Abstract
A method for providing a document using a secure bar code includes encrypting the document to generate an encrypted document, and mixing together bits for a security credential with bits for the encrypted document to generate a set of mixed bits having a predetermined order. The security credential is for decrypting the encrypted document. The method further includes inserting the set of mixed bits into the secure bar code and outputting the secure bar code. A bar code reader knows the predetermined order and is configured to read the secure bar code. The bar code reader may also be configured to un-mix the mixed bits based on the predetermined order, and decrypt the encrypted document with the security credential.
