FIELD: physics.
SUBSTANCE: invention relates to means of verifying the authenticity of a physical object or a group of physical objects. Predicted context data representing the predicted future location associated with the intended next recipient of the physical object or group of physical objects is obtained and associated future time of physical object or group of physical objects presence in this future location. Random contextual data indicating a random location and random time are obtained. Combining according to a first predetermined combination scheme of predicted context data and random context data to obtain modified context data representing a modified random location and a modified random time, each of which is obtained as a result of combination. Modified context data is encrypted to obtain a secure initial data packet representing modified context data. Protected initial data packet or stimulation to its storage is stored in the first data storage, available for provision of protected initial data packet for further protected authenticity check of physical object or group of physical objects.
EFFECT: high efficiency of verifying the authenticity of a physical object.
