Abstract

Claims (46)

1. A method for generating a consumer profile, comprising:

receiving, via a server, a purchase authorization request including a card number from a consumer;

generating, with a key module, a hash value of the card number;

generating, at the server, a card identifier;

associating the generated card identifier with the generated hash value;

storing, at a server database, the associated card identifier; and

associating, with a processor, the card identifier with the consumer profile;

wherein the card identifier is generated in a sequential integer increment with respect to a previously generated card identifier.

2. The method of claim 1 , further comprising:

receiving, via the server, a purchase authorization request including a consumer identifier from the consumer; and

associating, with the processor, the consumer identifier with the consumer profile.

3. The method of claim 2 , further comprising associating the consumer identifier with the generated card identifier.

4. The method of claim 1 , further comprising:

encrypting, with an encryption module, the generated hash value,

wherein the card identifier is associated with the encrypted hash value.

5. The method of claim 1 , further comprising:

storing, at the key manager database, the generated hash value; and

associating, with the processor, the generated hash value with the consumer profile.

6. A system for tracking purchases with a consumer profile, comprising:

a key manager module, including a hash value generator configured to generate a plurality of hash values from card numbers included in purchase authorization requests from consumers;

an association module configured to associate the plurality of hash values with a plurality of consumer profiles; and

a server configured to receive purchase authorization requests from the consumer, the server including:

a server database that stores the plurality of consumer profiles; and

a determination module configured to, when the purchase authorization request does not include a consumer identifier:

determine, with the plurality of consumer profiles stored in the server database and a hash value of a card number included in the purchase authorization request, whether the hash value is associated with one of the plurality of consumer profiles; and

update a purchase history of the one of the plurality of consumer profiles when it is determined that the hash value is associated with the one of the plurality of consumer profiles

wherein each of the plurality of card identifiers is generated in a sequential integer increment with respect to a previously generated card identifier of the plurality of card identifiers.

7. The system of claim 6 , further comprising:

a card identifier generator configured to generate a plurality of card identifiers;

wherein the association module is further configured to associate the plurality of card identifiers with the plurality of hash values and the plurality of consumer profiles; and

wherein the determination module is further configured to determine whether the hash value is associated with one of the plurality of consumer profiles by determining whether the hash value of the card number included in the purchase authorization request is associated with one of the plurality of card identifiers.

8. The system of claim 6 , wherein the key manager module further comprises an encryption module configured to encrypt the generated hash values.

9. The system of claim 6 , wherein the association module is configured to associate the plurality of hash values with the plurality of consumer profiles via a plurality of card identifiers generated by a card identifier generator, each of the plurality of card identifiers being associated with one of the plurality of hash values.

10. The system of claim 6 , wherein the determination module is further configured to, when the purchase authorization request includes a consumer identifier:

determine, with the plurality of consumer profiles stored in the server database, whether the consumer identifier is associated with one of the plurality of consumer profiles; and

update a purchase history of the one of the plurality of consumer profiles when it is determined that the consumer identifier is associated with one of the plurality of consumer profiles.

11. The system of claim 10 , wherein the determination module is configured to, if the consumer identifier is not associated with one of the plurality of consumer profiles:

generate a new consumer profile;

associate the consumer identifier with the new consumer profile; and

store, in the server database, the new consumer profile as one of the plurality of consumer profiles.

12. The system of claim 6 , wherein the server is configured to, if the determination module determines the hash value of the card number included in the authorization request is not associated with one of the plurality of consumer profiles:

generate a new consumer profile;

generate, via a card identifier generator, a card identifier;

associate, via the association module, the card identifier with the hash value of the card number included in the authorization request;

associate the card identifier with the new consumer profile; and

store, in the server database, the new consumer profile as one of the plurality of consumer profiles.
