ANONOS

Anonymization techniques and pre-GDPR forms of tokenization (sometimes referred to as pseudonymization) are ineffective in today's data-driven world. These factors combine to enable unauthorized re-identification of individuals via the Mosaic Effect. The Mosaic Effect occurs when a person is indirectly identifiable via linkage attacks because some datasets can be combined with other datasets known to relate to the same individual, enabling the individual to be distinguished from others... In contrast, Statutory Pseudonymization - as now defined in GDPR Article 4(5) - enables Cryptographic Dynamism by requiring that you cannot re-identify individuals via linkage attacks, except with access to "additional information" that is stored separately under the control of the data controller. Traditional anonymization techniques using static (or persistent) tokens to replace repeated occurrences of identifiers within and across datasets remain vulnerable to reidentification via the Mosaic..
