As the worlds becomes more advanced each day, it also seems to grow less and less secure. The creation of new virtual venues has also paved the way to the emergence of places where people can be victims of criminal activity such as fraud and identity theft. In the real world, people of high stature get the service of body guards and security forces. Would such protective measures also be beneficial for the world of data?

Most people think that data security is something that only large business entities would have to be concerned about. However, the internet is an open channel can be accessed by anyone. And now that people are doing more personal matters through the internet, such banking shopping, sending confidential male and personal letters, it is probably just right for people to take more steps to keep their privacy and security.

The answer to this situation is file encryption, which is basically a more sophisticated and powerful manifestation of the age-old art of ciphering that has been used by humans throughout history. Do you actually need to take advantage of such programs that make your files secure through complicated encryption? Perhaps knowing more about file encryption would help you decide the right answer to this question.

What exactly is a File Encryption Program?

A file encryption program basically uses complex algorithms to create codes for file contents so that they cannot easily be read by people other than their intended recipients. File encryption programs write messages, files, and other content into codes that can only be deciphered by persons who would have a decoder. It is somewhat similar to the way students write secret messages in class, they use different ways to manipulate messages in such a way that other people would not be able to understand them.

The big difference between the codes that people make and file encryption programs write is the complexity of the encryption being made. While the codes people normally make could take just a few analytical hours or minutes to decipher, the ones made by computers are so complex that they cannot be able to be unraveled by practically anyone even for a lifetime. In fact, even other computers who would not be able to decipher the codes without the right decoder.

The function of file encryption go beyond the field of information technology – computer files and electronic messages, it is also used by other industries such as in the entertainment business. For instance, DVD movies are encrypted so that digital video could not easily be converted into VHS format by consumers. Encryption is also used in to scramble videos of pay-per-view channels and only those who would pay would be given the codes to unscramble the reception.

Perhaps the most important application for file encryption programs is for privacy protection of people and organizations. The most commonly known example is this would be the message encryption being done for confidential electronic messages and projects being sent via the internet. Another example would be the decryption used for telephone conversations and satellite transmissions that help protect the security of concerned parties.

Do you actually need to get a file encryption program?

As mentioned, file encryption has many functions and the need for such security measures depends on the way you use your data and the way you go about your activities in open channels such as the internet. You have to carefully check what exactly you do when you are online.

Do you do banking transactions through the internet, or do you just view websites of your favorite stars? Do you send business messages and projects to your clients and colleagues through email, or do you just send jokes and funny quotes to your friends? Do you shop online and give out your credit card information, or do you just window shop and check out what you can buy in real stores?

When deciding whether you would need file encryption or not, you have to ask yourself if the things you do online actually require you to be secure. If you normally give vital personal information such as your credit card, social security number, addresses, and the like, then you might benefit from buying a file encryption program. But if you do not really do things that could compromise your security then, perhaps getting file encryption would just be a waste of your money.

But still, it never hurts to be safe. If you have extra cash and would like to be sure that you do not fall prey to the many dangers that lurk in technology, then by all means go and get a file encryption program. In these days where the world is becoming more and more complex, one can never be certain of what could happen.

The main reason behind all these compulsions to attain maximum security is confidentiality.  Those documents contain information that is not supposed to be shared to everyone.  You maintain the availability of the information but only to expected audiences.  By also trying to conceal the information from irrelevant people, you ensure that it remains correct and unchanged unless such changes are appropriate and authorized.

Compare such scenario to your computer.  As your computer is very essential in several aspects, it undoubtedly contains a lot of information, whether confidential or for everyone’s consumption.  As owner of the computer, it is simply normal for you to regulate the access to all these important information. 

ACLs or access control lists are usually used to establish control.  ACLs clearly identify who can access a certain file or folder as a whole.  They can indicate who can read or even edit a particular information. 

ACLs may vary from computer to computer.  Various systems mean various types of ACLs as well.  Some have very specific controls while others do not have any at all.  What you can do is to know and maximize the capacity of your computer.

For some computers, the access to information cannot be very limited such as those for online transactions or businesses.  Under these cases, file encryption programs, which involve several mathematical processes, are more appropriate. 

Encryption converts information from a readable one to an encrypted version.  Those who know how to transform them back to their readable form are the only ones who can access the information.

However, the best file encryption programs are those which last for a considerable period of time.  Schemes that are figured out easily after some time are poor ones.  It can be compared to a kid eventually learning more words which allow him to understand what the adults are talking about which he used to not recognize before.  If file encryption programs work this way, they are not, in any way, useful for pc security. 

Whether you use simple ACLs or complicated file encryption programs, you have to remember that your main goal is to give your computer that much-needed security.
