Biometric passport is the new identification of technologically sound world.
What is Biometric passport? A biometric passport is an electronic passport containing biometric information about the travelers who are traveling from one country to another country. It is also called e passport because the processing and authenticated identification of the travelers are done by the help of internet. This passport introduces a new path of technology. It looks very attractive and smart. It contains a microprocessor chip or computer chip and an antenna located in the back or front side of the passport. Both are included in the passport to maintain communication and power supply. Documentation of the document and characterization of the chip are done by international civil aviation organization. Critical information of the passport is stored in the chip and printed out in the data page of the passport. It is controlled electronically. So there is no way to copy or forge the passport in a wrong way if all the safety mechanisms are fully activated.

There are actually three types of identification reports which are included in the passport. They are DNA fingerprint recognition, facial recognition, and iris recognition. Retinal scan is also involved with this process. That information is stored in the contact less chip of the passport. It has 32 kilobytes storage capacity to store that information. But passport card of USA is not this type of biometric passport. This passport is used in a small number of nations. The four basic parts of this contact less smart biometric passport are data access control system, a microprocessor chip, communication security and other programmes to manage many functions of the passport.

Biometric passports are furnished by their own security system. This security system work to detect and avoid threat. Non traceable random chip numbers are included in the chip electronically. So every passport has random identification number. When a reader gives the date of birth, the document number and the expiry date, these are derived to a key number into the machine readable zone which shows the extra information on the screen. In this process a reader can read the chip. This work is controlled by basic access control. Passive authentication or PA regulates any manipulation in the chip data. So PA is a mandatory matter for a biometric passport. Any copy of the biometric passport is detected by active authentication or AA. A private key is added to AA of every biometric passport which cannot be copied. Extended access control system controls the legality of both the reader and the chip. Shielding of the chip prevents the unauthorized reading of the chip. A thin metal cover is added to shield the passport to prevent unauthorized reading.

Privacy makers of many countries protest about the smaller amount of information included in the biometric passport. Their main objection is that biometric passport is working in wireless card system. So its vulnerability is a concern for them. An ID number is sufficient to get their information without their physical attendance. If in any way the security system collapses, it cannot be worked in a safe way.

Everything in the world has its positive and negative sides. Our expectation is to overcome the negative aspect in biometric passport.

It is one of the great information for the Biometric passport for the new identification it is really helpful nowadays because there are lots of advance facilities are available for the biometric passport. There are mainly three types of identification such as fingerprint recognition, facial recognition, and iris recognition. These three are the most important.

A Thought - 10 years from now when we will enter in a store, an electronic greeter will be standing, scanning our iris and face. Then instantly comparing us against some database and detect your name, then say .. "Mr John.. Welcome. I have special deals for you ...".

Biometric passport would be the fresh detection of technologically noise planet is one of the great work with improvement of man health and fitness. I really hope to get additional understanding of biotechnology by way of this online community.

Informative post shared here. Biometric passport has intricately designed passport pages,complex watermarks and data chips.This chip contains crucial information such as digital signature data,which helps in authenticating passport.Biometric consider more reliable and personal than a passport photo,as it uses personal trait such as facial or eye maps and fingerprint as primary identification features.

Is it sort of smart card? What is difference in e-passport and smart card from biometrics point of view?

In my personal view, Biometric term in itself means "Measures of Biological Paramters". So any smart card/ passport / password / bank account / aadhar card (Unique IDs) that claim to be Biometric cards/Passwords/and so on; actually signify the fact that their security measures involve coding/storing and verification of Biometric data (i.e Biological data of the user: viz his iris scan/finger prints/DNA fingerprint etc).
