Fingerprint recognition and iris scanning are the best known forms of biometric security. In recent years, facial recognition, fingerprint recognition, palmprint recognition, and vein pattern recognition have been gaining popularity. In this paper, we will discuss the advantages and disadvantages of all these different technologies.
Comparison of the differences between 5 biometric modes
1. Fingerprint recognition
Identification systems based on fingerprint recognition look for specific features in a line pattern on the surface of the finger. The bifurcations, ridge ends and islands that make up this line pattern are stored in the form of an image.
Capturing an image with external features has the disadvantage that if we store the image in encoded form, the image can still be copied, using. An image is, after all, still an image and can therefore be compared. Analyzing from the theoretical principle, this method is possible to product the same code. Fingerprints can already be forged by relatively easy-to-acquire techniques. Another issue worth considering, and by no means meaningless, is that the finger presented for identification purposes does not necessarily still need to be attached to the body... ....
In addition, some line patterns are so similar that in practice this may lead to a high rate of false acceptance. Fingerprints can also wear out with age, for example, if you do a lot of DIY or a particular kind of work. As a result, some people may find that their fingerprints are unrecognizable (false rejections ) or even unrecordable. There is even a genetic disorder that causes people to be born without fingerprints!
On the other hand, fingerprint recognition is already familiar to most of the public and is therefore accepted by a large number of users. This technology is relatively cheap and easy to use compared to other technologies.. However, it should be noted that the quality of different fingerprint recognition systems varies widely, with significant differences between systems in terms of false acceptance and false rejection rates.
Biometric spoofing is the appearance of a forged biometric with the purpose of being identified as another person. this may involve the use of duplicate fingerprints or contact lenses with forged iris patterns. the risk of spoofing is mainly manifested in the form of biometric security based on surface external features.
2. Facial recognition
Facial recognition systems determine a match by analyzing the shape and position of different parts of the face. surface features such as skin are sometimes taken into account.
Face security recognition is a branch of face detection technology that is used to identify multiple faces that may appear in complex images. This technology has evolved rapidly in recent years, so it is a good candidate if a system is needed for remote recognition. Another benefit is that the technology can "negatively identify", or exclude, faces, making it easier to scan for suspicious people in a crowd.
However, facial recognition also has some obvious drawbacks. For example, the technology focuses primarily on the face itself, i.e., from the hairline down. As a result, a person usually has to look directly into the camera in order to be recognized. Although this technology is still in a rapid stage of development, the level of security it currently provides is not yet comparable to iris scanning or vein pattern recognition.
3. Iris Recognition
When an iris scan is performed, the scanner reads the unique characteristics of the iris, which is then converted into an encryption (barcode). It is undeniable and well known that iris scanning - a more secure and faster biometric security technology - is especially important when working with infrared light for scanning
However, a recurring problem with the introduction of this technology is resistance from users. A considerable number of people have found their eye scanning a rather unpleasant experience. You also have to take a certain position so that the scanner can read your iris, which can cause discomfort. Another drawback that is often mentioned, but has not been well improved by the click, is the hygienic situation. In many systems, the user has to ask for the chin to be placed in the chin rest, which has been used by many people before this, but sterilized
Finally, it is important to remember that while iris scanning provides a high level of security, this may come at the expense of speed. Incidentally, a system has recently been developed that can read a person's iris from a (relatively short) distance.
4. Finger vein pattern recognition
In the case of vein pattern recognition, the end points and bifurcations of the finger veins are captured in the form of images, digitized and converted into encrypted codes. This method, combined with the fact that the veins are found under the skin rather than on the surface, makes this technology much more secure than fingerprint-based identification, as For the user this method is both fast and convenient, fully satisfying the user's point of need.. This method becomes more expensive by analogy with other methods.
Another point to remember is that very cold fingers and "dead" fingers (such as those suffering from Raynaud's syndrome) are impossible or difficult to read using finger vein pattern recognition. However, perhaps the biggest drawback is that this technology is still relatively unknown.
5. Palm vein pattern recognition
This technology is also based on the recognition of unique vein patterns..Palm print recognition uses reference points that are not available in finger vein pattern recognition, making palm print recognition an increasingly simpler and more secure method of recognition.
This technology is currently not reproducible, and is therefore considered the best method of biometric security on the market today, on par with iris recognition.. Palm scanning is fast and accurate, and provides a high level of user convenience.
Palm vein pattern recognition based access control systems are relatively expensive. This system is used by the government, judicial system and banking sector, etc., which have strict security requirements.
But this method usually confuses hand geometry, which is a point we should be aware of.
