Biometric Identifier

Biometric Identifier
A Personal biological (anatomical or physicological) or behavioural characteristic which can be used to establish a person's identity by comparing it with stored reference data. Traditionally, the most popular biometric identifier is the fingerprint. Other frequently used biometric identifier include the facial image, iris image and hand geometry. Biometric identifier can be used for biometric recognition processes such as facial and iris recognition. The method of measuring biometric identifier is known as "biometrics".
In e-passports, biometric data is stored in an embedded microchip (integrated circuit). Pursuant to ICAO (International Civil Aviation Organization) specifications a Microchip-contactless as a minimum requirement - stores the data visually displayed in the MRZ (Machine Readable Zone) of the biodata page of the passport and the facial image as the interoperable biometric identifier. Other biometric identifiers, e.g. fingerprint or iris images, can be added optionally. The biometric data on the chip can be compared with the document holder's biometric characteristics, using a biometric system. As a safeguard, a digital signature is used to protect the authenticity and the integrity of the stored data.



Biometric Identifier
Bentuk biologis dari seseorang (anatomi dan fisiologi) atau sifat karakter yang bisa digunakan untuk membuat sebuah identitas dengan cara membandingkan data yang ada dan data yang telah disimpan. Sejak dahulu, Biometric Identifier yang paling terkenal adalah sidik jari. Teknik yang lain yang menggunakan Biometric Identifier adalah scan wajah, dan bentuk tangan. Biometric Identifier bisa juga digunakan sebagai proses pengenal seperti pengenal wajah. Metode pengukur Biometric Identifier dikenal sebagai Biometrics.
e-Passport
Pada e-Passport, data biometric disimpan dalam sebuah microchip. Berdasarkan ICAO (International Civil Aviation Organization) spesifikasi adalah microchip contactless menyimpan data visual yang dapat ditampilkan di MRZ (Machine Readable Zone) berupa halaman passport berisi biodatan dan facial image sebagai Biometric Identifier. Jenis Biometric Identifier seperti sidik jari bisa dimasukan sebagai tambahan.
Biometric data yang tersimpan dalam chip bisa dibandingkan dengan pemiliknya melalui karakteristik biometrik, menggunakan sistem biometric. Sebagai pelindung, sebuah tanda digital digunakan untuk menjaga keaslian dan keutuhan dari data yang tersimpan.

Water Transfer Printing.

Now the water transfer printing method more popular, especially for Helmet Printing, Mug and other material printing with round shape. Water Transfer Printing is very easy to transfer to other media like helmet, so the process more efficient. Water Transfer Printing also called as curve coating printing (a printing method for print at surface that is not flat) this method overcomes the problem facing offset printing that can't reach the tongued and grooved face and the disadvantage from paying higher expense for the equipment. Water Transfer Printing process can be applied to surface of the materials such as ceramic, wood, plastic, fiber, stone, hardware, glass, metal, etc. The cost for applied with this method is relative low, while their added value multiples.

Forum Percetakan | The Offset Printing

The Offset Printing Offset printing is the most commonly used printing method today. More than 50% of all printing jobs is using offset printing technique. Offset printing works with a simple manner. Offset printing uses three cylinder to transfer the printed image to the substrate. First cylinder in offset printing is mounted with offset printing plate. The image on offset printing plate is readable. The first cylinder inked and transfer image onto the rubber blanket (second cylinder). The image in rubber blanket is unreadable. After that image transferred from rubber blanket onto third cylinder or the substrate. Substrate is mounted on the third cylinder or The Impression Cylinder. The image in Impression Cylinder becomes readable again. Image in offset printing have a unique characteristic, the printed image and non-printed image are on same surface level. The printing method used a chemical process that ink and water not mixed from a single surface level. In fact, offset printin...

Hello all visitor, thanks for visit to our blog. As you know, there are no update since last three year and we don't have any topic to discuss in this world. All has been done. You can find anything you need to know about technique, modified method and tools to make your own company who run in printing business.
