Machine learning concepts for correlated Big Data privacy

With data becoming a salient asset worldwide, dependence amongst data kept on growing. Hence the real-world datasets that one works upon in today’s time are highly correlated. Since the past few years, researchers have given attention to this aspect of data privacy and found a correlation among data. The existing data privacy guarantees cannot assure the expected data privacy algorithms. The privacy guarantees provided by existing algorithms were enough when there existed no relation between data in the datasets. Hence, by keeping the existence of data correlation into account, there is a dire need to reconsider the privacy algorithms. Some of the research has considered utilizing a well-known machine learning concept, i.e., Data Correlation Analysis, to understand the relationship between data in a better way. This concept has given some promising results as well. Though it is still concise, the researchers did a considerable amount of research on correlated data privacy. Researchers have provided solutions using probabilistic models, behavioral analysis, sensitivity analysis, information theory models, statistical correlation analysis, exhaustive combination analysis, temporal privacy leakages, and weighted hierarchical graphs. Nevertheless, researchers are doing work upon the real-world datasets that are often large (technologically termed big data) and house a high amount of data correlation. Firstly, the data correlation in big data must be studied. Researchers are exploring different analysis techniques to find the best suitable. Then, they might suggest a measure to guarantee privacy for correlated big data. This survey paper presents a detailed survey of the methods proposed by different researchers to deal with the problem of correlated data privacy and correlated big data privacy and highlights the future scope in this area. The quantitative analysis of the reviewed articles suggests that data correlation is a significant threat to data privacy. This threat further gets magnified with big data. While considering and analyzing data correlation, then parameters such as Maximum queries executed, Mean average error values show better results when compared with other methods. Hence, there is a grave need to understand and propose solutions for correlated big data privacy.

ASSESSMENT OF CONFLICTS AT WORK PLACE AND SOCIAL SUPPORT AMONG MARKETING PROFESSIONALS

Now a day's most of the private company employees especially marketing related professionals are facing both mental and physical stress in their work place. The present study was conducted to know about the conflicts at workplace that lead to stress and social support at work to reduce the stress among marketing professionals. An exploratory research design was followed. Sample size of 30 respondents from marketing background was selected by using purposive sampling technique. For both the conflicts at workplace and social support, standard scales were adopted to collect the data. Correlation was used to compare the data. Results exposed that most of the respondents have very much social support from their spouse, friends and relatives. Respondents have moderately agreed for having conflicts at work place which led to stress. Significant positive relationships were found between income and social support; while significant negative relationships were observed between income and conflicts at workplace.
