Abstract:
A method for configuring a computerized system at a remote location, comprising the steps of:storing a validation identifier inside said system; transmitting an option identifier which identifies a change in system configuration from said remote location to a central location; encrypting said validation identifier and said option identifier at said central location; transmitting an encrypted feature key comprising a sequence of characters from said central location to said remote location, said encrypted feature key comprising said encrypted validation identifier and said encrypted option identifier; placing said system in a feature key entry mode; inputting said encrypted feature key into said system by operation of a sequence of input keys corresponding to said sequence of characters of said encrypted feature key; decrypting said encrypted feature key inside said system to form decrypted data comprising a decrypted validation identifier and a decrypted option identifier; comparing said decrypted validation identifier with said stored validation identifier; altering a system configuration database inside said system to reflect said change in system configuration if said decrypted validation identifier matches said stored validation identifier.
