Social aspect information acquisition method and system based on image robust steganography

The invention discloses a social aspect information collection method and system based on image robust steganography, and the method comprises the steps: collecting an original image from a collection end; embedding the secret information into the original image to obtain a secret-carrying image; the secret-carrying graph is transmitted to the verification end by the acquisition end; extracting secret information from the secret-carrying graph; and according to the extracted secret information, judging whether an original image corresponding to the secret-carrying image is an image collected by a specified collection end or not. According to the technical scheme, the image provider can be prevented from counterfeiting the image, and the authenticity of the acquired image is improved. 本发明公开一种基于图像鲁棒隐写的社会面信息采集方法及系统，方法包括，自采集端采集原始图像；将秘密信息嵌入原始图像中，得到载密图；载密图由采集端传输至验证端；自载密图中提取秘密信息；根据提取的所述秘密信息判断该载密图对应的原始图像是否为指定采集端采集的图像。此种技术方案能够防止图像提供方伪造图像，提高采集图像的真实性。
