Biological identification: a piece of hair is enough to 'catch a picture'

It is about time you can throw away bank card withdrawals, supermarket payment cards, business cards . The new generation of testing equipment will 'look' at your hands to see exactly you Who is it, what is the habit? But danger is always lurking on you, because many personal information is in the hands of others.

After the September 11, 2001 event of the collapse of the World Trade Center (US) twin towers, the examination of identity through electronic biological parameters became a priority task. for security agencies in the world. Some countries have realized this. So what are its benefits and disadvantages?

The weakest point of a normal passport is only a portrait photo to be identified with the presence of its owner. Is there any other way to help compare it more accurately? Biological identification is an answer.

Finger and wrist

Since the 7th century, China and Japan have found that no one has fingerprints that match other people. And they applied a point measure to marriage papers as well as to identify criminals. Europe had not adopted this method until the second half of the 20th century, but in return, it completed it to a sophisticated and widespread level.

Today, just flick your finger into the scanner (optical or ultrasonic) you can prove your identity to enter the workplace, withdraw money at the bank, vote to vote . The only downside. of this method is that the machine is easily contaminated in the finger contact part, in addition, criminals can fake fingerprints.

Same principle, people also apply to the wrist. Honeywell's HandKey device identifies the shape (geometrie) of the wrist along with the structure of the fingers, which are parts that are not duplicated and difficult to fake.

People also create identification systems through photographs of blood vessels on the hands. Just put the palm on the Fujitsu PalmSecure machine. This method will gradually replace signing for withdrawal via bank account because the account holder, for many reasons such as mood, age, illness (parkinson, for example) will be hard to keep the original signature form of me

Eyes and face

Identity through the pupil and retina has become increasingly popular. Glasses, including contact lenses, do not interfere. Because of its almost absolute accuracy, offices need high security that is widely applied. The equipment is still being completed, it is possible to check the subject standing about half a meter away.

In addition, face recognition is also a matter of interest. There is an electronic device that recognizes the face even if the person has a hair, mustache, beard or head in front of the camera. There are 12 to 40 parameters to compare the structure of the face. This device is currently widely used.

DNA testing methods are now considered to be absolutely accurate. However, its disadvantage is that there must be a laboratory, waiting time for results, so only the medical and criminal fields apply.

The reverse of progress

All of the above methods contain 3 disadvantages:

First , identity systems are sometimes faulty, especially with low-cost devices, which contain few reference parameters. However the risk ratio is only one millionth.

Second , the object to be tested can be rejected, and must be replaced by other operations.

Thirdly , there are biological changes in subjects such as burns, eye diseases, sore throat that change the voice. Biological parameters cannot be absolutely secure either.

Is it worth it for us to take risks in exchange for a comfortable life? (Illustration)

The following example is eloquent proof: A hacker group called Germany's CCC stole identity information from the Minister of Interior Vonfrang Shsoyble, who strongly promoted the introduction of fingerprints into electronic passports, when he was talking at a university, accidentally left his fingerprint on a glass of water. And so his private information is disseminated on the Internet.

Even copying DNA is not difficult. People often leave their DNA traces on the mouth of an unwashed wash glass or those scattered hairs .

Electronic check

A new method of integrated identification in the world is being applied: Advanced standards and technologies are jointly implemented by the International Civil Aviation Association (ICAO). Accordingly, when going to any other country, everyone must present their passport, and an electronic chip in the form of a logo containing personal biological data attached to the passport.

The use of portraits is still common, but some countries are preparing to bring fingerprints and scans of their passport holders to the chip. Compared to photos, this chip is very hard to fake, even when the microprocessor circuit is changed, the original data is still held by the passport authorities.

Farewell to private life!

After each check when going through the airport gate, registering the hotel, reporting to the police . is once the personal data transferred to electronic storage facilities.

Even though we are not aware of it, we have left scattered personal data in many places, such as in the passport of the state, bank card, supermarket card, office entrance card. , then your own code, password, etc. And if something goes wrong, these data will be printed and disseminated. However, these data are often not connected, unless there is a professional investigation.

Biological identification helps us remove dozens of these cards. Just give the biometric identification card or put your finger on the identification device. Conversely, when someone has access to your key, they will immediately know about your private life: Where to shop, what supermarket to shop for, where to go on vacation, work from Which hour is coming . It will be dangerous if these data fall into the hands of criminals.

Even if personal data is absolutely confidential, who can ensure that authorities will only use them for the benefit of all citizens? If a link in the government system is weak, the information will be used to eliminate an opponent, to resolve political disputes . In addition, governments do not exist forever, there are change due to voting or coup. At that time, the database of individuals would be taken advantage of to pay each other in the name of 'for a high purpose'.

A question arises: Is it worth taking risks to exchange for a comfortable life? While we are hesitating, technical progress does not stop. We only have to accept and use it.
