Method of generating unique quasi-random numbers as a function of time and space

Disclosed is a method of generating unique, quasi-random numbers as a function of time and space. Benefits include improved ease of number generation and the utilization of existing hardware.

Description

              Many applications require either a random number or a unique number or both to facilitate the encryption and unique identification of a transaction or other entity. The disclosed method generates unique quasi-random numbers if GPS functionality is available. A time value from a GPS device is concatenated with the location value from the device. If additional quasi-randomness is required, some simple function of the two values can be performed, such as XOR or multiplication. The function masks the actual values from which the result is derived. When two closely co-located devices are used to generate undisguised values, the resulting values are unique even if generated at exactly the same time because the location values are unique.  

              The resulting values could serve as random numbers in a key negotiation. For example, the quasi-random numbers could serve as an ID for a transaction between a GPS-equipped cell phone and an e-commerce site. The ID would contain information about both the time and location from which the transaction was originated. Many other possibilities exist for the use of quasi-random values.

Advantages

              Truly random numbers are notoriously difficult to generate. The disclosed met...
