Automatic Library Detection

Abstract

The automated, real-time detection of specific blocks of code within a larger body of source code is described. Specific implementations relate to the detection of known code libraries in web page code to improve the efficiency of the generation of polymorphic transformations of the web page code for the purpose of impeding automated cyber-attacks.

What is claimed is: 
     
         1 . A computer-implemented method, comprising:
 receiving source code from a server, the source code being responsive to a request from a client to the server;   using one or more processors, generating a set of tokens based on the source code;   using the one or more processors, generating a first string of values representing a subset of the set of tokens;   using the one or more processors, determining whether any portion of the first string corresponds to any of a plurality of predetermined strings of values, each of the predetermined strings corresponding to a known library;   using the one or more processors, processing the source code responsive to determining whether any portion of the first string corresponds to any of the predetermined strings; and   providing the processed source code to the client in response to the request.
