Bawa continued: "On the Stouffer's portfolio we have also improved the nutritionals so that a significant number of our recipes now have the Health Check symbol
(Heart and Stroke Foundation).
The brand's packaging now includes call-outs with key nutritional information, the American Heart Association heart check symbol
and graphic elements that imply movement and activity.
(iii) One side only sends few of check symbols of the data rather than the whole data to the other side; this will be enough for the other side to eliminate the data difference and then conclude the key.
The IJS algorithm adopted by  was used to generate check symbols. One of its shortages must be pointed out here.
t means how many check symbols are exchanged for the data reconciliation between two data sets.
Other algorithms may also be used to generate the check symbols, if they are proved to have high efficiency, for example, Reed-Solomon Encoding.
The voter should check symbols
printed on the ballot paper and stamp the symbol allotted to the candidates of his or her choice contesting elections.
The following requirements are established for WSN correction codes: low complexity of coding/decoding; low hardware requirements for algorithm implementation (microcontroller speed, memory capacity); adaptive change of check symbols number according to channel parameters.
But there is a problem of changing (increasing/ decreasing) the check symbols number in those codes.
Otherwise, there is a problem of efficient maintaining of check symbols. Therefore authors proposed modified correction codes based on RNS and described below.
