Abstract
This paper presents the original concept of inserting a person's identity data into a photo. Prior to insertion, the identification data is encoded with a two-dimensional QR code. The resulting QR code is a binary watermark that is inserted into a person's color photo. Specialized algorithms based on the YCbCr color model and block SVD transformation have been developed for inserting and extracting QR code from photo. The presented concept can be classified into multi-modal identification because it allows instant link between the appearance and identity of a person. The advantage of the presented concept is reflected in the fact that the creation of an identification document can be done in the field without the need for a network connection. The results of the experiment confirm that the presented concept can be successfully used in the identification of persons in the field without the need to have a network connection.
