Data Encryption: How Safe Is Your Data?
These days the safety and security of our data becomes increasingly important. Identity theft is a very real problem. Keeping our personal information is an important step to protect our privacy and ensure that our sensitive data can only be accessed by authorized individuals.
Encryption is a process used with increasing frequency these days and chances are that you send or receive encrypted files frequently, even if you do not realize it. Many email messages are sent in encrypted form as well as financial transactions and some file sharing program.
How Data Encryption Works:
Data encryption is achieved by a process that replaces your information with a code that can only be described if you have the encryption key. The use of the code to hide the meaning of the message has existed since the time of Julius Caesar.
Back in the days of the alphabet keys are used, for example, a letter will be replaced with another. We all have seen the kinds of puzzles in newspapers or magazines.
If you send an email using the encryption process, encryption keys can be included in your email client or as a stand-alone program.
Three Types of Data Encryption
1. Symmetrical Data Encryption
Symmetric encryption of data using file transmission through the programs you use. You must send a decoding key to the receiver separately from your message.
The biggest problem with symmetric encryption is that it’s possible for a hacker to intercept the key to decoding and file during transmission, and thus can read the message.
2. Asymmetric Data Encryption
Asymmetric key encryption involves two separate data decoding, the public key and a private key. This type of data encryption takes longer to transmit, but much safer. When you send a file, you encrypt files using your recipient’s public key. When the recipient receives the file, decodes them using their private key.
3. Data Encryption Software
Data encryption software is a computer program that encrypts a data file or packet of information sent through computer networks. The software uses encryption keys to prevent others from viewing sensitive data.
There are a number of companies that offer data encryption software for personal users. They use one or more of a number of different encryption algorithms to make your data is almost impossible to access without the encryption key.
Data encryption software can be a consideration for you if you run a small business or transferring sensitive information between a group of individuals. There is an encryption program is free software available online as well as more sophisticated programs that can be purchased for a reasonable cost.
E-Commerce: A User’s Key
E-commerce is one of the main users of the software to encrypt the data. Encryption is not only the protection of personal financial information, ensuring that both merchants and customers dealing with the same people they hope will be dealing with and not with third parties such as hackers or cyber criminals.
It also prevents rejection, which means that it keeps a record of where the message was sent and received, so no one can claim that they do not accept or act on a particular message
