By applying Haar wavelet transform on the original image the four sub bands (Approximate band (LL), Horizontal band (LH), Vertical band (HL), Diagonal band (HH)) can be obtained. As detailed bands (LH, HL, HH) have lesser information of the original image the more number of LSBs of the detailed bands can be used to embed the secret information. After inserting the secret information in the sub bands inverse haar discrete wavelet transform is applied on the four sub bands. The values obtained after applying Haar IDWT(Inverse Discrete wavelet transform) may have fraction part or negative values. When the fraction part is truncated or negative values are made zero to obtain the pixel values in 0-255 range, the hidden secret information cannot be obtained completely after applying Haar DWT on the received image. In this paper a novel odd-even method is proposed to decrease the number of dissimilar coefficient values of the approximate band and thus to maximize the extraction of secret information hidden in approximate and detailed bands. Total numbers of coefficient values having different values at sender and receiver side are found. Larger the number of dissimilar coefficient values lesser is the secret information extracted. Peak Signal to Noise Ratio (PSNR) value is computed to analyse the quality of the stego image.","PeriodicalId":175757,"journal":{"name":"2018 Conference on Information and Communication Technology (CICT)","volume":"1218 19","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113994830","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}

CAPTCHAs were invented to ensure the security by confirming that the user using a machine is human or not. CAPTCHA is simply a test that tells human and the computer program apart. It is one of the important components that almost every commercial website include to determine whether the one using website is actually a human or not. Till date, most used CAPTCHAs are usually alphabets or numbers or combination of two. CAPTCHA can be solved by human beings only and not by bots and thus helps in stopping hackers and especially their crawlers also called spiders from acceding un-perplexed areas of the net. CAPTCHAs used till date have now become time-consuming and need more human efforts so that program could not crack it and this has become a major issue to consider as lead to time wastage. This paper has proposed a better model to generate CAPTCHA with the help of hand gesture recognition techniques which is more efficient than the traditional CAPTCHAs. In this method, a form has been displayed containing one CAPTCHA image showing some hand gesture from the database with a message displayed for ‘the user to copy the same gesture, the user then with his/her conscience has made some gesture in front of the camera of the system and then the model has verified the gesture made by the user is same as that shown or not. Following this method will surely ensure the identity of the user as it is not possible for the robot to understand by own how to copy the same gesture as shown in the image. These CAPTCHAs can be used in future by the websites to check whether the one using the website is a human being or a robot fulfilling the requirement of less human efforts and time. The experiments give satisfactory results of the proposed model.","PeriodicalId":175757,"journal":{"name":"2018 Conference on Information and Communication Technology (CICT)","volume":"585 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134219016","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}

Localization of sensor nodes play important role during data transmission from source to destination. Nodes which are connected with global positioning system(GPS) can be localized easily. But deployment cost is high in this case. On the other hand, if sensors are deployed in the physical environment such as dense forest area, localization of sensors is not always possible even with the help of GPS. Locating the sensor nodes which are not connected with GPS is the challenging task. Previously, various localization techniques have already been proposed. Some are range based localization and some are range free localization. However, there are some limitations of these approaches and localization error is high for most of the approaches. This paper proposed a novel localization technique in which nodes which are not connected with GPS can be able to detect its location with the help of Support Vector Machine (SVM). Proposed approach gives better result comparatively other existing approaches.","PeriodicalId":175757,"journal":{"name":"2018 Conference on Information and Communication Technology (CICT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125510888","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}

These physical objects after getting connected to the Internet can provide smart services and are therefore known as smart objects. For the realization of IoT, it is necessary for the smart objects to discover and interact each other without human intervention. The number of smart objects connected to IoT are increasing at a rapid rate, creating an overhead for the users of controlling these many smart objects. One smart solution to this problem is the use of Context-Aware Communication. This work aims to propose Enhanced Context-Aware CoAP Extension for smart objects discovery in Internet of Things (IoT), namely ECTX-CoAP, which is enhancement of CoAP-CTX [2]. CoAP-CTX is able to do Context-Aware discovery of smart objects but at the cost of discovery response time. The enhancement to CoAP-CTX is made by first, reducing discovery response time, comparable to CoAP and second, by adding the concept of Group Communication functionality to it other than multi-casting. The proposed ECTX-CoAP is implemented in Contiki using Cooja simulator. The experimental results show that the proposed enhancement has successfully reduced the discovery time and number of messages exchanged, also allowing users to access a group of smart objects efficiently.","PeriodicalId":175757,"journal":{"name":"2018 Conference on Information and Communication Technology (CICT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132007537","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}
