Face recognition makes future development breakthrough security

Because of its early application, low price, and ease of use, fingerprint recognition has occupied most of the domestic market at an early stage. Even at the peak, it can even reach about 90%. However, what kind of power is it that makes face recognition so rapid in just five or six years?

Policy factors: Regardless of technical factors, the support of national policies can be considered as one of the important factors for the rise of face recognition. In particular, with the vigorous promotion of technologies such as safe cities in recent years, the demand for the security market in China has also rapidly increased, and the level of security in various areas has also been significantly improved. Even in some areas of some regions, face recognition has begun to be listed as a mandatory standard in the use process. The emergence of this situation is undoubtedly a very powerful promotion for the promotion of face recognition. Therefore, although the role of policy is only a kind of induced effect, this kind of induction is indispensable for the outbreak of face recognition.

Social needs: In China, as the process of urbanization accelerates, the proportion of floating population has greatly increased, and the unexpected events and abnormal events are becoming more and more complicated. Therefore, this has also brought greater pressure on the city's security work and video surveillance. The traditional way of relying on artificial staring will inevitably affect the monitoring effect due to fatigue or lack of concentration. It is difficult to perform analysis and understanding of huge databases, thus affecting the search for evidence afterwards, and it is even more difficult to meet the needs of the times. Therefore, people The demand for video surveillance applications with intelligent analysis is increasing.

Algorithm innovation to solve the price dilemma In all biometric technologies, the most easily integrated with traditional video surveillance technology is the face recognition technology. The face recognition module is installed in the camera, and then the face detection technology is used in the control system. Analyze the face extracted from the video stream. After face recognition is “grafted” to video surveillance, even in a more complex scene, the identity of a specific person can be identified at a relatively long distance, which is in line with the needs of modern monitoring.

In addition, the development of intelligent video analysis technology has also promoted the development of face recognition to some extent. In the work, it mainly analyzes the shape, color, motion metrics, etc. of the objects in the image. After the intelligent video analysis, the face recognition can identify the identity features more accurately and improve the market of face recognition products. The scope of application.

For many biometric technologies, the recognition rate is often one of the major factors that plague the performance of the device. But in more time, the biggest technical dilemma of face recognition has not appeared in the recognition rate, but the cost of the core technology of the device.

Before 2009, although high-end products above RMB 10,000 were no longer common, products with prices of RMB 5,000 to 6,000 were not uncommon. Price seems to be the last threshold to affect face recognition applications. However, during the period around the year 2009, the technical algorithms for infrared face recognition and 3D face recognition achieved very large improvements. It quickly freed up the cost of core technology, and that is, at this moment, the non-technical restrictions that prevent face recognition are almost completely broken, and face recognition has also ushered in the sprint of the market.

The trend of face recognition is combined with video surveillance: With the further development of face recognition technology, face recognition technology will be further integrated with the digital surveillance system, and will become another application area of ​​face recognition technology. According to statistics, in mainland China alone, it is expected to generate annual sales of more than 10 billion in the next three years, and in the next 10 years, it is expected to have a market size of over 100 billion in annual sales.

Gradually replacing fingerprint attendance: Face recognition attendance, through the face of some unique features to identify and verify attendance, the current level of technology has broken the influence of the luminous, can achieve rapid recognition in the natural state. At present, face recognition attendance products are still in a state of starting development in the market, but the advantages of face recognition attendance technology have not been exceeded by other similar products.

Face recognition attendance completely eliminates the occurrence of time punch attendance, eliminates the use of finger print attendance, and is non-contact, intuitive, friendly, and widely applicable. Nowadays, as technology continues to mature and costs decrease, face attendance gradually reveals the trend of replacing fingerprint attendance.

Breakthrough in application areas: In the biometric recognition market, the application of face recognition has gradually exceeded the security field. For example: the use of face recognition for mobile phone unlocking and computer landing authentication; some advertising companies use face recognition technology for outdoor advertising for traffic statistics; social security systems have activated face recognition technology, standardize the qualifications of recipients, the airport uses human face Identification technology for security checks and more.

Difficulties still exist: take-off is easy to dominate difficult Although face recognition in the market share, ushered in the long-awaited outbreak, but this does not mean that all factors that hinder the development of face recognition have disappeared. Some of the recognized flaws in technology still pose a number of hidden dangers to the application of face recognition.

First of all, technically speaking, the longevity of the recognition template is still a problem of face recognition. Although facial images are indeed the most intuitive and easiest-to-estimate biometrics, they are also the areas of the human body most susceptible to large-scale changes. Due to changes in lighting, posture, and age, it is not always easy to make templates work with these changes.

In addition, face recognition is a relatively new technique in the entire biometric identification, but this new trend is not only an advantage. It is undeniable that the rapid spread of face recognition, there is some people's psychology of "preliminaries" - people are curious about the new technology, eager to try. However, because of the "newness", its accuracy rate has not yet been sufficiently proved, so users are often prone to mistrust, and thus lose their freshness when faced with face recognition with uncertainties. After that, I am afraid that many users will prefer to choose biometrics that are already well-known.

Therefore, although face recognition has achieved brilliant achievements in the market, "salted fish" has achieved its own take-off. However, if you want to completely realize the acquisition of fingerprint products in half of the country and realize the absolute mainstream of applications, I am afraid that there are still many roads that need to be pursued.
