Show that if longitudinal parity is used as an error detection code, values in a database can still be modified without detection. (Longitudinal parity is computed for the n-th bit of each byte; that is, one parity bit is computed and retained for all bits in the 0th position, another parity bit for all bits in the 1st position, etc.)
What will be an ideal response?
Interchange of bytes is not detected with longitudinal parity.
