Smart home devices and data protection: How to protect your connected home
The growing popularity of smart home technologies raises new data protection issues
The intelligent networking of your own home is all the rage: voice assistants, smart thermostats, connected surveillance cameras and electronic door locks are no longer just gadgets for tech-savvy users, but are finding their way into more and more households. While everyday convenience is increasing, data protection issues and the security of personal data are also becoming increasingly important. What happens to the information collected? Who has access to it? How secure are the transmissions?
Users are faced with the challenge of making the right decisions to protect their privacy in their smart homes – because, as the past has shown, smart technologies have repeatedly been the target of hacker attacks and data leaks.
Past experience: security gaps and unauthorised access
In recent years, there have been repeated reports in the media of serious security problems with smart home products. Whether it's unauthorised access to cameras, spying on usage data or eavesdropping on sensitive conversations, such incidents highlight the enormous potential damage that unsecure devices can cause. It is particularly critical when passwords are transmitted in plain text or manufacturers provide inadequate privacy policies.
However, the issue of data protection and IT security has now received more attention in the industry, and consumers are also becoming increasingly aware of it. But has the level of security really increased as significantly as many manufacturers claim?
Data protection in the smart home: differences and stumbling blocks between providers
How were data protection and data security rated in practical tests?
A recent comparison of popular smart home systems showed that not all providers take data protection and transparency equally seriously. Aspects such as the data transfer behaviour of the apps, the protection of user accounts and the quality of the privacy policy were evaluated. Only a few systems achieved the top rating in terms of data protection.
Market leaders from Germany such as Bosch and AVM consistently refrained from linking usage data with personal data in the test – this means that user profiles are not created unless the user has expressly consented to this. In addition, data processing usually takes place in Germany or within the EU, which provides additional legal clarity in terms of the GDPR.
Characteristics of security-conscious providers – and where others fall short
Transparency and control are crucial: pioneering providers clearly inform users about data protection-related details, allow them to customise their data protection settings and keep their documentation up to date.
However, less privacy-friendly providers have outdated privacy policies, compulsory consent or excessive data collection.
Large international companies in particular rely on legal protection through international regulations such as the Data Privacy Framework – but also place high demands on users to take responsibility for themselves, as they often have to actively adjust settings. A high level of data protection does not therefore automatically result from market leadership, but requires critical examination of manufacturer information.
Tips for greater security in your own smart home
Technical precautions: Use passwords, updates and networks correctly
Many security risks can be minimised with simple measures: Never use default passwords, but choose strong, individual passwords for all devices. Make sure to install firmware and software updates promptly to close known security gaps. Consider connecting smart devices to a separate guest network to protect your main home network.
It is also worth taking a look at the data protection options offered in the app: many systems offer granularly adjustable data transfers and user rights. Check regularly which data actually needs to be transmitted.
Make informed decisions: compare, ask questions and check regularly
Before making a purchase, it is advisable to obtain detailed information about the data protection practices and security features of the selected system. The privacy policy should be up to date, understandable and comprehensive. Pay attention to transparent communication from the manufacturer and choose providers who take data protection seriously.
Regular checks of your devices, such as reviewing connected access points, testing rights assignments and, if necessary, resetting to factory settings, are recommended. Experience reports from independent consumer organisations or Stiftung Warentest can provide additional guidance.
Conclusion: Data protection in the smart home starts with conscious use
Those who stay in control protect their privacy
Developments in the smart home sector are advancing rapidly – and with them the challenges in terms of data protection. Users who inform themselves and proactively adjust settings can effectively minimise many risks. In addition to the technology itself, it is above all a sense of responsibility when handling personal data that ensures a secure and smart home.
Make good use of professional support during implementation
It is advisable to seek professional advice, especially for more complex installations or if you are unsure about certain aspects. Whether for private or commercial use, data protection experts and IT security specialists offer valuable support to ensure that your smart home is technically and legally secure.
