Question 1

What is meant by biometric identification?

Answer

Biometric identification is a system of indentifying automatically individual physiological or behavioral characteristics, being based on the recognition of the true characteristics of an individual rather than the holder's memorisation of passwords, personal identification code pin, keys, passes, magnetic cards, IC cards etc. Passwords, cards, keys etc. can lost, stolen or be copied thus compromising security. These objects do not prove the user's true identity, therefore biometric technology, by being based on inherent characteristics is a more secure form of identification. In the field of biometrics, fingerprints are the most commonly used feature.

Question 2

Why do we use fingerprint recognition?

Answer

In the field of biometrics, areas for personal recognition include fingerprints, iris, palms (shape and palm prints), sound patterns etc. As for behavioural aspects these could include signatures. However, the most commonly used is fingerprint, mainly because it has the following advantages:

  1. Has legal basis, reliability and non-repudiation in law.
  2. Never changes in ones life.
  3. Low-cost, smaller image drawing devices.
  4. Skillful identification technology.
  5. Convenient - can use 10 fingers.

Question 3

Where can TrueSecure's 3D Fingerprint solutions be applied?

Answer

TrueSecure™ provides a variety of "optical touch fingerprint recognition" products. Owing to their flat touch panels, they are very suitable to meet the needs of individual privacy and home security as well as company confidential document preservation.

Divided into three main areas:

  1. Personal computers, portable computers and related computer peripherals and other applications, such as: AIO computers, desktop computers, notebook computers, mini book computer, computer keyboard, mouse, flash drives, fingerprint reader, hard disk … and so on.
  2. Mobile phones and personal assistants, wireless network security mechanisms such as certification of the related applications, such as: PDA, smart phones, network authentication, the security of online games ... and other authentication mechanisms.
  3. Independent access control system related applications, such as: smart cards, electronic door locks, access control systems, automotive electronic locks, electronic cash registers ... and so on.

Question 4

How is TrueSecure™ 3D fingerprint technology used?

Answer

TrueSecure™ uses optical touch fingerprint recognition technology. As the sensor is on a flat surface, simply resting ones finger gently on the sensor will start the fingerprint acquisition module. This will obtain the fingerprint image, after which the fingerprint will be converted into a digital format, and then processed for fingerprint matching to implement an authentication process.

Question 5

What are the advantages of TrueSecure™ 3D fingerprint technology in consumer products?

Answer

Consumer products using TrueSecure™ products have the following advantages:

  1. Easy touch without learning, easy to login.
  2. Ultra thin optical fingerprint identification module which can be applied for use in many handheld devices.
  3. Special surface treatments make recognition easier.
  4. Friction resistant and anti-static treatments may be applied to a variety of environments.
  5. High Safety factor - no need for high login rate to sacrifice security and to resist 2D fake fingerprints.

Question 6

Is the TrueSecure's application software is compatible with other company's products?

Answer

Yes it is. The TrueSecure's software is fully compatible with Windows. There is no problem with upgrading to newer versions. In addition, the same type of 3DTrueSecureTM ?Optical touch fingerprint recognition module?module can be used interchangeably.

Question 7

What is meant by FAR and FRR?

Answer

FAR stands for False Acceptance Rate. This is the probability of biometric systems obtaining erroneous identification of illegitimate users against legitimate users. It is therefore representative of the security level.
FRR stands for False Rejection Rate. This is the probability of biometric systems obtaining erroneous identification of legitimate users against illegitimate users. It is therefore representative of the convenience level.
The TrueSecureTM fingerprint modules have a FAR of <0.0001and a FRR of 0.01% The exact value depends on the type.
