Integrity

No Hacking

This is where measures are taken that are intended to allow the recipient to determine that the information it receives has not been altered in transit or by anyone or process other than the originator. Integrity schemes often use some of the same underlying technologies as confidentiality schemes, but usually involve adding additional information in the form of packets, to a communication to form the basis of an algorithmic check rather than the encoding all of the communication. When sending files over the internet using one of these schemes, the document will be broken up into many pieces and all will be sent different routs to the reciever. These packets tell the recieving computer if the ammount of data in the packet has changed or if any of the packets have been lost along the way that create a document during communication.
