An efficient aggregation scheme resisting on malicious

Jul 01, 2020 To address this problem, a number of privacy-preserving data aggregation schemes have been proposed in the literature. In this paper, we present a new type of attack, called malicious data mining attack, by which the adversary can infer a target user’s electricity usage data. When considering this attack, the majority of existing data

Data Generalization in Data Mining: 5 essential principles

Sep 12, 2020 Data Generalization is the process of summarizing general features of objects in a certain class and producing characteristic rules. In this process, users use concept hierarchies in order to convert low-level attributes of data into high-level attributes of data. For instance, age data can be in the form of (20, 40) in the dataset; therefore

So, the first strategy - and this one is first because we see it a lot - is aggregation. We’ll combine two or more attributes or objects into a single attribute or object. This can be where we are trying to reduce the scale of our data, reduce the number of attributes or objects. So, we could, for instance, combine two attributes - to combine a high-temperature attribute and a low-temperature attribute in order to get a
