FINGERPRINTS AND TECHNOLOGY
FINGERPRINTS AND TECHNOLOGY
Introduction
The human fingerprint is a unique biometric identifier that is used to secure access to personal and sensitive data. It is composed of patterns of ridges and valleys that form on the fingertips and palms. Fingerprints are unique to individuals, and they are considered one of the most reliable forms of biometric authentication available. The use of fingerprints is becoming increasingly popular in the field of security, as it is an effective way to prevent unauthorized access to protected data and systems.
Principle
Human fingerprints are unique, durable, making them suitable as long-term markers of human identity. They have played an important role in the history of forensic science and personal identification or security.
What is the “fingerprints” of your product? Is there any unique surface and structural characteristics of your product which differ from the competitive products?
Nowadays many products, especially consumer products, often present themselves as a brand with certain optical appearance, haptics surface features and scents to attract customers.
The touch and feel on the product from human beings is powerful. Detailed understanding and enhancing the aesthetic portion of the total “feel” is helpful in the consumer product design.
The “fingerprints” of many consumer products could bring various benefits in the field of:
- Product surface design: create unique product branding features as identification
- Used as a quality assurance protocol during manufacturing stages: provide “Green”or “ Red” light during the production
Main features of human Fingertip:
- viscoelastic
- curved structure
- rough surface
- inhomogeneous and nonlinear
- containing dandruff, dirt, swear, fat, lotion, cream
- Standard silicone stamp represents the viscoelasticity of the fingertip;
- Standard fabric/textile represents the rough structure and texture of the fingertip;
- Standard liquid can be artificial sweat, hand cream and many more;
- Dynamic load is applied via the piston/stamp onto the sample surface with a fixed 45o angle
