The QR code, which we also call Bidi (although they are not the same) is a two-dimensional code created in 1994 by a subsidiary company of Toyota. Its acronym “QR” derives from English “Quick Response” and it differs from the Bidi code by the three squares in the corners that allow the position of the code to be detected when scanning it.
We are experiencing a digital transformation, where cybersecurity is born with the need to safeguard this transformation process. With the Master in Cybersecurity Management, Ethical Hacking and Offensive Security You will be trained in this area.
Initial function of QR code
Although they were initially created to register vehicle spare parts, today it has many more uses, especially consumer-oriented, thanks to the readers built into Smartphones.
And it would not be until 2002 when they really became important. They would be the mobile phone companies those that are beginning to give it a more consumer-focused use, especially to advertise their products.
For example, the QR letters, especially thanks to the pandemic since in this way, we avoid contact with paper letters and the risk that could entail.
What happens is that every time we consult the QR letters, or any content or link from a bidi code, we provide important data such as the location and our interest in the product or service consulted, information that would interest many marketing companies.
Data collection
As we have been able to read in The New York Times, there are systems that collect data from QR letter queries that can even be used to track customers. Consulting the menu in QR plus the data that can be obtained from the connection, browser, etc., provides much more information than we think.
Although it is not much, if we add the consultation of the letters, some advertising inquiry, or collect the data of a QR store, is more than enough information to create databases that thanks to unique identifiers, they can create a consumption profile of any user. Which, as we have already mentioned, is a cake highly desired by marketing companies and others.
Let's hope that with the boom that QR codes are having among consumers, the big browsers strengthen your security to avoid data “leaks” and ensure data privacy.
