Quick response (QR) codes have recently become a popular data container for optical encryption systems. Their effectiveness is based on the error-correction codes, that allow them to decode data even when the media itself is significantly damaged. However, QR codes were developed for specific applications and have a significant number of elements that are superfluous for optical encryption. In this paper we present a new customizable digital data container (CDDC), designed to replace QR codes in optical encryption. CDDC is based on the error-correction codes too, but has a wide range of configurable parameters and can be specialized for a particular optical setup. The results of noise robustness analysis, numerical and optical experiments on application of the new container in a spatially incoherent optical encryption system demonstrate the supremacy of CDDC in comparison to QR codes in terms of error correction capabilities and data density.

快速响应 (QR) 码最近已成为光学加密系统的流行数据容器。它们的有效性基于纠错码，即使在媒体本身受到严重损坏时，它们也可以解码数据。但是，QR 码是为特定应用而开发的，并且具有大量对于光学加密来说是多余的元素。在本文中，我们提出了一种新的可定制数字数据容器 (CDDC)，旨在取代光学加密中的二维码。CDDC 也基于纠错码，但具有广泛的可配置参数，并且可以专门用于特定的光学设置。噪声鲁棒性分析结果，
