Privacy is necessary for human society to function. The problem is not that the information exists but that it reaches the wrong people. Information on the internet could bring great benefits to society, and to individuals, when huge data-sets can be refined to yield information otherwise unavailable. But once the information is gathered, a precautionary principle has to apply.
Information security is provided on computers and over the Internet by a variety of methods. A simple but straightforward security method is to only keep sensitive information on removable storage media like portable flash memory drives or external hard drives. But the most popular forms of security all rely on encryption, the process of encoding information in such a way that only the person or computer with the key can decode it.
What is Encryption?
Encryption secures online information, protects the data from countless daily attacks and is a vital component of our national defences. Encryption is a fundamental aspect of Information Security practice in order to protect sensitive data through protocols such as PKI, SSH, SSL and other digital signatures and certificates.
Encryption process:
Encryption is the process of translating plain text data ‘plaintext’ into something that appears to be random and meaningless ‘ciphertext’. Decryption is the process of converting ciphertext back to plaintext.
To encrypt more than a small amount of data, symmetric encryption is used. A symmetric key is used during both the encryption and decryption processes. To decrypt a particular piece of ciphertext, the key that was used to encrypt the data must be used.

When it comes to our collective sense of internet privacy, we are the real people should work on improving security where we are most vulnerable on our own devices.
ReplyDeleteInternet users like you and me should know how to protect our privacy. There are many to do it and we need to gain the knowledge and accessibility on what is t he best to tool to do so. Without protecting our privacy, others may take advantages of us.
