responsive to a requestor accessing a verification website to make a request for verification, providing requested information to the verification website in accordance with website instructions;

calculating, by a verification algorithm running on a processor, a request hash for the requested information;

responsive to scanning the barcode on the payslip, accessing the at least one hash in the blockchain transaction;

responsive to accessing the at least one hash in the blockchain transaction, comparing the request hash to the at least one hash in the blockchain transaction;

responsive to the request hash matching the at least one hash in the blockchain transaction, verifying that the payslip is genuine;

responsive to verifying that the payslip is genuine, delivering a first message to the verification website wherein the first message verifies that the payslip is genuine; and

recording a result.

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

responsive to the request hash not matching the at least one hash in the blockchain transaction, determining that the payslip is not a genuine payslip;

responsive to determining that the payslip is not genuine, delivering a second message to the verification website wherein the second message informs the requestor to check the requested information; and

recording a result.

3. The computer-implemented method of claim 2 , further comprising:

storing the at least one portion of the information in the payslip at an off-blockchain location.

4. The computer-implemented method of claim 3 , wherein the off-blockchain location comprises a source in a database.

5. The computer-implemented method of claim 2 , wherein the pay slip is a digital payslip.

6. The computer-implemented method of claim 2 , wherein the pay slip is printed on paper.

7. The computer-implemented method of claim 1 , wherein the verification website is configured to provide a pay-per-use service to the requestor, and wherein the pay-per-use service includes providing a history of verification.

8. An apparatus for payslip verification, the apparatus comprising:

a computer system connected to a blockchain and to a verification website; and

a computer-readable storage medium having program code stored thereon, wherein the program code is configured to cause a processor unit to configure the blockchain for:

recording transactions;

preparing a payslip, the payslip having information regarding an employee, the information comprising a start date of pay period, an end date of pay period, a payment date, an employee number, and a social security number;

providing at least one hash for a portion of the information;

recording the at least one hash and the portion of the information in the blockchain as a blockchain transaction;

responsive to configuring a barcode as a pointer for locating the blockchain transaction, to insert the barcode into a barcode location on the payslip in response to configuring the barcode;

delivering the payslip to the employee;

responsive to a requestor accessing the verification website to make a request for verification, providing requested information to the verification website in accordance with website instructions;

calculating, by a verification algorithm running on a processor, a request hash for the requested information;

responsive to a scan of the barcode location on the payslip, accessing the at least one hash in the blockchain transaction;

responsive to accessing the at least one hash in the blockchain transaction, comparing the request hash to the at least one hash in the blockchain transaction;

responsive to the request hash matching the at least one hash in the blockchain transaction, verifying that the payslip is a genuine payslip;

responsive to verifying that the payslip is the genuine payslip, delivering a first message to the verification website wherein the first message verifies that the payslip is genuine; and

recording a result.

9. The apparatus of claim 8 , further comprising:

program code stored in the computer-readable storage medium and configured to cause the processor unit to:

responsive to the request hash not matching the at least one hash in the blockchain transaction, determining that the payslip is not a genuine payslip;

responsive to determining that the payslip is not genuine, deliver a second message to the verification website wherein the second message informs the requestor to check the requested information; and

record a result.

10. A computer program product for reducing fraud based on a forged or altered payslip, the computer program product comprising:

program code stored in a computer-readable storage medium and configured to cause a processor unit to configure a blockchain for recording transactions;

program code stored in the computer-readable storage medium and configured to cause the processor unit to prepare a payslip, the payslip having information regarding an employee, the information comprising a start date of pay period, an end date of pay period, a payment date, an employee number, and a social security number;

program code stored in the computer-readable storage medium and configured to cause the processor unit to provide at least one hash for a portion of the information;

program code stored in the computer-readable storage medium and configured to cause the processor unit to record the at least one hash and the portion of the information in the blockchain as a blockchain transaction;

program code stored in the computer-readable storage medium and configured to cause the processor unit to configure a barcode as a pointer for locating the blockchain transaction;

program code stored in the computer-readable storage medium and configured to cause the processor unit, to insert the barcode into a barcode location on the payslip in response to configuring the barcode;

program code stored in the computer-readable storage medium and configured to cause the processor unit to deliver the payslip to the employee;

program code stored in the computer-readable storage medium and configured to cause the processor unit, responsive to a requestor accessing a verification website to make a request for verification, providing requested information to the verification website in accordance with website instructions;

program code stored in the computer-readable storage medium and configured to cause the processor unit to calculate, by a verification algorithm running on a processor, a request hash for the requested information;

program code stored in the computer-readable storage medium and configured to cause the processor unit, responsive to scanning the barcode location on the payslip, to access the at least one hash in the blockchain transaction;
