Audible barcodes – a symphony of data

Written by

AuraCodes enable the encoding and decoding of digital information through the medium of sound.

Barcodes and QR codes have become ubiquitous sights in our current information age. However, they have some notable limitations – specifically, the requirement for line of sight, close physical proximity of the reader to the code, and adequate lighting for accurate interpretation. Soorya Annadurai, an independent researcher and software engineer at Microsoft in the USA, has developed a solution for […]

Anamorphic cryptography: How can we ensure private communication?

Written by

Professor Moti Yung conceptualised anamorphic cryptography, a form of encryption that is secure even when keys are known to the adversary.

Cryptosystems have been developed to send secure messages with the assumption that the receiver’s key – what the intended recipient needs to read the message – is secure from adversaries. However, there have been tensions, dubbed as ‘Crypto Wars’. Friction has arisen between governments, hoping to access encryption keys to learn about potential threats, and industry, which believes that the […]
