“…We used the voltage-on/off operation controlled by a programmable and web-enabled control system to change information, based on the color definition shown in Figure C (green as 0, ivory as 1, brown as 2, and yellow as 3), and thus realizing modern anticounterfeiting in optical labels. Because the system we designed has the ability to realize information interaction with the external world through circuits and electrical signals, it shows potential to interact in different parts of the supply chain, such as manufacturing, transportation, sales, and consumption. , All information could be uploaded to the cloud platform, stored, and used for authenticity verification in the next link, as well as further changed via the internet, making the system blockchain-like to track information and show potential for broader application scenarios. ,, …”

Nations, industries, and aspects of everyday life have undergone forgery and counterfeiting ever since the emergence of commercialization. Securing documents and products with anticounterfeit additives shows promise for authentication, allowing one to combat ever-increasing global counterfeiting. One most-used effective encryption strategy is to combine with optical-security markers on the required protection objects; however, state-of-the-art labels still suffer from imitation due to their poor complexity and easy forecasting, as a result of deterministic production. Developing advanced anticounterfeiting tags with unusual optical characters and further incorporating complex security features are desired to achieve multimodal, unbreakable authentication capacity; unfortunately, this has not yet been achieved. Here, we prepare a series of stable circularly polarized luminescence (CPL) materials, composed of toxicity-free, high-quality-emitting inorganic quantum dots (QDs) and liquid crystals, using a designed helical-coassembly strategy. This CPL system achieves a figure of merit (FM, assessing the performance of both luminescence dissymmetry and quantum yield) value of 0.39, fulfilling practical demands for anticounterfeiting applications. Based on these CPL structures, we produce a type of multimodal-responsive security materials (MRSMs) that exhibits six different stimuli-responsive modes, including light activation, polarization, temperature, voltage, pressure, and view angle. Thus, we show a proof-of-principle blockchain-like integrated anticounterfeiting system, allowing multimodal-responsive, interactive/changeable information encryption–decryption. We further encapsulate the obtained security materials into a fiber to expand our materials to work on flexible fabrics, that is, building an intelligent textile with a color-adaptable function along with environmental change.

“…Furthermore, the development of wearable smart devices will increase the chance to integrate Raman readers into smart glasses and wrist bands. Meanwhile, advanced techniques such as cloud storage, big‐data science, artificial intelligence, [ 100 ] and the Internet of Things, might all play some essential roles in the further development of SERS‐based anti‐counterfeit labels. In this case, these SERS labels will have even broader applications in various scenarios of anti‐counterfeiting.…”

“…For example, in a 10 by 10 label with two choices of Ramanactive probe molecules, and each type of molecule has three differentiable concentration variables, the possible molecular combination is 3 2 , and the encoding capacity is 9 100 or about 10 95 . This equation is ideal, while in actual cases, a researcher needs to consider the error that could occur when differentiating the spectra of two kinds of molecular combinations or from two pixels.…”

Anti‐counterfeit labels protect many commercial goods, drugs, and currencies from counterfeiting activities. Recently, the designs of anti‐counterfeit labels have emerged utilizing surface‐enhanced Raman scattering (SERS) as a powerful technique, in which SERS‐active materials provide strong Raman signals of probe molecules. These signals are unique and, so far, have rarely been used in practical anti‐counterfeit labels applications. In this review, the general methodology of using Raman and SERS in designing anti‐counterfeit labels is first introduced. Then, two types of secret information in SERS labels, spectroscopic information and graphical information, are detailed and discussed with a focus on how the molecular information is encoded with SERS labels. Later, several advanced SERS labels are presented which combine existing security features such as barcode, quick response code, fluorescence, and unclonable features. Finally, the challenges in building usable SERS anti‐counterfeit labels are discussed and possible research directions are described.

“…[8] This kind of encryption can hardly be decrypted due to its high complexity and switchable ability, which will contribute to a senior security level. [12][13][14][15][16] ErOCl thin flakes can be obtained by mechanical exfoliation process (Figure S1c, Supporting Information). As shown in Figure S1d, Supporting Information, the thinnest thickness of the obtained flake is ≈3.7 nm.…”

High‐security encryption has always been important in economic and military fields as well as in daily life. 2D van der Waals (vdW) rare‐earth (RE) materials have advantages in photoluminescence (PL) modulation to achieve high‐security encryption because of their multiple sharp emission peaks, which will facilitate the multimode regulation for high‐security encryption of programmable information. Here, programmable information encryption has been achieved by applying 2D vdW ErOCl via the editable electric‐tunable PL. The correct information encoded in PL outputs can be tactfully decrypted from the PL intensity ratio of 2H11/2–4I15/2 and 4S3/2–4I15/2 transitions. This strategy for ASCII codes and images encryption with high‐security is demonstrated. This novel approach, PL modulation of 2D vdW RE material based on programmable electric inputs, will mark a new path to achieve high‐security encryption.
