Description: A biometric signature is a unique representation of a person’s identity created using biometric data, such as the way one signs by hand, the pressure applied, speed, and rhythm of the stroke. This type of signature is considered an advanced form of authentication, as it combines physical and behavioral characteristics that are difficult to replicate. Unlike traditional signatures, which can be forged, biometric signatures offer an additional level of security by relying on intrinsic characteristics of the individual. Its implementation has become increasingly relevant in a world where information security is crucial, and it is used across various sectors, including banking, government, and healthcare. The biometric signature not only provides a means to verify a person’s identity but also facilitates processes like signing electronic documents, enhancing efficiency and security in digital transactions.
History: The idea of using biometric characteristics for identification dates back to the late 19th century when fingerprints began to be used in policing. However, the concept of biometric signature as we know it today began to develop in the 1990s with the advancement of digital technology and the need for more secure authentication methods. In 1994, the first commercial biometric signature system was introduced, which utilized the capture of handwritten signatures. Since then, the technology has evolved, incorporating more sophisticated methods such as voice recognition and facial identification.
Uses: Biometric signatures are primarily used in identity authentication for electronic transactions, such as signing digital contracts, authorizing online payments, and accessing secure systems. They are also applied in various sectors, including healthcare to ensure the privacy of medical records and in government for citizen identification in public services. Additionally, they are implemented in mobile devices to unlock phones and applications through the user’s signature.
Examples: A practical example of biometric signature is the use of digital tablets in sectors like banking, where customers sign documents with their handwritten signature, which is captured and stored as a biometric pattern. Another example is the use of electronic signature applications that require the user to sign with their finger on a touchscreen, allowing for secure identity verification. They are also used in access control systems, where the biometric signature is combined with other authentication methods, such as passwords or facial recognition.
