Abstract: Smart phones have been extensively used with a huge array of sensitive and private information 
stored on these devices. To secure such data from being leaked, user authentication schemes are 
essential. Current password/pattern-based user authentication schemes are susceptible to shoulder 
surfing attacks and distort attacks. Biometric authentication techniques are safer as compared 
to secret word recognition for authentication intention. Biometric techniques use 
certain characteristics of human to authenticate the legitimate user.  
We here present a novel approach to unbreakable authentication for smart phones with flexible 
combinations of multiple multimedia features, screen angles and shaking directions. We can take 
advantage of the multi-touch surface to combine or frame the sequence of biometric finger prints 
techniques with the help of 1 to 10 fingers, shaking handsets, images, texts, audio, videos, PINs 
etc. We defined a comprehensive set of multimedia and screen angles and shaking directions 
with the types order (type number) and overall order of the keys.  
As a result of robust login enhancements, it is good to enhance authentication further by 
considering entire set of keys which is set of multimedia's, angles of the mobiles, and shakings 
with the order of types(type number) and sequencing to login into the smart phones. Hence, it is 
fairly good, robust and unbreakable approach to protect device from unauthorized sequence of 
keys inputs like Image, Text, video , audio etc., and deny for unauthorized attempts in any 
missing/altered sequence of inputs. This will give a robust security of authentication for our daily 
devices against misuse in the future cracks!
BRIEF DESCRIPTIONS OF DRAWINGS 
The detailed description is set forth with reference to the accompanying figure. Figure 1 illustrates the 
functionality of smart phones when accessed by the user with proper sequence of Authentication Keys (Criteria set 
at configurations) for a login v/s login failure due to altered/missing sequence of all usable keys or Types. Figure 2 
shows the example of Login Failed due to altered / Missing sequence of Authentication Keys(Criteria set at 
configurations) and success of logins with exact order of TYPES/Sequences , etc.
