An identity information verification method comprising: receiving image information sent by a client terminal and rendered by the client terminal; extracting characteristic information from the image information, the characteristic information comprising shape characteristic information, the shape characteristic information being represented by an outer boundary of an object within the image information or an outer boundary of an image associated with the image information; matching the characteristic information with pre-collected characteristic judgment information, the characteristic judgment information having associated identity information and the characteristic judgment information comprising shape characteristic judgment information; and judging, when the matching succeeds, that the client terminal fits the identity information, wherein the step of matching the characteristic information with pre-collected characteristic judgment information comprises: calculating a similarity degree between the characteristic information and the pre-collected characteristic judgment information by calculating a similarity degree between the shape characteristic information and the corresponding shape characteristic judgment information; and judging whether the similarity degree is greater than a preset similarity degree threshold; if yes, judging that the matching between the characteristic information and the pre-collected characteristic judgment information succeeds; or if no, judging that the matching between the characteristic information and the pre-collected characteristic judgment information fails. receiving image information sent by a client terminal and rendered by the client terminal; extracting characteristic information from the image information, the characteristic information comprising shape characteristic information, the shape characteristic information being represented by an outer boundary of an object within the image information or an outer boundary of an image associated with the image information; matching the characteristic information with pre-collected characteristic judgment information, the characteristic judgment information having associated identity information and the characteristic judgment information comprising shape characteristic judgment information; and judging, when the matching succeeds, that the client terminal fits the identity information, wherein the step of matching the characteristic information with pre-collected characteristic judgment information comprises: calculating a similarity degree between the characteristic information and the pre-collected characteristic judgment information by calculating a similarity degree between the shape characteristic information and the corresponding shape characteristic judgment information; and judging whether the similarity degree is greater than a preset similarity degree threshold; if yes, judging that the matching between the characteristic information and the pre-collected characteristic judgment information succeeds; or if no, judging that the matching between the characteristic information and the pre-collected characteristic judgment information fails. calculating a similarity degree between the characteristic information and the pre-collected characteristic judgment information by calculating a similarity degree between the shape characteristic information and the corresponding shape characteristic judgment information; and judging whether the similarity degree is greater than a preset similarity degree threshold; if yes, judging that the matching between the characteristic information and the pre-collected characteristic judgment information succeeds; or if no, judging that the matching between the characteristic information and the pre-collected characteristic judgment information fails. if yes, judging that the matching between the characteristic information and the pre-collected characteristic judgment information succeeds; or if no, judging that the matching between the characteristic information and the pre-collected characteristic judgment information fails.
