Examples of mostly behavioral characteristics include gait a person's manner of walking or voice. Facial recognition is the use of the unique configuration of a person's facial features to accurately identify them, usually from surveillance video.

There may be fences to avoid circumventing this access control. An alternative of access control in the strict sense physically controlling access itself is a system of checking authorized presence, see e.
A variant is exit control, e. Physical access control can be achieved by a human a guard, bouncer, or receptionistthrough mechanical means such as locks and keys, or through technological means such as access control systems like the mantrap.
Within these environments, physical key management may also be employed as a means of further managing and monitoring access to mechanically keyed areas or access to certain small assets. An access control system determines who is allowed to enter or exit, where they are allowed to exit or enter, and when they are allowed to enter or exit.
Historically, this was partially accomplished through keys and locks. When a door is locked, only someone with a key can enter through the door, depending on how the lock is configured. Mechanical locks and keys do not allow restriction of the key holder to specific times or dates.
Mechanical locks and keys do not provide records of the key used on any specific door, and the keys can be easily copied or transferred to an unauthorized person.
When a mechanical key is lost or the key holder is no longer authorized to use the protected area, the locks must be re-keyed. A wide range of credentials can be used to replace mechanical keys. The electronic access control system grants access based on the credential presented.
When access is granted, the door is unlocked for a predetermined time and the transaction is recorded. When access is refused, the door remains locked and the attempted access is recorded. The system will also monitor the door and alarm if the door is forced open or held open too long after being unlocked.
The control panel compares the credential's number to an access control list, grants or denies the presented request, and sends a transaction log to a database.
When access is denied based on the access control listthe door remains locked.
If there is a match between the credential and the access control list, the control panel operates a relay that in turn unlocks the door. The control panel also ignores a door open signal to prevent an alarm. Often the reader provides feedback, such as a flashing red LED for an access denied and a flashing green LED for an access granted.
Credentials can be passed around, thus subverting the access control list. For example, Alice has access rights to the server roombut Bob does not. Alice either gives Bob her credential, or Bob takes it; he now has access to the server room. To prevent this, two-factor authentication can be used.
In a two factor transaction, the presented credential and a second factor are needed for access to be granted; another factor can be a PIN, a second credential, operator intervention, or a biometric input.
In addition, a fourth factor of authentication is now recognized: For example, a user may have their password, but have forgotten their smart card. In such a scenario, if the user is known to designated cohorts, the cohorts may provide their smart card and password, in combination with the extant factor of the user in question, and thus provide two factors for the user with the missing credential, giving three factors overall to allow access.
Typically, credentials can be something a person knows such as a number or PINsomething they have such as an access badgesomething they are such as a biometric featureor some combination of these items. This is known as multi-factor authentication. The typical credential is an access card or key-fob, and newer software can also turn users' smartphones into access devices.
Also available are key-fobs, which are more compact than ID cards, and attach to a key ring. Biometric technologies include fingerprint, facial recognition, iris recognition, retinal scan, voice, and hand geometry. The built-in biometric technologies found on newer smartphones can also be used as credentials in conjunction with access software running on mobile devices.
Typically, the access point is a door. An electronic access control door can contain several elements.To aid the reader, the paper is structured in three discrete sections: the conceptualisation of event tourism and then progress in the research literature and then a model of the event tourism system: We commence the first section by discussing the epistemology and ontology of event tourism to outline some of the key propositions around events tourism so as to highlights it significance to.
The vast majority of computer surveillance involves the monitoring of data and traffic on the Internet. In the United States for example, under the Communications Assistance For Law Enforcement Act, all phone calls and broadband Internet traffic (emails, web traffic, instant messaging, etc.) are required to be available for unimpeded real-time monitoring by federal law enforcement agencies.
