2 Grenzebach Glier & Associates, Inc. Background & Motivation  Getting into the front door of one’s home can present a troublesome situation  Fishing around in pockets for keys  Finding the correct key to unlock the door  Problems arise when it is dark outside  Loss or misplacement of keys  Inconvenient to find keys when hands are tied up

3 Grenzebach Glier & Associates, Inc. Background & Motivation  Various keyless entry systems have been developed  Combination Lock oGain entry into a home by inputting preset code into door keypad

4 Grenzebach Glier & Associates, Inc. Background & Motivation  Remote Door Lock oGain access to home utilizing a small remote device similar to that of a keyless car remote  Electronic Card Key Lock oGain access to home utilizing an electronic card key oElectronic card key must be placed over card reader oDoor unlocks if proper card key is in place oSome locks require sliding of key

5 Grenzebach Glier & Associates, Inc. Background & Motivation  Fingerprint Identification Lock oUser places finger in fingerprint identification scanner oScanner checks for record of the fingerprint oAllows access through door if fingerprint matches records

6 Grenzebach Glier & Associates, Inc. Background & Motivation  All products are great alternatives  Each individual keyless system provides its own unique security protocols  Cost can be a huge downside

7 Grenzebach Glier & Associates, Inc. Background & Motivation  Another alternative to keyless entry systems  Propose a new product designed for residential population  Easy to use, easy to install  Will fit in existing doors in the home  Ability to be upgradeable (i.e. new security features) and expandable (i.e. home automation, lighting controls, temperature controls, etc)  Low power consumption

8 Grenzebach Glier & Associates, Inc. Background & Motivation  What’s the plan?  Homeowner with a special electronic key will be able to access door (discussed in detail later)  Utilize wireless devices that operate on cell, AA, AAA batteries  Wireless device will operate for years without having to constantly change batteries  Wireless devices must be small for easy integration into existing door  User keys must also contain small wireless devices

9 Grenzebach Glier & Associates, Inc. Background & Motivation  Additional features  How to overcome the misplacement or loss of electronic key? oEach key has a unique ID tag oCan set system so that the loss ID tag will not be accepted oIntegrate keyless system with internet Home entry control from remote location

10 Grenzebach Glier & Associates, Inc. Requirements  Phase (1) will involve the interaction of the parts: doorknob, access key, deadbolt and coordinator  Phase (2) will involve interaction between a PC and coordinator of phase (1), and a http web site

11 Grenzebach Glier & Associates, Inc. REQUIREMENTS Phase (1)  Zigbee is used for any wireless interaction  Door unlocks in presence of a valid key when Door Knob is turned  Independent and wireless units run on batteries  Quick system response

12 Grenzebach Glier & Associates, Inc. Requirements (Phase (1))  The key has a practical size  Encryption (AES-128)  Doorknob turning tolerance will be about 20 degrees

13 Grenzebach Glier & Associates, Inc. REQUIREMENTS Phase (2) Phase (1) interfaces with phase (2) The system connects to the internet Access through a http web site User controls the door and checks its status

14 Grenzebach Glier & Associates, Inc. Design Characteristics  Water fall method  Component Based  Design Simplicity  Expandability  User Friendly
