Abstract

An enclosure for a biometric sensor is described. The enclosure comprises a cabinet having a plurality of surfaces. The biometric sensor placed inside the cabinet on a holder fixed on a primary surface from amongst the plurality of the surfaces. A secondary surface from amongst the plurality of surfaces is opposite to the primary surface. The secondary surface is substantially transparent to electromagnetic rays emitted by the biometric sensor.

Claims

1. An enclosure for securing a biometric sensor, the enclosure comprising a cabinet having a plurality of surfaces, wherein the biometric sensor is placed inside the cabinet on a holder fixed on a first surface from amongst the plurality of the surfaces of the cabinet, wherein the holder comprises a placement area for the biometric sensor, wherein a second surface of the cabinet is opposite to the first surface, the second surface is composed of a material transparent to electromagnetic rays emitted by the biometric sensor and coupled to a proximity sensor of the cabinet and configured to activate the biometric sensor upon detection of biometric characteristics, and wherein the biometric sensor emits the electromagnetic rays from a third surface, and wherein the third surface is the top surface of the biometric sensor located at the opposite of the holder.

2. The enclosure as claimed in claim 1, wherein the second surface is at a predefined angle from the third surface, and wherein the predefined angle ranges from 3 degree to 35 degree.

3. The enclosure as claimed in claim 1, wherein the biometric sensor is one of a palm sensor, a finger print sensor, an iris sensor, a footprint sensor, a hand/feet geometry sensor, an ear lobe geometry sensor, and a face biometric sensor.

4. The enclosure as claimed in claim 3, wherein the palm sensor is a palm vein sensor.

5. The enclosure as claimed in claim 1, wherein the cabinet comprises a door with a locking mechanism to place and remove the biometric sensor in the cabinet.

6. The enclosure as claimed in claim 1, wherein each of the plurality of surfaces of the cabinet, other than the second surface are coated to absorb unwanted illuminations around the biometric sensor.

7. The enclosure as claimed in claim 1, wherein material comprising at least one of a clear glass, a clear hardened glass, a etched glass, a etched hardened glass, a partially etched glass, a partially etched hardened glass, a patterned etched glass, a butter paper, a translucent plastic sheet and an acrylic sheet.

8. The enclosure as claimed in claim 1, wherein the second surface is placed in a field of view of the biometric sensor at a predefined distance such that the second surface is within focus of the biometric sensor.

9. The enclosure as claimed in claim 1, wherein the second surface is placed below a hardened glass sheet such that the hardened glass sheet provides support to the second surface thereby protecting the biometric sensor.

10. The enclosure as claimed in claim 1, wherein the second surface includes guide marks to guide a user.

11. The enclosure as claimed in claim 1, wherein a layer substantially transparent to the electromagnetic rays is overlaid on the second surface.

12. A system comprising:

an enclosure comprising a cabinet

the cabinet includes a biometric sensor comprising an electromagnetic ray transmitter for transmitting electromagnetic ray and a camera to capture reflected electromagnetic ray from the biometric source;

a first surface of the cabinet and wherein a holder is fixed on the first surface configured to hold the biometric sensor, wherein the holder comprises a placement area for the biometric sensor;

a second surface of the cabinet located opposite to the first surface, and is the second surface is composed of a material transparent to electromagnetic rays emitted by the biometric sensor a third surface is a surface from where the biometric sensor emits the electromagnetic rays, and wherein the third surface is the top surface of the biometric sensor located opposite to the holder and;

a proximity sensor coupled to the second surface of the cabinet, wherein the proximity sensor is configured to activate the biometric sensor upon detection of a biometric characteristics.

13. The system as claimed in claim 12, wherein the enclosure comprises an opening for connecting wires to the biometric sensor.
