How To Protect Your Computer Data

Everyday a lot of people lose their important data from their computers, and laptops. Mostly, just because they are not aware of the small details, which help to protect it. Let us study, the rise of technology with saving your computer data today.


The Rise of Technology is Significant

Technology is increasing day by day. We are getting immensely involved in the use of computer-based appliances. Moreover, children today are using mobile phones frequently. All your school work, office work and documents are saved into a computer. Which is why it is important to keep your data safe and in a backup form. If data is lost from the computer due to a virus, all your documents are erased and all your work goes in vain. To protect data from getting lost or corrupted there are certain steps which you need to follow.

Install Anti Viruses

Anti-viruses prevent data from getting corrupted viruses such as Trojan horse deletes some of the computer files and data without permission. This is a nuisance and threatens data.


Encryption is the method by which plain text or any other type of data is converted from a readable form to an encoded version that can only be decoded by another entity if they have access to a decryption key. Therefore, encrypt data so that unauthorized people don’t get access to your personal documents.

Create Back Ups

The single most important step in protecting your data from loss is to back it up regularly. How often should you back up? That depends—how much data can you afford to lose if your system crashes completely?

There are numerous ways to back up data:

  • USB
  • SD cards
  • Hard disks
  • Floppy disks
  • Blu ray disks
  • CDs
  • DVDs
  • Cloud storage

Always Use Passwords

Many productivity applications, such as Microsoft Office applications and Adobe Acrobat, will allow you to set passwords on individual documents. To open the document, you must enter the password. Also keeping usernames and passwords can prevent your data from being accessed by unauthorized people.

Secure Wireless Transmissions

Data that you send over a wireless network is even more subject to interception than that sent over an Ethernet network. Hackers don’t need physical access to the network or its devices; anyone with a wireless-enabled portable computer and a high gain antenna can capture data and/or get into the network and access data stored there if the wireless access point isn’t configured securely. You should send or store data only on wireless networks that use encryption, preferably Wi-Fi Protected Access (WPA), which is stronger than Wired Equivalent Protocol (WEP).

Hide Data with Steganography

You can use a steganography program to hide data inside other data. For example, you could hide a text message within a.JPG graphics file or an MP3 music file, or even inside another text file (although the latter is difficult because text files don’t contain many redundant data that can be replaced with the hidden message). Steganography does not encrypt the message, so it’s often used in conjunction with encryption software. The data is encrypted first and then hidden inside another file with the steganography software.

Some steganographic techniques require the exchange of a secret key and others use public/private key cryptography. A popular example of steganography software is Stegomagic, a freeware download that will encrypt messages and hide them in.TXT, .WAV, or.BMP files.
