What is de-anonymization attack?
In this work, we focus on a specific inference attack called the de-anonymization attack, by which an adversary tries to infer the identity of a particular individual behind a set of mobility traces.
What is anonymization service?
Anonymization is a data processing technique that removes or modifies personally identifiable information; it results in anonymized data that cannot be associated with any one individual. It’s also a critical component of Google’s commitment to privacy.
What is de-anonymization by network operators?
De-anonymization is a data mining strategy in which anonymous data is cross-referenced with other data sources to re-identify the anonymous data source. Any information that distinguishes one data source from another can be used for de-anonymization.
How do you implement Anonymization?
Data masking Data masking refers to the disclosure of data with modified values. Data anonymization is done by creating a mirror image of a database and implementing alteration strategies, such as character shuffling, encryption, term, or character substitution.
Can anonymized data be de anonymized?
De-anonymization is a technique used in data mining that attempts to re-identify encrypted or obscured information. De-anonymization, also referred to as data re-identification, cross-references anonymized information with other available data in order to identify a person, group, or transaction.
Which is the best definition of de-anonymization?
De-anonymization, also referred to as data re-identification, cross-references anonymized information with other available data in order to identify a person, group, or transaction. De-anonymization is the practice of re-constituting the private information stored in encrypted or otherwise obscured data.
Can a person retrace a data anonymization process?
However, even when you clear data of identifiers, attackers can use de-anonymization methods to retrace the data anonymization process. Since data usually passes through multiple sources—some available to the public—de-anonymization techniques can cross-reference the sources and reveal personal information.
What causes anonymization of a computer data set?
Information that enables an individual to be distinguished as a particular computer user is dependent on the context and the availability of other data sets that, when compared to the de-identified data set, could cause identification to occur regardless of whether the data is “personally identifiable” in the traditional sense.
What’s the difference between de-identified and anonymized data?
In such cases, anonymized data is a particularized subset of de-identified data. In this document, “de-identified” and “anonymized” will be considered synonymous terms. This term is also understood as a health information concept as it relates to the Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule.
