IDEX Biometrics

IDEX Biometrics is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand IDEX Biometrics rather than just read about it. In short: IDEX Biometrics ASA is a Norwegian biometrics company, specialising in fingerprint imaging and fingerprint recognition technology. The company was founded in 1996 and is headquartered in Oslo, but its main operation is in the UK, with an office in Farnborough outside of London.

Key takeaways

IDEX Biometrics belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IDEX Biometrics to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IDEX Biometrics from memory before moving on to harder problems.

Reference excerpt

IDEX Biometrics ASA is a Norwegian biometrics company, specialising in fingerprint imaging and fingerprint recognition technology. The company was founded in 1996 and is headquartered in Oslo, but its main operation is in the UK, with an office in Farnborough outside of London. IDEX offers fingerprint sensor and biometric software for identity cards, banking cards, smart cards, access control, healthcare, IOT and other security solutions. Fingerprint recognition is one form of biometric identification, other examples being DNA, face recognition, iris recognition and retinal scan as well as identification based on behavioral patterns such as speaker recognition, keystroke dynamics and signature recognition.

Technology In 2010, IDEX SmartFinger Film was launched, a thin and flexible fingerprint sensor that allows the entire fingerprint sensor system to be built into a standard plastic card, such as credit cards, bank cards and national ID cards. Such system-on-card solutions with a microprocessor running biometric algorithms and storage of biometric user data embedded ensure that biometric data never leaves the card itself. This safeguards privacy. In the fall of 2012, IDEX changed its market focus. Until then, the company had emphasized the use of the technology in cards. The shift came after Apple acquired IDEX's competitor AuthenTec. This acquisition was a harbinger that fingerprint readers would be built into mobile phones, IDEX believed, which was reiterated when Apple introduced its iPhone with a fingerprint reader in the fall of 2013. Since then, several mobile manufacturers followed Apple's example and launched mobile phones with fingerprint solutions. IDEX's SmartFinger Film sensor technology is based on polymer process technologies and offers small, ultra-thin and flexible swipe fingerprint sensors. IDEX holds early patents for low-cost capacitive fingerprint sensors and has a cross-licence with Apple relating to this technology. IDEX has demonstrated mobile phone-related technology implementations running on an Android platform, as well as a technology concept for fingerprint sensors built into the cover glass of mobile phones. Finger recognition solutions for Apple iPhone and iPad using SmartFinger have been launched. IDEX's technology has also been integrated in biometric ISO-compliant cards. Fingerprint-based authentication of payment cards has gradually become the main focus of the company's efforts to commercialize its technology. In March 2021, the company started shipping TrustedBio, a new generation of sensors specifically targeting the card market.

Global Partners IDEX has announced partnerships with global companies including Mastercard, IDEMIA, Chutian Dragon, Feitian, Goldpac, HED, Hengbao, Excelsecu, Infineon, and XH Smart Tech.

Worked examples

Example 1 — a first encounter with IDEX Biometrics

Start with the simplest possible case. Write down what IDEX Biometrics claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to IDEX Biometrics before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about IDEX Biometrics ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of IDEX Biometrics

In research: IDEX Biometrics appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses IDEX Biometrics in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: IDEX Biometrics is common in secondary-school and first-year university syllabi. It links to neighbouring topics Access control software, Biometrics, Biometrics software, so understanding it makes those chapters shorter.
In everyday life: Look for IDEX Biometrics outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
