Today, it is possible to verify our identity using a selfie, our voice or by placing our finger on the fingerprint reader of our mobile phone. Using those features that make us unique is a simple, secure way to access online banking services.
Human beings have physical characteristics that make each of us unique and serve to differentiate us. We are talking of unrepeatable features such as our facial features, fingerprints and voice. These types of features are called biometric data and they are becoming increasingly important when it comes to security in digital banking.
Just as we can identify our family and friends by simply seeing or hearing them, technology has managed to endow devices such as mobile phones, computers, tablets or video door phones with the same ability. This protects private data and physical and virtual facilities from access by third parties.
As we have said, biometrics uses those unique, non-transferable features of the human being, so the authentication of security systems consists in creating and saving a model or data map that represents the user exclusively and serves to confirm their identity when they request access, whether to physical or virtual spaces.
Since antiquity, security has been one of society’s major concerns. On Openbank’s blog you can find content that reviews how biometric identifiers have evolved over the course of history.
Examples of biometric authentication in digital banking
In the banking sector, the use of these biometric authentication systems represents a step forward in the protection of user data, for example by replacing or strengthening traditional alphanumeric passwords. They also serve as a reliable, fast and convenient method of verification when using or purchasing products and services. Here are some examples:
Advantages of biometric authentication
Biometric identification in the digital banking sector has several advantages. Convenience and simplicity of use is undoubtedly one of them. Whether it’s placing our finger on a reader, taking a photograph or simply speaking over the phone, none of these actions involves any great difficulty, as could happen with passwords or codes, which need to be remembered.
As no two fingerprints, faces or voices are identical, the security of this type of identification is greater. It is also a method that significantly reduces the chances of suffering crimes such as phishing, a fraudulent practice with which cybercriminals seek to access our personal data by sending e-mails.
Lastly, one of the advantages of biometric security is its continuous innovation: as technology advances, so do authentication methods. For example, one of the most recent steps in this direction is behavioural biometrics, which takes into account a combination of factors to identify the legitimacy of banking customers’ operations, such as how they type on the keyboard, the locations from which they frequently perform operations or their purchasing habits.
