Be careful when scanning: How to protect yourself from dangerous QR codes!
Erlangen, Deutschland - QR codes are hardly an integral part of modern everyday life. They enable lightning -fast access to information and additional content via smartphones. The term QR code stands for "Quick Response Code" and denotes square codes with graphic patterns that are slightly scanbar. As fau , QR-codes can code up to 4206 characters and are used in various areas, from online banking to the automotive industry.
The popularity of QR codes, especially for smartphone owners, is shown in their extensive use on posters, flyers or tickets. They often lead to websites that provide further information. While the codes fulfill useful functions, their use also carries risks. According to the test , fraudsters can use QR-CODES to refer to damaged websites that can contain the Trojaner.
security risks in dealing with QR codes
A central problem is that users cannot see where it leads before scanning a QR code. This harbors considerable security risks because the codes can theoretically contain links to dangerous websites. The Federal Office of Information Technology (BSI) has already warned of fraudulent QR codes. VR codes in public locations, such as in the subway or on trade fairs, can be manipulated.
It is important to know that QR codes do not damage smartphones themselves. The risk only arises when the user clicks on a harmful link. Android users in particular whose devices can install software from any sources are susceptible to them. For this reason, it is advisable to use a safe barcode scanner that shows the Internet address before calling. Good scanners can also decipher short links and display the original address.
data protection and QR codes
In terms of data protection, QR codes are less questionable as long as you do not store any personal data. As dpc data protection , QR-codes do not fall under the General Data Protection Regulation (GDPR), provided they do not contain any personal information. However, users should be informed if QR codes are used to process personal data. The responsibility lies with the providers who have to clarify the users about data processing.
Another aspect is that QR codes encrypt data, but everyone can decipher it with a suitable device. The use of QR codes in so-called cloud applications is also relevant, since the cloud operator processes the information here, not the provider of the QR code itself. The safety and protection of the data therefore depend heavily from the respective applications and their operators In summary, it can be said that QR-Codes are practical tools in the digital age, but a certain level of caution is required to minimize the risks. Users should always be vigilant and become aware of the potential dangers in order to be able to deal with QR codes safely.
