Software forensics is the science of analyzing software source code or binary code to determine whether intellectual property infringement or theft occurred. It is the centerpiece of lawsuits, trials, and settlements when companies are in dispute over issues involving software patents, copyrights, and trade secrets. Software forensics tools can compare code to determine correlation, a measure that can be used to guide a software forensics expert.

Past methods of software forensics

edit

Past methods of code comparison included hashing [1], statistical analysis [2], text matching [3], and tokenization [4]. These methods compared software code and produced a single measure indicating whether copying had occurred. However, these measures were not accurate enough to be admissible in court because the results were not accurate, the algorithms could be easily fooled by simple substitutions in the code, and the methods did not take into account that fact that code could be similar for reasons other than copying.

Robert Zeidman

edit

In 2003, Robert Zeidman developed algorithms, which he incorporated in the CodeSuite tool, for multidimensional software correlation that divides software code into basic elements and determines which elements are similar, or “correlated.” He also created a procedure for filtering and interpreting the correlations to eliminate reasons for correlation that are not due to copying: common algorithms, third-party code, common identifier names, common author, and automatic code generation. The combination of these algorithms and procedures resulted in a more reliable and quantitative analysis than was available previously. Zeidman’s book, "The Software IP Detective's Handbook," is considered the standard textbook for software forensics[1][2] and the CodeSuite tools and methodology has been used in many software IP litigations including ConnectU v. Facebook, Symantec v. IRS [5], and SCO Group, Inc. v. International Business Machines Corp.

edit

Following the use of software tools to compare code to determine the amount of correlation, an expert can use an iterative filtering process to determine that the correlated code is due to third-party code, code generation tools, commonly used names, common algorithms, common programmers, or copying. If the correlation is due to copying, and the copier did not have the authority from the rights holder, then copyright infringement occurred.

Trade secret protection and infringement

edit

Software can contain trade secrets, which provide a competitive advantage to a business. To determine trade secret theft, the same tools and processes can be used to detect copyright infringement. If code was copied without authority, and that code has the characteristics of a trade secret—it is not generally known, the business keeps it secret, and its secrecy maintains its value to the business—then the copied code constitutes trade secret theft.

Trade secret theft can also involve the taking of code functionality without literally copying the code. Comparing code functionality is a very difficult problem that has yet to be accomplished by any algorithm in reasonable time. For this reason, finding the theft of code functionality is still mostly a manual process.

Patent infringement

edit

As with trade secret functionality, it is not currently possible to scientifically detect software patent infringement, as software patents cover general implementation rather than specific source code. For example, a program that implements a patented invention can be written in many available programming languages, using different function names and variable names and performing operations in different sequences. There are so many combinations of ways to implement inventions in software that even the most powerful modern computers cannot consider all combinations of code that might infringe a patent. This work is still left to human experts using their knowledge and experience, but it is a problem that many in software forensics are trying to automate by finding an algorithm or simplifying process.

Objective facts before subjective evidence

edit

One important rule of any forensic analysis is that the objective facts must be considered first. Reviewing comments in the code or searching the Internet to find information about the companies that distribute the code and the programmers who wrote the code are useful only after the objective facts regarding correlation have been considered. Once an analysis has been performed using forensic tools and procedures, analysts can then begin looking at subjective evidence like comments in the code. If the information in that subjective evidence conflicts with the objective analysis, analysts need to doubt the subjective evidence. Fake copyright notices, open source notifications, or programmer names that were added to source code after copying took place, in order to disguise the copying, are not uncommon in real-world cases of code theft.

Robert “Bob” Zeidman (born January 18, 1960) is an American electrical engineer, educator and inventor who has made contributions in Application Specific Integrated Circuit (ASIC) design, Field Programmable Gate Array (FPGA) design, embedded systems development, software synthesis, software analysis and software forensics. Best known as the inventor of software forensics,[3][4] Zeidman’s pioneering research and development of software-forensics tools was instrumental in making detection of software source-code correlation practical and accurate, and in turning previously subjective information into empirical evidence. He has personally consulted on more than 160 court cases involving billions of dollars in disputed intellectual property, the software forensics tools he developed have been used in litigation worldwide, and his book, "The Software IP Detective's Handbook," is considered the standard textbook for software forensics.[5][6]

Zeidman is also well known for his work developing embedded systems. Since 1987, Zeidman has designed ASICs, FPGAs, and PC boards for RISC-based parallel processor systems, vector supercomputers, laser printers, hardware emulators, network switches and routers, and various real-time systems. His clients have included Apple Computer, Cadence Design Systems, Cisco Systems, Intel, Mentor Graphics, Ricoh Systems, and Texas Instruments.[7]

Zeidman received a master's degree in electrical engineering from Stanford University, and bachelor's degrees in electrical engineering and physics from Cornell University. He holds 22 granted patents and four pending patents.[8][9]

Zeidman founded many companies, seven of which are still operating under his leadership: Z Enterprises (novelty items from Silicon Valley; May 1986 – present);[10] Zeidman Consulting (hardware and software design services; October 1987 – present);[11] eVault Remote Backup Service (January 1992 – April 1999); The Chalkboard Network (online business and engineering courses; January 1999 – December 2002); Zeidman Technologies (software tools for embedded software development; December 2002 – present);[12] Software Analysis and Forensic Engineering Corporation (software tools for intellectual property litigation; September 2007 – present);[13] SamAnna Designs (fashion accessories; January 2011 – present);[14] Swiss Creek Publications (independent publisher; June 2012 – present);[15] Firtiva (online videos and films; December 2013 – present).[16]

Zeidman has written many technical papers on hardware and software design methods, and has taught courses on Verilog, ASIC, and FPGA design at engineering conferences throughout the world. He is the author of five engineering books: “Verilog Designer's Library,”[17] “Introduction to Verilog,”[18] “Designing with FPGAs and CPLDs,”[19] “The Software IP Detective's Handbook,”[20] and “Just Enough Electronics to Impress Your Friends and Colleagues.”[21] He is the co-author of two engineering books: “Circuit Design: Know it All (Newnes Know it All)”[22] and “FPGAs: World Class Designs.”[23] He is also the author of three novels: “The Amazing Adventure of Edward and Dr. Sprechtmachen”,[24] “Horror Flick,”[25] and “Good Intentions.”[26]

Zeidman is a senior member of the IEEE and was the recipient of the 1994 Wyle/EE Times American by Design Award, the 2003 Jolt Reader's Choice Award, the 2010 and the 2015 Outstanding Engineer Award from the IEEE Santa Clara Valley Section[27] and from the Region 6 Central Area[28] for his pioneering contributions to the field of software forensics.
