Creating a secure digital identity

1. A computer-implemented method for creating a verifiable digital identity, comprising:

obtaining a first user-generated item generated through a device, the first user-generated item comprising an identifiable feature of a user;

digitally signing the first user-generated item with the device to generate a secure digital artifact;

uploading the secure digital artifact and the first user-generated item to an auditable chain of a public ledger, the public ledger comprising a database;

verifying a digital identity of the user by auditing the auditable chain;

obtaining a second user-generated item generated through the device, the second user-generated item comprising the identifiable feature of the user;

comparing the identifiable feature of the user from the first user-generated item and the second user-generated item; and

uploading the second user-generated item to the public ledger when the comparing is within a threshold, the second user-generated item hashed with the first user-generated item to create a link in the auditable chain.

2. The computer-implemented method of claim 1 , wherein verifying the device comprises:

establishing a form of authentication for the device, the form of authentication comprising at least one of a password, an audio signature, or a biometric input, the biometric input comprising a fingerprint or facial recognition.

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

obtaining sensor data associated with the first user-generated item.

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

obtaining a multi-user generated item generated through the device, the multi-user generated item comprising identifiable features of at least two users.

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

certifying a transaction upon verification of the digital identity.

6. A system for creating a verifiable digital identity, comprising:

a memory storing sequences of instructions; and

a processor configured to execute the sequences of instructions which, when executed, causes the processor to perform:

obtaining a first user-generated item generated through a device, the first user-generated item comprising an identifiable feature of a user;

digitally signing the first user-generated item with the device to generate a secure digital artifact;

uploading the secure digital artifact and the first user-generated item to an auditable chain of a public ledger, the public ledger comprising a database; and verifying a digital identity of the user by auditing the auditable chain;

obtaining a second user-generated item generated through the device, the second user-generated item comprising the identifiable feature of the user;

comparing the identifiable feature of the user from the first user-generated item and the second user-generated item; and

uploading the second user-generated item to the public ledger when the comparing is within a threshold, the second user-generated item hashed with the first user-generated item to create a link in the auditable chain.

7. The system of claim 6 , wherein verifying the device comprises:

establishing a form of authentication for the device, the form of authentication comprising at least one of a password, an audio signature, or a biometric input, the biometric input comprising a fingerprint or facial recognition.

8. The system of claim 6 , further comprising stored sequences of instructions, which when executed by the processor, cause the processor to perform:

obtaining sensor data associated with the first user-generated item.

9. The system of claim 6 , further comprising:

obtaining a multi-user generated item generated through the device, the multi-user generated item comprising identifiable features of at least two users.

10. The system of claim 6 , further comprising stored sequences of instructions, which when executed by the processor, cause the processor to perform:

certifying a transaction upon verification of the digital identity.

11. A non-transitory computer-readable storage medium is provided including instructions that, when executed by a processor, cause the processor to perform a method for creating a verifiable digital identity, the method comprising:

obtaining a first user-generated item generated through a device, the first user-generated item comprising an identifiable feature of a user;

digitally signing the first user-generated item with the device to generate a secure digital artifact;

uploading the secure digital artifact and the first user-generated item to an auditable chain of a public ledger, the public ledger comprising a database;

verifying a digital identity of the user by auditing the auditable chain;

obtaining a second user-generated item generated through the device, the second user-generated item comprising the identifiable feature of the user;

comparing the identifiable feature of the user from the first user-generated item and the second user-generated item; and

uploading the second user-generated item to the public ledger when the comparing is within a threshold, the second user-generated item hashed with the first user-generated item to create a link in the auditable chain.

12. The non-transitory computer-readable storage medium of claim 11 , wherein the method comprises:

establishing a form of authentication for the device, the form of authentication comprising at least one of a password, an audio signature, or a biometric input, the biometric input comprising a fingerprint or facial recognition.

13. The non-transitory computer-readable storage medium of claim 11 , wherein the method further comprises:

obtaining sensor data associated with the first user-generated item.
