Encoding information in digital polymers has become a promising approach for data storage in recent years. High-level information security is crucial for practical application, which is still challenging in digital polymers due to the lack of efficient techniques. Herein, we proposed a cascaded encryption/decryption approach that uses Morse-coded digital polymers to encipher sequence information as well as molecular weight distribution (MWD) information. The MWD information could be deconvoluted in size exclusion chromatography (1st decryption), whereas the 2nd decryption was performed in tandem mass spectrometry. The correct information could only be accessed after two successive decryption processes, thus providing high-level information security. Furthermore, this cascaded strategy was applied to a printing ink formulation for multidimensional anti-counterfeiting applications toward high-value artwork.
