In this paper, a low complexity joint fingerprint and decryption (JFD) scheme based on exclusive-or operations has been proposed, which can be effectively used for traitor tracing. The scheme encrypts only sub-pixels of the entire image using a tiny lookup table generated by a stream cipher. In the decryption process, some pixels can be completely recovered and the fingerprinting process depends on four different directions of sub-image blocks. The method successfully leaves the user's fingerprint during decryption and produces slightly different media copies. The experimental results show that the proposed scheme is highly effective in terms of perceptual security and fingerprinted visual quality.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124729093","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 challenging because the aging variation is specific to a given individual and is determined by not only the person's gene, but also by many external factors, such as exposure, weather conditions (e.g. ambient humidity), health, gender, living style and living location. Age categorization is a multiclass problem. Lack of a good public aging dataset makes it difficult to estimate age from face image. Due to large multiclass nature of human ages, it is difficult to collect large aging database. In this paper, we proposed a novel approach to collect high quality aging face images. Application Programming Interface (API) services provided by Microsoft Search Engine Bing are adopted for this purpose. Automatic collection of age-specified query images was implemented in C# programming interface with Microsoft BING API services. The experimental results of age estimation has verified that our approach is a good way to collect aging images in huge volume since internet hosts a large number of images with age labeling. It serves as an alternative cheap platform to gather face images for age classification.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128575360","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 rapidly increasing traffic demand is also driven by the growing popularity of mobile data services, which is placing high-capacity requirement on the backhaul. Due to advances in wavelength division multiplexing (WDM) technology, WDM based architectures have been considered as promising candidates for next generation optical access, such as WDM passive optical network (PON), and hybrid WDM/time division multiplexing (TDM) PON. Meanwhile, resilience technique will play a more prominent role in emerging access networks due to their significantly increased capacity and coverage compared to the current deployments. Therefore, efficient resiliency mechanisms are highly required to enable uninterrupted network operation where a certain level of reliability performance can be guaranteed. In this work, we first evaluate reliability performance of each segment of next generation optical access networks and then identify the most important part for protection. A particular attention is paid to the reduction of failure impact.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128769363","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}

Existing MANET routing protocols set up an end-to-end path between source and destination prior to data forwarding. Maintaining a connected path before data delivery may not work well when the network is partially disconnected or disrupted. This paper discusses Opportunistic Multi-link Delay Tolerant Routing (OMDTR) which is designed to provide data delivery in the network where fully connected network topology is not guaranteed. OMDTR learns the local network connectivity and deliver the data if there is connectivity within two-hop. OMDTR exploits the robustness of flooding-based routing when there is no local network connectivity. Performance measurements of OMDTR protocol show that OMDTR increases the data delivery compared to pure flooding-based routing and pure end-to-end routing in mobile multi-hop wireless network with relatively high and low network density.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125730032","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 this paper, a new and robust watermarking method is proposed to address this security issue. Specifically, signature information and textual data are inserted into the original medical images. The integer wavelet transform (IWT) are combined with singular value decomposition (SVD) to provide robustness in the proposed method. Meanwhile, differential evolution (DE) is used to optimally design the quantization steps (QSs) for controlling the watermarking strength. With hybrid techniques such as IWT, SVD, and DE, the proposed watermarking algorithm not only achieves good imperceptibility, but also high robustness. Experimental results demonstrate that the proposed method outperforms existing methods.","PeriodicalId":184544,"journal":{"name":"2013 9th International Conference on Information, Communications & Signal Processing","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114576074","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}

Some mathematical skills on how to transform the beamformer with CMRs into convex programming problems are introduced.
