Abstract
Aspects described herein may provide detection of a feature of an authorization code image (ACI) incorporated onto a document, thereby allowing for validation of the document. According to some aspects, these and other benefits may be achieved by an instance of a variable protocol that may specify how to generate the ACI to have a particular feature as well as how to detect the particular feature of the ACI. A recipient of the document incorporating the ACI may detect the particular feature of the ACI. If the detected feature matches an expected feature, then the ACI and the document may be determined to be authentic.
