摘要

The safety identification has a data matrix code (1) which is comprised with the encryption information. The individual code cells contain the scaled micro-matrix code (3), and the microcode cells are contained with additional information. The micro-matrix code is designed as a data matrix code or bar code. The micro-matrix code comprises the graphic element or text. The additional confidential information are encrypted with the combination of data matrix code and micro-matrix code. An independent claim is included for method for creating safety identification of objects.
