Two-thirds of the worldâs population â over 4.5 billion people â have bad bacteria known as H. Pylori living in their stomach. This harmful bacteria can be a major source of fatigue. Your stomachâs inner lining produces acid to digest food, while simultaneously creating protective mucus to guard from this acid.
DEFINITION of 'Encryption'. Encryption is a means of securing data using a password (key). The encryption process is simple â data is secured by translating information using an algorithm and a binary key. When the data needs to be read back, the code is decrypted using either the same key or a different key depending on the type of encryption used.
History of encryption. The word encryption comes from the Greek word kryptos, meaning hidden or secret. The use of encryption is nearly as old as the art of communication itself. As early as 1900 BC, an Egyptian scribe used non-standard hieroglyphs to hide the meaning of an inscription.
