Abstract: Detection of human consciousness is vital for validating a legal or official statement whether in the form of written or verbal. A statement given under unconsciousness state is considered null and void as the person is not fully awarded about the consequences of the statement. Several factors affects human consciousness like effect of alcohol, drowsiness, effect of anesthesia, sleeping pills, natural sleeping hours etc. The present available methods for detection of level of consciousness works in a specific condition only. For instance Alcohol Meter can detect the level of alcohol in the breath but not the effects sleeping pills or partial conscious due to drowsiness. In this research we propose a new technique which can detect all types of unconsciousness irrespective of reasons. We used the feature of iris light sensitivity which dilates inversely to pupil. Consciousness and iris dilation is directly proportional i.e. iris dilation increases with increase of consciousness and decreases with decrease of consciousness. We tested this method on 66 volunteers with 99.83% accuracy for 0.03mm iris dilation threshold value unconscious under alcohol effect and under drossiness conditions. Results shows that iris sensitivity decreases significantly during unconscious state, for any reasons. This feature can be used for validation of contracts before signing legal contracts.
