Abstract

A method of estimating a range of age of a subject, the method comprising: a) making at least one measurement of epidermal ridges of the subject; and b) estimating at least a range of age of the subject, using the measurements of the epidermal ridges, without using the measurements to identify the subject.

Claims

1. A method of estimating a range of age of a subject, the method comprising:

a) making at least one measurement of epidermal ridges of the subject; and

b) estimating at least a range of age of the subject, using the measurements of the epidermal ridges, without using the measurements to identify the subject.

2. A method according to claim 1, also including scanning the epidermal ridges to produce a scanned image, wherein making the measurement comprises analyzing the scanned image.

3. A method according to claim 1, wherein the measurement comprises a measurement of an average distance between adjacent epidermal ridges.

4. A method according to claim 3, wherein the epidermal ridges are on a finger pad.

5. A method according to claim 4, wherein the finger pad is an index finger pad, and the subject is estimated to be under 17 years old if an average distance between adjacent ridges is less than 0.477 mm when the index finger is pressed against a surface.

6. A method according to claim 4, wherein the finger pad is an index finger pad, and the subject is estimated to be at least 17 years old if an average distance between adjacent ridges is at least 0.477 mm when the index finger is pressed against a surface.

7. A method according to claim 3, wherein the average distance between adjacent ridges is an average over ridges in a region of the skin where the ridges are substantially straight.

8. A method according to claim 3, wherein estimating the range of age comprises using other biometric data of the subject, combined with the average distance between adjacent ridges.

9. A method according to claim 8, wherein the other biometric data comprises a measure of the width of a finger pad.

10. A method according to claim 9, wherein the subject is estimated to be at least 17 years old if the product of the average distance between adjacent ridges of the index finger pad, and the width of the index finger pad, is greater than 6.60 mm² when the index finger is pressed against a surface.

11. A method according to claim 9, wherein the subject is estimated to be less than 17 years old if the product of the average distance between adjacent ridges of the index finger pad, and the width of the index finger pad, is less than 6.60 mm² when the index finger is pressed against a surface.

12. A method according to claim 8, wherein the other biometric data comprises data of the voice of the subject.

13. A method according to claim 1, wherein the subject is estimated to be an adult or not an adult, depending on whether a measure of the epidermal ridges on a subject is greater than or less than a value, the value being selected according to distributions of said measure for a population of adults and for a population of youths.

14. A method according to claim 13, wherein at least 70% of the population of adults have said measure greater than the value.

15. A method according to claim 13, wherein at least 70% of the population of youths have said measure less than the value.

16. A method according to claim 13, wherein the percentage of the population of youths who have said measure less than the value is substantially equal to the percentage of the population of adults who have said measure greater than the value.

17. A method according to claim 13, wherein the population of youths is between 13 and 16 years old.

18. A method according to claim 13, wherein the measure is an average distance between adjacent epidermal ridges on one of the finger pads.

19. A method according to claim 13, wherein the measure is the product of an average distance between adjacent epidermal ridges on one of the finger pads and a width of said finger pad.

20. A method according to claim 1, also including deciding whether to permit or deny the subject access to a resource, depending on the estimated range of age.

21. A method according to claim 20, wherein the resource comprises a pornographic website.

22. A method according to claim 20, wherein the resource comprises a gambling website.

23. A method according to claim 20, wherein the resource comprises an internet site for children, and the subject is denied access if the estimated range of age is greater than a maximum age.

24. Apparatus for estimating a range of age of a subject, the apparatus comprising:

a) a data acquisition device adapted to obtain data of the subject'"'"'s epidermal ridges; and

b) an analyzer adapted to obtain at least one measurement of an average distance between adjacent epidermal ridges by analyzing the data and to estimate the range of age of the subject by analyzing the at least one measurements.

25. Apparatus according to claim 24, wherein the data acquisition device has a resolution that is worse than 0.05 mm.

26. Apparatus according to claim 25, wherein the data acquisition device has a resolution that is worse than 0.1 mm.

27. A system for controlling access to a resource by users under a minimum age for access, the system comprising:

a) apparatus according to claim 24, adapted to estimate the range of age of each of the users; and

b) a controller, adapted to deny access to a user, according to a relationship between the estimated range of age of the user, and the minimum age for access.

28. A system according to claim 27, wherein the apparatus is also adapted to establish the identity of a user by comparing imaging data of the user'"'"'s finger pad to a database of finger pad ridge patterns, and the controller is adapted to deny access to the user, according to the estimated range of age of the user, or the identity established for the user, or both.

29. A system according to claim 27, wherein the apparatus is adapted to repeatedly estimate the age of each user while said user is using the resource, and the controller is adapted to terminate access by said user according to a relationship between an estimated range of age of the user made while the user is using the resource and the minimum age for access.
