Section 66

Notifying data subjects affected by a personal data breach

(1) If a personal data breach is likely to result in a substantial risk to the legally protected interests of natural persons, the controller shall notify the data subject of the personal data breach without delay.
(2) The notification of the data subject pursuant to subsection 1 shall describe in clear and plain language the nature of the personal data breach and contain at least the information and measures referred to in Section 65 (3) nos. 2 to 4.
(3) Notification shall not be required if any of the following conditions are met:
1. the controller has implemented appropriate technical and organisational protection measures, and those measures were applied to the personal data affected by the personal data breach, in particular those that render the personal data unintelligible to any person who is not authorized to access them, such as encryption;
2. the controller has taken subsequent measures which ensure that the substantial risk referred to in subsection 1 is no longer likely to exist;
3. it would involve a disproportionate effort; in this case, a public communication shall be made or a similar measure taken to inform the data subjects in an equally effective manner.
(4) If the controller has not informed the data subjects of a personal data breach, the Federal Commissioner may formally determine that, in his or her opinion, the conditions referred to in subsection 3 have not been met. In doing so, the Federal Commissioner shall consider the likelihood of the personal data breach resulting in a high risk as referred to in subsection 1.
(5) The notification of data subjects pursuant to subsection 1 may be delayed, restricted or omitted under the conditions referred to in Section 56 (2) unless the interests of the data subjects outweigh those of the controller owing to the high risk resulting from the personal data breach as referred to in subsection 1.
(6) Section 42 (4) shall apply accordingly.
