ABSTRACT

Security has become one of the primary concerns when organizations and institutions like Hotels, Banks, and companies need to be acquainted with the latest developments on security locks. Regardless of the rareness and financial involvements, an increasing number of individuals and cooperate bodies are demanding for better security locks.
Even if an organisation is not security conscious with the introduction of such security system, they will go for one of the latest of these electronic locks.
CHAPTER ONE

INTRODUCTION
Computerized Security Locks
Voice activated, finger prints and infrared lock security is said to be protection against attack from without or subversion from within or afar, it is also precautions taken to keep somebody or something safe from crime, attack, or danger. The source of Texas instruments speaks and spell handheld electronic learning and, introduced in 1978, sparked the present growth of computerized speech, or what is called designated speech synthesis, voice-response systems, in which a computer “speaks” in response to a (non spoken) command, represent a market or under 20 million in 1978. By 1988 that market to estimates by SRI international in manlo park calif. Adding speech recognition, whereby a human voice activates electronic circuits to perform a specific task such as voice activated doors, the market by 1988 is forecast at around 1.3 billion to 1.8 billion, excluding defense and aerospace products.
A number of electronic products that features a computerized speech are already on the consumer market fidelity Electronic Computer chess player, chess challenges, “speaks” with a player; canon inc. and the Panasonic company introduced talking calculators this year; sharp corporation of Japan has digital clock radio that voices the time when a button is pressed. Computerized Security System (CSS) is one of the world’s largest security equipment suppliers and a leader in the electronic access management industry.
Through it’s subsidiaries SAFELOCK and GARD, CSS reaches countless hotels, multifamily properties, commercial facilities, military and government facilities and much more in the production of electronic locks.
Quasar has a talking microwave oven, fisher-price toys an talking dell, taxes instruments a talking language translator, and there are speech-synthesis attachments for personal computers. Prodding the computer-speech industry onward is a host of chip makers who will produce devices inexpensively for anyone able to purchase them in large quantities. The companies include taxes instrument, National Semiconductor Corporation, and the votrax division of federal screw works. Each of the three used a different electronic method to achieve the same and-linear predictive coding, waveform digitalization, and format synthesis. Format synthesis, which uses combined phonemes, the smallest sound units of speech, was also used with the IBM Audio Typing units, designed for the blind, which vocalizes the keypad struck by the user.
Voice recognition was receiving increasing attention too. Heuristic inc, of sunny vale, calif, for example introduced a speech recognition model that enables a hear siegler ADM-3A “dumb terminal” to be voice controlled, through 64-128 speaker-developed words or phrases at a time. The standard recognition accuracy rate is said to be better than 99 percent. Also, IBM researchers have developed a computer to transcribe speck from a 1,000 word vocabulary, printing is automatically with 91 percent accuracy. Malicious hackers are increasingly developing powerful software crime tools. Such as automatic computer virus generators, internet eavesdropping sniffers, passwords guessers, vulnerability testers, and computer service saturators. For example, an internet eavesdropping sniffer intercepts internet messages sent to other computers. A password guesser tries millions of combinations of characters in an effort to guess a computer’s password vulnerability testers look for software weaknesses. These crime tools are also valuable security tools used for testing the security of computers and networks.
An increasingly common hacker tool that has gained widespread public attention is the computer service saturation, used in denial-of-service attacks, which can shut down a selected or targeted computer on the internet by bombarding the computer with more requests than it can handle.
This tools first searches for vulnerable computers on the internet where it can install it’s own software program. Once installed, the compromised computers act like “zombies” sending usage requests to the target computer. If thousands of computers become infected with the software than all would be sending usage requests to the target computer, overwhelming it’s ability to handle the requests for service.

INTRUSION DETECTION SYSTEMS
Security software called intrusion detection systems may be used in computers to detect unusual and suspicious activity and in some cases, stop a variety of harmful actions by authorized persons. Abuse and misuse of sensitive system and application programs and data such as password, inventory, financial, engineering, and personnels files can be detected by this system.

INFRARED ACTIVATED LOCKS (DOORS)
Infrared (IR) lock was developed by SAFELOCK (as security company) to interface with energy management systems. IR provides wireless communications to and from the lock to give you an online lock system without all the hassles of running wires to each lock, there is an IR module in the room and on the lock that communication to a central computer, the central computer reports all keys used in the lock. Below are some of the devices – Electronic Control Unit (ECU) –safes –hospitality an easy-to-use handhold service as a
