Cryptographically generating custom audiences
The disclosed computer-implemented method may include (1) accessing, by a computing device and from a record stored in an immutable distributed ledger, information describing characteristics of a target audience, (2) ascertaining a target audience member identifier of a target audience member by matching information describing characteristics of the target audience member with the information describing characteristics of the target audience, (3) generating a unique and encrypted secure identifier linking an advertiser identifier to the target audience member identifier, and (4) committing the secure identifier to the immutable distributed ledger as an update transaction to the record. Various other methods, systems, and computer-readable media are also disclosed.
1. A computer-implemented method, comprising:
accessing, by a computing device and from a record stored by an advertiser in an immutable distributed ledger, information describing characteristics of a target audience;
ascertaining a target audience member identifier of a target audience member by matching information describing characteristics of the target audience member with the information describing characteristics of the target audience;
generating a unique and encrypted secure identifier linking an advertiser identifier associated with the advertiser to the target audience member identifier; and
committing the secure identifier to the immutable distributed ledger as an update transaction to the record.
2. The computer-implemented method of claim 1 , wherein the immutable distributed ledger implements a blockchain methodology configured to store a history of transactions.
3. The computer-implemented method of claim 1 , further comprising receiving, from a second computing device, an instruction to initiate the accessing.
4. The computer-implemented method of claim 1 , wherein the information describing characteristics of the target audience is personally identifiable identification of the target audience.
5. The computer-implemented method of claim 1 , wherein the information describing characteristics of the target audience is encrypted with a cryptographic key.
6. The computer-implemented method of claim 1 , wherein the secure identifier is cryptographically signed by the computing device.
7. The computer-implemented method of claim 1 , further comprising sending, to a second computing device, a communication indicating storing of the secure identifier as the update transaction.
8. The computer-implemented method of claim 1 , further comprising disabling use of the secure identifier at least one of:
after a defined period of time following the generating of the secure identifier; or
in response to a triggered condition of a smart contract.
9. The computer-implemented method of claim 1 , wherein the secure identifier includes information describing at least one of:
the target audience member identifier;
row-level personally identifiable identification describing characteristics of the target audience;
the advertiser identifier;
an expiration date of the secure identifier; or
a digital signature.
10. The computer-implemented method of claim 1 , wherein
generating the unique and encrypted secure identifier further includes hashing the target audience member identifier with the advertiser identifier to form the secure identifier.
11. The computer-implemented method of claim 1 , further comprising:
receiving, from a second computing device, a request for an access transaction to grant access to the record;
sending, to a plurality of node devices of a validation network, a request to validate the access transaction;
receiving responses from the plurality of node devices of the validation network;
denying the access transaction when any response indicates the access transaction is invalid; and
executing the access transaction when all responses indicate the access transaction is valid.
12. The computer-implemented method of claim 11 , further comprising:
receiving, when the access transaction is valid and from the second computing device, the target audience member identifier and a request to send an advertisement to the target audience member associated with the target audience member identifier; and
sending the advertisement to a user device of the target audience member.
13. A system, comprising:
a computing device having a memory;
an accessing module, stored in the memory, that accesses information describing characteristics of a target audience from a record stored by an advertiser in an immutable distributed ledger;
an ascertaining module, stored in the memory, that ascertains a target audience member identifier of a target audience member by matching information describing characteristics of the target audience member with the information describing characteristics of the target audience;
a generating module, stored in the memory, that generates a unique and encrypted secure identifier linking an advertiser identifier associated with the advertiser to the target audience member identifier; and
a committing module, stored in the memory, that commits the secure identifier to the immutable distributed ledger as an update transaction to the record.
14. The system of claim 13 , wherein the information describing characteristics of the target audience is personally identifiable identification of the target audience.
15. The system of claim 13 , further comprising a disabling module, stored in the memory, that disables use of the secure identifier at least one of:
after a defined period of time following the generating of the secure identifier; or
in response to a triggered condition of a smart contract.
16. The system of claim 13 , wherein the secure identifier includes information describing at least one of:
the target audience member identifier;
row-level personally identifiable identification describing characteristics of the target audience;
the advertiser identifier;
an expiration date of the secure identifier; or
a digital signature.
17. A non-transitory computer-readable medium, comprising:
computer-readable instructions that, when executed by at least one processor of a computing device, cause the computing device to:
access from a record stored by an advertiser in an immutable distributed ledger, information describing characteristics of a target audience;
ascertain a target audience member identifier of a target audience member by matching information describing characteristics of the target audience member with the information describing characteristics of the target audience;
generate a unique and encrypted secure identifier linking an advertiser identifier associated with the advertiser to the target audience member identifier; and
commit the secure identifier to the immutable distributed ledger as an update transaction to the record.
18. The non-transitory computer-readable medium of claim 17 , wherein the information describing characteristics of the target audience is personally identifiable identification of the target audience.
19. The non-transitory computer-readable medium of claim 17 , wherein the computer-readable instructions, when executed by the at least one processor of the computing device, further cause the computing device to disable use of the secure identifier at least one of:
after a defined period of time following the generating of the secure identifier; or
in response to a triggered condition of a smart contract.
20. The non-transitory computer-readable medium of claim 17 , wherein the secure identifier includes information describing at least one of:
the target audience member identifier;
row-level personally identifiable identification describing characteristics of the target audience;
the advertiser identifier;
an expiration date of the secure identifier; or
a digital signature.
