System and method for use of distributed electronic wallets

Methods and systems whereby two electronic wallets communicate and exchange information. In one such system, a consumer's personal electronic wallet communicates with the exclusive or preferred wallet of a web merchant. In one such system, an internet consumer registers with a web merchant's exclusive or preferred electronic wallet (“merchant wallet”) and provides consumer information (e.g., credit card number, mailing address, and other information) to the merchant wallet, which is stored by the merchant wallet in a database on the merchant server. Such information may be automatically populated by the consumer's personal electronic wallet. The consumer maintains current consumer information in a consumer electronic wallet on the consumer's personal computer. When the consumer visits the merchant site again, and orders goods or services, the merchant's preferred wallet can be automatically updated by the consumer's electronic wallet if any of the data in the merchant's wallet has changed. For example, the consumer wallet examines the information in the merchant wallet to determine if the information in the merchant wallet conforms to the current information in the consumer wallet. If the information does not conform, the consumer wallet communicates the current consumer information to the merchant wallet.

Secure credit card having daily changed security number

A secure credit card having daily changing security number is disclosed. The upper half portion of the secure credit card has a magnet strip and its thickness is same as a normal credit card, so it can be read by a credit-card reader. The bottom half portion of the secure credit card contains a processor, key or keypad, battery, display window and a program download port. The processor is loaded with a predetermined program so that the processor can generate date and a daily renewed security number that can be shown on the display window. The security number is the function of the date and their relationship is defined by the predetermined program. Giving a date, a corresponding security number can be generated by this predetermined program. The computer of the credit card company keeps this predetermined program and can compute the security number of the date by this predetermined program. The security number of the date computed by the credit card company is identical to the security number of the date shown on the display window of the secure credit card. So that the valid of the credit card and its transaction can be verified by the credit card company based on the cardholder's name, card number and the security number of the date. With this secure credit card, the credit card payment becomes very secure even through internet.

Secure online music distribution system

A computer implemented online music distribution system provides for the secure delivery of audio data and related media, including text and images, over a public communications network. The online music distribution system provides security through multiple layers of encryption, and the cryptographic binding of purchased audio data to each specific purchaser. The online music distribution system also provides for previewing of audio data prior to purchase. In one embodiment, the online music distribution system is a client-server system including a content manager, a delivery server, and an HTTP server, communicating with a client system including a Web browser and a media player. The content manager provides for management of media and audio content, and processing of purchase requests. The delivery server provides delivery of the purchased media data. The Web browser and HTTP server provide a communications interface over the public network between the content manager and media players. The media player provides for encryption of user personal information, and for decryption and playback of purchased media data. Security of purchased media data is enhanced in part by the use of a personal, digital passport in each media player. The digital passport contains identifying information that identifies the purchaser, along with confidential information, such as credit card number, and encryption data, such as the media player's public and private keys. The media player encryption data is used to encrypt purchased media data, which is decrypted in real time by the media player. The media player also displays confidential information, such as the purchaser's credit card number, during playback.

Method for generating customer one-time unique purchase order numbers

Multiple secure transactions are provided through use of a method that uses customer one-time unique purchase order numbers (“Coupons”) generated by an algorithm that uses a permutated user key and a user insertion key as input variables. A user key (such as a Personal Identification Number, or “PIN”) is combined with a permutation variable that is correlated with a customer sequence number to create the permutated user key. A random number generator is used to generate the user insertion key correlated with the customer sequence number. The algorithm can insert the permutated user key into a user account number through use of the user insertion key. A Coupon is validated by confirming that it is contained in a set of money source Coupons generated by a money source using the user key and a random number generator that is synchronized with the random number used to generate Coupons. Once a Coupon is validated, the matching money source Coupon and all earlier generated money source Coupons are deleted from the set, and a new set is generated. If a preselected number of Coupons are not validated for a chosen entity, an invalid user account number will be set. Coupons can be used for credit card or bank card transactions, and they can be generated without changing fixed digits of traditional twenty digit account numbers.
