Abstract
Aspects of the subject disclosure may include, for example, acquiring under ambient illumination an image of a label having an encoded region and an authentication region having a random distribution of reflective particles overlaying the encoded region. The encoded message is decoded from the image. An authentication image of the label is obtained according to an image capture configuration. The authentication image includes a reflection pattern of the random distribution of reflective particles. The reflection pattern is associated with the decoded message and an authenticity of the label is determined according to the association and based on a comparison of the reflection pattern to an authenticated reference reflection pattern. Authenticity of the label is determined responsive to the comparison indicating substantial match between the reflection pattern and the authenticated reference reflection pattern. Other embodiments are disclosed.
