Abstract
Techniques are described for generating a seal that is applicable to an object, and scanning the seal to access encoded data to be used for verifying one or more characteristics of the object. The seal may be applied to a tangible document, such as a document printed on paper. The seal may encode data that is particularly associated with the document. For example, the seal may encode a hash of at least a portion of the information (e.g., text) included in the document. In some instances, the seal may encode a digital version and/or metadata of at least a portion of the information in the document. A scan of the seal may retrieve information useable to verify the authorship, provenance, originality, and/or unaltered contents of the documents. In some instances, the seal may encode information that enables the presentation of hidden information and/or metadata associated with the document.
