Abstract

The disclosed technology relates to a context service system configured to receive, from a subscriber, a shared customer lookup request that includes a first customer data identifier and identify, in a shared data partition, a second customer data identifier associated with the first customer data identifier. The context service system is further configured to determine that the second customer data identifier is associated with customer information in a subscriber data partition and transmit, to the subscriber system, the customer information from the subscriber data partition.

Claims

1. A computer-implemented method comprising:

receiving, from a subscriber system, a shared customer lookup request that includes a first customer data identifier;

identifying, in a shared data partition, a second customer data identifier associated with the first customer data identifier;

determining that the second customer data identifier is associated with a customer record in a subscriber data partition; and

providing to the subscriber system, in response to the second customer data identifier being associated with the customer record, customer information in the customer record from the subscriber data partition.

2. The computer-implemented method of claim 1, wherein the customer information is encrypted.

3. The computer-implemented method of claim 1, wherein the first customer data identifier is a first hashed value based on a shared salt value and a first element of customer information received by the subscriber system, and wherein the second customer data identifier is a second hashed value based on the shared salt value and a second element of customer information.

4. The computer-implemented method of claim 1, wherein the first customer data identifier is an element of customer information received by the subscriber system.

5. The computer-implemented method of claim 1, further comprising identifying a match between the second customer data identifier and a third customer data identifier associated with the customer record in the subscriber data partition.

6. The computer-implemented method of claim 1, further comprising:

receiving, from the subscriber system, a subscriber customer lookup request that includes a fourth customer data identifier;

determining whether the fourth customer data identifier is associated with a second customer record in the subscriber data partition; and

providing, to the subscriber system, second customer information in the second customer record from the subscriber data partition when the fourth customer data identifier is associated with the second customer record in the subscriber data partition.

7. The computer-implemented method of claim 6, wherein the fourth customer data identifier is a hashed value based on a subscriber salt value and an element of customer information received by the subscriber system.

8. The computer-implemented method of claim 1, further comprising:

calculating a confidence score for the customer record based on a timestamp associated with the customer record; and

providing the confidence score to the subscriber system.

9. The computer-implemented method of claim 1, wherein the first customer data identifier is based on one of a user name, a phone number, an email address, or an address.

10. The computer-implemented method of claim 1, wherein the subscriber data partition is associated with the subscriber system.

11. A non-transitory computer-readable medium comprising instructions, the instructions, when executed by a computing system, cause the computing system to:

receive, from a subscriber, a shared customer lookup request that includes a first customer data identifier;

identify, in a shared data partition, a second customer data identifier associated with the first customer data identifier;

determine that the second customer data identifier is associated with customer information in a subscriber data partition; and

transmit, to the subscriber, the customer information from the subscriber data partition.

12. The non-transitory computer-readable medium of claim 11, wherein the first customer data identifier is a first hashed value based on a shared salt value and a first element of customer information received by the subscriber, and wherein the second customer data identifier is a second hashed value based on the shared salt value and a second element of customer information.

13. The non-transitory computer-readable medium of claim 11, wherein the first customer data identifier is an element of customer information received by the subscriber.

14. The non-transitory computer-readable medium of claim 11, wherein the instructions further cause the computing system to identify a match between the second customer data identifier and a third customer data identifier associated with the customer information in the subscriber data partition.

15. A system comprising:

a processor;

a subscriber data partition comprising customer records associated with a subscriber;

a shared data partition comprising customer records associated with a set of subscribers; and

a non-transitory computer-readable medium storing instructions that, when executed by the system, cause the system to;

receive, from the subscriber, a shared customer lookup request that includes a first customer data identifier;

identify, in the shared data partition, a second customer data identifier associated with the first customer data identifier;

determine that the second customer data identifier is associated with customer information in the subscriber data partition; and

transmit, to the subscriber, the customer information from the subscriber data partition.

16. The system of claim 15, wherein the subscriber is a member of the set of subscribers.

17. The system of claim 15, wherein the customer information is encrypted.

18. The system of claim 15, wherein the first customer data identifier is a first hashed value based on a shared salt value and a first element of customer information received by the subscriber, and wherein the second customer data identifier is a second hashed value based on the shared salt value and a second element of customer information.

19. The system of claim 15, wherein the first customer data identifier is an element of customer information received by the subscriber.

20. The system of claim 15, wherein the instructions further cause the system to identify a match between the second customer data identifier and a third customer data identifier associated with the customer information in the subscriber data partition.
