Our network model is between 3 parties, the game producer, the game distributor and the game player (client), where we aim to support the distributor to fight against cheater clients with minimum cooperation from the game producer. Our protection system is centered on our specifically designed module, GameGuard, which accomplishes the main protection duties while simultaneously, interacts with the GameClient program so that if a serious hack attempt is detected, both will terminate. Our two layers of protection, in hiding game modules and detecting hacks, integrated with the mechanism of auto-updating/reporting with the distributor server provide a general, powerful yet flexible approach in building hack protection products. We support the game distributors with a general protection framework which is not dependent of specific games and also only need minimum cooperation from the distant game producers. Our approach is powerful enough that we would defeat most kinds of attacks which are based on hooking Windows APIs, including ones from memory, graphic or hardware attack categories. Our GameGuard system is also robust against attacks directed at the protection modules: we achieve authenticity of our protection modules based on the authenticity of the GameClient assured by the producer. Based on our framework, we have implemented a hack protection system which is being extensively experimented at VTC, the Vietnam Multimedia Corporation, with very encouraging results.","PeriodicalId":388053,"journal":{"name":"Proceedings of the 1st Symposium on Information and Communication Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128066696","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}

In our approach, we define the concept of linguistic cluster center by employing the semantic structure of hedge algebra. This kind of cluster center is constructed to give the appropriate weights for each pattern of the dataset in our clustering algorithm. The parameters of hedge algbra are then optimized in the training process to obtain the suitable parameters for the dataset. We also incorporate the k-means algorithm to get better results in comparing to conventional FCM.","PeriodicalId":388053,"journal":{"name":"Proceedings of the 1st Symposium on Information and Communication Technology","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127041626","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}

The most difficult problem in the non-intrusive system of eye gaze tracking is the problem of head movements. Some of existing methods have to use two cameras and an active infrared (IR) illumination to solve this problem. Otherwise, with a single camera, the user has to hold the head uncomfortably still when performing a session of eye gaze tracking. If the head of the user moves away from original position, the accuracy of these eye gaze-tracking systems drops dramatically. In this paper, we propose a solution using Gaussian Processes for eye gaze tracking that allows free head movements with a single camera.","PeriodicalId":388053,"journal":{"name":"Proceedings of the 1st Symposium on Information and Communication Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123420681","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}

Many approaches have been proposed for fingerprint matching such as minutiae point pattern-based techniques, orientation pattern-based techniques, ridge-based techniques, global and local features combination-based techniques (GLF-BCT). In recent research, GLF-BCT methods achieved good performance even when a large portion of fingerprints in the database are of poor quality. In this paper, we would like to improve the GLF-BCT model using Genetic Algorithm (GA) that we aim to achieve higher efficiency in fingerprint recognition. In detail, the proposed model is a combination of the advantage of local minutiae descriptors (ability of increasing the distinctiveness degree between two different fingerprint images) with the advantage of the global features (identifying the optimal or near optimal global alignment between two fingerprints) to improve the reliability of GA fitness assignment in fingerprint matching. This method is called the Fingerprint Matching based on Combining Global features and Local minutiae Descriptors in Genetic Algorithms (FM-CGLD-GA). The experimental results on the FVC2004 database show the effectiveness and superiority of the proposed method in comparing to other approaches.","PeriodicalId":388053,"journal":{"name":"Proceedings of the 1st Symposium on Information and Communication Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131644138","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}

The purpose of this paper is to take some initial steps towards methodically normalizing input text in Vietnamese for a TTS system. This paper proposes a categorization and a normalization model for Vietnamese text based on related results for other languages. An experimental application is implemented to demonstrate the model, which uses several techniques including letter language model and decision trees for classifying NSWs and both supervised and unsupervised approaches for expanding abbreviations.","PeriodicalId":388053,"journal":{"name":"Proceedings of the 1st Symposium on Information and Communication Technology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133862377","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}

We investigate whether we can deploy an electronic-health application on top of an ad hoc peer to peer network. The initial prototype shows that it is feasible.
