comparing values of light intensity of the scatter pattern with values of light intensity of the preauthorized pattern.

3. The method of claim 2 wherein comparing values of light intensity for the scatter pattern with values of light intensity the preauthorized pattern further comprises:

comparing average values of light intensity for each of a plurality of regions of the scatter pattern with average values of light intensity for each of a plurality of regions of the preauthorized pattern, the plurality of regions of the scatter pattern corresponding in location to the plurality of regions of the preauthorized pattern.

4. The method of claim 2 wherein comparing values of light intensity for the scatter pattern with values of light intensity for the preauthorized pattern further comprises:

comparing wavelengths of light for the scatter pattern with wavelengths of light for the preauthorized pattern.

5. The method of claim 1 wherein the light source comprises a laser light source.

6. The method of claim 1 wherein the light source comprises a visible-spectrum light source.

7. The method of claim 1 further comprising specifying by a manufacturer of the lock, the unique preauthorized scatter pattern including:

transmitting toward the lock, at the behest of the manufacturer, light by the light source in the key through the shattered glass forming the prism thereby generating a source scatter pattern;

identifying, by the scatter pattern detecting module of the lock, the source scatter pattern; and

storing the source scatter pattern as the preauthorized scatter pattern in non-volatile computer memory of the scatter pattern detecting module.

8. A lock for lock and key security, the key comprising a light source and shattered glass forming a prism, the lock comprising:

a locking mechanism;

a light receptacle configured to receive light transmitted by the light source in the key through the shattered glass forming the prism, wherein the transmission of the light through the shattered glass forms a unique scatter pattern in dependence upon physical characteristics of the shattered glass;

a scatter pattern detecting module operatively coupled for data communications to the light receptacle and the locking mechanism, the scatter pattern detecting module configured to:

identify the scatter pattern of the received light transmitted by the light source in the key through the shattered glass forming the prism;

compare the scatter pattern to a unique preauthorized pattern for operating the lock;

if the scatter pattern matches the unique preauthorized pattern, switch the current locking state of the locking mechanism; and

if the scatter pattern does not match the unique preauthorized pattern, maintain the current locking state of the locking mechanism.

9. The lock of claim 8 wherein the light receptacle further comprises a charge-coupled device (‘CCD’).

10. The lock of claim 8 wherein the light receptacle further comprises a complementary metal-oxide-semiconductor (‘CMOS’) active-pixel sensor.

11. A key for lock and key security, the lock comprising a light receptacle, a locking mechanism, and a scatter pattern detecting module, the key comprising:

shattered glass forming a prism; and

a light source, the light source configured to transmit light through the shattered glass forming the prism into the light receptacle of the lock in order to switch the locking state of the locking mechanism, wherein the transmission of wherein the transmission of the light through the shattered glass forms a unique scatter pattern in dependence upon physical characteristics of the shattered glass.

12. The key of claim 11 wherein the light source comprises a laser light source.

13. The key of claim 11 wherein the light source comprises a visible-spectrum light source.

14. An apparatus for lock and key security, the lock comprising a light receptacle, a scatter pattern detecting module, and a locking mechanism, the key comprising a light source and shattered glass forming a prism, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of:

receiving, in the light receptacle of the lock, light transmitted by the light source in the key through the shattered glass forming the prism, wherein the transmission of the light through the shattered glass forms a unique scatter pattern in dependence upon physical characteristics of the shattered glass;

identifying, by the scatter pattern detecting module, the scatter pattern of the received light;

comparing, by the scatter pattern detecting module, the scatter pattern to a unique preauthorized pattern for operating the lock;

if the scatter pattern matches the unique preauthorized pattern, switching, by the scatter pattern detecting module, the current locking state of the locking mechanism; and

if the scatter pattern does not match the unique preauthorized pattern, maintaining the current locking state of the locking mechanism.

15. The apparatus of claim 14 wherein the light source comprises a laser light source.

16. The apparatus of claim 14 wherein the light source comprises a visible-spectrum light source.

17. A method of lock and key security, the lock comprising a light receptacle, a scatter pattern detecting module, and a locking mechanism, the key comprising a light source and shattered glass forming a prism, the method comprising:

receiving, in the light receptacle of the lock, light transmitted by the light source in the key through the shattered glass forming the prism, wherein the transmission of the light through the shattered glass forms a unique scatter pattern in dependence upon physical characteristics of the shattered glass;

comparing, by the scatter pattern detecting module, a scatter pattern to a unique preauthorized pattern for operating the lock;
