The invention discloses a security control system applied to a mobile terminal. A main board of the mobile terminal is provided with a security chip. The system comprises a chip driving module which is connected with the security chip and is used for driving the security chip to generate security keys, and types of the security keys at least comprise an asymmetric key, a transmission key and a work key; a key management module which is connected with the chip driving module and is used for driving the chip driving module to employ the key type corresponding to the data information according to the content of the data information for encryption and decryption processing on the data information; and a security control module which is connected with the key management module and is used for sending a control instruction to the key management module for encryption processing on the data information, and the control instruction is used for controlling the key management module. The system solves technical problems of poor data security and easy tampering caused by only soft encryption processing on the data existing in a mobile terminal in the prior art.

The invention provides a script encryption method, a script decryption method and an engine. The script encryption method comprises the following steps: acquiring an original script to be encrypted, wherein the original script comprises first data required to be encrypted; acquiring a symbol string corresponding to the first data according to the data type of the first data and the mapping relation between pre-configured reference data and the symbol string, wherein the reference data are data which belong to the first data type determined according to the weak type characteristic of a scripting language used by the original script and can be directly mapped to the symbol string; and replacing the first data with the symbol string corresponding to the first data, so as to obtain an encrypted script. According to the technical scheme of the invention, the original script is encrypted with the symbol string, so that the encrypted script looks like a messy code and is difficult to decrypt. Therefore, the security of scripts can be improved.

The invention discloses the preparation and application of photonic crystal materials with responsive invisible patterns, and belongs to the technical field of nanometer materials and functional polymer materials. The invention uses polystyrene microspheres as templates to prepare hollow silica photonic crystals, and then selectively constructs regions with different hydrophilicity and hydrophobicity on the hollow silica photonic crystals through Michael addition reaction to form regions that can selectively respond to water vapor. invisible pattern. The modified hollow silica photonic crystal material with invisible patterns prepared by the invention can be used for moisture detection and other solvent detection. Under the action of dynamic moisture, obvious patterns of different colors can be displayed within 1 second, and its It has long-term stability and high responsiveness, and there is no obvious error after 100 repetitions. The method provided by the invention has good application prospects in the fields of preparation of polystyrene microspheres, hollow silica microspheres and photonic crystals thereof, patterned preparation, detection of various solvents and their vapors, and the like.

The invention discloses an encryption method of biological features, an encryption matching method and an encryption system, and an encryption matching system. The encryption method comprises the following steps: respectively computing similarity and / or difference of a to be identified biological feature with each feature base in N feature base spaces to obtain a corresponding data set, thereby realizing the encryption on the biological feature; respectively computing the similarity and / or the difference of two to be identified biological features with each feature base in the feature base space, comparing the computing result in the one-to-one correspondence, thereby realizing the matching of two to be identified biological features. The to be identified biological feature is converted into a group of abstract code data, the group of code data supports the one-way encrypted storage, the matching of the biological feature based on the code data or the cipher text is realized, the requirement of the clear text of the biological feature is avoided, and the security of the biological feature on the identification is guaranteed.

The invention provides an encryption method, an application lock and an electronic device, which receive an unlocking password input by a user, and when the unlocking password input by the user is the same as the preset unlocking password, start the application lock and display a file selection interface to be encrypted; Through the file selection interface to be encrypted, determine the file to be encrypted; migrate the file to be encrypted from the original storage path to the preset private storage space, so that the application that stores the file to be encrypted does not need to be encrypted as a whole, but will need to be encrypted The files are migrated from the original storage path to the preset private storage space, thus achieving the purpose of encrypting one or more files individually.
