An Identity Card is any document which may be used to verify aspects of an identity. If issued in the form of a small, mostly standard-sized card, it is usually called an Identity Card (IC). It plays in the society, threats of fraud, tampering, and identity theft arises. Thus, security and authenticity of these ID cards and their owners prove to be of much necessity. This paper goal is to make use of Visual Cryptography and 2D data matrix codes to address these issues. Visual Cryptography is a secret sharing scheme where a confidential image is encrypted into noise-like secure shares, which can be reconstructed visually by superimposing the shares.
