A New Approach For Copyright Authentication For Image Communication
No full textImage content authentication is to verify the integrity of the images, i.e. to check if the image has undergone any tampering since it was created. Digital watermarking has become a promising technique for image content authentication because of its outstanding performance and capability of tampering detection. However, many challenges for watermarking techniques for image authentication still remain unsolved or need to be improved, such as tamper localization accuracy, image quality, security, synthetic image protection, and so on. First, propose a watermarking technique for natural image authentication. By introducing the random permutation strategy in the wavelet domain, the proposed watermarking technique significantly improves the resolution of tampering detection with lower watermark payload. Second, study the unique characteristics of synthetic images and develop a novel watermarking scheme for synthetic image authentication. The proposed watermarking algorithm is fully compatible with the characteristics of synthetic images. With less pixels modified, the authentication system can still achieve pixel-wise tamper localization resolution. Compared with cryptography, it is much better suited for visual data protection. Digital watermarking could be completely compatible with multimedia systems because it is not only transparent to both the viewer and the system but also able to survive the common media processing as well. Image content authentication is one of the application fields of digital watermarking. For image content authentication, it has many advantages over digital signatures
Hybrid watermarking scheme with reduction of noises for color images
No full textWatermarking is the process of inserting predefined patterns into multimedia data in a way that the degradation of quality is minimized and remain at animperceptible level. Many digital water marking algorithms have been proposed in special and transformdomains. On the other hand, frequency domain -based techniques can embed more bits for watermark and are more robust to attack. Some transforms such as Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) are used for watermarking in the frequency domain. In this thesis, we compare the DCTwatermarking algorithms and especially the DWT watermarking algorithms based on robustness criteria

Secure Information Hiding Using Block Match Coding For VQ - Compress Images
No full textData is very essential in information system, so protecting the data from hackers is very important while transferring the data from one location to another. In this paper, an effective data hiding scheme is proposed which will help in achieving the aim of hiding data into compressed images. These compressed images can be reconstructed without any loss after the secret data is extracted at the decoder. For compressing the images Vector Quantization (VQ) technique is used. In VQ, index modifying and side match VQ (SMVQ) techniques can be used to hide data. Data hiding done by SMVQ technique can provide higher embedding capacity and lower bit rate but it is more time consuming. In contrast, data hiding done by index modifying technique can result into lower embedding capacity and a higher bit rate but it is less time consuming. The proposed scheme will try to merge the advantages of these two techniques while removing the disadvantages of others
Using Social Media To Gain Business Value
No full textAs the competition for Business is growing day by day the owners are concerned about the growth of their business.Social networking has become one of the most important parts of our daily life as it enables us to communicate with a lot of people. Social networking sites are created to assist in online networking.It is also is a platform where our creations and thoughts are presented to a huge lot of masses.Online social media represent a fundamental shift of how information is being produced, transferred and consumed. User generated content in the form of blog, posts, comments, and tweets establishes a connection between the producers and the consumers of information. Tracking the pulse of the social media outlets, enables companies to gain feedback and insight in how to improve and market products better. For consumers, the abundance of information and opinions from diverse sources helps them tap into the wisdom of crowds, to aid in making more informed decisions [1] Social media platform (SM) in particular comprises a flourishing new set of viral marketing mechanism that are growing exponentially. More and more companies are using SM because they know it works[1]. How much they spend and how long they continue to spend it will depend on how efficient SM proves to be in the long run. The measurement of social media effectiveness or ROI (Return on Investment) is the key factor in the long term success of SM marketing and management program.[1] The proposed system will calculate the gain of business by using social media as a platform.General Terms Business, Social Media, Information, ROI, Marketin
A STUDY TO ASSESS THE EFFECTIVENESS OF ACUPRESSURE IN REDUCING MENSTRUAL PAIN AMONG ADOLESCENT GIRLS WITH PRIMARY DYSMENORRHEA STUDYING IN SELECTED
No full textDysmenorrhea among adolescent girls may be managed using acupressure which is a non-invasive, cost-free, and timely way to manage their own discomfort. the aim of this study is to assess the effectiveness of acupressure in reducing menstrual pain among adolescent girls with primary dysmenorrhea studying in selected schools at bengaluru. a quasi experimental approach with pre and post- test control group time series was used in this study. sixty adolescent girls during menstruation were conveniently selected and 30 in experimental group and 30 in control group. the data was collected using visual analogue pain scale for pain perception, questionnaire and rating scale for menstrual discomforts. data was analysed using chi-square, and t-test. the adolescent girl’s mean age was 15yrs in control group and experimental group was 14yrs, both the groups 18(60.1%) had attained menarche at 13 years and above age, and majority of them were mildly malnourished. both the groups showed mild degree of menstrual discomfort and mild degree of pain in the pain scale 0-4. the mean pre-test pain score of experimental group was 5.23 and for control group 5.9. significant differences in control and experimental group observed before intervention showed t=2.339 (p<0.01) and after 2hrs of intervention t=13.695 (p<0.01). the study reveals that the acupressure on the sp6 meridian can be an effective non-invasive intervention for alleviating primary dysmenorrhea among adolescent girls for at least 2 hours. the result supported that acupressure application is a very suitable and practicable therapy of non-pharmacological measure of reduction in pain perception during menstruation for at least 2 hours. the findings suggested that acupressure at san yin jiao can be an effective, cost-free intervention for reducing pain and anxiety during dysmenorrhoea, and recommend its use for self-care of primary dysmenorrhoea

Self – Destruction Data System For Object Based Active Storage Framework
No full textWith the development of Cloud computing and popularization of mobile Internet, Cloud services are becoming more and more important for people’s life. People are more or less requested to submit or post some personal private information to the Cloud by the Internet. When people do this, they subjectively hope service providers will provide security policy to protect their data from leaking, so others people will not invade their privacy. As people rely more and more on the Internet and Cloud technology, security of their privacy takes more and more risks. On the one hand, when data is being processed, transformed and stored by the current computer system or network, systems or network must cache, copy or archive it. These copies are essential for systems and the network. However, people have no knowledge about these copies and cannot control them, so these copies may leak their privacy. On the other hand, their privacy also can be leaked via Cloud Service Providers (CSPs’) negligence, hackers’ intrusion or some legal actions. These problems present formidable challenges to protect people’s privacy. This paper presents a solution to implement a self-destructing data system, or SeDas, which is based on an active storage framework. The SeDas system defines two new modules, a self-destruct method object that is associated with each secret key part and survival time parameter for each secret key part. In this case, SeDas can meet the requirements of self-destructing data with controllable survival time while users can use this system as a general object storage system
A Graph-theory based approach for Water pipe-line system
No full textThe worldwide water supply represents a significant portion of the global energy consumption. This energy consumption, related to the collection, treatment and transportation of water, entails a large amount of costs. In this paper, an automatic, graph theory-based approach to route location and verification is presented. In this new approach, a component-based model is used to represent the topology of the pipes layout, and a modified matrix algorithm based on graph theory is used to locate all of the routes in a given pipes. This algorithm exhibits superior performance in the location and verification of routes and is universally applicable, irrespective of the pipe layout. When a pipe is modified, the designers can simply update the topological data for the pipe, and the new route information can be obtained automatically
Predictive Model for Box-office Success of Movies Using Social media
No full textSocial media comprises interactive applications and platforms for creating, sharing and exchange of user-generated contents. The past ten years have brought huge growth in social media, especially online social networking services, and it is changing our ways to organize and communicate. It aggregates opinions and feelings of diverse groups of people at low cost. Mining the attributes and contents of social media gives us an opportunity to discover social structure characteristics, analyze action patterns qualitatively and quantitatively, and sometimes the ability to predict future human related events.We have assessed how buzz and attention is created for different movies and how that changes over time. Movie producers spend a lot of effort and money in publicizing their movies, and have also embraced the Twitter medium for this purpose. Our hypothesis was the movies that are well talked about are well-watched.[2
