Methods for constructing, generating, and reading a dot-matrix code, dot-matrix code generating and reading terminals, and a dot-matrix code system. The method for constructing a dot-matrix code includes: constructing a plurality of information units arranged in an N×N matrix; configuring the plurality of information units as information unit modules and/or marker unit modules; storing, in each of the information unit modules, a value based on a relative position of the information point within the corresponding information unit module; signaling identification information of the dot-matrix code through an arrangement of a subset of the information points, wherein the subset of the information points are contained in the marker unit modules. The methods for constructing, generating, and reading a dot-matrix code, the dot-matrix code generating and reading terminals, and the dot-matrix code system of the present disclosure can provide uniformly distributed dot-matrix codes with information hiding features, satisfying practical needs.
