However, it also makes the intellectual property rights of information not effectively protected. In order to build the data security mechanism in WebGIS based on tile caches and B/S architecture, this paper analyzed the potential data security problem in some main WebGIS from three aspects: client-code scripting, transmission of vector data and request of attribute information. The scripts usually records the calling methods of tile caches with plaintext, which makes the algorithm open and may leak the organizing structure of the tile caches; The transmission way of the vector data is included in the scripts that executed in the Browser, which makes it easy to download them from server side to client side; All the attribute information in WebGIS are classified and usually can be obtained through malicious request continuously. It also presented the corresponding measures of enhancing security mechanism, such as information hiding, digital watermarking, vector data encryption and request information restrictions. Furthermore, this paper gives the implementation of encrypting the http request and vector data using JavaScript program language. The empirical results show that these measures can avoid the data leakage and protect the data copyright effectively. The study is of special importance from the theoretical and applicative points of view.","PeriodicalId":267621,"journal":{"name":"2009 International Conference on Management and Service Science","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121234690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is generally acknowledged that intangibles such as knowledge now lead to firms being more flexible and thus more competitive. To understand the development of competitive advantage, we must understand knowledge especially tacit knowledge and how it is shared. Therefore, based on review of critical literatures, the author first summarizes current views of the definitions of knowledge to six perspectives and classifies views of tacit knowledge to four types. This paper aimed to set a theoretical foundation for studies on the sharing of tacit knowledge in organizations. The author found that there are two different views on sharing tacit knowledge due to the conceptual differences of it. Then the author investigate the difficulty of sharing tacit knowledge and found that the difficulties in the externalizing and sharing of tacit knowledge are linked to perception, language, time, value and distance. Among which, perception and language are the main difficulties in sharing tacit knowledge.","PeriodicalId":267621,"journal":{"name":"2009 International Conference on Management and Service Science","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125149965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
