The capabilities described, such as allowing for selective disclosure of attributes, permitting the sharing of attribute references instead of actual values, and enabling alteration or deletion of information, align with the privacy engineering objective of disassociability. Disassociability refers to the ability to separate data from the individual to whom it pertains, thereby minimizing the linkage between personal data and the data subject.
This concept is crucial for reducing privacy risks and ensuring that personal information is only shared on a need-to-know basis. The IAPP emphasizes disassociability as a fundamental principle in privacy engineering, helping to protect individuals' privacy by limiting the exposure of their personal information.
