of picture, picture pretreatment,characteristic show and characteristic matched. Each component includesdifferent mode to realize the same functions. The make up the component ofthe same function together and the component has only offered the interfaceand method externally. Only understand outside interface component'srelation can you develop with the frame effectively and duplicated. The interface of the iris recognition system component is a kind of interconnectedinterface based on news, the component has been defined systematic responsibility on theexternal information transmission, component interface represents total mutual contentwith environment and only mutual way too. In addition, environment should not do anyother assumptions having nothing to do with interface to the component. Systematiccomponent carry on communication through news, interface defines the gather of thenews which component send out and received. News is information of the happening onsome identification. The news defined by the interface is divided into two kinds: (1) Newsthat component take place, notify system's other component of incident or ask service ofother component. (2) The news that the component receives, to the response of a certainincident or offer service to other components'request in the system. Each news in theinterface has defined a port of the component, the component with complementary portcan carry on communication through the news bus, The complementary port meanstwo ports that with same news'name, parameter and return result except thenews pass direction of the component. Once something happened, the systemor the component send out corresponding news, the news line is responsiblefor transmitting news to the component is interested in and realizes thedynamic connection. The interface of the Iris Identification system component is set up on thestructural design of the system, analyse and design the whole system structureon the basis of establishing the main member. Using C/S structure, analyse thewhole system and use the wrapped picture to divide the main function anddescribe each part's relation to confirm the main body relationship further. Onthe basis of the global structure design of the system, carry on its insidethinning, make analyses to show layer, logic layer (function layer) and datalayer. And combine the component, divided the related realizing environmentbetween the business logic with the whole idea of system and layered idea tothe system frame. This offer unified infrastructure to application softwaredeveloper, have offered and customized the expansion mechanism with logicbusiness datum, interface, function of the system and business flexibly, haveoffered a large amount o basic component and business course template can bereplayed.
