Abstract
A method for authentication of user reviews includes providing a user certificate to a user's mobile device. A transaction log is received from the mobile device. The transaction log includes an encrypted tag identifier which has been transmitted to the mobile device from a review tag at a location where a service is provided by a service provider when the review tag has verified the validity of the user certificate. The encrypted tag identifier is decrypted to identify the service provider. The user is prompted to submit a review of the service provided by the service provider.
