In this system, a user can prove relations on his/her attributes embedded into the certificate. Previously, we have proposed an anonymous credential system with constant-size proofs and faster proof generations for CNF formulas than the existing system. In the system, in the verification, some value should be included in some set Φ. Unfortunately, this system has a problem of requiring long public parameters that is proportional to the size of the set Φ. In this paper, we propose an extension to reduce the public key by separating this set Φ into two sets Φ<sub>1</sub> and Φ<sub>2</sub> with logarithmic sizes such that u<sub>1</sub> ϵ Φ<sub>1</sub> and u<sub>2</sub> ϵΦ<sub>2</sub> if and only if u<sub>1</sub> + u<sub>2</sub> ϵ Φ. Furthermore, we evaluate the efficiency based on the implementation.","PeriodicalId":294532,"journal":{"name":"2013 IEEE 2nd Global Conference on Consumer Electronics (GCCE)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127134692","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}

DPR is a technology where a portion of the entire circuit is replaced with another one, while the other parts of the circuit still continue running. Using DPR, different functionalities are not necessarily implemented at once; only required modules need be implemented on the FPGA. Therefore, a DPR system requires less hardware resources, and consequently, can save the power consumption of the system. We explored the effectiveness of DPR in saving energy and area of a multi-algorithm cryptoprocessor on Kintex-7 FPGA on SASEBO-GIII board. The cryptoprocessor supports the six ISO/IEC 18033-3 block cipher algorithms: AES, Camellia, SEED, TDEA, MISTY1, and CAST-128. In a DPR cryptoprocessor, only one cipher module is implemented at once, and it is overwritten when a different algorithm is required. Compared to the non-DPR cryptoprocessor, the DPR cryptoprocessor can reduce up to 74% hardware resource (slice) and 3.4% energy consumption.","PeriodicalId":294532,"journal":{"name":"2013 IEEE 2nd Global Conference on Consumer Electronics (GCCE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126401329","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}

One application of Body-Braille is the Helen Keller Phone system which is a communication system for deaf-blind people. It is currently in the commercial stage. Since it is expected that users of Body-Braille will increase in number, a self-learning system for Body-Braille is required. Moreover, such a self-learning system must be easy for deaf-blind users to use. In this paper, we describe a wireless device which we have developed for this purpose and details of a self-learning system for Body-Braille. In order to test the system, we performed an experiment in which 14 subjects recognized Body-braille patterns in the first stage of self-learning. The recognition rate was 74.1%. However, post-experiment interviews revealed a keystroke issue that if corrected, would yield a 92.0% recognition rate.","PeriodicalId":294532,"journal":{"name":"2013 IEEE 2nd Global Conference on Consumer Electronics (GCCE)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115164993","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}

Users have only to capture a short video of the target object to realize matching to a reference image. The image-based object recognition technique recognizes an object by comparing the user-captured image(s) (hereinafter referred to as the query\") to the stored reference image(s). Unfortunately, the appearance of 3D objects changes dynamically with the viewpoint. To cover the variation in appearance anticipated, we must be able to extract from the query and reference image(s) features sufficient to permit matching. We deem the traditional approach, many reference images for each object taken from different viewpoints, to be impractical. Our approach assumes that the reference image of an object is a single photo, while the query data is a video sequence from which features are extracted lor matching against the reference image. We proposed the above framework in a prior paper, and showed that it offered high accuracy when challenged with ideal data. To extend the framework such that it can handle real-world data, we propose an advanced technique that obtains the object's features from the captured video, and then matches the features to the reference image. An experiment verifies that the proposed technique can recognize real-world objects from captured videos. Its results show that the technique offers high accuracy.","PeriodicalId":294532,"journal":{"name":"2013 IEEE 2nd Global Conference on Consumer Electronics (GCCE)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132211162","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}
