“…Typically, single-base representation is used to code databases. ese bases are adenine (A), thymine (T), cytosine (C), guanine (G), isoleucine (I), phenylalanine (F), serine (S), glutamine (Q), histidine (H), asparagine (N), aspartic acid (D), arginine (R), glutamic acid(E), lysine (K), leucine (L), valine (V), tryptophan (W), tyrosine (Y), methionine (M), and proline (P) [21,22]. In this paper, the bases of protein motifs will be used to hide data in specified bits of binary representation of a base.…”
