Don't Steal My Information!
By Jeff
It's important to take the precautions to protect you and your products from information theft these days, because it's getting easier and easier for people to share digital products. Information theft is a type of security risk and it's defined as stealing an individual's personal or confidential information. When this is stolen this can cause as much damage, or possibly more then hardware or software theft. Business or home users are both at risk of information theft.
One example is a malicious individual stealing credit cards so they can make unauthorized purchases on another person's account. If information is transmitted over a network then it has a very high chance for malicious users to intercept the information. Every in the path of your data can see what you send, and they can also see what you send. A lot of companies try to stop information from being stolen by applying some user identification and authentication controls. These constraints are best for protecting computers along a company's premise. However, to protect information on the Internet and on networks, companies use a handful of encryption methods. Encryption refers to the process of converting data into an unreadable form. One type of encryption software is Obfuscated code which is a programming language that is extremely hard to read. Encrypted data is like any other data because you can send it through a lot of options, but to read it you must decrypt or decipher it into a more readable form. Throughout the encryption process, the unencrypted data or input is known as plaintext and the encrypted data, or output is known as ciphertext. To encrypt information, the programmer converts the plaintext into ciphertext using some type of encryption key. An encryption key is the programmed formula that the person who receives the data uses to decrypt the ciphertext. There are a variety of encryption or algorithm methods. However, with an encryption key formula, you will be using more then one of these techniques.
Some business use available software, while others develop their own. When an individual send information online such as through an email for example, they will never know who might intercept it, or to whom it could possibly be forwarded to. That's why it's not such a good idea to send confidential information online. However, an individual can help protect themselves by encrypting the information, or signing it digitally. Some very popular email encryption software is known as Pretty Good Piracy (PGP) and Centurion Soft Secure Protection. Pretty Good Piracy is known as freeware, which means that individuals can use it for their personal needs but not for commercial purposes. You can download this for no cost.
A digital signature is a type of encrypted code that an individual, website, or company pastes to an electronic document to make sure that the individual is who they claim to be. The code will most likely consist of the user name and a hash of usually part of the message. A hash is a type of mathematical formula that generates content from a specific message, so it is different from a message. The recipient will have to generate a new hash from the received message and compares it from the one with the digital signature to make sure that they match appropriately. The main
