| titleOfInvention | Method and device for feature extraction |
| abstract | Disclosed are a method and device for feature extraction. The method comprises: acquiring a batch of black sample files and white sample files from an application layer of a smart terminal operating system; parsing each file, acquiring information structures of all functions contained in each cell, and computing a checksum for each function; determining whether or not the files contain respective functions corresponding to respective checksums, thus compiling statistics on the number of occurrences of each function in the black sample files and in the white sample files; and, extracting a black sample feature on the basis of functions occurring only in the black sample files and not occurring in the white sample files, or extracting a white sample feature on a similar basis. This shows that per the present invention, by analysis and computation of acquired white sample files and black sample files, compiled are statistics on the number of occurrences of the checksum of each function in the files, and finally, the functions occurring only in the black sample files and not occurring in the white sample files serve as a basis for black sample feature extraction. |
