A system for the secure storage and transmission of data utilizes a visual algorithm to encode sensitive data in a secure manner onto a data card or other storage device. Whether a photograph or other image, data representing pixels are encoded by scrambling them one color at a time, with scrambling instructions being encoded in the pixels themselves. A character assigned to each color is used for additional verification of the authorization during decoding. In a preferred embodiment, the time of encoding is the basis for the characters assigned to respective colors.
