üks privaatsuspõhimõtteid biomeetriasüsteemides:
eelistada protseduure, millega andmesubjekt nõustub

ISO/IEC TR 24714-1: 2008, 4.2.3:
where feasible and practical, opt-out or opt-in procedures
should be made available to the subject;
in general, opt-in is the preferred option.

ISO/IEC 29100:
opt-in
process or type of policy whereby the personally identifiable information (PII) principal is required to take an action to express explicit, prior consent for their PII to be processed for a particular purpose
Note. A different term that is often used with the privacy principle ‘consent and choice’ is “opt-out”. It describes a process or type of policy whereby the PII principal is required to take a separate action in order to withhold or withdraw consent, or oppose a specific type of processing. The use of an opt-out policy presumes that the PII controller has the right to process the PII in the intended way. This right can be implied by some action of the PII principal different from consent (e.g., placing an order in an online shop).
