Abstract

In some examples, Blockchain intelligent security implementation may include determining whether a Blockchain transaction has been initiated, generating, based on a determination that the Blockchain transaction has been initiated, a password, and storing the generated password. The stored password may be forwarded to a user associated with the Blockchain transaction. A further password may be received from the user associated with the Blockchain transaction, and validated, based on comparison of the stored password to the further password. Based on the validation of the further password, the Blockchain transaction may be processed.

First claim

What is claimed is:

1. A Blockchain intelligent security implementation apparatus comprising:
a Blockchain transaction analyzer, executed by at least one hardware processor, to
determine whether a Blockchain transaction has been initiated;

a password generator, executed by the at least one hardware processor, to
generate, based on a determination that the Blockchain transaction has been initiated and by a Blockchain associated with the Blockchain transaction, a password;

a password recorder, executed by the at least one hardware processor, to
store the generated password;

a password communicator, executed by the at least one hardware processor, to
forward, from the Blockchain, the stored password to a user associated with the Blockchain transaction;

a password validator, executed by the at least one hardware processor, to
receive, at the Blockchain, a further password from the user associated with the Blockchain transaction,
ascertain, at the Blockchain, the Blockchain transaction;
generate, based on the ascertained Blockchain transaction and by the Blockchain, a new password, and
validate, based on comparison of the stored password and the new password to the further password received from the user associated with the Blockchain transaction, the further password; and

a Blockchain transaction processor, executed by the at least one hardware processor, to
process, based on the validation of the further password, the Blockchain transaction.

2. The apparatus according to claim 1 , wherein the password generator is executed by the at least one hardware processor to generate, based on the determination that the Blockchain transaction has been initiated and by the Blockchain associated with the Blockchain transaction, the password by:
ascertaining a plurality of user inputs associated with the user associated with the Blockchain transaction;
ascertaining a hash of a previous block associated with the Blockchain transaction; and
generating the stored password by
performing a hash operation on the plurality of user inputs associated with the user associated with the Blockchain transaction, and
performing a hash operation on the hash of the previous block associated with the Blockchain transaction.

3. The apparatus according to claim 2 , wherein the plurality of user inputs include at least two of:
a user identification associated with the user associated with the Blockchain transaction;
an input from the user associated with the Blockchain transaction;
a latest sequence number of the user associated with the Blockchain transaction; or
a seed value for a deterministic component of the stored password.

4. The apparatus according to claim 1 , wherein the stored password includes a deterministic component and a random component.

5. The apparatus according to claim 1 , wherein the password recorder is executed by the at least one hardware processor to store the generated password by:
mapping the generated password to a Blockchain transaction identification; and
storing the generated password in association with the Blockchain transaction identification.

6. The apparatus according to claim 1 , wherein the password communicator is executed by the at least one hardware processor to forward, from the Blockchain, the stored password to the user associated with the Blockchain transaction by:
generating a short message service (SMS) message that includes the stored password; and
forwarding, from the Blockchain associated with the Blockchain transaction, the SMS message to the user associated with the Blockchain transaction.

7. The apparatus according to claim 6 , wherein the password communicator is executed by the at least one hardware processor to generate the SMS message that includes the stored password by:
generating the SMS message that includes the stored password, user information associated with the user associated with the Blockchain transaction, and transaction information associated with the Blockchain transaction.

8. The apparatus according to claim 1 , wherein the password validator is executed by the at least one hardware processor to validate, based on comparison of the stored password and the new password to the further password received from the user associated with the Blockchain transaction, the further password by:
determining, based on the comparison of the stored password and the new password to the further password received from the user associated with the Blockchain transaction, whether the stored password matches the further password;
based on a determination that the stored password and the new password do not match the further password, generating a validation failure indication; and
based on a determination that the stored password and the new password match the further password, generating a validation approval indication.

9. A method for Blockchain intelligent security implementation, the method comprising:
determining, by at least one hardware processor, whether a Blockchain transaction has been initiated;
generating, by the at least one hardware processor, based on a determination that the Blockchain transaction has been initiated, and by a Blockchain associated with the Blockchain transaction, a password that includes a deterministic component and a random component;
storing, by the at least one hardware processor, the generated password;
forwarding, by the at least one hardware processor and from the Blockchain, the stored password to a user associated with the Blockchain transaction;
receiving, by the at least one hardware processor and at the Blockchain, a further password from the user associated with the Blockchain transaction;
ascertaining, by the at least one hardware processor and at the Blockchain, the Blockchain transaction;
generating, by the at least one hardware processor, based on the ascertained Blockchain transaction, and by the Blockchain, a new password;
validating, by the at least one hardware processor and based on comparison of the stored password and the new password to the further password received from the user associated with the Blockchain transaction, the further password; and
processing, by the at least one hardware processor and based on the validation of the further password, the Blockchain transaction.

10. The method according to claim 9 , wherein generating, by the at least one hardware processor, based on the determination that the Blockchain transaction has been initiated, and by the Blockchain associated with the Blockchain transaction, the password that includes the deterministic component and the random component further comprises:
ascertaining, by the at least one hardware processor, a plurality of user inputs associated with the user associated with the Blockchain transaction;
ascertaining, by the at least one hardware processor, a hash of a previous block associated with the Blockchain transaction;
generating, by the at least one hardware processor, the deterministic component of the stored password by performing a hash operation on the plurality of user inputs associated with the user associated with the Blockchain transaction; and
generating, by the at least one hardware processor, the random component of the stored password by performing a hash operation on the hash of the previous block associated with the Blockchain transaction.

11. The method according to claim 10 , wherein the plurality of user inputs include at least two of:
a user identification associated with the user associated with the Blockchain transaction;
an input from the user associated with the Blockchain transaction;
a latest sequence number of the user associated with the Blockchain transaction;
