Biometric identification technology is mainly applied to access control system, attendance management and personnel search in the current campus informatization, which promotes personnel management and security management of the campus.
Now let us have a look
Why do schools need to use biometrics?
Acceptability Analysis Acceptability refers to the degree of people's acceptance of biometric school identification, which is an important prerequisite for technology promotion and application. Fingerprint recognition, face recognition and vein recognition have been commercially used on a large scale worldwide. Most people can accept and use fingerprint recognition for commuting and access management, and some key departments have already deployed and enabled face recognition equipment to strengthen security management. Campus personnel are mainly staff and students, who have a high degree of recognition and acceptance of new things. The successful cases recognized by the society will also help the promotion and application of this technology in the construction of smart campus.
1. Performance up to standard analysis
Performance up to standard means that the recognition should be rapid and accurate, and the supporting resources should be sound. Especially in the application of access management, under the premise of accuracy, the recognition range should be large enough and the degree should be deep enough to avoid causing queuing congestion. With the development of information technology, the biometric identification system has been able to accurately identify, extract, judge and process the biometric information.
Security analysis security means that it is not easy to be copied, recognition is stable, and the system cannot be cheated by using fraudulent methods. Any system itself has certain security risks, and biometric system is no exception, but its technical maturity makes the risks manageable. The authoritative database LFW shows that the accuracy rates of fingerprint, face and iris recognition reach 98%, 99.8% and 99% respectively. Biometric technology has already been applied to the social payment industry, and it is constantly being updated to improve accuracy and reliability. For the campus education management and non-large amount consumption management environment, there will be no "physical cloning", and it is fully capable of meeting the current needs of campus wisdom application, and the security risk is extremely low.
2. Application in current campus informatization
Biometric school identification system technology is mainly applied to access control system, attendance management and personnel search in the current campus informatization, which promotes personnel management and security management of the campus.
Access control system mainly applies biometric identification technology to access management. Some college buildings are still using swipe cards for access management, but some faculties have adopted fingerprint unlocking for access to buildings or offices, and a few units have adopted face recognition for security access management of important places.
Attendance management is mainly the application of biometric identification technology in the management of commuting. At present, most schools have installed fingerprint sign-in machines or iris recognition terminals to replace the previous card-swiping mode in order to strengthen the order management of staff commuting to and from work and grasp the school information, which effectively avoids the appearance of the previous card-swiping situation.
Personnel search is mainly the application of biometric technology to locate personnel. In some cases, according to the photos and portraits of people, we can search and compare people through face recognition, especially when the school security department finds suspicious people in campus activities, we can quickly find and locate their locations.
3. Application expansion in the future construction of smart campus
People's bodies contain a large amount of rich biometric information, and mining biometric information through big data and biometric technology can promote the organic combination of body informatization and university campus informatization, gradually forming a new situation of intelligent management. In the construction of smart campus, it should be implemented on the basis of scientific proof combined with specific application needs and future needs, unified planning, and integration of existing biometric systems so that the big biometric system can be fully integrated into the smart campus and provide smart management services.
Candidate identity information verification Candidate identity information verification is the upgrade of biometric identification in access management application, which is the verification of the authenticity of candidates' identity and requires more fine and accurate. In recent years, with the mature development and popularization of biometric technology, some provinces have adopted the dual technology of face recognition + fingerprint recognition to confirm the identity of candidates in the college entrance examination. In the past, because the biometric technology is not yet mature, only through the human eye to test candidates and their pass, ID photo comparison to confirm whether the candidate is real, although usually the recognition of the correct rate is high, but there is inevitably misidentification, misjudgment; and face recognition can greatly reduce the rate of misjudgment, can effectively avoid substitution test.
Integrating artificial intelligence and big data technology to promote teaching activities Integrating biometric identification technology with other intelligent technologies for use, such as biometric identification + artificial intelligence, biometric identification + big data, to expand the management scope, realize refined management and improve service level.
For example, it can be combined with video monitoring system for smart classroom analysis, using classroom smart monitoring system to count both the number of classroom personnel and the time of going to and coming from class, as well as applying face recognition technology for behavioral characteristics judgment, and forming analysis of teachers' and students' attitudes during class by analyzing teachers' and students' expressions in the classroom, combined with big data technology processing, etc.
To carry out activities of personnel, crowd control, for some lecture reports or courses due to the content of the main lecture or space constraints of the venue and other circumstances, the number of students and professional need to limit, can be preset access to personnel information, face recognition access control to enter the personnel, with the help of video surveillance system face recognition function, not in the authorized range of personnel to enter the alarm prompt, personnel avatar synchronous display in the console and large screen, or in the personnel When the crowd is concentrated, it will prompt the personnel to intervene to ease the situation.
The perfect integration of multiple biometric technologies and intelligent technologies will surely expand the application scope and enhance the security application to a new level.
Providing health information service for school personnel The campus has a high density of personnel and each year involves thousands or even tens of thousands of people for medical checkups, which requires a lot of manpower and material resources to arrange according to the medical checkups. After applying biometric identification system, data of some basic physical examination items will be extracted directly from the system, and these items will be included in the exemption check during the unified physical examination, such as age, height, body type, blood pressure, etc. Individual biometric identification system also has the function of judging whether an individual is sick or not, such as fingerprint identification can identify certain chromosomal abnormal diseases, and iris identification can identify whether an individual is suffering from AIDS.
In addition, the face recognition system can determine the individual's mood and personality, so as to provide the basis for the psychological state and do prevention. In the future, as technology continues to advance, it will also be possible to conduct physical examination and monitoring by means of waves. The information about individual health or disease mined from biometric information needs to be valued and scientifically utilized to reduce the negative consequences generated by biometric body informatization.
In addition, biometric identification can also be combined with video system to realize unmanned restaurant, where meal selection and meal dispensing are done automatically by self-service equipment, and people only need to stand at the window to identify and pay for the meal. This service has already been put on trial in some first-tier city restaurants.
4 Issues to note when applying
To fully consider the influencing factors Application demand, applicable population and scale decide the technology selection, to ensure the need of application, but also to compress the construction cost, choose the system which is easy to upgrade management and maintenance. The environment of biometric identification system may have an impact on the recognition result. For example, fingerprint recognition, because of the touch verification method, has high requirements on the environment where it is located, finger humidity and cleanliness, and it is impossible to recognize people with worn fingerprints, born without fingerprints or with few fingerprint characteristics. Iris recognition and vein recognition are widely considered to have the same accuracy as DNA matching, but their hardware cost is high compared to other biometric hardware, making it difficult to promote them on a large scale.
The process of face recognition may be affected by various factors such as lighting conditions and facial masking. To sum up, the appropriate recognition technology or technology combination should be selected in the specific construction, taking into account the application requirements, physical environment, crowd characteristics, security level, construction cost, etc.
Pay high attention to privacy protection Biometric identification involves fingerprints, iris and other biometric features, some of which have been used as important features for identity verification in public security, banks and other departments. Once the biometric features are successfully extracted, they will be transformed into data, and the biometric features are basically unchanged for a lifetime, so if the data is leaked, it will cause very great impact, such as the authoritative verification channel for universal biometric payment in India has had a privacy leak.
The Network Security Law has included personal biometric information into the scope of personal information, but has not yet clearly refined the relevant management requirements for the highly private specificity of biometric information. Therefore, it is also necessary to focus on the security protection of personnel information, especially biometric information, in the smart campus. It is recommended to retain only the irreversible biometric data or models after algorithm processing, and not to retain the original data images, audio, video and other data information; and to encrypt the biometric database to prevent information leakage and unnecessary losses to personnel.
Biometric data can be used for enhanced learning in seven several ways
1. More efficient use of time
Biometric data can streamline many administrative processes that would normally take up a lot of classroom time. For example, attendance can be automatically inferred from a fingerprint scanner at the door or a camera in the classroom. This can save 3 to 5 minutes per class, or approximately 10 hours of instructional time over the course of an academic year.
This technology not only assesses when students are absent, but also records exactly how much time they have missed. Using this information, teachers will know exactly what missed course material needs to be taught or condensed for each individual. Online learners can also use the same principles to keep up - all they need to do is communicate with the instructor. This will ensure equality among students and richer classroom discussions/collaboration.
2. Keeping students safe
One of the most obvious applications of biometrics in schools is the use of scanners for security purposes. Verifying an individual's fingerprint or iris to authenticate their identity is an effective way to keep students and staff safe from harm. These can also prove helpful in other areas that students need to visit throughout the school day, such as the cafeteria.
When suspicious people try to enter the school, scanners can prevent them from doing so. In the worst case scenario, surveillance cameras can identify when unauthorized persons are entering the premises and automatically enable lockdown protocols.
Radio frequency identification (RFID) chips can also be used to track the location of students. With RFID technology, it is easier to ensure that learners, especially younger students, arrive at school and return home safely. 3.
3. Better understanding of student engagement
Biosensors, including infrared and surveillance cameras, can be used to infer student engagement and identify behavioral issues. Observing their behavior - such as eye contact, interactions with other students, and body language - can convey a lot about how learners interpret classroom material. Using big data, these recordings can help teachers when learners may lose interest, need help, or have any distractions in the room.
This information can help teachers personalize lessons to meet the needs of each student. It can let teachers know which strategies are most likely to stimulate engagement, and it can be a particularly useful way to evaluate the effectiveness of new educational technologies, although there are ethical considerations for big data collection in schools.
4. Ensuring Academic Integrity
Accurate assessment results are an important part of education; it allows school districts and teachers to assess each individual's progress and their competence as educators. When the integrity of our assessment tools is threatened, it poses a serious threat to the achievement of educational goals.
Technology is the double-edged sword of education. A wide variety of hardware and software is needed to meet the educational needs of the modern student. Unfortunately, cybersecurity vulnerabilities can allow hackers (and sometimes students themselves) to alter grades or access unauthorized resources during assessments. This is especially true for online learners, as the absence of a teacher can open the door to ethically dubious behavior.
Biometric scanners can reduce the severity of this problem by verifying the identity of users and preventing them from accessing unauthorized records or cheating during assessments. They are often used in exam centers, although many online courses require students to have webcams to monitor them during the assessment process - a process known as "webcam proctoring.
With the promotion and application of intelligent biometric technology in finance, transportation, business and other fields and its continuous upgrading, people have generally accepted fingerprint recognition, iris recognition, face recognition, voice recognition, vein recognition, signature recognition, etc. Among them, fingerprint, iris, face and vein are the four features with the most successful application and highest market share, and have become important means for some departments to improve management efficiency. With the deepening of smart campus construction, intelligent biometric technology will be widely used and play an important role in smart management.
5. Securely registering attendance with school's biometric system
First, a school biometric system can be a really effective way to register student attendance. It's unlikely you'll be able to use the solution for attendance in primary schools, but in secondary schools, colleges and universities, biometrics can prove invaluable.
Whether schools use them just to register attendance at the beginning of the day or for individual classes, biometrics are a very easy authenticator for students to use. All they have to do is scan their fingerprints on the sensor as they enter the classroom.
It's a form of identification they can't lose or forget. Unlike passwords or smart cards, students also can't share it with friends. Overall, this makes it a powerful and secure and fast method of registering attendance.
It can also be a great way to monitor sixth graders or college students as their schedules become more flexible. If they use biometrics to log in and out of school, the school can always know in real time who is present and who is not - essential in case of emergency.
6. Increase the inclusiveness of school dining biometric systems
Checking in attendance is the most obvious benefit of a school biometric attendance system software system, but at FasTrak, one of our favorite benefits is the difference it can make to a catering solution. When catering is cashless and payment is made via biometric scanning instead, you can bring a number of advantages to school catering.
First of all, it makes catering fun, engaging and fast for students, which increases the number of users. This is great for all involved: students get the food they need to focus in class, and the school provides a more profitable and efficient food service.
Perhaps more importantly, biometric and cashless dining can help increase inclusivity and access to school meals for the students who need them most nutritionally. Unfortunately, many students who are entitled to free school meals do not actually use the benefit. The social stigma of receiving free school meals causes many students and parents to avoid claiming it because it singles out children as "poor" during meal times. Kids don't want to be the only ones not paying when all their friends are handing over cash.
This is where cashless biometric systems come in handy. When there is no cash, the payment is hidden in the background. Whether your parents or the state paid for the meal, it's impossible to know when biometric ID verification is involved. Eliminating this stigma means a lot to schools and parents, and can help students who really need free school meals actually get it.
7. Library management systems
Have you forgotten to bring your student ID card or ID card that doesn't prove you are a student at this school, with biometrics none of these are needed, just enter your school number, enter your fingerprints or verify your facial information and your information will be available in the system.
