Course Introduction：According to news on July 31, blogger Digital Chat Station hinted that the Redmi K80 Pro will be equipped with an ultrasonic screen fingerprint, in line with its big brother Xiaomi 15 series, while the standard version of the Redmi K80 will have an optical fingerprint. In principle, the implementation of ultrasonic fingerprints is almost the same as that of mainstream optical fingerprints, both of which use reflection imaging of screen light to identify people's fingerprint information. 1. Ultrasonic fingerprint recognition When the user's hand presses the screen, the reflected light returns to the sensor below the screen through the pixel gap. Because fingerprints themselves are uneven, the reflected light is also different. Then, the algorithm is used to compare the previously input fingerprint images to achieve accurate identification. 2. Advantages of ultrasonic fingerprint Ultrasonic fingerprint can further utilize the unique pulse reflection characteristics of ultrasonic waves to achieve

Course Introduction：Today I will talk to you about the basic concepts related to voiceprint. I hope it will be helpful to you! 1. The concept of voiceprint. In real life, fingerprint recognition may be more common. Common usage scenarios include mobile phone fingerprint recognition, smart door fingerprint recognition, etc. So what is voiceprint? In fact, voiceprints can be used similarly to fingerprints to distinguish features that are different from other people. Simply put, it is the characteristics that distinguish one person's voice from others. 2. Introduction to voiceprint recognition Voiceprint recognition is a type of biometric technology and a category of speech recognition technology. Voiceprint recognition mainly includes two processes: voiceprint registration and voiceprint identification. To put it simply, voiceprint recognition is to convert human voice signals into electrical signals, then perform feature extraction, modeling, and finally matching.

Course Introduction：According to news on February 27, Meizu officials have announced that a Meizu special event will be held at 19:00 on February 29. Judging from the recent official warm-up, the Meizu 21PRO flagship phone is likely to be released at this event. Today, the official revealed another piece of news: Meizu 21 PRO will be equipped with mTouchMax wide-area ultrasonic fingerprint unlocking. Wide-area and ultrasonic are both recognized by the industry as the strongest solutions for fingerprint unlocking. On the one hand, wide-area can make the identification area larger, make unlocking more convenient, and even enable blind operation to a certain extent. On the other hand, ultrasonic fingerprint recognition is faster than ultra-thin, short-focus and other fingerprint solutions, and ultrasonic waves do not require the screen to be turned on to the highest brightness when identifying fingerprints. The pulses emitted by the ultrasonic sensor can sense the unique holes and ridges of fingerprints.

Course Introduction：Face generation technology is one of the rapidly developing technologies in recent years. It uses artificial intelligence and deep learning algorithms to generate realistic virtual faces. However, face generation technology also raises some privacy and security issues, one of which is the protection of voiceprint features. Voiceprint features refer to a biometric feature that identifies and verifies a person's identity by analyzing their voice signals. In face generation technology, the protection of voiceprint features is very important, because voiceprint features can be used in voiceprint recognition systems for identity authentication and other purposes. However, face generation technology is
