Hand Geometry biometrics is based on the geometric shape of the hand
- size of the palm, length and width of the fingers, distance between the knuckles, etc
|

What are advantages and disadvantages of Hand Geometry?
|
|
| |
Advantages of Hand Geometry Biometrics:
- Simple, relatively easy to use and inexpensive
- Hand geometry data is easier to collect, unlike the fingerprints
where a good frictional skin is required by imaging systems, and retinal data
where special lighting is required
- Environmental factors, such as, dry weather that causes the drying of the skin is not an issue
- Usually considered less intrusive than fingerprints, retinal, etc
Disadvantages of Hand Geometry Biometrics:
- The hand geometry is not unique and cannot be used in identification systems
- Not ideal for growing children
- Jewelry (rings, etc), limited dexterity (arthritis, etc) etc may pose a challenge
in extracting the hand geometry information
- The data size of hand geometry biometrics is large and is not ideal for using it in embedded systems
