An anonymous reader writes "A young male of Asian appearance was caught in disguise during a flight from Hong Kong to Canada. The disguise consisted of a molded silicone face and neck mask, hat, glasses and cardigan. An intelligence alert (PDF) from Canada Border Services Agency contains photos of the man with and without the disguise as well as further details of the incident. Suspicions were raised at the start of the flight when the subject was noted as having an elderly appearance that didn't match his hands of youthful appearance. Later in the flight the subject entered an aircraft washroom to remove the disguise and was caught emerging as an early 20s Asian male. This disguise is more elaborate than those used by the suspected perpetrators of the assassination of Mahmoud Al-Mabhouh in Dubai, January 2010. Will the continued introduction of biometric passport security deprecate the use of disguises or will disguises simply become more sophisticated?"
