As a result of their processing, the information redundancy is significantly reduced. This is of high importance for their efficient compression and for the reduction of the features space needed, when object recognition is performed. The basic obstacle for the wide application of PCA, is the high computational complexity. One of the approaches, used to overcome the problem, is to use algorithms, based on the recursive PCA. The well-known methods for recursive PCA are aimed at the processing of sequences of images, represented as non-overlapping groups of vectors. In the last several years, the interest towards the recursive PCA for 3D tensor images executed in sliding temporal window, was significantly increased. Such analysis is needed, for example for the convolution tensor decomposition in multi-layer neural networks, in the systems for 3D noise filtration, video compression, etc. In this work is proposed new method, called Sliding Recursive Hierarchical Adaptive PCA (SR-HAPCA), based on the HAPCA algorithm. The method SR-HAPCA retains all advantages of HAPCA towards the PCA: it decreases the number of calculations needed, and permits parallel implementation. Besides, the lower computational complexity of SR-HAPCA makes easier its application in real-time processing of 3D tensor images.","PeriodicalId":102480,"journal":{"name":"2017 8th International Conference on Information Technology (ICIT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130809953","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}

This paper therefore focuses on Small to Midsized Enterprises-SMEs in Jordan; hoping to have a better delivery of Big Data services with increased transparency and availability of technology, and the improved interaction with SMEs. This paper reviewed the relationships between Big Data and SMEs in general in Jordan. In addition, it examines the barriers for adopting Big Data among SMEs in Jordan. The paper mainly has used secondary research data and methods to provide a broad investigation of the issues relevant to Big Data, the reasons of those issues for SMEs in Jordan. The research is subject to academic journal articles, project reports, media articles, government and corporation based documents and other appropriate information. The study found that currently Jordan has been capitalizing comprehensively in developing its ICT sector, aiming at improving the performance of its public and private sector organizations, effectiveness, accurateness, time and fulfillment. However, Jordan needs to overcome barriers for adopting Big Data among SMEs which will improve efficiency and organizational effectiveness. By this way, SMEs in Jordan will be able to deliver information, high-quality customer centric and performance-driven services, and procedures, using information and communication technologies (ICT) to change the way they engage with customers and other businesses.","PeriodicalId":102480,"journal":{"name":"2017 8th International Conference on Information Technology (ICIT)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116706704","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, there are major concerns about security-related issues. A very critical security function is user authentication using passwords. Although many flaws have been discovered in password-based authentication, it remains the most convenient approach that people continue to utilize. Several schemes have been proposed to strengthen its effectiveness such as salted hashes, one-time password (OTP), single-sign-on (SSO) and multi-factor authentication (MFA). This study proposes a new authentication mechanism by combining user's password and modified characters of CAPTCHA to generate a passkey. The modification of the CAPTCHA depends on a secret agreed upon between the cloud provider and the user to employ different characters for some characters in the CAPTCHA. This scheme prevents various attacks including short-password attack, dictionary attack, keylogger, phishing, and social engineering. Moreover, it can resolve the issue of password guessing and the use of a single password for different cloud providers.","PeriodicalId":102480,"journal":{"name":"2017 8th International Conference on Information Technology (ICIT)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125007571","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}
