Abstract

The invention is a method for creating one time-use highly secure 2D barcodes, or secure two-dimensional barcodes, by utilizing machine readable physical tokens such as read only memory (ROM) or biometric data as a precursor and then applying a public key encryption algorithm and a time-stamp to otherwise standard 2D barcode generation schemas.

Claims

1. ) A method for creating a secure two-dimensional bar code by capturing and utilizing any number of different physical machine-readable precursor tokens, for example unique read only memory (ROM) or biometric datum, and applying an encryption algorithm such as PKI to generate otherwise normal two-dimensional bar codes on a one-time basis

2. ) A method of claim 1, for time-stamping in a globally synchronized fashion all secure two dimensional codes to allow discriminate use of the code, in accepting or rejecting them for authentication purposes, dependent upon expiry time.

3. ) A method of claim 1, to Anonymise easily captured and highly recognizable biometrics identifiers, such as the digital image of a person'"'"'s face, to protect the personal privacy of individuals when such a biometrics is to be used as a precursor authentication token.

4. ) A method for authenticating mobile device users by reading or capturing with normal bar code scanners and/or digital cameras unique identity token(s) datum which have been encrypted and incorporated into visibly displayed otherwise normal two-dimensional bar codes and communicating the captured datum to computer servers over the internet which are able to decrypt and verify said unique identity token(s) datum thus enabling said two-dimensional codes to be used for authentication purposes in electronic commerce.
