An Example of the Use of A Biometric System and the Implications

British Broadcasting Corporation also known as the BBC is an organisation which uses blogs. For many categories and some of the employees, they have blogs in which they discuss topics related to them. For instance there is the Scottish Symphony Orchestra Blog where they discuss updates on events e.t.c.

The benefits of having the blogs in an organisation such as this is that people are updated on the subjects that relate to them. For example if an individual is interested in the Scottish Symphony Orchestra, then he or she can just go into that blog and will be find information related to the orchestra only. Therefore, information is interesting and precise.

A disadvantages of having a blog in an organisation is if an employee somehow gets the freedom of placing anything on his or her blog, it could become a disastrous for the company if that person does not keep it professional. Bloggers may have biased opinions which could lead to followers disliking someone in the company. This could bring the organisation down.

The Disadvantages of Organisations Using Biometric Devices.

Despite the benefits biometric devices bring to an organisation, it also has costs.

• For industries that deal with chemicals, the employees' fingerprints are affected by the chemicals. Therefore, it will not be ideal to implement the usage of fingerprint recognition in these organisations.
• The biometric system is very expensive to try and implement and it may not be all firms that will be able to afford it to protect the data they have.
• With the eye recognition security system it can be ineffective over time as people with serious heatlh such as diabetes may have their eyes changing. With voice authentication, as we grow older, when we have a flu or cold our voice changes, or in a noisy environment it is not effective. So it cannot be used in every organisation.
• A biometric device that captures the iris of an individual may be very difficult to use as the iris can be covered by eyelashes, eyelids and even the images reflected from the cornea.
• It can also be a health hazard specifically for the fingerprint authentication system or the vein system. This is because there sensors will be touched by many people which will increase the risk of health problems.
• People are also worried about the privacy concerns of criminal implications.

The Advantages of Organisations Using Biometric Devices.

Biometric devises are to make life easier for others to access important information but in a very cautious way. With the biometric system the person is the key, the password to access the data. We dont need to have use passwords which can be forgotten or lost.

For organisations it is very useful for it uses the uniqueness of each individual to lock or activate access confidential information. In hospitals or clinics, private information can be accessed by more than one pĥysician as they use the same room and computerrs. the biometric system not only ensure more security but simplifies the procedures required to access the information- the individual does not have to remember a code or password to type in. It is also user friendly as one just has to use his or her body part rather than using your family history information.

The person that needs to access that information has to be present. An individuals body part like the voice, vein, fingerprint, eye are very difficult to copy, change, loose, ciculate and steal. This means the private data that the institution has will be very difficult for an unauthorised person to access.

What the Biometric Devices Replaces or Can Replacing.

The biometric technology such as voiceprint recognition tool is made to replace hand geometry readers or keys. As our voices are really unique due to the shape of our vocal cavities and the way we move our mouths. Thus, it is not easy for someone to access information they are not supposed to. It has been made to ensure more security.

Rather than using passwords (which if someone gets a hold off can easily gain access to data), voice recognition systems are used. This ensures that it is the person that is authorised that gains access through the IT system.

A multi-biometric system however, combines several unibiometric methods together making it more effective. For example if a person had an unfortunate accident and his or her finger got chopped off, then person could then use their voice or face recognition as a means to be be identified and to be allowed access.

Fingerprint recognition for instance is one biometric method which is very significant and useful. It is a very cheap method to utilise. It is now been implemented on laptops which is will eventually replace using the 'CTRL+ATL+DELETE' logging system. This is known as the fingerprint password manager. This is a much better system as finger prints are unique individual on Earth it is almost impossible to replicate and passwords on the other hand can be forgotten, misplaced or easily retrieved.

Biometric Devices

A biometric device is an information technology device that recognises a person based on physical characteristics such as fingerprints,face, retina patterns, irises or veins,wieght and behavioural charcateristics through voice recognition, handwriting or typing rhythm e.t.c.

Biometric devices are use 3 steps which are enrollment, storage and comparison.
Enrollment is when one uses the boimetric device for the first time and his or her information is recorded such as his or her name and ID number. A physical traist is then recorded.
With storage, the whole information retrieved is not saved but instead analysed and then translated into a graph or code. And comparison is when the system measures up the information it has stored with that of which is been presented. And then the biometric device then decides to either accept or reject the individual claiming to be the person of the stored information.
