[ Huaqiang Security Network News ] Biometric technology is a relatively new technology. It is still in its infancy. However, it is still necessary for individuals to master the relevant knowledge and clear the basic concepts of biometric technology. 
Biometric (biometric):
Biometric Identification Technology: The use of human biometrics for identity authentication. It is based on (1) the human biometrics are different (2) the two points that can be measured or automatically identified and verified. Human biometrics include physiological characteristics or behavioral patterns. Physiological characteristics include hand shape, fingerprint, face shape, iris, retina, pulse, auricle, etc. The behavioral characteristics include signature, sound, and button strength.
Question: 1. Is biometric recognition more likely to be called person recognition or human recognition? 2. There are many differences in the commonality between different biometric technologies. Should these technologies be completely independent?
Fingerprint recognition:
Fingerprint recognition is a technique for authenticating a human identity using human fingerprint characteristics. Fingerprint technology is the most mature and widely used in all biometric technologies.
Question: 1. Is fingerprint recognition technology really mature? How should the incorporation of fingerprints be included in the relevant system? 2. What is the most promising future of fingerprint recognition?
Algorithms Algorithms are computer software terms that primarily refer to the specific steps and methods required to accomplish a task. That is to say, given the initial state or input data, the finite number of operations of the computer program can be used to obtain the desired result. Algorithms often contain repeated steps and some comparison or logic decisions. If an algorithm is flawed or not suitable for a problem, executing this algorithm will not solve the problem.
The algorithm mentioned in the field of biometrics is essentially the application of software algorithms in the field. The fingerprint recognition algorithm is taken as an example. The core algorithms include fingerprint matching algorithm, fuzzy fingerprint image processing algorithm, fingerprint feature classification, positioning and extraction algorithm. And the fingerprint stitching algorithm.
Question: 1. Should the algorithm be the core of biometrics? 2. Chinese companies frequently get good rankings in the fingerprint algorithm contest. Does it mean that we have reached the world level in this respect?
Fingerprint Sensor In general, a sensor is a device that converts a measured measurement into a determinable relationship with an easy-to-handle power signal for a purpose of measurement. The fingerprint sensor is a device for measuring the electrical signal of the finger. At present, fingerprint sensors are of different types such as optical type, crystal capacitance type and the like.
Question: For Chinese companies, where are the main technical challenges of fingerprint sensors?
Identity authentication (identification)
To be straightforward, it is a way of authenticating a person who wants to obtain an identity by some means or means. For example, you can use the ID card or account/password to authenticate whether you are a legitimate user of this system.
Question: What is the current identity authentication technology? What is its classification criteria?
AFIS (Automatic Fingerprint Identification System)
AFIS (Automaed Fingerprint Idenification System) refers to the computer processing the input fingerprint image to realize the classification, positioning, extraction form and detail features of the fingerprint, and then the fingerprint comparison and recognition according to the extracted features.
Question: AFIS is traditionally a fingerprint identification system for the police field. Is there still a need for the word today?
In terms of information security , information security is to ensure the validity and security of electronic information. Information security involves the confidentiality of information, integrity (Integrity), availability, and controllability. Confidentiality is a passive attack against an opponent, ensuring that information is not leaked to unauthorized people. Integrity is against active attacks by opponents, preventing unauthorized tampering of information. Usability is about ensuring that information and information systems are actually used by authorized users. Controllability is the implementation of security monitoring of information and information systems.
Question: 1. Should the application of biometric technology be focused on information security? 2. Should the future use information security technology to lead biometrics or biometrics to guide information security technologies?
Encryption and encryption technology mainly refers to a technical means used to protect data from leakage. It mainly turns important data into garbled (encrypted) transmission, and then restores (decrypts) by the same or different means after reaching the destination. ). Encryption technology consists of two elements: the algorithm and the key. An algorithm is a combination of ordinary text (or understandable information) with a set of numbers (keys) to produce an incomprehensible ciphertext. An key is an algorithm used to encode and decode data.
Question: 1. Is the file encryption function necessary for fingerprint identification applications? 2. Does its existence indicate that the simple fingerprint identification application is too simple to meet the user's needs?
The meaning of fingerprint attendance fingerprint attendance is very clear: use the fingerprint instead of swiping to record the attendance of employees. The reason why fingerprint attendance is listed as one of the ten basic concepts of biometric identification is because of its importance. It is said that fingerprint attendance has occupied 60% of the entire Chinese fingerprint identification market, and fingerprint recognition accounts for 90% of the market. Share. The fingerprint attendance system is a management system that implements attendance registration and attendance management by using a fingerprint identification device and a computer system.
