Abstract

An engraved solid piece carries data comprising specific information on a surface of the engraved solid piece. The surface is covered by a plurality of block structures, comprising at least a first block structure. Each block structure is a spatially restricted collection of modulated features and base features, which are spread over the surface of the engraved solid piece. Each modulated feature and each base feature has respectively a three-dimensional modulated-feature profile and a three-dimensional base-feature profile. Each of the modulated-feature profiles is the result of applying a corresponding modulation to one of the three-dimensional base-feature profiles, according to a specific, corresponding information. Each modulated feature further is a symbol, which is a transcription of a character of an alphabet. The alphabet is a collection of characters, which are distinct objects of well-defined elementary data. Each of the base features is an engraved elementary three-dimensional topographical element of the surface. Each of the modulated features is an engraved three-dimensional topographical element of the surface. At least a part of the data is transcribed by a code-block structure of modulated features, the code-block structure thereby constituting at least a part of a block structure corresponding to the at least one part of the data. The modulated features of the first block structure are arranged according to a first ordered map, the first ordered map comprising at least a first finite ordered set of first positions of the modulated features of a first code-block structure on the surface, the first block structure corresponding to a first part of the data, and the first ordered map further is configured to arrange the modulated features of the first block structure to constitute an aesthetic ensemble on the surface and render the respective symbols corresponding to the modulated features of the first code-block structure imperceptible to the human eye, but retrievable by means of a software-driven image-sensor/processor combination.
