Using a Distributed Ledger for Tracking Debt Data
In an example embodiment described herein, there is disclosed a method for using a distributed ledger (e.g., a blockchain) for tracking debt information. For example, debt data is created by a first financial institution responsive to a loan. The debt data is stored in a distributed ledger by the first financial institution with a first key that is associated with the first financial institution. Payment data is also stored in the distributed ledger encrypted by the first key. Upon transfer of the debt to a second financial institution, subsequent debt data is stored in the distributed ledger encrypted by a second key associated with the second financial institution.
1 . A method, comprising:
storing by logic associated with a first of a plurality of financial institutions that share a distributed ledger data representative of a debt in a first block in the distributed ledger, the data representative of the debt is encrypted with a first key associated with the first financial institution;
storing data representative of the first payment in a second block of the distributed ledger by the logic associated with the first of the plurality of financial institutions data representative of a first payment encrypted with the key associated with the first financial institution;
storing data representative of a transfer of the debt from the first financial institution to a second of the plurality of financial institution in a third block of the distributed ledger; and
storing by the logic associated with the second of the plurality of financial institutions the data representative of a second payment in a fourth block of the distributed ledger, the data representative of the second payment is encrypted with a key associated with the second financial institution.
2 . The method according to claim 1 , wherein the data representative of the transfer of the debt from the first of the plurality of financial institutions to the second of the plurality of financial institutions that is stored in the third block of the distributed ledger is encrypted by a key shared by first of the plurality of financial institutions and the second of the plurality of financial institutions.
3 . The method according to claim 1 , further comprising verifying the data indicating the transfer of the debt from the first of the plurality of financial institutions to the second of the plurality of financial institutions; and
wherein verifying the data indicating the transfer of the debt from the first of the plurality of financial institutions to the second of the plurality of financial institutions comprises verifying that the data indicating the transfer of the debt from the first of the plurality of financial institutions to the second of the plurality of financial institutions was signed by the first financial institution and the second of the plurality of financial institutions.
4 . The method according to claim 1 , wherein the data representative of the debt further comprises data representative of a debtor.
5 . The method according to claim 1 , wherein the data representative of the debt further comprises data representative of an owner of the debt, where the owner of the debt is the first of the plurality of financial institutions prior to the transfer of the debt.
6 . The method according to claim 1 , wherein the data representative of the debt further comprises a balance of debt.
7 . The method according to claim 1 , wherein the data representative of the debt further comprises terms of the debt.
8 . The method according to claim 1 , wherein the data representative of the debt further comprises payment history.
9 . The method according to claim 1 , wherein the data representative of the debt further comprises status of the debt selected from a group consisting of current and overdue
10 . The method according to claim 1 , wherein the data representative of the debt further comprises a status of debt selected from group consisting of current, overdue, and severely overdue.
11 . A system, comprising:
a plurality of financial institutions having systems with logic that are operable to be in data communication with each other;
a distributed ledger that is in communication with the logic of the plurality of financial institutions;
logic associated with a first of the plurality of financial institutions is operable to receiving data representative of a debt;
the logic associated with the first of the plurality of financial institutions is operable to store the data representative of the debt in a first block in the distributed ledger, the data representative of the debt is encrypted with a first key associated with the first financial institution;
the logic associated with the first of the plurality of financial institutions is further operable to receive data representative of a first payment for the debt;
the logic associated with the first of the plurality of financial institutions is further operable to store data representative of the first payment and updated data representative of the debt in a second block of the distributed ledger, the data representative of the first payment encrypted with the key associated with the first financial institution;
the logic associated with the first of the plurality of financial institutions is further operable to provide data indicating a transfer of the debt from the first financial institution to a second financial institution;
the data representative of the debt is updated with the data representative of the transfer of the debt from the first financial institution to the second financial institution, the data representative of the debt is provided for storing in a third block of the distributed ledger by one of a group consisting of the logic associated with the first financial institution and the logic associated with the second financial institution;
the logic associated with the second financial institution is operable to receive data representative of a second payment for the debt; and
the logic associated with the second financial institution storing the data representative of the second payment in a fourth block of the distributed ledger, the data representative of the second payment is encrypted with a key associated with the second financial institution.
12 . The system according to claim 11 , the logic associated with the first financial institution and the logic associated with the second financial institution are operable to generate a shared key for storing the data representative of the transfer of the debt from the first financial institution to the second financial institution that is stored in the third block of the distributed ledger.
13 . The system according to claim 11 , further comprising logic for verifying the data indicating the transfer of the debt from the first financial institution to the second financial institution; and
wherein the logic for verifying the data indicating the transfer of the debt from the first financial institution to the second financial institution is operable to verify that the data indicating the transfer of the debt from the first financial institution to the second financial institution was signed by the first financial institution and the second financial institution.
14 . The system according to claim 11 , wherein the data representative of the debt further comprises data representative of a debtor.
15 . The system according to claim 11 , wherein the data representative of the debt further comprises data representative of an owner of the debt the owner of the debt is the first financial institution prior to the transfer of the debt.
16 . The system according to claim 11 , wherein the data representative of the debt further comprises a balance of debt.
17 . The system according to claim 11 , wherein the data representative of the debt further comprises terms of the debt.
18 . The system according to claim 11 , wherein the data representative of the debt further comprises payment history.
19 . The system according to claim 11 , wherein the data representative of the debt further comprises status of the debt selected from a group consisting of current and overdue
20 . The system according to claim 11 , wherein the data representative of the debt further comprises a status of debt selected from group consisting of current, overdue, and severely overdue.
