Abstract

A method for maintaining consumer privacy in behavioral scoring includes a first computing system and a second computing system. The first computing system disguises consumer characteristics and maps disguised consumer characteristics to unencrypted account identifiers, and then transmits the data to the second computing system. The second computing system encrypts the account identifiers upon receipt, and maps the encrypted account identifiers to anonymous transaction data. The second computing system uses the transaction data to calculate consumer behavioral scores, and then generates a scoring algorithm that uses disguised consumer characteristics to calculate consumer behavior scores based on the calculated consumer behavioral scores and corresponding disguised consumer characteristics. The generated algorithm is then returned to the first computing system, with the second computing system not receiving any unencrypted account identifiers, any undisguised consumer characteristics, or any personally identifiable information.

First claim

What is claimed is:

1. A method for maintaining consumer privacy in consumer analytics, comprising:
storing, in a memory of a first computing system, a plurality of account identifiers, wherein each account identifier is associated with a payment account corresponding to a consumer;
receiving, by a receiver of the first computing system, transmitted data, wherein the transmitted data includes at least a consumer analytics request and a data file including at least a plurality of first encrypted account identifiers, wherein each first encrypted account identifier is encrypted using a first one-way encryption and is associated with a payment account corresponding to a consumer, and further including, for each first encrypted account identifier, a set of consumer characteristics associated with the consumer corresponding to the associated payment account;
disguising, by a processor of the first computing system, each set of consumer characteristics included in the received data file such that the respective set of consumer characteristics is not personally identifiable;
mapping, in the memory of the first computing system, each of the plurality of first encrypted account identifiers and corresponding disguised set of consumer characteristics to an account identifier of the plurality of account identifiers; and
transmitting, by a transmitter of the first computing system, at least each account identifier and mapped first encrypted account identifier and corresponding disguised set of consumer characteristics to a second computing system.

2. The method of claim 1 , further comprising:
receiving, by the receiver of the first computing system, consumer analytic data for each first encrypted account identifier; and
transmitting, by the transmitter of the first computing system, the consumer analytic data for each first encrypted account identifier and the corresponding first encrypted account identifier in response to the received transmitted data.

3. The method of claim 1 , further comprising:
receiving, by the receiver of the first computing system, a generated algorithm from the second computing system;
modifying, by the processor of the first computing system, the generated algorithm such that the modified algorithm is configured to calculate consumer analytics corresponding to the consumer analytics request using undisguised consumer characteristic values; and
transmitting, by the transmitter of the first computing system, at least the modified algorithm in response to the received transmitted data.

4. The method of claim 1 , wherein
the set of consumer characteristics includes variables and values, and
disguising each set of consumer characteristics includes disguising at least the included variables.

5. A system for maintaining consumer privacy in consumer analytics, comprising:
a first computing system; and
a second computing system, wherein
the first computing system includes
a memory configured to store a plurality of account identifiers, wherein each account identifier is associated with a payment account corresponding to a consumer,
a receiver configured to receive transmitted data, wherein the transmitted data includes at least a consumer analytic data request and a data file including at least a plurality of first encrypted account identifiers, wherein each first encrypted account identifier is encrypted using a first one-way encryption and is associated with a payment account corresponding to a consumer, and further including, for each first encrypted account identifier, a set of consumer characteristics associated with the consumer corresponding to the associated payment account,
a processor configured to
disguise each set of consumer characteristics included in the received data file such that the respective set of consumer characteristics is not personally identifiable, and
map each of the plurality of first encrypted account identifiers and corresponding disguised set of consumer characteristics to an account identifier of the plurality of account identifiers, and

a transmitter configured to transmit at least each account identifier and mapped first encrypted account identifier and corresponding disguised set of consumer characteristics to a second computing system.

6. The system of claim 5 , wherein
the receiver of the first computing system is further configured to receive consumer analytics data for each first encrypted account identifier, and
the transmitter of the first computing system is further configured to transmit the consumer analytics data for each first encrypted account identifier and the corresponding first encrypted account identifier in response to the received transmitted data.

7. The system of claim 5 , wherein
the receiver of the first computing system is further configured to receive a generated algorithm,
the processor of the first computing system is further configured to modify the generated algorithm such that the modified algorithm is configured to calculate consumer analytics corresponding to the behavior prediction request using undisguised consumer characteristic values, and
the transmitter of the first computing system is further configured to transmit at least the modified algorithm in response to the received transmitted data.

8. The system of claim 5 , wherein
the set of consumer characteristics includes variables and values, and
disguising each set of consumer characteristics includes disguising at least the included variables.
