Abstract
Presented herein are systems and methods for checking the integrity of data transmissions between or within one or more digital processing systems by identifying a data characteristic that is likely to change if there is an error in transmission. According to one embodiment, data messages are modified to achieve a selected characteristic according to a predetermined protocol, and changes to the data are recorded in a longitudinal check code (LCC) word, which is used by the receiver to decode the data message and restore the original data.

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