Google recently announced that they are banning facial recognition on Google Glass until privacy protection is in place. This decision underscores the growing concerns about privacy and the potential misuse of facial recognition technology. However, this doesn’t mean that Google Glass will not get facial recognition capabilities in the future. The tech giant is likely to revisit this feature once robust privacy safeguards are established.
The Privacy Visor: A New Solution
In response to these privacy concerns, a new device called the Privacy Visor has been developed. This innovative gadget could potentially be used to block facial recognition on Google Glass and other similar systems. The Privacy Visor was developed by Japan’s National Institute of Informatics, and it represents a significant advancement in privacy protection technology. Have a look at the video below to see how it works.
The Privacy Visor employs a clever mechanism to thwart facial recognition systems. According to the developers, “You can try wearing sunglasses. But sunglasses alone can’t prevent face detection. Because face detection uses features like the eyes and nose, it’s hard to prevent just by concealing your eyes. This is the privacy visor I have developed, which uses 11 near-infrared LEDs. I’m switching it on now. It prevents face detection, like this.”
How the Privacy Visor Works
The technology behind the Privacy Visor is both simple and effective. “Light from these near-infrared LEDs can’t be seen by the human eye, but when it passes through a camera’s imaging device, it appears bright. The LEDs are installed in these locations because, a feature of face detection is, the eyes and part of the nose appear dark, while another part of the nose appears bright. So, by placing light sources mostly near dark parts of the face, we’ve succeeded in canceling face detection characteristics, making face detection fail.”
This innovative approach leverages the limitations of current facial recognition algorithms, which rely heavily on the contrast between different parts of the face. By disrupting this contrast with near-infrared light, the Privacy Visor effectively renders facial recognition systems unable to identify the wearer.
The implications of this technology are far-reaching. As facial recognition becomes more prevalent in various sectors, from law enforcement to social media, the need for privacy protection tools like the Privacy Visor will only grow. For instance, in public spaces where surveillance cameras are ubiquitous, individuals concerned about their privacy could use the Privacy Visor to maintain anonymity.
Moreover, the Privacy Visor could also be beneficial in professional settings where confidentiality is paramount. Journalists, activists, and other individuals who may be at risk of being targeted could use this technology to protect their identities.
In conclusion, while Google is taking a cautious approach by banning facial recognition on Google Glass until privacy protections are in place, innovations like the Privacy Visor offer promising solutions to these concerns. As technology continues to evolve, it is crucial to balance the benefits of new advancements with the need to protect individual privacy. The Privacy Visor is a step in the right direction, providing a practical tool for those who wish to safeguard their personal information in an increasingly digital world.
