We introduce for the first time the concept of an information "container" before a standard optical encrypting procedure. The "container" selected is a QR code which offers the main advantage of being tolerant to pollutant speckle noise. Besides, the QR code can be read by smartphones, a massively used device. Additionally, QR code includes another secure step to the encrypting benefits the optical methods provide. The QR is generated by means of worldwide free available software. The concept development probes that speckle noise polluting the outcomes of normal optical encrypting procedures can be avoided, then making more attractive the adoption of these techniques. Actual smartphone collected results are shown to validate our proposal.
我们首次在标准光学加密程序之前引入了信息“容器”的概念。所选择的“容器”是一个二维码，它具有容忍污染物散斑噪声的主要优点。此外，二维码可以被智能手机读取，而智能手机是一种广泛使用的设备。此外，二维码为光学方法提供的加密优势增加了另一个安全步骤。二维码是通过全球免费可用的软件生成的。概念开发表明，可以避免散斑噪声污染正常光学加密程序的结果，从而使这些技术的应用更具吸引力。展示了实际智能手机收集的结果以验证我们的提议。
