Why you hide what you know: Neuroscience behind knowledge hiding

Knowledge and Process Management, 2021
Knowledge hiding is the deliberate concealment of knowledge when requested. This study underscores three divergent elements of the knowledge hiding process. First, it underlines both the distinct internal and external factors that trigger the knowledge hiding process.

Parallel based Hiding of Sensitive Knowledge

2020 IEEE 32nd International Conference on Tools with Artificial Intelligence (ICTAI), 2020
Nowadays, privacy preserving data mining is an increasingly popular field of data mining research. frequent itemset-based approaches comprise a large category of techniques where the hiding is exemplified through the Apriori algorithm. This paper extends the work on a previously presented hiding scheme that sanitizes the input database by extending it ...

F̄-ladder knowledge and F̄-hiding knowledge discovery

2015 12th International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2015
By employing dual of one direction S-rough sets (dual of one direction singular rough sets) and its dynamic characteristic, this paper presents the concepts of F-ladder knowledge and F-ladder degree. Using these concepts, the discernibility theorem of F-ladder knowledge, the hiding-discovery theorem of maximum F-ladder knowledge, the hiding-discovery ...

Other Knowledge Hiding Methodologies

2010
Association rule hiding algorithms aim at protecting sensitive knowledge captured in the form of frequent itemsets or association rules. However, (sensitive) knowledge may appear in various forms directly related to the applied data mining algorithm that achieved to expose it.

EXACT KNOWLEDGE HIDING IN TRANSACTIONAL DATABASES

International Journal on Artificial Intelligence Tools, 2009
The hiding of sensitive knowledge in the form of frequent itemsets, has gained increasing attention over the past years. This paper highlights the process of border revision, which is essential for the identification of hiding solutions bearing no side-effects, and provides efficient algorithms for the computation of the revised positive and the ...

Sensitive Knowledge Hiding Application

2021
Diverse organizations store their business related data in their own databases. Some of them publish their data as is to third parties for research purposes. However, this way of data sharing has the risk of disclosing sensitive knowledge which the database may entail.

The dark triad and knowledge hiding

International Journal of Information Management, 2018
Abstract By drawing on psychological contract theory, this study examined the effects of the dark triad of personality traits (Machiavellianism, narcissism, and psychopathy) on knowledge hiding within organizations. We obtained 251 matched-pair data from respondents in a manufacturing company.

Exact Knowledge Hiding through Database Extension

IEEE Transactions on Knowledge and Data Engineering, 2009
In this paper, we propose a novel, exact border-based approach that provides an optimal solution for the hiding of sensitive frequent itemsets by (i) minimally extending the original database by a synthetically generated database part - the database extension, (ii) formulating the creation of the database extension as a constraint satisfaction problem,

A tree dries from the top: how manager’s knowledge hiding is morally disengaging employees to hide knowledge

Global Knowledge, Memory and Communication, 2023
Purpose The purpose of this study was to explicate how leaders’ knowledge hiding results in employees’ knowledge hiding. In addition, the study was intended to explore under what conditions leaders’ knowledge hiding affects employees’ moral disengagement more deleteriously.
