the controller shall communicate the personal data breach to the data subject without undue delay.

2. The communication to the data subject without undue delay. 2. The communication to the

data subject referred to in paragraph 1 of this article 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 points B, C, and, D, of Article 33.3.

3. The communication to the data subject referred to in paragraph 1 shall not be required if any of the following conditions are met. A, the controller has implemented appropriate technical and

organizational protection measures, and those measures were applied to the personal data

affected by the personal data breach, in particular those that 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 it, such as encryption. B, the controller has taken subsequent measures

which ensure that the high risk to the rights and freedoms of data subjects referred to in paragraph

one is no

there shall instead be a public communication or similar measure whereby the data subjects are

informed in an equally effective manner. Four, if the controller has not already communicated the personal data breach to the data

subject, the supervisory authority, having considered the likelihood of the personal data breach

resulting in a high risk, may require it to do so or may decide that any of the conditions

referred to in paragraph 3 are met.
