Classification: CPC G | IPC G

Claim 11:
12. An apparatus comprising:
one or more processors; and
one or more memories storing thereon computer-readable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:
obtaining an information segmentation algorithm, wherein the information segmentation algorithm comprises a segmentation number and a plurality of segmentation positions determined for application program information to be obtained based on a pre-determined security level of the application program information;
performing deobfuscation on the information segmentation algorithm having undergone algorithm obfuscation processing;
extracting multiple pieces of program sub-information from a plurality of storage locations of a computing device; and
recombining the multiple pieces of program sub-information based at least in part on the segmentation number and the plurality of segmentation positions of the information segmentation algorithm having undergone the deobfuscation to obtain application program information, wherein the application program information is generated by:
encrypting raw application program information using a first auxiliary key;
encrypting the first auxiliary key using a second auxiliary key; and
adding the encrypted key auxiliary key and attribute information of the raw application program information to the encrypted raw application program information to generate the application program information, the attribute information comprising a length and a type of the raw application program information.
