Feb20 comment Matrix multiplied by mod p ok got it. thanks. Feb20 accepted Matrix multiplied by mod p Feb20 asked Matrix multiplied by mod p Feb18 accepted What does it mean to multiply a matrix by $\bmod{p}$ Feb18 comment What does it mean to multiply a matrix by $\bmod{p}$ are you saying taht I must simply divide each element of Matrix B by p and put the remainder in the place ? Feb18 comment What does it mean to multiply a matrix by $\bmod{p}$ In your illustration, what is the value of b in mod b Feb18 comment What does it mean to multiply a matrix by $\bmod{p}$ Sorry, I did not understand your illustration. Are you saying that if I want to calculate 21(mod 5), I must subtract 5 from 21 five times ? Is 21(mod 5) = 1 ? Similarly is 48 (mod 2) =44 ?

Thanks. Jan6 revised Can a matrix based “secret sharing scheme” be applied to image based secret sharing? added 84 characters in body; edited title Jan6 comment Can a matrix based “secret sharing scheme” be applied to image based secret sharing? Actually, if you go thru the link, what they are suggesting is to take a matrix, and split it into n no. of parts(using their algorithm) which become the "shares". Now the holders of these "shares" can come together to "merge" the shares to regain the original secret(matrix). Thus effective "secret-sharing" Jan6 asked Can a matrix based “secret sharing scheme” be applied to image based secret sharing? Oct21 comment Does Pi contain all possible number combinations? Also, "Joy" occurs thrice, and "sad" a whopping 11 times ! I guess the universe is trying to tell us something ! Oct21 comment Does Pi contain all possible number combinations?
