A simple and quick verification of the authenticity of a blister of elements, such as pills in the pharmaceutical industry, is provided. The pills packaged in a blister can be authenticated using mobile imaging devices such as a mobile smartphone. Generally speaking, an image of the pills and their differentiating physical characteristics in the blister is acquired and compared to at least one code which is marked on the blister itself. This code may also be encrypted. A dedicated software application on the mobile smartphone can be used to decrypt the code and compare the code to the image of the pills in the blister, to thereby evaluate authenticity of the blister and its contents.
