Mattsson","doi":"10.1109/ICECT.2005.9","DOIUrl":"https://doi.org/10.1109/ICECT.2005.9","url":null,"abstract":"Security is becoming one of the most urgent challenges in database research and industry, and there has also been increasing interest in the problem of building accurate data mining models over aggregate data, while protecting privacy at the level of individual records. Instead of building walls around servers or hard drives, a protective layer of encryption is provided around specific sensitive data items or objects. This prevents outside attacks as well as infiltration from within the server itself. This also allows the security administrator to define which data stored in databases are sensitive and thereby focusing the protection only on the sensitive data, which in turn minimizes the delays or burdens on the system that may occur from other bulk encryption methods. Encryption can provide strong security for data at rest, but developing a database encryption strategy must take many factors into consideration. We present column-level database encryption as the only solution that is capable of protecting against external and internal threats, and at the same time meeting all regulatory requirements. We use the key concepts of security dictionary, type transparent cryptography and propose solutions on how to transparently store and search encrypted database fields. Different stored data encryption strategies are outlined, so you can decide the best practice for each situation, and each individual field in your database, to handle different security and operating requirements. Application code and database schemas are sensitive to changes in the data type and data length, the paper presents a policy driven solution that allows transparent data level encryption that does not change the data field type or length.","PeriodicalId":312957,"journal":{"name":"Seventh IEEE International Conference on E-Commerce Technology (CEC'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133649504","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}

Common forms of prevention are copy-protection techniques based on physical tokens. While physical tokens provide better protection from unauthorized copying than intangible ones, the protected digital content becomes unsuitable for online distribution. This paper investigates the role of copy-protection techniques based on physical and intangible tokens in software piracy prevention. An internationally organized online survey among users of sequencer software, a particular kind of music software, provides the data for the subsequent descriptive analysis and logistic regression. Based on our findings, we present the general implications of our results for a software publisher's anti-piracy and online distribution policy.","PeriodicalId":312957,"journal":{"name":"Seventh IEEE International Conference on E-Commerce Technology (CEC'05)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128251318","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}

A business process is modeled by using a new visual tool named activity-control diagram (AC diagram). Frequently occurring business procedures are captured by the adoptions of reusable workflow patterns. With formally defined semantics using distributed system theory of happens-before ordering, process behavior can be mechanically analyzed at design time. A completely specified model is automatically converted to a workflow by an iterative traversal algorithm that maps an AC diagram to an XML workflow specification. The spec can then be executed by an XML workflow engine to facilitate cross enterprise ecommerce applications.","PeriodicalId":312957,"journal":{"name":"Seventh IEEE International Conference on E-Commerce Technology (CEC'05)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130847105","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}

These manual steps are tedious and may cause security faults. In this paper, we present an automatic electronic contract document signing system in a secure environment. The system comprises a document and signature profile module, a signing text template module and a signing information superimposed module. The document and signature profile module parses the contract document and signature information. Based on this information, the signing text template module creates a signing text template with empty text fields. The signing information superimposed module carry out a novel electronic document signing method. This novel method consists of four processing steps: inserting signing text data into empty text fields, converting the text template into an image template, adding signing image data onto the image template, and superimposing the signing image template on the contract document to produce a signed electronic contract document. This automation system has found to improve substantially the efficiency, and at the same time eliminate the potential for human errors and security breaches in signing electronic contract documents.","PeriodicalId":312957,"journal":{"name":"Seventh IEEE International Conference on E-Commerce Technology (CEC'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125393440","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}

Profiles for interoperability between MPEG-21 REL and OMA DRM MPEG-21 REL和OMA DRM之间互操作性的概要文件

A clear example is at the level of rights expression languages (RELs), where two of them are competing to have a place in the market. On the one hand, MPEG-21 REL is an ISO/IEC official standard, and on the other hand ODRL (open digital rights language) is a REL initiative that has been adopted by the open mobile alliance (OMA), a relevant industrial forum in the area of mobile systems. MPEG-21 REL is more complete, but rather complex; this is why ODRL could be considered in some cases as a more flexible option. In this paper, we analyse a DRM specification from OMA, and try to propose its implementation in an MPEG-21 environment. By defining an MPEG-21 REL DTD and a subset of the MPEG-21 REL authorisation model we are in fact specifying an MPEG-21 REL profile. This approach could simplify the implementation of MPEG-21 REL applications. In order to verify the feasibility of our proposal, we have also implemented some tools that work with both MPEG-21 REL and OMA DRM.","PeriodicalId":312957,"journal":{"name":"Seventh IEEE International Conference on E-Commerce Technology (CEC'05)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121224832","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}
