Further study proves lie of “anonymous” data
Anonymous data is often not really anonymous at all, in many data records individuals can be uniquely identified even without a name. A new study illustrates the amazing precision with which this can be done. Many companies and databases undermine the basic data protection regulation.
Not everywhere where it says anonymous is also anonymous in it. This is made clear by a study in the scientific journal “Nature”. The researchers can identify 99.98 percent of Americans in each data set, with only 15 characteristics such as age, place of residence or nationality.
The scientists’ example: a cheap health insurance company sells customer data, but only “anonymously” and only from a fraction of the database. The study makes it clear: this is not true anonymity, the data is not secure. People are simply too unique to hide in databases. Removing names only makes records pseudonymous, not anonymous. With an online tool, anyone can trace the de-anonymization themselves.
The authors write that “even highly fragmented anonymized data records do not meet the modern anonymization standards of the Basic Data Protection Ordinance”. Their results question “the technical and legal adequacy” of simply deleting directly identifying data types and not worrying about identifiability using other data types.
Data is never completely anonymous
“The study once again shows very beautifully what we have known for a long time,” says data protection researcher Wolfie Christl to netzpolitik.org. “As long as data records relating to individuals are being processed, no form of anonymization can prevent individuals from being reidentified with complete certainty.
