Abstract: Systems, methods, and articles are disclosed for encoding data using imperfect patterns formed from graphic elements arranged on a surface. A data record is encoded through controlled variations in the graphic elements relative to a common layout such that the data record is redundantly represented and recoverable from observation of a portion of the pattern. Images of the pattern may be processed to extract and verify the data record under viewing conditions including partial occlusion, distortion, or noise. In some embodiments, decoding outputs include confidence or consistency assessments, identification of image regions contributing to decoding, or visual augmentation to guide user interaction. The techniques support robust machine-readable encoding while preserving aesthetic flexibility for applications including authentication, inventory tracking, and user interfaces. Other embodiments may be disclosed and/or claimed.

Abstract: Embodiments of the invention include ascribing a predetermined data record to a physical surface in the form of an imperfect aesthetic pattern of marks. An image showing a portion of the surface, when processed with a decoder, yields the predetermined, verified data record.
