Intergrity in IT Glossary

a basic security function of cryptography.Integrity provides
verification that the original contents of information have
not been altered or corrupted.without integrity,someone might
alter information or the information might become corrupted,
but the alteration can go undetected.For example,an internet
protocol security property that protect data from unauthorized
modification in transit,ensuring that the data received is exactly
the same as the data sent.Hashfunctions sign each packet with a
crytographic checksum,which the receiving computer checks
before opening the packet.If the packet-and therefore
signature-has changed,the packet is discarded.
