The aim of this research was to determine the impact of voluntary information disclosure on informational content of share price. In this regard, future earnings response coefficient was used to determine the informational content of the share price about the future income information. Furthermore, share price synchronicity was used to evaluate the informational content of the share price about...

In studies of networked social privacy, disclosure is typically seen as either a separate behavior for each informational item, or measured by an aggregate disclosure tendency score. Our recent work shows that people’s disclosure behaviors are instead multidimensional: participants’ disclosure of personal information breaks down into a number of distinct factors. Moreover, people can be classif...

This paper provides a review of common statistical disclosure control (SDC) methods implemented at Statistical Agencies for standard tabular outputs containing whole population counts from a Census (either enumerated or based on a register). These methods include record swapping on the microdata prior to its tabulation and rounding of entries in the tables after they are produced. The approach ...

Masking methods protect data sets against disclosure by perturbing the original values before publication. Masking causes some information loss (masked data are not exactly the same as original data) and does not completely suppress the risk of disclosure for the individuals behind the data set. Information loss can be measured by observing the differences between original and masked data while...

Identity disclosure is one of the most serious privacy concerns in today’s information age. A wellknow method for protecting identity disclosure is k-anonymity. A dataset provides k-anonymity protection if the information for each individual in the dataset cannot be distinguished from at least k – 1 individuals whose information also appears in the dataset. There is a flaw in kanonymity that wo...

The effect of situational factors is largely ignored by current studies on information privacy. This paper theorized and empirically tested how an individual’s decision-making on information disclosure is driven by competing situational benefits and risk factors. The results of this study indicate that, in the context of an e-commerce transaction with an unfamiliar vendor, information disclosur...

The continuous growing amount of public sensible data has increased the risk of breaking the privacy of people or institutions in those datasets. Many protection methods have been developed to solve this problem by either distorting or generalizing data but taking into account the difficult trade-off between data utility (information loss) and protection against disclosure (disclosure risk). In...
