Claim 0:
1. A method implemented by a computing device, the method comprising:
generating application program information, the generating comprising:
encrypting raw application program information using a first auxiliary key;
encrypting the first auxiliary key using a second auxiliary key; and
adding the encrypted first 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;

determining a segmentation number and a plurality of segmentation positions for the application program information, wherein the determining is based on a pre-determined security level of the application program information;
generating an information segmentation algorithm, wherein the information segmentation algorithm comprises the segmentation number and the plurality of segmentation positions;
segmenting the application program information into multiple pieces of program sub-information based on the segmentation number and the plurality of segmentation positions of the information segmentation algorithm, the information segmentation algorithm having undergone algorithm obfuscation processing; and
storing the multiple pieces of program sub-information in a plurality of storage locations of the computing device.
