Client application fingerprinting based on analysis of client requests

A computer system for generating a fingerprint corresponding to a browser request comprising headers, the computer system comprising:

• a database that stores data that correlates each of a plurality of header types to one of a plurality of values;
• and
• at least one processor configured with instructions to:
• process the headers in the browser request to retrieve a value from the database for each one of the headers in the browser request based on a header type of the header;
• assign a score for the browser request by summing the retrieved values of all of the headers in the browser request;
• generate the fingerprint comprising the score of the browser request;
• analyze the score to determine whether the score falls within at least one predefined numerical range associated with a particular type of client application;
• and
• when the score falls within the at least one predefined numerical range associated with the particular type of client application, identify the particular type of client application associated with the browser request.

A method for generating a fingerprint corresponding to a browser request comprising headers, the method comprising the following operations performed by at least one processor:

• providing a database that stores data that correlates each of a plurality of header types to one of a plurality of values;
• receiving the browser request comprising headers;
• processing the headers in the browser request to retrieve a value from the database for each one of the headers in the browser request based on a header type of the header;
• assigning a score for the browser request by summing the retrieved values of all of the headers in the browser request;
• generating the fingerprint comprising the score of the browser request;
• analyzing the score to determine whether the score falls within at least one predefined numerical range associated with a particular type of client application;
• and
• when the score falls within the at least one predefined numerical range associated with the particular type of client application, identifying the particular type of client application associated with the browser request.

A non-transitory computer-readable medium storing instructions that, when executed, enable one or more processors to:

• provide a database that stores data that correlates each of a plurality of header types to one of a plurality of values;
• process the headers in the browser request to retrieve a value from the database for each one of the headers in the browser request based on a header type of the header;
• assign a score for the browser request by summing the retrieved values of all of the headers in the browser request;
• generate the fingerprint comprising the score of the browser request;
• analyze the score to determine whether the score falls within at least one predefined numerical range associated with a particular type of client application;
• and
• when the score falls within the at least one predefined numerical range associated with the particular type of client application, identify the particular type of client application associated with the browser request.
