Our sources indicate that the Ministry of Sardonic Smiles has developed a new, ultra-secure smile-based encryption method.
This method, dubbed "The Sardonic Smiler," utilizes AI-powered facial recognition software to detect and decode smiles.
To infiltrate this system, you will need to acquire a pair of custom-made, ultra-high-resolution smile-printed glasses.
Further instructions and high-resolution smile-print images are available on the secure wiki.
