Payment card authentication system and method

A system and method for authenticating payments are described. In a registration and activation step, an issuer issues to a user one or more patterns of digit substitution associated with a permanent account number. The patterns of digit substitution can then be used to generate derivative account numbers based on the permanent account number. During a commerce transaction, the user interacts with a merchant and specifies a derivative account number. The merchant transmits the derivative account number and other transaction information to the issuer for approval. Based on the derivative account number, the issuer retrieves the permanent account number and processes an approval. By using this method, a user's actual permanent account number is not revealed or transmitted via an unsecure network, which protects it from being stolen. The method may be used in various transactions to protect other personal identification information such as social security numbers, driver license numbers, etc.

Vehicle license plate imaging and reading system for day and night

ActiveUS7016518B2Avoid sensor overload headlightAvoid reflected glareOptical rangefindersRoad vehicles traffic controlLicense numberInfrared
This invention provides an infrared illuminator and camera system for imaging of auto vehicle license plates. The system works in ambient light conditions, ranging from bright sunlight, to dim light, to dark, to zero ambient light. It yields high-contrast imaging of the letters and numbers on retro-reflective license plates. The images of the license letter and number combinations can be read manually by a remote operator. They can be converted to text format with optical character recognition computer hardware and software. The text data can then be compared to data files listing license numbers to provide further data about the owner of a licensed vehicle. A decision can be made quickly about whether to allow a vehicle to proceed through a gate, or whether to take other action. The system uses a mono camera that is enhanced for infrared sensitivity and combined with a high power infrared illuminator to maximize range at night, and with shutter speeds set up to capture clear license plate pictures even with fast moving vehicles and even with their headlights on and interfering with human observation of the license plates. Optical filtering to pass infrared in the range of the illuminator and to reduce light outside this range, combines with a lens set up, to avoid vertical smear and sensor overload caused by headlights at night and by highlight reflected glare from the sun in daytime.
