Instead of sitting on a chair and playing with a controller, real walking gives the most natural experience when exploring the virtual world. However, considering both physiology and psychology factors, there are several challenges to achieve high fidelity when walking in a VR world with massive multimedia data. That is, the isometrical mapping is not feasible in most cases, as the real space can be completely different from the virtual world (usually smaller). Moreover, the sound is usually not consistent with visual cues when considering the directions. Therefore in this paper, we present a VR walking system that contains a huge virtual campus with extensive multimedia data, which combines 3D models, animations and stereo sound. To this end, we adopt a VR redirected walking method for the purpose of perception manipulation, and HRTF-based sound system for audio-visual consistency. By wearing a head-mounted display and walking in a small room tracked by our indoor localization algorithm, the user is able to freely explore the whole VR world with high fidelity.","PeriodicalId":430283,"journal":{"name":"Proceedings of the 3rd International Conference on Cryptography, Security and Privacy","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126245322","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}

Graphical-based password techniques have been proposed as a potential alternative to resolve security and usability limitations. However, most of the existing graphical password schemes like PassMatrix are vulnerable to random guess attacks based on hot-spot analyzing whereas some pass-images are relatively easier to guess because they are more memorable, obvious or unique. To overcome this problem, the researchers proposed the Jumbled PassSteps method. By replacing the single discretized image of the PassMatrix method into several independent images and applying a random grid traversal method, attackers cannot easily guess the original pass-image of the user even if they observed the log-in session. Because the acquisition of the one-time grid traversal steps is done with the use of earphones, the direction and number of traversals to be done in a particular session cannot be acquired by attacker even if it is camera recorded. Experimental results show that Jumbled PassSteps effectively overcomes hotspot guessing attacks and achieves better resistance to shoulder-surfing attacks.","PeriodicalId":430283,"journal":{"name":"Proceedings of the 3rd International Conference on Cryptography, Security and Privacy","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128316255","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 method constructs a database of face-image patches with their positions from example images of normalized faces. Given a low-resolution (LR) image, the method generates an SR image by finding similar patches in the database and incorporating high-frequency component of the patches to the LR image. Since the method just divides an example image into patches, for example, 5x5 patches in five-pixels intervals, the SR process may misses the chance to have the patch of the finest position. The proposed method generates patches in one-pixel intervals to increase the chance. In order to cope with the massively increased size of the patch database, the proposed method restricts the area to search the patch candidates for each position. An experimental result shows the proposed method achieves better results than the previous in term of the peak signal-to-noise ratio (PSNR). Furthermore, the proposed method has reduced computational time by 90% compared to the previous.","PeriodicalId":430283,"journal":{"name":"Proceedings of the 3rd International Conference on Cryptography, Security and Privacy","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131240096","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 deadend phenomenon (also known as the \"local maximum\" problem) poses major difficulties when performing geographic forwarding in wireless sensor network since whenever a packet encounters a dead-end, additional overheads must be paid to forward the packet to the destination via alternative route. In this paper, the proposed algorithm route the data packets around the connectivity holes region. The proposed algorithm consists of two phases; the detection of dead node is performed in first phase, avoidance of connectivity holes and selection of forwarding nodes are performed in second phase of algorithm. The residual energy, packet delivery ratio and distance are considered while selecting forwarding nodes. The proposed algorithm ensures that the data packets are forwarded in an energy efficient manner and improves PDR. Through extensive experiments shows that our algorithm performs better than the existing Protocol [10] in terms of energy consumption, network life time, packet delivery ratio and energy consumed per packet.","PeriodicalId":430283,"journal":{"name":"Proceedings of the 3rd International Conference on Cryptography, Security and Privacy","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126375410","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}

Despite their ease of use, user authentication is an important factor that must be taken into consideration. In addition to the use of passwords, biometric data such as fingerprints or iris images can also be included as part of a multi-factor authentication system. However, these methods require secure storage of the biometric template and active participation from the user. In this paper, we propose a new method of authentication for identification cards based on colour visual cryptography and facial recognition. A colour image of the user will be encrypted using visual cryptography and split into two share images, one of which will be stored on the database and the other will be stored in the card. When the card is placed onto a sensor, the two shares will overlap to uncover the original image. The recovered image is then fed into a trained facial recognition algorithm to verify the user's identity. The proposed method is evaluated based on recognition rate and runtime. Experimental results indicate the feasibility of the proposed method for practical application and can be used as a starting point for future work in the area.","PeriodicalId":430283,"journal":{"name":"Proceedings of the 3rd International Conference on Cryptography, Security and Privacy","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115177390","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}
