Signature vs. Biometric Signature: Understanding the Difference

Introduction to Biometrics and Signatures

A signature is not typically classified as a biometric. Biometrics refers to unique physical or behavioral characteristics used for identification and authentication such as fingerprints, facial recognition, iris scans, or voice patterns. While signatures can be used for verification purposes, e.g., in legal documents or banking, they are more related to a person's handwriting style rather than a unique biological trait. However, some advanced systems now analyze the dynamics of how a signature is made, like pressure, speed, and stroke order, which could incorporate biometric principles. However, this is not the same as traditional biometric identification methods.

Deep Dive into Biometric Signature Verification

Biometric Signature Verification authenticates the signer by measuring their handwritten signatures. A signature consists of exclusive biometric data such as the pressure, writing rhythm, pen inclination, acceleration, speed, curvature, position, and timestamp. This multifaceted approach makes biometric signature verification a robust method for security and accuracy.

Advantages of Biometric Signature Verification

Tracking Variations over Time: Biometric Signature Verification can track each person's natural fluctuations over time and easily determine forgery. As each person's signature tends to change over time, the Biometric Engine is able to adjust the personal profile to adapt to these changes regularly. This continuous learning process enhances the security of the verification process. Uniqueness in Every Use: Biometric signatures are unique in every use and always belong to a specific document. This makes it virtually impossible for a signature to be reused, unlike an imaged signature which can be easily copied and reused. Proven Legitimacy: Biometric signatures contain enough data that can help determine the authenticity of a signature, making them a reliable method for automated document and contract processing.

What’s the Real Difference Between a Biometric Signature and an Image of a Signature?

The main difference lies in the amount and type of biometric data captured and verified. An Imaged Signature captures only one type of biometric data: the curvature. On the other hand, a Biometric Signature captures up to five types of biometric data, which includes pressure, writing rhythm, pen inclination, acceleration, and speed. This vast range of data makes a Biometric Signature far more secure and reliable than an Image Signature.

Another significant disadvantage of an Image Signature is that it lacks sufficient information to prove its legitimacy. An Image Signature is an unverified copy of your original signature, and thus, it can be easily replicated. Biometric signatures, however, are unique every time they are used, ensuring high security and minimal risk of forgery.

Why Choose a Biometric Signature

Biometric signatures tend to be one of the safest ways to use automated documents and different contracts. They offer unparalleled security and accuracy, making them ideal for industries where the integrity of documents is crucial. In contrast, Image Signatures are prone to forgery and lack the necessary security features to guarantee the legitimacy of a document.

The benefits of using biometric signatures far outweigh the use of image signatures. With biometric signatures, you can ensure that the document being signed is the one intended and that the signer is who they claim to be. This level of security is essential in any business or legal context where the authenticity of documents is paramount.
