Data Protection and Digital Signage: Challenges of Secure Information

Challenges and best practices regarding data protection and security in connection with digital signage systems
Published on February 8, 2024

Data protection has become a key concern in recent years. Due to the increasing digitalization of our society, companies and organizations are collecting and processing more personal data than ever before. Compliance with data protection regulations, in particular the revised Data Protection Act (revDSG) in Switzerland and the General Data Protection Regulation (GDPR) in the European Union, is essential for companies and organizations. This also applies to the area of digital signage, where the collection and processing of data from passers-by and customers can take place.

Data Protection Challenges in Digital Signage

1. Camera Surveillance and Data Protection

The use of cameras to capture images and videos can raise privacy concerns. It is important to ensure that no inappropriate collection or storage of personal information takes place. Anonymizing captured images can be a solution.

2. Collection of Analysis Data

Digital signage systems often collect analytics data to evaluate the effectiveness of ads and content. This data may include information about the behavior of people near the screens. It is important to be transparent about data collection and only use the data for legitimate purposes.

3. Security of Content Management Systems (CMS)

The security of the platforms and systems used to manage digital signage content is critical. Vulnerabilities in these systems could enable hacker attacks and put sensitive information at risk.

4. Remote Access and Control

The ability to update and control digital signage content remotely is a great advantage. At the same time, however, this poses a security risk if appropriate security precautions are not taken.

Preserve Data Privacy: Best Practices in Digital Signage

To ensure data protection in digital signage systems, companies and organizations should follow best practices:

1. Transparency and Consent

Inform the public about the data that is being collected and, if necessary, obtain consent. This is particularly important if cameras or other data collection technologies are used.

2. Data Minimization

Only collect the data that is required for the intended purpose. Avoid excessive data collection.

3. Security of CMS and Networks

Ensure that content management systems and networks used for digital signage are adequately secured. This includes regular security updates and the implementation of firewalls.

4. Protection of the Collected Data

The collected data should be stored securely and protected against unauthorized access. Encryption and secure access control are crucial.

5. Regular Data Protection Checks

Conduct regular data protection audits to ensure compliance with data protection regulations. This may include training staff on data protection compliance.


Privacy and security are fundamental concerns in the digital era, and they apply equally to the digital signage sector. While digital signage offers many benefits, especially in terms of communication and marketing, it is crucial to respect people's privacy and data protection rights. Companies and organizations that follow privacy and security best practices in digital signage systems can maximize the benefits of this technology without compromising privacy.
