Patent ID: 7809163

Claim:
A method for prohibiting a person with a facial mask to operate an automatic teller machine, comprising the following steps of: a. arranging a visual spectrum image capturing unit and an alarm unit approaching an automatic teller machine (ATM); b. capturing a subject visible spectrum picture of an experimental subject via said visual spectrum image capturing unit; c. judging if said subject picture shows generic features of a human face; if said face features are recognized as false, it then directly goes to Step g.; d. if said face features are recognized as true, a facial temperature of the subject is detected to gain a measured temperature; e. comparing said measured temperature with a predetermined reference temperature; if said measured temperature resulting from the comparison fails to be within a range of said reference temperature, it is determined as a spurious human face and then directly proceeds said Step g.; f. if said measured temperature resulting from the comparison is within the range of said reference temperature, it is determined as a genuine human face and said ATM is allowably operated without proceeding said Step g.; and g. triggering said alarm unit to transmit a warning signal without operating the ATM.
