According to Article 16 GDPR - Right to rectification, “data subject shall have the right to obtain from the controller without undue delay the rectification of inaccurate personal data concerning him or her”. In the case of a call recording, the personal data categories provided by the data subject are the voice and the statements given during the call. As they were collected directly from the data subject, at the time of collection they should be considered as correct (if the data subject’s identity was validated, of course). The recording should be processed according to the scope of processing and archived according to the Data Retention Policy. If the data subject wants to correct certain information given during the call, he or she has this right by means of an additional statement – online, in writing, or recorded in a phone conversation. The initial recording shouldn’t be deleted after the new data has been collected, as this new information comes to complete or correct the initial information, which serves as proof that the data was collected correctly. The data subject must then be informed, according to Article 12 GDPR - Transparent information, communication, and modalities for the exercise of the rights of the data subject, regarding how his or her request was addressed, in a transparent manner. At Advisera, we have an EU GDPR Premium Documentation Toolkit which also contains templates for data controllers to collect data subject rectification requests and to provide answers to data subject rectification requests, please check the link below.
