Security Methods & Biometrics

Security Methods & Biometrics

1. The recognition of an individual by an unique physiological or behavioural characteristic.

2. Can be used to control the access to a computer system or a location.

3. Palm Print Recognition

   • Key in your idenity number, place your plam ibnot the device. The system checks the palm and matches the user's identity number and authorises entry. The door will then inlock and let the person through, if the user id not identitfied the door will stay locked.

4. Fingerprint

   • The user places their index finger on the reader sensor, the computer automatically permits access if their is a match between the scanner and a fingerprint image on the computer system.

5. Iris Scanning

   • A camera looks at the iris of a perosn it sends a copy to the computer system that compares the image to other images on the database. if there is a match authorised access is permitted.

6. Speaker Recognition

   • It is where the speaker is identified by a voice pattern. It doesn't recognise what id being said though.

7. ADVANTAGES

   • It is unique to each individual so it is more reliable than trdational methods.
   • It identifiers a user physical characteristice so they can't be lost or copied by anyone else.
   • No password/username/access code to be remembered.
   • mobile devcies can run and application to use the camera as an input device for facial recognistion purposes.

8. DISADVANTAGES

   • Many individuals are concered about allowing the use of their boimetric characteristic for privacy reasons.
   • Some biometric readers are 100% reliable - few cases of false acceptance.
   • Certain biometric techniques are affected by ambient conditions - the speaker recognition can be affected by the background noise.

9. Physical Security Methods

   • Security Guards
     • Control the access to the buildings and log visits of potential intruders.
     • Can check the ID cards of those hospital staff needing to work in a particular secure area.
   • Security Cameras
     • monitor an area and the video footage can be viewed later.
   • Backup Tapes and Disks

10. Software Security Methods

    • Virus protection
