This iris scanning method is said to be a reliable alternative to the old ID system for security purposes and easy identification of crime perpetuators, especially on airports, on restricted areas, and on release and booking of prisoners.
The process will involve scanning the resident’s eye’s image, fingerprints, a photo and signature.
We are confident that this system will be 99 per cent reliable, "The legal, technical and financial conditions are ready to start the process of issuing this identity document," according to Felipe Zamora, who is responsible for legal affairs at the Mexican interior ministry.
This process will not initiate at once as the cost will be a huge amount of approximately $25 million U.S. The card will be activated for adults starting 2013.
Although, this innovation in the Mexican law is on step higher on adapting and maximizing how technology can help the nation towards progress and protecting its people against crimes and quick identification of criminals and suspects whereabouts; but many have criticized and many are against to this move that the government made including the National Human Rights Commission.
The National Human Rights Commission feared that this iris scan system could violate individual rights and privacy.
Let us weigh then that advantages and disadvantages of this system with regard to security purposes:
Wiki have listed down in details the advantages and disadvantages about this iris scanning method:
Advantages:
* It is an internal organ that is well protected against damage and wear by a highly transparent and sensitive membrane (the cornea). This distinguishes it from fingerprints, which can be difficult to recognize after years of certain types of manual labor.
* The iris is mostly flat, and its geometric configuration is only controlled by two complementary muscles (the sphincter pupillae and dilator pupillae) that control the diameter of the pupil. This makes the iris shape far more predictable than, for instance, that of the face.
* The iris has a fine texture that—like fingerprints—is determined randomly during embryonic gestation. Even genetically identical individuals have completely independent iris textures, whereas DNA (genetic "fingerprinting") is not unique for the about 0.2% of the human population who have a genetically identical twin.
* An iris scan is similar to taking a photograph and can be performed from about 10 cm to a few meters away. There is no need for the person to be identified to touch any equipment that has recently been touched by a stranger, thereby eliminating an objection that has been raised in some cultures against fingerprint scanners, where a finger has to touch a surface, or retinal scanning, where the eye can be brought very close to a lens (like looking into a microscope lens).
* Some[who?] argue that a focused digital photograph with an iris diameter of about 200 pixels contains much more long-term stable information than a fingerprint.
* While there are some medical and surgical procedures that can affect the colour and overall shape of the iris, the fine texture remains remarkably stable over many decades. Some iris identifications have succeeded over a period of about 30 years.
Disadvantages
* Iris scanning is a relatively new technology and is incompatible with the very substantial investment that the law enforcement and immigration authorities of some countries have already made into fingerprint recognition.
* Iris recognition is very difficult to perform at a distance larger than a few meters and if the person to be identified is not cooperating by holding the head still and looking into the camera. However, several academic institutions and biometric vendors are developing products that claim to be able to identify subjects at distances of up to 10 meters ("standoff iris" or "iris at a distance").
* As with other photographic biometric technologies, iris recognition is susceptible to poor image quality, with associated failure to enroll rates.
* As with other identification infrastructure (national residents databases, ID cards, etc.), civil rights activists have voiced concerns that iris-recognition technology might help governments to track individuals beyond their will.
Now, based on the above discussion, are you in favor of this or not?
