The data protection act becomes very important for those who store sensitive information, on computers. Many of us do not know what happens with our stored data on a day to day basis, or we are unaware of how securely our data is stored. It is common for information to become lost or stolen. Sometimes when information has not been deleted properly, using secure techniques, the data can be recovered by third parties. Lives of those who have had their identity stolen, can become very difficult and hard to cope with. This is what makes it so important, to use the correct methods, to ensure all information that is very personal to people, has been removed and cannot be recovered.
One very strong method of secure data removal is data destruction. Techniques such as melting, crushing and drilling are used to prevent data recovery. These techniques cause complete destruction, which makes it one of the most secure techniques, as people cant put the millions of pieces back together again. However one downfall of this method is the fact that the destroyed devices, can never be re-used as they have been physically broken and destroyed. Mobile data destruction allows a company to hire in another company who specializes in data removal techniques, to physically destroy data on site. The damaged equipment is then recycled. All equipment used should be approved by the government, before it is used. CESG tested equipment is one government approval certificate.
Another data removal method is data sanitizing. Devices such as hard discs, magnetic media and hard drives can all encounter the data sanitizing method, to remove any data within them. This technique offers compete data removal, making it safe to release the equipment into third party hands. Often data cannot be recovered using this technique, as this technique offers a method which no other technique can offer. So if you do not want to destroy your equipment this method is probably one of the best alternatives. Data clearing is a method by which the data is made unreadable to the computer. However special software can be used to recover the data. This being a massive downfall of the technique and therefore should be avoided if the data you are storing, is highly confidential.
On site data destruction methods are available to companies. This causes less hassle to those businesses who require massive amounts of data removal. This method also offers more piece of mind as companies and organizations can see that the information has been destroyed, before being taken away. Any equipment and machinery used by data destruction companies has to be approved by the government first, before any of it can be used. The equipment which has been approved will have been tried and tested, to ensure it is suitable for the job.
Before deciding on which technique is suitable for you, you must consider how sensitive the data is and if recovered and what the consequences may be. As you can see some methods are much more secure than others, therefore the government may require stronger techniques compared to our computers at home.
