De-anonymization: Difference between revisions

==How it works==

The core of de-anonymization involves making inferences to connect different types of obfuscated data, sometimes even across platforms.

== How data is anonymized ==

{{Notice|Note from Collaborator: While maybe irrelevant, it is important to understand how data is collected when it comes to it being anonymized.}}

Anonymization, in practice, also involves around collecting user data that is said to be "aggregated/de-identified basis" which involves the usage of [[wikipedia:K-anonymity|k-anonymity]]. There are also forms of data collection that also used in different methods such as [[wikipedia:T-closeness|''t''-closeness]], [[wikipedia:L-diversity|''l''-diversity]], and [[wikipedia:Differential_privacy|differential privacy]], however there are other forms of data collection that is also used, which have yet to be disclosed to the customers.

==Why it is a problem==

Many privacy policies describe the disclosure of anonymized data to third parties in an effort to limit unwarranted data collection. However, de-anonymization circumvents these privacy measures, allowing these third parties to engage in practices such as data sales or targeted advertising as normal.

However, de-anonymization circumvents these privacy measures, allowing these third parties to engage in practices such as data sales or targeted advertising as normal. This is however, an issue when it comes to privacy, as an adversary (e.g telemarketer) will be able to conduct an research on those records in order to attempt to reveal the data that is aggregated.[https://en.wikipedia.org/wiki/K-anonymity#Critiques_of_k-anonymity]
