Abstract
A fingerprint sensing integrated circuit device includes a fingerprint sensing device, an encryption unit, a multiplexer and a transmission interface. The encryption unit is connected to the fingerprint sensing device. The multiplexer has an output end, a first input end and a second input end. The first input end of the multiplexer is connected to the fingerprint sensing device. The second input end of the multiplexer is connected to the encryption unit. The multiplexer connects the output end to the second end according to a selection signal. The transmission interface is connected to the output end of the multiplexer.
