Seeing Through the Facade

In an era where data breaches have become more prevalent than ever, the importance of data encryption technologies cannot be overstated. From protecting personal information to safeguarding corporate secrets, encryption has become a critical tool for ensuring the privacy and security of sensitive data.

One example of the importance of data encryption can be seen in the healthcare industry. With electronic health records becoming the norm, patient data has become an attractive target for cybercriminals. Encryption can help ensure that this data remains protected, even if it falls into the wrong hands.

Similarly, in the financial sector, encryption is used to protect sensitive financial data, such as credit card numbers and banking information. With the rise of online banking and e-commerce, the need for encryption has become even more pressing.

But it's not just large corporations and institutions that need to worry about data security. Individual users also benefit from encryption technologies. For example, end-to-end encryption is used in messaging apps like WhatsApp and Signal to ensure that conversations remain private and secure. And encryption is also used to protect data stored on devices such as smartphones and laptops, making it more difficult for hackers to access personal information.

YouTuber MayLabs recently described an interesting device that can encrypt or decrypt data just by looking at it. The device is built into a pair of glasses and a companion smartwatch that work together to reveal secret information that is hidden in plain sight.

An off-the-shelf pair of sunglasses was given the ability to capture images using a compact HD USB camera module that was fitted into a 3D-printed case that was designed to attach to the frames. This communicated via a wired, USB connection to a Raspberry Pi 4 8 GB single-board computer-powered smartwatch that MayLabs had previously designed. The Raspberry Pi provides the processing power for the design, and the watch also already had a number of functions built in, like the ability to interact with ChatGPT.

Captured images are processed by a neural network that was trained to recognize letters, whether they are printed or handwritten. When the detected writing is encrypted, it will appear to be gibberish, but a decryption algorithm running on the Raspberry Pi can translate it into the actual, unencrypted form. The result is displayed on a small screen on the smartwatch.

If you want to leave an encrypted message, you can press a button on the watch, then speak the word or phrase to encrypt. The algorithm will calculate the proper value and display it on the screen. When that string of characters is in view of the glasses in the future, it will be automatically decrypted and displayed on the screen.

This device may not prove to be the go-to password manager for anyone, but there are some potential interesting use cases for it. Printed documents containing sensitive information, for example, could be encrypted so that they could be read in public without concerns about privacy. This would be especially useful if the device were modified to provide an augmented reality display in which the decrypted text were displayed within the visual field of the wearer, rather than on a wrist-worn display.
