This data could be passed on to third parties or, in the event of a Data protection breach fall into the wrong hands, which could lead to identity theft or other forms of abuse.
Smart Home Data Protection
In particular, the increased circulation of personal data due to the networking of devices via WLAN, Bluetooth or mobile phone networks must be viewed critically. This is because these networks are not always adequately secured. And even if one does not become the victim of a hacking attack, there are numerous possibilities for third parties, such as manufacturers or even craftsmen, to gain more and more insight into sensitive data areas. User profiles can be created from the data of the networked devices and behaviour or habits can be estimated. A sensitive intrusion into privacy and the loss of control over one's own data.
In Europe, the General Data Protection Regulation, how manufacturers and providers may handle personal data. Among other things, providers must observe the following:
- Data may only be collected with the consent of the data subject.
- The processing of the data must be for a specific purpose. For example, an e-mail address provided to receive product updates may not be used for advertising.
- The collection of data must also be earmarked for a specific purpose, e.g. registration for software does not require information on religious affiliation.
Even though the GDPR regulates many issues in this regard, there are still no specific guidelines or technical standards for smart home applications. Smart homes offer a convenient and innovative way to automate and connect our homes. However, with these technological advances come privacy concerns. As smart home devices are often connected to the internet and can collect and process personal data, it is important to keep privacy issues in mind.
