The introduction of a KI phonebot promises enormous efficiency gains for customer communication. However, with all technical enthusiasm, a decisive aspect must not be neglected: Data protection.

Once an AI system processes personal data such as names, telephone numbers or order details, it is subject to the strict regulations of the General Data Protection Regulation (GDPR).

This article explains the most important data protection needs for the use of AI telephone bots and shows how to ensure a legally compliant operation.

An AItelephone bot necessarily processes personal data to perform its tasks.

The voice of a caller alone can already be considered as a biometric and so especially protective date.

In addition, further information such as names, addresses or customer numbers is often exchanged in the course of the conversation. According to Art. 4 No.

1 GDPR, this is personal data whose processing is subject to strict rules.

Violations of the GDPR may have drastic effects ranging from high fines to reputational damage. A data protection-compliant use is so not an option, but a compelling need.

The 5 main principles for GDPR-compliant use

In order to operate an AI telephone bot in accordance with the law, you must observe the principles of the GDPR.

  This can be done by a clear statement and the subsequent continuation of the conversation by the caller.

• Contract fulfillment (Art.

  6 para.

  1 lit. b GDPR): If the call serves to initiate or fulfill a contract (e.g. an order or booking), this can serve as a legal basis.

2. Transparency and information obligations (Art. 13 & 14 GDPR)

You must inform the caller clearly and understandably that he speaks with an AI and not with a human being.

You also need to clarify the purpose and scope of data processing.

This information should be provided on the website at the beginning of the conversation and in addition in your privacy statement.

3. Data economy (Art. 5 para. 1 lit. c GDPR)

Short: Only process the data absolutely needed for the respective purpose.

Only process the data absolutely needed for the respective purpose. The bot should not request more information than is needed for processing the request.

Talk recordings should only be stored, who
