1. A method for checking the integrity of data transmission, the method comprising:

  • breaking, by a transmitter apparatus, a data message into a plurality of n-bit words;

    grouping the n-bit words into word groups of (n−

    m) n-bit words (where 0<

    m<

    n);

    conditionally modifying the n-bit words to have a selected characteristic;

    generating a longitudinal check code (LCC) word for a respective word group, which records characteristics of the n-bit words of the word group; and

    adding the LCC word to the respective word group, resulting in word groups of (n−

    m+1) words, whereby the n-bit words of the word groups of (n−

    m+1) words may be analyzed together with the LCC word to check the integrity of the data transmission, and to restore the data message.
