Abstract
A method for generating a matrix barcode key combination. The method includes receiving a request to secure at least a portion of data. In response to receiving the request to secure at least a portion of data, the method includes generating a matrix barcode that encodes the data, based on at least a first portion of content of the data. The method includes generating a matrix barcode key based on at least another portion of the content of the data. The method includes aligning the matrix barcode key with at least a portion of the matrix barcode to provide a matrix barcode key combination. The method includes enabling a requesting device to have access to the secured portion of encoded data, when the requesting device presents the matrix barcode key in an arrangement that aligns the matrix barcode key with the matrix barcode resulting in the matrix barcode key combination.
