Phishing came into focus in 1996, and from then it is emerging out as one of the biggest cybercrime attacks on internet. The solutions for handling phishing attacks include: detecting the activity and filtering it from normal activity (Phished Email and Website detection), preventing it by the use of excellent user interfaces and login authentication schemes and user training so that users can prevent themselves from being falling into it. Researchers have focused on all the three techniques for solving phishing attacks. However the previous techniques handle the problem of phishing to an extent but are incomplete, and complex to implement or use in actuality. The research work in this paper will be focused on the critical review of previous schemes proposed, with a novel scheme for preventing phishing attacks with the use of four characters secret information display during login authentication. The novelty of the scheme lies in its low complexity, better user understandability and real time implementation ability. This paper also describes the analyzed results of a real time experiment done to evaluate the scheme. Our results show great improvement with a total of only 13.5%, 1% and 3% user's phished in rigorous phishing attempts, of various kinds for a period of one month.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133735549","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 performance, features and aesthetics of the applications play an important role in its increasing importance. Also, upcoming device models are looking for more energy-efficient performance as a step towards green computing. This is realized by ARM cores. But the performance and energy efficiency depend not only on the core, but the application also. Such efficiency can only be managed by efficient code from the compiler. This is primarily managed in its back-end, which comprises of the latter half of the compiler's control flow (intermediate code generator to code generator). If the code is optimized by the compiler, it will perform with lesser CPU cycle requirements, and save more energy. So, optimizing the code saves both time and power. In order to do so, compilers like GCC already provide a lot of options. But due to the generic structure of GCC, it performs very little ARM-specific optimizations. Here, we aim to improve the performance of the GCC optimizers for the ARM cores by better instruction selection (machine idioms and instruction combining), and choosing the order of optimizations appropriately, since in some cases, a set of optimizations may pave the way for improving some others. The end result is targeted to give about 30% increase in efficiency in most cases.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"68 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126972122","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}

Securing inter-sensor communications within BANs is essential for preserving not only the privacy of health data but also for ensuring safety of healthcare-delivery. The proposed technique presents a scheme for enabling secure inter sensor communication within BAN. The proposed method allows neighbouring nodes in a BAN to agree to a symmetric (shared) cryptographic key, in an authenticated manner, using physiological signals obtained from the subject. The proposed method generates the key from the physiological signals sensed by the sensors and converts it into frequency domain and generates features. The generated features are transformed into a cubic spline curve and the coefficients are concatenated to form the key. The key is then transmitted to the receiver by a new fuzzy vault cryptographic method, where the receiver decrypts (using cubic spline interpolation) and finds the key. This key agreement can provide security for the e-health applications.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121826047","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}

Text extraction in video documents, as a momentous research division of content-based information retrieval and indexing, continues to be a topic of much interest to researchers. Text extracting is demanding owing to a range of setbacks like complex background, varying font size, different style, lower resolution and blurring, position, viewing angle and so on. In this paper we propose a hybrid method where the two most well-liked text extraction methods explicitly region based method and connected component (CC) based method comes together. The former method is used to obtain the text prevailing confidence where as the latter is used for text extraction and grouping. The video splitting and key frame detection is followed by the preprocessing to designate the text region indicator. The extracted features are scrutinized using artificial neural network as the classifier and lastly grouped into words/lines based on the bounding box distance. We evaluated the performance of the proposed approach on various videos and obtained considerable results when weighed against the existing methods.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125875047","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}

However, the strict constraints in terms of processing power, storage, bandwidth etc. pose a great challenge to data processing in WMSN. Transmitting raw data is very costly while limited processing power prevents sophisticated multimedia processing. Exploring low-overhead data compression technique is a solution towards this problem. In this paper we propose an energy-saving audio data compression technique for WMSN combining wavelet lifting with a newly proposed difference detection technique. We consider the application domain where data are co-related. To exploit this co-relation we propose to run one wavelet round followed by a dynamic number of difference round and thereby, local communication overhead is saved compared to pure wavelet based scheme without sacrificing the target of sending data with less number of bits to the sink. Moreover, in addition to capturing spatial correlation by wavelet, this scheme captures temporal correlation by introducing the difference detection round.\u0000 Performance of the proposed scheme is evaluated through simulation where efficacy of the scheme is not only evaluated in terms of energy consumption but also by computing SNR. The scheme is compared with one of the existing schemes. The results confirm our scheme's supremacy over the competing scheme both in terms of energy saving and signal reconstruction quality (SNR).","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125083213","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}

Noise can be a big offence in affecting encoding efficiency because it can be present throughout an entire application. Noise has the technical definition for various anomalies and unnecessary variations that get built-in into a video signal. Noise reduction enables better video quality at lower bit rates by making the source look better and decrease the video complication prior to the any process. In this proposed method we adapted the spatial video denoising methods, where image noise are reduced and are is applied to each frame individually. Since there is a great deal of removing noise from video content, this paper has been devoted to noise detection and filtering methods that aims the removing unwanted noise without affecting the clarity of scenes which contains necessary information and rapid movement. The aim of this work is to produce precise segmentation of images using intensity information along with neighborhood relationships. Most of the results of color image segmentation are based on gray level image segmentation methods with different color representations were published. Image segmentation techniques such as histogram threshold, clustering in segmentation, region growing, edge detection, fuzzy methods, and neural networks can be extended to color images.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130418387","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}
