Weapon Authentication and Control System Using Palm Image Verfication

C.A.Devi

A system designed to prevent people from accessing firearms such as guns or pistols of an authorized person, so that the fire arms are not misused. In many cases these arms are misused by the authorized persons itself after the license period, so to overcome these defects we are discovering a new system in which we use a biometric system to detect the palm print of the person who owns it. There must be a license period for the fire arms and these license period say for one year is entered in the embedded microprocessor fitted in the firearm. A biometric system is essentially a pattern recognition system that makes use of biometric traits to recognize individuals. Palm is the inner surface of the hand between the wrist and fingers. Palm print is referred to as the principal lines, wrinkles and ridges on the palm. This system proposes Weber’s local descriptors based texture analysis of palm print. The hand palm print image is aligned and cropped according to the key points. The palm print image is enh anced and resized. The features of the palm print are compared with the database image feature vectors using correlation metric. If this module is completed successfully then the person info which contains person authentication number with four digits key will be matched with the extracted data from the already hidden image for second level security.
