Data encryption, protection, and anticounterfeiting are crucial in the modern information society. Though a number of technologies have been developed, data security is still facing severe challenges. Herein, a fundamental new approach capable of multilevel data encryption, protection, and anticounterfeiting is developed based on the responsive zwitterionic polymers named as poly(pentafluorophenyl acrylate)-co-poly[(3-((3-acrylamidopropyl)dimethylammonio)propane-1-sulfonate)] (pPFPA-co-pADPS). Detailed studies reveal that zwitterionic polymers exhibit drastic electrical property changes to humidity variation. By reliance of this feature, highly secure touchless palm-based biometric authentication is realized; further, field-effect transistors (FETs) using zwitterionic polymers as dielectrics show nonvolatile memory behaviors with good reliability and rewrite-ability. Remarkably, not only appropriate voltages but also specific humidity range are required to safely decrypt the stored message. In addition, the memory gains the ability to destroy the stored data under counterfeiting/hacking condition, thus preventing the data from being stolen by repeated trials. Therefore, a high level of data security is realized. This work provides new insights into zwitterionic copolymer dielectric based OFETs, demonstrates the first example of double-stage data encryption and protection by OFET memory, and opens up new opportunities for data-securing by responsive materials.

具有湿度和电压双开关功能的两性离子响应聚合物，用于多层数据加密和防伪

数据加密，保护和防伪在现代信息社会中至关重要。尽管已经开发了许多技术，但是数据安全性仍然面临严峻挑战。在此，基于称为聚（五氟苯基丙烯酸酯）-共聚[（3-（（3-丙烯酰胺基丙基）二甲基氨）丙烷-1]的响应性两性离子聚合物，开发了一种能够进行多级数据加密，保护和防伪的基本新方法。-磺酸盐]]（pPFPA- co-pADPS）。详细的研究表明，两性离子聚合物对湿度变化表现出剧烈的电性能变化。依靠此功能，可以实现高度安全的非接触式基于手掌的生物特征认证。此外，使用两性离子聚合物作为电介质的场效应晶体管（FET）具有非易失性存储行为，具有良好的可靠性和可重写性。值得注意的是，不仅需要适当的电压，而且需要特定的湿度范围才能安全地解密所存储的消息。另外，存储器具有在伪造/黑客攻击条件下销毁存储的数据的能力，从而防止了数据因反复试验而被盗。因此，实现了高水平的数据安全性。这项工作为基于两性离子共聚物电介质的OFET提供了新的见解，
