Electronic enthusiasts eight o'clock: According to foreign media reports, in the classic animation film "The Incredibles" produced by Pixar in 2004, there is an unforgettable episode: "Mr. Super Energy" in the film picks up A very thin tablet that uses face recognition to verify his identity before telling him what to do to perform a secret mission.
In the past 13 years, many thin and light mobile phones and tablets now support the way to unlock devices by pressing finger prints, and the face recognition technology in Superman mobilization seems to be coming to us. For example, some laptops and mobile devices are now supporting face recognition technology. In addition, as the dedicated hardware that is small enough to fit into our mobile phones continues to mature, the future application of this technology is likely to usher in a huge expansion.
So we have every reason to believe that using the face to unlock the device will soon become commonplace, no longer the privilege of spies and superheroes.
Technology firstAs a leader in the mobile device chip industry, Qualcomm recently introduced the "Spectra imaging system", which extracts depth information from objects including faces. The company's plan is to embed the technology into the upcoming Snapdragon flagship mobile processor. At the same time, after Apple's upcoming HomePod smart speaker firmware leaked on the Internet, developers found some important clues that the new iPhone might also be configured with depth perception and face recognition.
It should be pointed out that this technology is different from the face recognition technology widely used in surveillance cameras around the world. The latter mainly obtains information by comparing the database with the face photos with millions of face photos, and It has been increasingly used in security surveillance, payment and other fields.
Fortunately, the mobile phone camera in the hands of users now has some advantages over the monitoring device. The mobile camera does not need to identify you in the crowd, it only needs to identify the user's face. What's more, the phone camera is perfectly suited for this task, and it can quickly take fine photos even one or two feet away from you.
Another advantage of this technology is that depth sensing technology called "structured light" virtually squirts thousands of tiny infrared dots on a person's face or any other target object. By identifying the distortion in this infrared spot, the camera collects very accurate depth information. And because the phone's camera can see infrared light, and people can't see it, this type of system allows the phone to be unlocked in a completely dark environment.
Although Apple has not officially announced that it will use such technology, the company is no stranger to infrared depth modeling and face recognition technology. The company has previously been awarded a very similar process patent, but Apple has always refused to comment on the technology it may be developing.
Simply put, Apple's process patents are similar to the streamlined version of the Microsoft Xbox 360 Kinect motion sensor. Moreover, Apple acquired the early developer of Kinect and the Israeli startup PrimeSense as early as 2013, so the deal may not be an accident.
At the same time, Qualcomm plans to push the Spectra processor to future Android phones. Samsung's previous image processor that supports face recognition sometimes mistakes the face photo placed in front of the phone's camera as a real person. But Qualcomm insists that the depth-sensing face recognition technology will use "activity detection", so even 3D printed masks can't survive the system (but the company also acknowledges that identical twins may be able to pass the system test) .
Broad prospectsSy Choudhury, Qualcomm's senior director of safety and machine intelligence products, points out that teaching our phones to know what our faces look like is just like teaching them what our fingerprints look like. Because the phone will take a photo of your face first, and then extract relevant feature information. When you unlock your phone, it will compare this information with your face to determine if you can unlock the device.
As with fingerprint recognition, user face information is safely stored on the device, not the cloud. Since Apple refused to unlock the suspected iPhone and interacted with the FBI, Amazon insisted that its voice assistant Alexa would not upload any voice information in the inactive state, the technology companies may use this privacy protection in the future. One of the important selling points of equipment and technology.
At present, some laptops have used Microsoft Windows Hello face recognition technology to achieve fast landing, and some devices are already equipped with Intel's RealSense 3D depth camera.
In this regard, biometrics founder and co-CEO Joey PriTIkin said that such technology will gradually deepen the mobile supply chain, achieve price down, and then enter the lower-priced low-end equipment. .
We have every reason to believe that future face recognition technology will appear on smart doorbells equipped with cameras, smart door locks and smart speakers such as the Amazon Echo Show. On these smart devices, providing personalized services to users will bring extra points, such as if the system knows that you are using it, it may automatically play the latest episode of Game of Thrones. If it recognizes that your child is using it, it may automatically play the "SesameStreet" program.
Short board still existsLike all new technologies, face recognition can cause problems while bringing security and convenience. Scanning fingerprints may be more convenient in many usage scenarios. Because the face recognition algorithm may not work properly because the user is wearing or not wearing glasses, especially sunglasses. You may need to take off your gloves when using fingerprint recognition to unlock your phone in the winter. However, when using face recognition, you may need to re-enter your facial features each time you change your hairstyle.
Moreover, it seems that all biometrics have their own shortcomings, such as iris recognition technology may be more special than face recognition. Because the use of this technology requires the phone to get to the user's eyes, and because the iris lacks contours, the technology will be confused by static iris images.
Unlimited potential“What's interesting about face recognition is that it can become ubiquitous because camera sensors are easy to deploy. I think it's only a matter of time before we use multiple biometrics in our daily activities.†Pritti Jin added.
Considering that Apple's existing fingerprint sensor already supports Apple Pay's verification of payment at the merchant, we believe that Apple will support verification of payment through face recognition technology in the future.
Of course, the most notable aspect of this face recognition technology is that it has enough potential to penetrate people's daily lives. For example, in the future, users only need to look at the camera of the device to get some kind of permission, and people can easily see this as a normal thing.
To be sure, face recognition technology can provide users with a higher level of security and help us get rid of the bad habits that put our bank accounts and online life at risk. Of course, this is not to say that these systems will not be compromised. But at least in the short term, it’s much safer to smile at the phone every morning than to enter the same password to unlock the device repeatedly.
