A study published in the International Journal of Electronic Governance finds out if any of the five "anonymous" applications for social networks are safe, because they do not allow a third party to view personal data or track users.
Scientists at the Open University of Cyprus explain how anonymity of personal data should protect user privacy from data mining and data publishing systems. However, this is not always the case. Indeed, the removal of personal identifiers does not ensure confidentiality, since there are methods that can be easily used to create a unique fingerprint based on the characteristics of the data itself, which can then be used to identify the user's identity with or without additional information. ,
It has long been known that three pieces of information — date of birth, gender, and zip code — can be used to identify 87 percent of the US population. In addition, if such information is not available to another party who wants to deanonymize activity on this device or application, then data points such as mobile subscriber identity (IMSI), medium access control address (MAC), international mobile equipment Identification data ( IMEI), Android identifier, Google Advertising Identifier (GAID), etc. Can be used to focus on what is essentially a unique fingerprint for this device, and from there, possibly on the caller. Anonymity cannot be guaranteed, it seems, in any system or application, regardless of promises and regardless of regulations, such as the General Data Protection Regulation (GDPR) for citizens of the European Union (EU).
In fact, “our analysis shows that the processing of personal data is even carried out in so-called anonymous applications, which, in turn, implies that the anonymity of the user cannot be ensured, while the corresponding privacy policies can leave room for further improvement” - the team writes.
