Security Methods In Hospitals

1. Biometrics

   • Biometrics: the recogniction of an individuals unique physiological or behavioural characteristics.
   • Types of Biometrics
     • Iris Scanning
       • The user will look at a camera that will capture an image of their iris. The computer will compare that with the database and match it (If possible).
         • Facial Recognition Works in a similar way.
     • Fingerprint Recognition
       • The user will place their finger onto a scanner and the divice will then scan the fingerpring pattern and match it to a database. This will then (If matched up) willow the user to access the device.
     • Speech Recognition
       • The user will speak into a devive which will compare the speach patern to a database attempting to match it up with a existing record.
     • Palm Print Recognition
       • Similar to finger print a device matches the palms indivdual features and vein patterns in a hand and matches this to a database
   • Advantages and Disadvantages
     • Advantages
       • The biometric identification is unique to the ndividual to each user and so can not be coppied
       • A password or security question does not need to be remembered so it is unlikely that the user will forget.
       • The method is more reliable than that of others.
       • Mobile divices can also use this type of security software.
     • Disadvantages
       • Some individuals are concerned about using biometrics for privecy reasons.
       • They are not 100% reliable and in some cases there are false rejection
       • Some biometrics can be affected by the environment such as speech recognition can be affected by background noise.

2. Physical security methods

   • Types of Physical security
     • Security Camera
       • Guards can moniter these with a live colour and sound feed and scan for threats and /or danger.
     • Keycards/Number locks
       • Key cards can be used to activate magnetic lock a simple way to enter/exit a room with out the need to remember a code. These can be easy to lose or be stolen though.
       • Number locks are similar to a key card appart from they use a code to allow users to gain access to a specific area.
     • Security guards
       • Used to control access to the building and logs visitors. They can also check the ID card of staff to make sure they are permitted into a specific area.
     • Backup Tapes and Disks
       • In the event of lost data a back up will be taken reguraly to ensure that n the event of a disaster they have a back up in a seperater area.

3. Software security

   • Types of software security.
     • User acccess permissions
       • A admin will set a user to be allowed to access specific areas and files withing the area to stop un necessasr information eaching them.
     • User asccess passwords
       • Each user will set a password for their area and files so that people can not gain access to that area.
     • Fire wall/ Intrusion Detection System
       • Hacking and access of malicious software will be stopped at this point and some files will require admin permissions to access them.
     • Encryption
       • Files and other details will be transfered into a code (e.g. a=e f=$ g=%) to make it difficult for hackers to understand the data they try to access.
     • Virus Protection
       • Virus portection software will warn the user when a virus is potentiol and automaticall clean any malicious software.
     • Data back up and recovery
       • In the event of lost data a back up will be taken reguraly to ensure that n the event of a disaster they have a back up in a seperater area.
