Abstract: Credit card or portable identification cards containing smart card technology and electronic fuse (e-fuse) technology are combined with an LFSR pseudo random number generator to provide a secured method to prevent fraud and unauthorized use. Secure personalization via e-fuses, a pseudo-random number generator linear feedback shift register, free running clock oscillator, and power source embedded in the card provide a highly secured method to render a lost or stolen card useless. A unique card ID is permanently encoded within the card which requires a specific activation code to activate the card. A PIN number permits the card owner to activate the card for a predetermined length of time while processing a transaction. The card dynamically generates random code sequences and synchronization keys to secure a transaction.
TL;DR: In this article, a system and method of the present invention enables consumers to purchase goods and services from merchants, using credit cards, wherein the consumers can maintain the confidentiality of their credit card numbers and identity without disclosure to the merchants, so that an anonymous credit transaction can take place.
Abstract: The system and method of the present invention enables consumers to purchase goods and services from merchants, using credit cards, wherein the consumers can maintain the confidentiality of their credit card numbers and identity without disclosure to the merchants, so that an anonymous credit transaction can take place. The system and method takes blocks of consumer credit card numbers and creates dynamic mappings of the card numbers to account numbers or even other card numbers, such as pseudo-random credit card numbers. The system and method of the present invention generates pseudo-random credit cart attributes, which are presented to merchants at the time or purchase for Internet, telephone, or mail order purchases. Because pseudo-random attributes are transmitted to the merchant, the transaction between the consumer and merchant will be anonymous. Pseudo-random attributes include the card number, name, billing zip code, expiration date, and purchase amount, each of which can be used singularly or in combination to authenticate a transaction according to consumer preferences, which are captured when the consumer establishes the agent relationship with system of the present invention.
