Speckle visual password information hiding method, system and equipment and storage medium

The invention discloses a speckle visual password information hiding method, system and device and a storage medium, and relates to the field of information hiding, and the method comprises the steps: obtaining a watermark image, a natural speckle image and a threshold parameter; respectively segmenting the watermark image and the natural speckle image to obtain a watermark image sequence and a natural speckle image sequence; traversing the watermark image sequence and the natural speckle image sequence, and generating random speckle elements according to the watermark image sequence, the natural speckle image sequence and the threshold parameter by using an improved gray reordering algorithm; converting the random speckle element into a random speckle image; the random speckle image comprises the hidden watermark image. According to the invention, the security of secret sharing can be improved. 本发明公开一种散斑视觉密码信息隐藏方法、系统、设备及存储介质，涉及信息隐藏领域，方法包括获取水印图像、自然散斑图像和阈值参数；分别对所述水印图像和所述自然散斑图像进行分割，得到水印图像序列和自然散斑图像序列；遍历所述水印图像序列和
