Description
| BL-5139 | DOOR ACCESS CONTROL SYSTEM USING PALM VEIN RECOGNITION 1u101787 | 5 [0001] The present invention relates to a door access control system using palm | vein recognition, which belongs to the technical field of the third-generation | bio-recognition.
| Technical background | [0002] A door access control management system is a digital entry and exit control — system that can control the entry and exit of persons, and can also control the | behavior of persons in the building and sensitive areas, and accurately record and | statistically manage data. It mainly solves the safety problems of important places | 15 such as enterprises, institutions, schools, communities, offices and so on. Control | devices such as access control controllers and password keyboards are installed at | the building entrances, elevators and so on. To enter, a resident must have a card 3 or enter a correct password, or press a special biological password to be approved. | The door access control management system can effectively manage the opening | 20 and closing of the door, ensure that the authorized persons can freely enter and | exit, and restrict the entry of unauthorized persons.
| [0003] Door access control and security systems are used to protect people and | property, so the system itself must be safe. High security mentioned here refers to ! 25 the natural or quasi-natural properties of the product or system. It should ensure | the safety of the operation of the equipment and system and the safety of the | operator. For example, the equipment and system itself must be protected against | high temperature, low temperature, heat, smoke, mold, and rain, and must be | protected against radiation, electromagnetic interference (electromagnetic | 30 compatibility), impact, collision, drop and so on. The safety of the operation of the | equipment and system also includes fire protection, lightning protection, explosion | protection, electric shock prevention, and so on. On the other hand, the door | access control and security system should also have the function of preventing | man-made destruction, for example, having a protection shell against damage, and
| having anti-disassembly alarming, short circuit prevention and opening prevention. lu101787 | [0004] In the prior art, most of them use card management, the more advanced | ones use the biotechnology for verification management, and the palm vein | 5 recognition biotechnology has just developed in this field.
When the palm vein is | used for identity authentication, image features of the palm vein are acquired, and | they refer to the features that exist only in living body.
In this system, the vein | image features cannot be obtained from a palm of a non-living body, so it cannot be | recognized.
Therefore, it cannot be falsified.
When the palm vein is used for identity | 10 authentication, the vein image features inside the palm are obtained instead of the | image features on the palm surface.
Therefore, there is no recognition obstacle | caused by damage, abrasion, dryness, too wetness or the like on the palm surface. | When the palm vein is used for identity authentication, and the palm vein image is | acquired, the palm does not need to be in contact with the equipment, and it can be | 15 recognized by gently placing it.
This method does not have the unsanitary problems when the hand touches the equipment and the safety problems caused . by the palm surface features may be copied, and avoids the psychological | discomfort as the subject of the review, and at the same time, it will not be | unrecognizable after being contaminated by dirt.
Because the vein is located inside | 20 the palm, the influence of external factors such as temperature can be ignored, and | the palm vein method is suitable for almost all users.
The user acceptance degree | is good.
In addition to not requiring direct contact with the surface of the scanner, | this non-invasive scanning process is simple and natural, and alleviates the user's | resistance to possible concerns due to hygienic or troublesome use.
Due to the | 25 features in the previous three aspects of living body recognition, internal features | and non-contact, it is ensured that the palm vein features of the user are difficult to | be forged.
Therefore, the palm vein recognition system has a high security level, | and is particularly suitable for use in places with high security requirements. | However, the following problems still need to be solved in the prior art: (1) lt | 30 belongs to internal physiological features, does not wear out, is more difficult to | counterfeit, and has high security. (2) The features of blood vessels are usually | more obvious, easy to identify, and good anti-interference. (3) Non-contact | measurement can be realized, with good hygienicity and easy for users to accept. | (4) It is not easily affected by scratches or oil stains on the hand surface.
| Accordingly, the above technology has the following disadvantages: the acquisitionu101787 | equipment has special requirements, the design is relatively complicated, and the | manufacturing cost is high.
| 5 Summary of the invention | [0005] An objective of the present invention.
