Privacy Enhancing Technologies (PET)

Differential Privacy

The safest technology for data sharing  

What is Differential Privacy Technology?

Differential Privacy is a technology that applies an irreversible blur effect to data analytics.  It is considered the reference standard for privacy due to its mathematical proven guarantees.

Why Differential Privacy ?

Differential Privacy is the technology that overcomes the limitations of traditional anonymization techniques by 
-    Providing quantification of  privacy protection level
-    Providing accuracy information and utility upfront 
-    Being resilient to re-construction attacks 
-    Enabling safe post-processing

​

Weakness of traditional anonymization tools
Traditional anonymization techniques are susceptible to re-identification attacks. Numerous instances demonstrate how anonymized datasets can be reconstructed by cross-referencing them with current or forthcoming public data (Examples). To address this, organizations often resort to generalizing data to the extent that it cannot be linked to individuals, but these generalizations are not accurate and have reduced utility.
