Abstract

A means in a security system to identify a genuine human face includes: a) generating a subject picture to be tested; b) determining if the subject picture gives features of a human face; e) if yes, the temperature in the subject picture being detected; and f) comparing the detected temperature with a reference temperature, and determining that the subject picture is a genuine human face if the difference resulted from the comparison falls within a pre-set range of error.

Claims

1. A means in a security system to identify a genuine human face comprising:

a) generating a subject picture to be tested;

b) determining if the subject picture gives features of a human face;

c) if yes, the temperature in the subject picture being detected; and

d) comparing the detected temperature with a reference temperature, and determining that the subject picture is a genuine human face if the difference resulted from the comparison falls within a pre-set range of error.

2. The means in a security system to identify a genuine human face of claim 1, wherein Step a) is performed in the following sequence:

a1) retrieving a first picture;

a2) retrieving a second picture after a given lapse of time; and

a3) if the second picture is different from the first picture, the second picture being applied as the subject picture to be tested.

3. The means in a security system to identify a genuine human face of claim 1, wherein Step c) is a detection of the temperature of the human face blocks.

4. The means in a security system to identify a genuine human face of claim 1, wherein Step e) is to sound an alarm signal once it is determined that the subject picture is not a genuine human face.

5. The means in a security system to identify a genuine human face of claim 1, wherein Step a) is to sense a subject to generate a subject picture;

the subject picture being given an oval comparison to generate human face blocks; and

Step b) determining whether the human face blocks in the subject picture give the features of a genuine human face.
