| 1. A method of biometrics identification including:
obtaining an image of an area of a portion of an inner surface from an individual,
identifying at least two points representing the areas between fingers of the hand determining a coordinate system for the
image, the coordinate system having a first and a second axis, wherein the two points are located on the first axis and are
equidistant from the second axis;
identifying a sub-image of the image, the sub-image including skin surface within an area defined by points (0.25D, 0.5D),
(1.25D, 0.5D), (0.25D, −0.5D) and (1.25D, −0.5D) in the coordinate system, where D is the distance between the two points,
analyzing the image to extract texture features of the skin surface, and storing the texture data as a vector, wherein analyzing
the image includes applying a threshold to the sub-image to identify palm print pixels in the image and analyzing the palm
print pixels using a Gabor analysis, and
comparing the texture features with reference information in a database based on a hamming distance.
