A security device comprises a substrate having a transparent region (1). At least one optical element (2, 3) is provided in part of the transparent region, the optical element causing an incident off-axis light beam transmitted through the optical element to be redirected away from a line parallel with the incident light beam whereby when the device is viewed in transmission directly against a backlight, the presence of the optical element cannot be discerned but when the device is moved relative to the backlight such that lines of sight from the viewer to the transparent region and from the transparent region to the backlight form an obtuse angle (a) at which redirected light is visible to the viewer, a contrast is viewed between the part of the transparent region including the optical element and another part of the transparent region. When the security device is viewed in reflection under diffuse lighting conditions either no contrast can be discerned between the two parts or a different contrast can be discerned between the two parts.

The invention discloses an anti-fake method with digital information and relates to the field of an anti-fake method.

The invention relates to a computer random color graphics anti-counterfeiting method. A digital anti-counterfeiting technology and a variable printing technology are organically combined. Codes generated according to a system key are multidigit characters or Chinese characters, the codes generated by the system are redefined to obtain a pattern by using a digital printer, the characters are given color logical labels, and thus each code represents a specified and colorful pattern, wherein the codes generated by the system are signs, ACSII (American Standard Code for Information Interchange) codes, Chinese characters, English letters, digits or operational symbols, and the pattern shape presented on an anti-counterfeiting product is the pattern obtained by redefining the codes generated by the system or a combination of the pattern and color. The duplication of anti-counterfeiting codes is prevented, the uniqueness of each code is guaranteed, and thus the security of the anti-counterfeiting product is guaranteed. A consumer can verify the anti-counterfeiting product through various information channels. Because pattern information also has diversified colors, counterfeiting becomes more difficult.
