These attacks are intended to either avoid the security  afforded by the system or to put off the normal functioning of the system.  The old ink and paper method which is grossly susceptible to wear and  tear makes it very vulnerable. Proper use of cryptography hash functions  greatly reduces the risks in automated biometric systems as hackers  have to find both secret key and template. It is evidenced that still fraud  goes on to some extent. Here in this paper a new idea is presented to  make system more secure by use of encryption and its HMAC code.  Here the secret key (which is in the form of pixel intensities) will be  merged in the picture itself while encoding and its unique corresponding  HMAC code generated, and at decoding end only the authentic user will  be allowed to decode and digitally encrypted hashed image is stored in  the database for future references and usages.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783846544655\"\u003e\u003ch3\u003efor Authenticating and Validating Biometrics Information\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783846544655","offer_id":39471367225437,"sku":"9783846544655","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/16d6245c-18ef-4292-83f4-05cffbcc1dc5.jpg?v=1768976491","url":"https:\/\/shop.autorenwelt.de\/en\/products\/a-hybrid-hash-message-authentication-code-hmac-von-enangha-abeng","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
