【摘要】：按照国家的有关文件精神，各地市都成立了相应的产权交易中心机构负责对企业国有产权转让的各种受理，监督和管理，产权交易分交易申请，交易受理，信息挂牌，查询洽谈，进行交易，签订合同，结算交割，产权过户等工作流程，而在这些工作流程中需要企业提交许多相关材料和证件的复印件，要通过到固定场所进行洽谈交易，这些工作给企业和受让方都带来了许多不便，往往双方都需要跑很多部门上交许多材料进行各种审批，这种传统的模式效率十分低，因此专门设计了《产权交易中心综合管理网络系统》，这套系统实现了产权转让企业的网上用户名申请，产权交易中心交易部对用户进行注册授权，产权转让企业对将提出申请的各种材料进行网上电子提交和各种证件的网上在线拍照，产权交易中心对提出产权转让申请的企业进行挂牌授权，对企业的各种资料进行网上发布，通过网络进行洽谈和竞拍，产权交易中心财务部对交易进行各种结算，同时还设计了各种统计和打印功能，实现了产权交易中心的各种业务的网络信息化管理，提高了交易和管理效率。系统中的关键技术 1、WEB页面利用网络摄像头拍照技术解决证件副本传输问题本系统中设计有企业国有产权转让时，通过网络提交各种审核材料，这些审核材料都是电子稿提交，提交时可以是WORD文档，在需要提交某些证件的复印件时提供了两种方式，一种是可以用扫描仪进行扫描，然后提交扫描图片文档的方式，另一种方式则是采用了利用用户端的摄像头对证件进行拍照并生成图片电子文件然后通过系统进行上传的办法，这种办法更加方便用户的使用，但这种方式如果是在C/S结构中是比较容易实现的，但在B/S结构中，则在WEB页面中操作摄像头就比较困难，在WEB页面中操作摄像头有几种方式，常见的有采用WEB插件的方式来进行操作，但这种方式需要软件插件的第三方公司支持，可能还需要支付一定的费用，另一种方式是采用最新的HTML5代码来编写网页文件，这种方式比较容易，但是需要用户端的浏览器支持，因为目前支持HTML5的浏览器太少，因此本系统不适用这种方式，而还有一种方式就是采用在WEB页面中嵌入FLASH的办法，然后利用FLASH的可编程机制在FLASH中进行动作编程来实现对摄像头的各种控制，这种方式既不需要第三方支持也不需要使用特殊的浏览器，因此这是非常适合本系统使用的方式，目前系统中使用的就是这种FLASH的解决方案。 2、密码输入WEB页面软键盘输入技术目前有许多病毒和木马程序它们侵入用户计算机后通过监控用户键盘的输入信息来盗取用户的输入的各种密码，因此在本系统中的各种用户的输入密码登录系统的操作中采用WEB软键盘的技术来防止这些程序对用户键盘输入密码的监控和盗取，保证了用户使用的安全性，在C/S结构中设计软键盘是比较容易的，但在B/S结构中设计软件盘是比较复杂的，在设计的时候通过编写HTML和JS代码来进行实现。 3、网页页面在线洽谈技术本系统中为了方便企业国有产权转让方和受让方能够不受时间地点的限制，因此考虑到了充分利用网络环境的办法，设计了一个WEB在线洽谈功能，企业国有产权转让方和受让方可以同时登录到这界面进行WEB在线洽谈，洽谈时支持文字，图片的传输，同时支持文本样式修改，屏幕抖动和语音传输等功能。 4、WEB页面报表打印技术对于一套管理系统报表的打印是非常重要的，而在C/S结构下设计报表比较容易，但在B/S结构中设计报表就比较困难，如果选用VS2008.NET自带的水晶报表进行设计虽然功能强大，设计起来也容易，但需要付费注册，因此本系统采用的是专门的报表控件来进行设计，尤其是在产权交易中心财务部打印结算发票时设计出了精美的发票进行WEB打印输出。 5、WEB页面CSS和DIV技术 CSS和DIV技术是近年来兴起并应用较多的一种网页页面布局排版的两种技术，而本系统中许多地方将这两种技术进行结合使用，CSS是网页设计中的一种样式表技术，它可以设计单独的样式表文件也可以直接放入到当前的WEB页面中，，但设计单独的CSS样式表文件可以使许多WEB页面都能够进行调用，因此采用这种方式的设计效率会更高，它是将WEB页面中的许多元素的排版样式进行定义，然后在WEB页面中的相应元素的位置进行调用就实现了元素的排版，这样做既合理又高效，DIV是WEB页面中的一种层技术，它可以独立定义某些元素为一个整体然后可以设定隐藏和显示，用这种技术更有利于WEB页面元素的复杂排版，本系统的许多WEB页面就是采用这两种技术相结合的办法实现的复杂排版。 6、WEB页面登录验证码技术目前有许多黑客程序具有利用数据字典采用穷举法对WEB登录页面进行注入式攻击，因此系统中采用了图片显示的数字验证码的方式来防止这种攻击，同时为了防止黑客程序的OCR识别技术，每次刷新之后显示的验证码都是随机改变的，这样有效的保证了用户登录的安全性。 7、WEB服务器USB加密狗技术为了保护系统的设计版权，如果采用注册码的方式往往可以被破解，因此采用了当今比较流行的USB加密狗技术，这种加密狗安装在服务器上，整个系统由于也安装在服务器上，所以有效的保证了系统的知识产权，如果系统安装在没有USB软件狗的服务器上就不能运行，USB加密狗采用了厂商提供的API驱动接口程序，然后在本系统的相应模块中进行调用从而实现了加密过程。
[Abstract]:According to the national spirit of the relevant documents, around the city have set up all kinds of property rights trading center the institutions responsible for the transfer of state-owned property right to accept the supervision and management of property transactions, transaction application transactions handled, listing information, query transactions, negotiation, contract, settlement, transfer of property rights in the work process, and this process needs to copy many companies to submit related materials and documents, to negotiate transactions through to a fixed place, the work for the enterprise and the transferee has brought a lot of inconvenience, often on both sides need to run many departments on many materials for a variety of approval, the traditional mode of efficiency is very low, so special the design of "integrated network management system of property rights trading center", this system has realized the enterprise property rights transfer online name for transactions of property transactions in the heart of the user The registration authority, the enterprise property rights transfer online electronic submission and various documents online for various materials will apply the pictures, property rights trading center of the enterprises listed on the transfer of property rights to apply for authorization, a variety of enterprise information online publishing, negotiate and auction through the network, financial department property trading center for settlement the deal, while a variety of statistics and print function design, implementation of network information management business of property rights trading center, trading and improve management efficiency.
Key technologies in the system
1, WEB page uses the camera technology of webcam to solve the problem of document copy transmission
This system is designed with the transfer of state-owned property rights of enterprises, submit various audit materials through the network, the audit materials are submitted to submit the electronic version, is the WORD document, submit copies of some documents to provide two ways, one is can be scanned using a scanner, and then submit the document scanning pictures by the way, another way is used to take pictures of documents and pictures generated electronic documents using a client to the camera and then through the system to upload, use this method more convenient for users, but this way if it is in the C/S structure is relatively easy to implement, but in B/S, then the operation of the camera in the WEB page is more difficult, in the WEB page camera operation in several ways, there is a common way to use WEB plug-in operation, but this approach requires software plug-in The third party company support, may also need to pay a fee, the other way is using the latest HTML5 code to write web documents, this way is relatively easy, but requires the user browser support, because the current browser support for HTML5 is too small, so the system does not apply to this way, and there is a the way is used in the WEB page into the FLASH, and then use the programmable FLASH mechanism to achieve a variety of camera motion control programming in FLASH in this way does not require third party support also do not need to use special browser, so it is very suitable for the use of this system, the current system this is the use of FLASH solutions.
2, password input WEB page soft keyboard input technology
The password input information to steal users there are many viruses and Trojans invade their users computer by monitoring user keyboard input, so the password system of various users in the system in the operation of using WEB soft keyboard technique to prevent and monitor these programs to steal user keyboard input password and to ensure the safety of users, in the C/S structure design of soft keyboard is relatively easy, but in the B/S structure design software disk is more complicated, when the design by using HTML and JS code to implement.
3, web page online negotiation technology
In this system, in order to facilitate the enterprise state-owned property rights transfer and the transferee can not limited by time and place, thus taking into account the full use of the network environment, the design of a WEB online discussion, party the state-owned property rights transfer and the transferee can login to the WEB interface of the online discussion, support text talks image transmission, text style, modify and support, screen jitter and voice transmission and other functions.
4, report printing technology of WEB page
It is very important for a management system of report, and the report is easier to design in the C/S structure, but the design statements in the B/S structure is more difficult, if the choice of VS2008.NET comes with the crystal report design is powerful, it is also easy to design, but need to pay the registration, so this system is used in special the report controls to the design, especially in the financial department printing property trading center invoice when designing exquisite invoice print WEB output.
5, WEB pages CSS and DIV Technology
CSS and DIV are two kinds of technology of a web page layout in recent years and widely used, and many places in the system of these two technologies combined with CSS is a stylesheet technology in web design, it can design a separate style sheet file can also be directly into the current the WEB page, but the design of separate CSS style sheet file can make many WEB pages can be invoked, so the design efficiency of this way will be higher, it is the definition of many elements in the WEB page layout style, then the corresponding elements in the WEB page in the location of the call is realized elements of the layout, it is both reasonable and efficient, DIV is the WEB page in a layer of technology, it can be defined independently of certain elements as a whole can then be set to hide and display, this technology is more advantageous to WEB The complex typesetting of page elements, many WEB pages of this system are complex typesetting implemented with the combination of these two techniques.
6, WEB page login verification code technology
There are many hackers program is using the data dictionary of WEB login page injection attacks using exhaustive method, the system adopts the image display digital verification code to prevent such attacks, at the same time in order to prevent hackers OCR recognition program, each new brush displayed after verification code is randomly changed, so to effectively guarantee the security of user login.
7, WEB server USB encrypted dog technology
In order to design a copyright protection system, if the registration code often can be cracked, so the use of today's popular USB dongle, the dongle installed on the server, because the whole system is also installed in the server, so the effective guarantee system of intellectual property rights, if not installed in the USB software system the dog can not run on the server, the USB dongle manufacturers to provide the API driver interface program, and then call to realize the encryption process in the corresponding module of this system.
