I’ve been browsing new stuff from Amazon today and it occurred to me that I’ve done quite a lot of online buying transactions without really being worried about my financial details getting left in the computers I’m using. Granted, I’m only using my home PC and my laptop at times, but I wonder how much stuff gets imprinted on the hard drive of these personal computers that can get decrypted. Not that I think anybody would be willing to waste time to something like that; in MY stuff, I mean. Still, this sort of pushed me to do a little research on Hard Drive Encryption, and I discovered that there are even free encryption software programs available online. Data encryption, apparently, is the process of converting plaintext data into hypertext data, so that they cannot be read, which spells Laptop Security for me. More than just protecting your privacy online, it is also a very important way to shield your personal information like addresses, contact numbers, and, more importantly, credit card details. Some e-mail programs even have encryption systems so that your mails will be protected from third parties who may be intercepting personal mails. I get that sites such as PayPal or other online shopping sites where you input credit card numbers are heavily protected by such Mobile Data Protection System.
