The iris pattern is considered lifelong.
Unique features of the iris are: freckles, rings, rifts, pits, striations, fibers, filaments, furrows, vasculature and coronas.
Voice, signature and retina patterns are more likely to change over time, thus are not as suitable for authentication over a long period of time without needing re- enrollment.

Of the four biometric parameters mentioned, iris pattern is better suited for authentication use over a long period of time.
Iris pattern recognition is based on the unique patterns in the colored part of the eye. It is a very stable biometric parameter that remains constant over a long period of time, even decades. This is due to the fact that the iris is protected by the cornea and aqueous humor, which means it is less affected by external factors such as aging, injury, or disease. Iris recognition technology is also highly accurate, with a low false acceptance rate (FAR) and false rejection rate (FRR).
Voice pattern authentication is less reliable over a long period of time, as it can be affected by factors such as age, illness, and changes in the environment. Additionally, voice patterns can be easily spoofed or imitated, making them less secure than other biometric parameters.
Signature dynamics, which involves analyzing the way a person signs their name, is also less reliable over time. Signature dynamics can change over time due to factors such as injury or illness, or even just changes in handwriting habits. This can make it more difficult to accurately authenticate an individual using this parameter.
Retina pattern recognition, which uses the unique pattern of blood vessels in the back of the eye, is also less suited for long-term authentication. While the retina pattern is stable and unique, it can be affected by factors such as injury or disease, making it less reliable over time. Additionally, the process of capturing a retina scan can be uncomfortable for some individuals, making it less practical for widespread use.
In summary, of the four biometric parameters mentioned, iris pattern is the most reliable and stable for authentication use over a long period of time, due to its stability, accuracy, and resistance to external factors.
