Ⅰ The Introduction of Iris Toxicology Scan
The iris drugs detector uses AI automatic learning training algorithm to detect whether a person uses drugs or not by the changes of iris (pigment, texture) and pupil (pupil enlargement and reduction values based on spectral mapping principle). After a large number of repeated training and correction of data, the recognition accuracy was improved, and the innovation of iris drugs detection algorithm was first achieved.
The instrument detector can quickly and accurately determine whether a person takes drugs through the detection and analysis of the iris sample. It is easy to carry and operate. Put the detector on the tested person’s eyes to collect and identify the iris, and analyzes whether the tested person takes drugs through the built-in iris AI drugs detection algorithm. The detection can be completed within 10s, with high efficiency and accurate results, which can be widely used in the screening of various anti drug sites.
Ⅱ Technical Principles of Iris Toxicology Scan
The structure of human eye consists of sclera, iris and pupil. The sclera is the white part around the eyeball, accounting for about 30% of the total area; The center of the eye is the pupil, accounting for about 5%; The iris is located between the sclera and the pupil and contains the richest texture information, accounting for 65%. Through spectral mapping, the pupil constriction occurs when the pupilary sphincter in the iris contracts; When the light becomes weak, the dilator muscle of iris contracts, and the pupil becomes larger.
After encountering light stimulation, the physiological characteristics curve of the eyes of a long-term drug user is inconsistent with that of a normal people. As the intensity of light changes, the changes of drug users’ pupil and iris, and the specific presentation of iris texture also differ from that of normal people. According to the comprehensive physiological characteristics of the eyes, the detector calculates the physiological curve to analyze whether there is drug use.
Ⅲ Core Functions of Iris Toxicology Scan
1.One click quick screening
Detect 99% of the drugs on the market, including traditional drugs, new drugs and mixed drugs.
The operation is simple, one person can complete it alone, and the whole process of detection only takes 10s.
2. Verification of face and ID card consistency
Built in second-generation ID card reader and face acquisition module, which can verify the consistency of face and ID card at any time .
3.Print test results
Support GPS positioning, and automatically lock the address during detection .
Support the printing of test results. The Bluetooth connected portable printer can print test results anytime and anywhere .
Ⅳ Product Advantages of Iris Toxicology Scan
1.Quick preliminary screening
People of any gender, age and nationality can be accurately detected, and wearing contact lenses does not affect the accuracy of the detection. It can be used for mass detection of a large number of people in public places and entertainment places, and the recognition result of each person can be completed within 15 seconds from the collection.
2. Complementary to the traditional methods
The detector can be used to quickly screen a small number of suspicious persons from a large number of people, and then use the traditional test method for secondary confirmation, which forms complementary advantages with the traditional tests, such as urine test, blood test, saliva test, and hair test.
Advantages compared to urine test, saliva test, and hair test
| Project Method | Iris Drugs Detector | Saliva Test | Urine Test | Hair Test |
| Sample Size | Non | Less Small | More Large | More Large |
| Intrusive sampling or not | Non-intrusive | Non-intrusive ( Hard to adapt physically) | Non-intrusive (Privacy Violation) | Non-intrusive |
| Whether the sample is infectious | No | Yes | Yes | No |
| Sampling efficiency | Very fast and easy | Fast and easy | Slow, labor consuming and easily mixed with, or replaced by fake samples | Very slow, professional sampling required |
| Detection time(Including sampling time) | 10s(Sampling 5s) | mins | mins | mins |
| Whether there is cross-reactivity of the detected substances | No | Yes | Yes | No |
| Whether chronic drug use can be detected | Both ongoing and chronic drug use can be detected | Only ongoing drug use can be detected | Only ongoing drug use can be detected | Both ongoing and chronic drug use can be detected |
| Whether it can be used for on-site screening | Yes | Yes | No | No |
| Whether there are secondary discards causing pollution | No | Yes | Yes | Yes |
| Sample preservation | Easy | Hard | Hard | Hard |
3.Strong identity authentication
At the same time of rapid screening, the detector can obtain the information of face, iris and ID card to carry out online verification of face and certificate consistency through multiple public security systems, and identify the identity information of personnel accurately in multiple dimensions to avoid illegal and criminal acts such as one person with multiple certificates and one certificate with multiple certificates.
4. Deep learning
The detection and screening system is integrated with the latest in-depth learning technology, embedded with an efficient in-depth neural network framework to continuously improve the identification accuracy. The data is synchronized for training and verification, and the algorithm is optimized based on the data training results.
5. Safety and environmental protection
The use of pupil detection avoids contact with the saliva and urine of the tested person. The testers do not have to worry about infection from COVID-19, AIDS or STDs, and no contaminants are produced during the detection process.
6. Prospective
The detection and screening system is relatively independent from other public security systems. It can provide standard interfaces for other public security systems to meet the flexible access of various business systems.
