A method for providing secure credit card transactions over the Internet generates a personal charge number from a user account number by inserting a user key into the user account number in accordance with an algorithm that uses a user insertion key and a permutation variable. After the personal charge number is used, the permutation variable is changed, and a new personal charge number is generated. A money source repository verifies the validity of the personal charge number by using the personal charge number and a user identifier to access a file with the user account number, the user key and the user insertion key, taking into account which permutation variable is valid at a given point in time. Alternatively, the money source repository could generate a string of valid personal charge numbers for a user which are sequentially accessed according to usage.

[ What is claimed:] [1.] A method for providing secure transactions between a first entity and at least one additional entity, comprising the steps of:(1) assigning a user account number to the first entity;(2) generating a record associated with the first entity with a money source repository which includes the user account number of the first entity, a user key, a user insertion key and a first entity identifier;(3) generating a personal charge number from the user account number by inserting the user key into the user account number in accordance with an algorithm that uses the user insertion key and a permutation variable;(4) transferring the personal charge number and the first entity identifier to a second entity;(5) transmitting the personal charge number, the first entity identifier, a transaction monetary value and a second entity identifier from the second entity to the money source;(6) verifying that the personal charge number is valid for the first entity;(7) providing the second entity with a monetary credit associated with the transaction monetary value; and(8) charging the first entity with a charged credit associated with the transaction monetary value.
