Title

Collection and Data Minimization

Control

Section 4.2 requirement 2 permits the collection of only the PII necessary to validate the existence of the claimed identity and associate the claimed identity to the applicant, based on best available practices for appropriate identity resolution, validation, and verification. Collecting unnecessary PII can create confusion regarding why information not being used for the identity proofing service is being collected. This leads to invasiveness or overreach concerns, which can lead to loss of applicant trust. Furthermore, PII retention can become vulnerable to unauthorized access or use. Data minimization reduces the amount of PII vulnerable to unauthorized access or use, and encourages trust in the identity proofing process.
