The utility model provides a self-adhesive label with a waterproof function, and relates to the field of seed seedling raising, the self-adhesive label comprises an outer frame, a bottom film, an adhesive layer, a base body, a coating, a covering film and a protective film, the protective film is arranged above the covering film and the outer frame and used for improving the protective performance above the outer frame and the covering film, the base body can support the coating, and the adhesive layer is arranged on the base body. Commodity information can be printed on the surface of the coating, the propaganda ability of the self-adhesive label can be improved, the upper surface of the coating can be protected through the covering film, the covering film is made of a high-transparency wear-resistant material, the information on the surface of the coating cannot be affected, meanwhile, the safety of the information on the surface of the coating is improved, water and fire damage is reduced, and the service life is prolonged. Through protection of the base film and the protective film, the base body and the coating can be protected, safety in the transportation process is improved, the base body and the coating can be protected through the covering film in the using process, abrasion resistance and safety are improved, and the service life is prolonged.

This application provides a method, apparatus, device, and storage medium for self-destruction of NOR flash chip data, applied in the field of non-volatile memory device technology. By configuring a mode status bit in the volatile status register of the non-volatile memory device, and based on the actual destruction mode indicated by the mode status bit, upon receiving a self-destruct trigger command, data erasure operations are preferentially performed on a predefined priority destruction area. Subsequently, an erasure control signal is generated for the remaining areas for subsequent erasure. After all erasure operations are completed, the non-volatile memory device is placed in a shielded and locked state. In this state, the read interface responds to read requests by outputting preset mask data, and the device is prohibited from executing the normal boot process. This method has the advantage of preventing any form of data recovery and chip reuse, greatly improving the data security of the NOR flash chip and effectively resisting the risks of physical attacks and information leakage.
