Abstract

A method for checking legitimacy of a customer review includes receiving, via a service provider device, a verification key and receiving, via a customer device, a customer review, a redacted message, and a redacted signature. The method further includes at least one of: (a) publishing the verification key and the redacted signature on a review website with the customer review such that the legitimacy of the redacted signature is checkable by a user device; or (b) checking, using the verification key, whether the redacted signature is legitimate and, based on the redacted signature being legitimate, marking the customer review as being legitimate.

First claim

What is claimed is:

1 . A method for checking legitimacy of a customer review, the method comprising:
receiving, via a service provider device, a verification key; receiving, via a customer device, a customer review, a redacted message, and a redacted signature; and at least one of: publishing the verification key and the redacted signature on a review website with the customer review such that the legitimacy of the redacted signature is checkable by a user device; or checking, using the verification key, whether the redacted signature is legitimate and, based on the redacted signature being legitimate, marking the customer review as being legitimate.

2 . The method according to claim 1 , wherein the redacted message includes a list of purchased goods and services and/or a serial number.

3 . The method according to claim 2 , wherein the redacted message includes the serial number, the method further comprising a second check that the customer review is legitimate by checking a database of previously-encountered serial numbers to determine whether the serial number is present.

4 . The method according to claim 1 , further comprising uploading the legitimate customer review to a review website.

5 . The method according to claim 1 , further comprising storing the customer review in a review database based on the checking determining that the redacted signature is legitimate and not storing the customer review in the database based on the checking determining that the redacted signature is not legitimate.

6 . A method for providing a legitimate customer review, the method comprising:
receiving, via a service provider device, an authorization token, wherein the authorization token includes a message, a redactable signature, and an encoding of redactable parts of the message; redacting part of the message, based on the encoding of redactable parts, to create a redacted message; generating a redacted signature using the redactable signature; and providing the redacted message, the redacted signature, and a customer review to a review server.

7 . The method according to claim 6 , wherein the message includes a list of purchased goods and services, a serial number that uniquely identifies the redactable signature, and/or a timestamp indicating when the redactable signature was issued.

8 . The method according to claim 7 , wherein the encoding of the redactable parts of the message indicates that one or more of the purchased goods and services are to be redacted in the redacted message.

9 . The method according to claim 6 , wherein the authorization token is received via scanning a quick response (QR) code printed on a receipt and/or displayed on the service provider device.

10 . The method according to claim 6 , wherein the authorization token is received via near field communication (NFC) and/or through electronic messaging.

11 . The method according to claim 6 , wherein the redacted message is the same as the message and the redacted signature is the same as the redactable signature.

12 . The method according to claim 6 , wherein the redactable signature was generated using a private key and the redacted signature is generated based on the redacted message and on a result of verifying the redactable signature with a public key.

13 . The method according to claim 6 , wherein the review server facilitates provision of a review website, and the redacted message, the redacted signature, and the customer review are provided on the review website such that validity of the redacted signature is verifiable by a user device.

14 . A trustworthy review system for verifying that a customer review is legitimate, the system comprising a review server having one or more processors which, alone or in combination are configured to provide for performance of the following steps:
receiving, via a service provider device, a verification key; receiving, via a customer device, a customer review, a redacted message, and a redacted signature; and at least one of:
publishing the verification key and the redacted signature on a review website with the customer review such that the legitimacy of the redacted signature is checkable by a user device; or
checking, using the verification key, whether the redacted signature is legitimate and, based on the redacted signature being legitimate, marking the customer review as being legitimate.

15 . The trustworthy review system according to claim 15 , further configured to store the customer review in a review database based on the checking determining that the redacted signature is legitimate and to not store the customer review in the database based on the checking determining that the redacted signature is not legitimate.
