In this work, we reported a multi-responsive luminescent hydrogel with properties of encryption, naked eye sensing of glucose, shape memory, self-healing, and antibacterial activity. The hydrogel (GA/
CCS
/DNSA/Eu
3+
) was obtained by mixing phenylboronic acid-modified gelatin (GA-DBA), catechol-modified carboxymethyl chitosan (

PCA
), 3,5-dinitrosalicylic acid (DNSA), and Eu
3+
ions through a facile heating-cooling process. The resultant hydrogel exhibits reversible luminescence and color and phase changes in response to temperature, acid/base, salt, and redox stimuli. Based on the multiple responsiveness, information encryption and decryption, naked eye sensing of glucose, remarkable shape memory, and enhanced mechanical properties of the as-prepared hydrogel were realized. In addition, the self-healing capacity was also achieved due to the dynamic bonds in GA/

hydrogels. Specifically, the GA/
CCS
/DNSA/Eu
3+
hydrogels possess antibacterial activity owing to the bacteriostasis of the

complex. Thus, GA/

hydrogels have potential applications in the fields of anticounterfeiting, wearable devices, biomedicine, sensing, etc.
