A Novel Sanitization Approach for Privacy Preserving Utility Itemset Mining
Data mining plays a vital role in today’s information world wherein it has been widely applied in various business organizations. The current trend in business collaboration demands the need to share data or mined results to gain mutual benefit. However it has also raised a potential threat of revealing sensitive information when releasing data. Data sanitization is the process to conceal the s...
متن کاملPrivacy Preserving Utility Mining Using Sanitization Approach
This thesis is basically designed for privacy preserving utility mining using sanitization approach. In this work itemsets are provided safety using an approach , firstly we will calculate the utility of all itemsets as the product of item cost and its number of transactions, then we will set a threshold utility which will be the average of max and min utility. Now, we will try to reduce the di...
متن کاملA Partial Optimization Approach for Privacy Preserving Frequent Itemset Mining
While data mining has been widely acclaimed as a technology that can bring potential benefits to organizations, such efforts may be negatively impacted by the possibility of discovering sensitive patterns, particularly in patient data. In this article the authors present an approach to identify the optimal set of transactions that, if sanitized, would result in hiding sensitive patterns while r...
متن کاملPrivacy Preserving Outsourcing for Frequent Itemset Mining
Cloud computing uses the paradigm of data mining-as-a-service. A company/store lacking in mining expertise can outsource its mining needs to a service provider (server). The item-set of the outsourced database are the private property of the data owner. To protect this corporate privacy, the data owner encrypts the data and sends to the server. Based on the mining queries sent from client side,...
متن کاملA New Algorithm for High Average-utility Itemset Mining
High utility itemset mining (HUIM) is a new emerging field in data mining which has gained growing interest due to its various applications. The goal of this problem is to discover all itemsets whose utility exceeds minimum threshold. The basic HUIM problem does not consider length of itemsets in its utility measurement and utility values tend to become higher for itemsets containing more items...
