Paper Abstract

This paper presents a new approach, called smartID, for the protection of travel documents. We introduce a specific signature format exploiting as much as possible the given modulus size for generating a digital signature with a partial message recovery feature. This specific formatted digital signature enables a very efficient representation of the authenticity information of the travel document. It is show that the complete whole content of a travel document page, i.e. the image information and the text information, can be securely stored with a RSA modulus size of up to 6144 bits in a single PDF417 2D barcode which is quite limited in its total capacity. The approach supports the Kerckhoff principle, the authenticity of the data, and the authenticity of the issuing authority that generated the data. The approach neither depends on a specific data carrier nor on the specific cryptographic public key system.
