Disclosure Control is the discipline concerned with the modification of data containing confidential information about individual entities, such as persons, households, businesses, etc. in order to prevent third parties working with these data from recognizing entities in the data and thereby disclosing information about these entities. In very broad terms, disclosure risk is the risk that a gi...

In this paper, we define several disclosure risk measures for microdata. We will analyze disclosure risk based on the disclosure control techniques applied to initial microdata. Disclosure Control is the discipline concerned with the modification of data containing confidential information about individual entities, such as persons, households, businesses, etc. in order to prevent third parties...

It is well understood that when corporate insiders trade shares in their firms stock for the sole purpose of maximizing trading profits, they benefit from asymmetric information, and consequently, favor minimal corporate financial disclosure requirements. We demonstrate that when insiders are risk-averse and have other motives for trade, such as liquidity needs, they can actually be harmed by a...

Traditionally, statistical agencies generally release outputs in the form of microdata and tabular data. Microdata contain data from social surveys and tabular data contain either frequency counts, such as for census dissemination, or magnitude data typically arising from business surveys, eg. total revenue. For each of these traditional outputs, there has been much research on how to quantify ...

Statistical database protection is a part of information security which tries to prevent published statistical information (tables, individual records) from disclosing the contribution of specific respondents. This paper shows how to use information-theoretic concepts to measure disclosure risk for tabular data. The proposed disclosure risk measure is compatible with a broad class of disclosure...

The disclosure problem relates to the possibility of identifying individuals in the released statistical information . The paper evaluates the disclosure risk on a 3% sample of individual data from the Slovene 1991 Population Census . The concept of uniqueness is used for this purpose . The level of regional aggregation, the number of identifying variables and the grouping of the categories are...

The performance of Statistical Disclosure Control (SDC) methods for microdata (also called masking methods) is measured in terms of the utility and the disclosure risk associated to the protected microdata set. Empirical disclosure risk assessment based on record linkage stands out as a realistic and practical disclosure risk assessment methodology which is applicable to every conceivable maski...
