The Safest Key-Smart Key

摘要: Crime inhibits the development of a society. Preventive measures taken at right time can prevent theft and burglary from victimizing civilians. This paper presents simple, embedded, low cost solution to domestic security that is intuitive, economic implementable. The proposed model incorporates two layers security. One biometric finger print recognition other password consisting preset number pulsed vibrations only be felt. key strong established by random delays between successive vibrations. Successive authentications lack pattern, as they happen in time, leaving observers clueless. We call this Smart Key. Key does not require significant maintenance powered its own embedded DC UPS. In way, it removes any requirements such an external UPS/Inverter which expensive. data less design Keys make them universal identical, frees user distress case lost. system very modular welcomes expansion functionality with ease. It has regulated variable power supply port for additional peripherals, making stand-alone reliable system.
