Types and models of Access Control System, aryah.net

Aryah.net is committed to provide the best ACCESS CONTROL SYSTEM.

In recent times, there are large numbers of Biometric Systems that are commercially available. Such Biometric systems are based on unique characteristics of human being. The most common, reliable and successful system is the one based on Finger Prints. Users are supposed to put their thumb/index finger (or any specified finger) in the finger reader. The system then compares the finger print that is read with that in the central database for authentication.

Most of the Biometric Systems do not keep an image of the fingerprint but a template. A template is basically a number that is calculated based on various characteristics of the fingerprint. Such an approach is desirable so that unauthorized persons may not sneak in unauthorized images of finger print in the database. When a Finger print is to be matched, it’s ‘template’ number is computed and compared with that stored in the database. Most systems allow for dry, greasy, chaffed and minor cuts on the fingers. The other biometric systems are based on ‘Retina of the eye’, Palm, photograph or voice pattern recognition. The Palm based systems take the image of the palm from various angles and compare the same. The system that is based on Finger Prints is most popular and economical.

PROXIMITY ACCESS CONTROL SYSTEM

The core of Proximity system is the Proximity Reader and Proximity Card. There are two types of readers in the market – One that has an inbuilt controller with capability to authorize access with or without being connected to a PC. The other kind requires a PC to be connected at all times.

Depending upon the configuration of the premises, one or more readers may be used. If more than one reader is used then it is called a Networked system, which is usually connected to a PC. Some systems use a 8 core or a 16 core wire for connecting all the Readers while some systems use only 2 core wire, thereby reducing the cost of wiring and maintenance.

The better systems have readers that can be used interchangeably in a standalone or a networked configuration. Also, some systems have bulky controllers attached to the readers that require a separate source of power as well as add to the cost. The current day readers have built-in controllers and can be directly connected to a PC.

Another use of Proximity systems is to record attendance for employees. For recording attendance, minimum two readers are required – one for IN and one for OUT. The employees are supposed to show their cards to the appropriate Reader upon arrival or exit. These transactions of IN and OUT are recorded in the attached PC. From the PC various reports can be printed.

Most of the Access control systems come with readymade attendance software as an option.

The advanced Proximity Based systems come with inbuilt Password Based system too. It is possible to specify if the employees can enter using Password alone or Proximity Card alone or both are required. Such an option gives additional flexibility to define the Access Policy for the organization.

PC BASED ACCESS CONTROL SYSTEM

The systems currently being offered in the market come in with variety of features to cater to different types of requirements. Along with the basic security functions of validating and controlling access, the PC based systems offer optional features like Time and Attendance, MIS Reporting etc., providing the management with a lot of value- added benefits. Some of the most useful features include:

Multiple entrance/exit monitoring. The capacities ranging from a few users to hundreds of users – easily configurable for organization of any size.

The system can interface with the personnel information files that may be there already in a computerized environment. This makes the installation quick and reduces the data-entry errors.

Flexible Time zones – highly useful for controlling entry / exit as per shift timings; basically, the PC based systems offer the possibility of programming the rules of entrance and exit.

PC based systems are very user friendly and offer unmatched flexibility in setting up various parameters.

PC based systems also keep the record of the transactions on the hard disk for extended periods of time.
User selectable personal identification numbers – provides additional security.

GENERAL FEATURES

security products system working in home, aryah.net

Home security products give a homeowner peace of mind as well as the ability to protect loved ones and physical possessions around-the-clock.

Having the right security products installed in a home can ward off home invasion, theft and injury. Home security products should be concealed somewhat and not out in the open for invaders to see.
Products that protect one's home should also be linked to the local police department so that they can be notified in the event of an emergency or break-in.
Security products are used for monitoring the home in the perimeter of the property surrounding the home. Products are designed to alert the homeowner when invasion is taking place or someone is lurking around the property line.
Most systems are electronic or battery powered and some are hooked up to cables and satellites to keep a close watch on property parameters.
There are four main types of home security products. The first type is home entry and invasion protection--used for setting up a high tech alarm system that can be digitally programmed and customized to the homeowners needs. An alarm system goes off if someone unwelcome enters through a door or window, and some systems even tell the intruder to leave, and then alert the homeowner and even the police.
The second is window and door alerts, helpful in alerting the homeowner as to who is coming in and out of the house and certain rooms in the home.
The third are motion sensors, which keep the outside of the home protected by signaling when intruders have set off a sensor, making a light come on or signaling a sound when someone crosses over the driveway. The fourth is a combination of security gates, cameras connected to a DVR, bars for windows and doors as well as sliding door locks.
One should consider the expense of installing a complete security system. The homeowner can install individual security products based on the needs of the home and family to save money. Not all security products work together, but they must be linked electronically to get full protection.
Preventing theft can save thousands of dollars if the home was broken into and items were stolen. Having home security products installed can also reduce car and auto insurance premiums.

6 tips on choosing the right security products, aryah.net

Finding the right security products to protect an organization’s IT investments is often a difficult, time-consuming task. With so many offerings on the market, how does an organization know which product best meets its needs? Which product actually delivers on its claims?\

One way companies can accomplish this more easily – and save time and resources – is to rely on third parties to provide independent product assurance as part of the request-for-proposal process.

Carefully document product-selection requirements and then formally compare them with either published testing results or certification requirements from a third-party assurance program. Requiring potential products to be tested or externally certified significantly reduces time spent analyzing products.

Several entities – including independent testing and certification labs, government assurance programs, trade magazines, analyst firms and commercial labs – offer varying levels of product assurance. Independent testing and certification labs offer a cost-effective choice. Additionally, the best third-party test labs strive to be unbiased and vendor- and product-neutral.

Not all testing organizations are the same. Pay close attention to the organization’s public criteria (testing/certification criteria should be publicly available); relevance (how much overlap exists between the third party’s published criteria and the enterprise’s business requirements); and frequency (how often is testing done and at what intervals). Also, ensure that the testing organization relies on a scientific, repeatable testing methodology.

Choose a third-party organization that requires its certified products to pass all – not just some – of its tests and verifies that fixes are incorporated into the product. Product assurance testing should not be a static, once-and-done process. Rather, look for ongoing testing.

How do biometric system Work? By aryah.net

The term biometrics refers to techniques used to recognize individuals by analyzing their physical and behavioral traits. They are used to boost the level of security and access for information technology. The techniques are split into two categories — physiological and behavioral.

Aryah.net is the best in selling all types of biometric system Products.

The physiological category is based on the body and its shapes and patterns, including fingerprints, palm design, face recognition and eye recognition. Behavioral biometrics is based on personal behaviors, including vocal recognition and typing.

Physiological biometrics work by analyzing and storing the physical trait to be used for security. Biometrics creates an algorithm, a numeric encryption of the stored trait. The algorithm holds the minute details of the physical trait and looks for matches when the biometric security system is activated.

For example, if it’s a retina scan, the biometric system stores the length of connective tissue, rings in the eye and the optical corona. When someone passes through the biometrics, a scanner will “read” the eye and then look for matches against the stored algorithm.

Behavioral biometrics looks for traits of behavior such as voice patterns, hand signatures or typing rhythms. Behavioral biometrics records these traits similar as its physiological counterpart. However, it requires regular updates due to the regular shifts in behavioral traits.

Biometrics works by checking users against a database (a collection of records) of recorded traits. When a user requests verification, the computer holding the database reads the user’s traits and compares them. If authorization does not pass, the user is rejected. If authorization passes, the user is then allowed to access the computer or room that was protected.

Biometrics is considered good systems of security. However, the technology is not perfect. It suffers from False Acceptances or False Rejections. A False Acceptance is when an individual is allowed passed the system although they are not a registered user.

This could occur when a person is similar to a user or has copied the user’s biological or behavioral information. A False Rejection occurs when a registered user is falsely rejected and not allowed access. This occurs when a user’s criteria does not match their stored information. For example, a cold could alter a vocal pattern or pitch.

Biometrics is often used in conjunction with other security systems to resolve rates of False Acceptances and False Rejections.

Passwords, Smart Cards and Token Generators can allow for additional levels of quality assurance. If a false user can get past the biometrics, they may be prompted for a password or smart card which they may not possess. If a registered user is rejected, they may be prompted for a smart card or password, allowing them another chance to enter the system.

Using tips for a Fingerprint Scanner, aryah.net

A fingerprint scanner is used to match the biometrics of a person with an identification mark, their fingerprint. Fingerprints are completely unique to each individual and no two are alike. This uniqueness makes fingerprint scanning excellent for security and identification purposes.

Purchase a fingerprint scanner. They are small enough today that they can be attached to a laptop computer for mobile uses if necessary. They are available in either single-finger scanners, where you can do one finger at a time, or whole-hand scanners.

Install any necessary software to use the scanner.

Set up the location where you will use the fingerprint scanner. Depending on the application (police station, high security room in a building, children’s safety program) this can be either a fixed location or mobile.

Place the required number of fingers onto the scanning plate. The scanner will use either light photons or an analog electrical signal to take the fingerprint “picture.” This will depend on what type of scanner you are using.
