Definitions
- Another way to combat software theft is to try to identify the source of the stolen software using watermarks. This involves applying unique watermarks to each copy of the software so that when a stolen piece of software is found, the watermark in the stolen software will corresponding to one of the unique watermarks in the authorized software. This requires modification of the computer code, which is undesirable. Further, this technique can be overcome by removing the watermark from the stolen software or removing the watermark from the authorized software so that all further copies do not contain the unique watermark.
- Exemplary embodiments of the present invention are directed to techniques for combating software theft by identifying whether at least a portion of one piece of software appears in another piece of software.
- the present invention allows the identification of whether portions of one piece of software appear in a different piece of software, even when the overall operation of the two pieces of software is different.
- the inventive technique is particularly useful because it operates using compiled computer binaries, and thus does not require access to the underlying source code.
- fingerprints are generated using compiled computer binaries and the fingerprints are compared to determine whether there are sufficient similarities so as to indicate theft of at least a portion of one of the compiled computer binaries in the other compiled computer binary.
- the fingerprints are generated by disassembling the compiled computer binaries and generating a control flow graph and function call graphs for each function in the control flow graph. Each function is then processed to identify unique spectra. These unique spectra are used to identify similarities between the different compiled computer binaries.

- Figure 3 is a flow diagram of an exemplary process for generating a fingerprint using binary code in accordance with the present invention
- FIG. 4 is a block diagram of an exemplary call graph in accordance with the present invention.

- Figures 7A and 7B are flow diagrams of an exemplary process for matching fingerprints in accordance with the present invention.
- FIG. 1 is a flow diagram of the overall process of exemplary embodiments of the present invention.
- the overall process involves generating a fingerprint from compiled computer binaries (step 300) and matching the generated fingerprints to determine whether there is sufficient similarity (step 700).
- fingerprint generation from compiled computer binaries that are later compared for matching can be performed at approximately the same time or can be performed at different times. For example, a fingerprint of a first compiled computer binary can be generated for purposes of identifying theft of the underlying code. Other compiled computer binaries can then be collected over a period of time, and then fingerprints can be generated using the other compiled computer binaries for comparison with the first compiled computer binaries.
- These other compiled computer binaries can be obtained in any manner, such as, for example, using a web spider that crawls across the Internet and collects compiled computer binaries.
- the other compiled computer binaries can also be manually input.
- the owner of a first compiled computer binary may suspect that a second compiled computer binary contains code stolen from the first compiled computer binary.
- the fingerprints can be generated from the first and second compiled computer binaries at approximately the same time and then compared using the inventive fingerprint matching technique.
- FIG. 2 is a block diagram of an exemplary system for generating and matching fingerprints in accordance with the present invention.
- the system 200 can comprise one or more computers that include a processor 205 coupled to memory 210, input 215, and output 220.
- the disclosed processes can be performed by processor 205 executing computer code stored in memory 210.
- the processor 205 can be any type of processor, including a microprocessor, field programmable gate array (FPGA), and/or an application specific integrated circuit (ASIC).
- Memory 210 can be any type of non-transitory memory.
- memory 210 can also store the generated fingerprints. Alternatively or additionally, a separate storage medium can store the generated fingerprints.
- the computer binaries, fingerprints, and comparison scores can be stored in a distributed file system and nonrelational, distributed database.
- Input 215 provides mechanisms for controlling the disclosed processes, including, for example, a keyboard, mouse, trackball, trackpad, touchscreen, etc. Further, input 215 can include a connection to an external storage device for providing compiled computer binaries, such as an external hard drive or flash storage memory, as well as a network connection.
- Output 220 can include a display, printer, and/or the like. Additionally, output 220 can include a network connection for notifying an owner of a compiled computer binary of any identified potential infringement, such as by electronic mail, posting on a website or webpage, a text message, and/or the like.
- FIG. 3 is a flow diagram of an exemplary process for generating a fingerprint using binary code in accordance with the present invention. This process is performed using the system of Figure 2.
- processor 205 receives a compiled computer binary (step 305) via input 215 and/or memory 210 and measures bulk file characteristics and meta-data (step 310).
- processor 205 disassembles the compiled computer binary, generates a control flow graph from the disassembled binary, and generates function call graphs for each function in the control flow graph (step 315).
- the remainder of the processing can be performed independent of the particular language, operating system, or architecture that the code was written for.
- FIG. 4 is a block diagram of an exemplary call graph in accordance with the present invention.
- a call graph describes the relationship between various functions in a compiled binary.
- a main function 405 also commonly referred to as a routine
- sub-functions 410 and 415 also commonly referred to as sub-routines
- function 415 has calls to functions 420, 425, and 430
- function 425 has calls to functions 435 and 440.
- each function is commonly referred to as a node and the connections between functions are commonly referred to as edges.
- the call graph of Figure 4 is a highly simplified graph and that compiled computer binaries typically will be disassembled into much more extensive call graphs.
- FIG. 5 is a block diagram of an exemplary control flow graph in accordance with the present invention.
- a control flow graph for a function describes all possible paths that may be traversed during execution of the particular function. Examples of paths that may be executed in the function of Figure 5 include blocks 505, 515, 520, 525, 530, 535, and 545; 505, 515, 520, 525, 530, 535, 540, 550, 560, and 565; 505, 510, 515, 550, 560, and 565; and 505, 510, 515, 550, 555, and 565.
- any path with connections illustrated in Figure 5 can be traversed during the execution of the function. Further, it should be recognized that this is merely an exemplary function and that other functions are within the scope of the invention.
- processor 205 selects one of the functions for processing (step 320). As illustrated, this processing is performed along two parallel paths. It should be recognized, however, that these two paths can be performed serially, if desired. It should also be recognized that this parallel processing does not require all of the control flow graphs to be generated, and accordingly this parallel processing can be performed as control flow graphs are generated.
- first processor 205 calculates the function out-degree using the call graph for the particular function (step 325). The function out-degree represents the number of paths or calls from a particular function to other functions in the call graph.
- Next processor 205 calculates the total number of blocks within the selected function's control flow graph (step 330), and finally processor 205 calculates the total number of edges within the selected function's control flow graph (step 335).
- the edges in the control flow graph are the connections between the different blocks within this graph.
- first processor 205 calculates the leading Eigenvector of the adjacency matrix (step 340).
- the adjacency matrix is comprised of the function coordinates 620 (described below in connection with Figure 6).
- processor 205 calculates the Markov chain (step 345).
- the Markov chain is calculated starting with the leading Eigenvector and then appending connected nodes corresponding with successively smaller elements of the leading Eigenvector.
- the Markov chain provides a good low-rank approximation, or serialization, of the control flow graph that is relatively unique and particularly well-suited for further statistical analysis of the control flow graph.
- the in- degree spectrum would be [0, 2, 3, 1, 2] because block 505 does not have any incoming edges, block 515 has two incoming edges, block 550 has three incoming edges, block 560 has one incoming edge, and block 565 has two incoming edges.
- the out-degree spectrum would be [2, 2, 2, 1, 1] because blocks 505, 515, and 550 each have two outgoing edges and blocks 560 and 565 each have two outgoing edges.
- the values for each spectra and ordering of values provides a unique signature for a particular control flow graph that can be used to identify other functions that have the same or similar unique signatures.
- processor 205 determines whether there are any further functions to process (step 355). If there are ("Yes" path out of decision step 355), then the next function is selected (step 360) and the parallel processing is repeated. If not ("No" path out of decision step 355), then processor 205 generates the fingerprint of the binary using the calculated information (step 365).
- FIG. 6 is a block diagram of an exemplary fingerprint in accordance with the present invention.
- the fingerprint includes bulk file characteristics and meta-data 610, function coordinates 620, and unique spectra 630.
- the function coordinates 620 includes, for each function, the calculated out-degree, number of blocks, and number of edges.
- the unique spectra includes, for each function, the calculated block size, in-degree, and out-degree.
- FIGS 7A and 7B are flow diagrams of an exemplary process for matching fingerprints in accordance with the present invention. This process is performed using the system of Figure 2.
- processor 205 receives two fingerprints of compiled computer binaries via input 215 and/or memory 210 (step 705) and compares their bulk file characteristic and meta-data (step 710).
- the bulk file characteristic can include measuring the Jaccard Similarity, which is a numerical score representing the amount of overlap between strings contained in both fingerprints, and is typically between 0 and 1.
- processor 205 computes distances between each pair of possible functions of the two fingerprints using the function coordinates 620 of the respective fingerprints (step 720).
- Processor 205 sorts the distances sorted (step 720) and discards function pairs having distances greater than a threshold distance (step 725). This step reduces the processing load because only the most-likely related functions will have distances below the threshold.
- the particular threshold value can be selected depending upon the available processing power of the computer and the desired run-time of the fingerprint comparison process.
- those skilled in the art will recognize that above a certain distance it is highly unlikely that functions will be related, and thus at least some thresholding should be performed to reduce unnecessary processing.
- Processor 205 then generates a list using the remaining function pairs (step 730), and one of the function pairs from the reduced list is selected for further processing of the unique spectra 630 (step 735). Specifically, processor 205 calculates a cross-correlation for the block-size spectra (step 740), the in-degree spectra (step 745), and the out-degree spectra (step 750). It will be recognized that the cross-correlation is a measure of how closely the spectra of the two fingerprints are related. Next processor 205 determines whether any function pairs remain to be processed (step 755).
- the next function pair is selected from the reduced list (step 735) and the cross- correlation of the unique spectra are calculated (steps 740-750).
- the cross-correlation can produce a correlation coefficient indicating the degree of similarity or correlation. For example, a coefficient of -1 indicates complete anti-correlation and 1 indicates complete correlation (i.e., the two fingerprints have the same control flow graph).
- processor 205 calculates a block-size, in-degree and out-degree spectra ratios (step 760-770). These ratios are calculated by dividing a total number of respective correlation coefficients above a threshold by a total number of correlation coefficients. The threshold used for the calculation of the three ratios can be the same or different. Processor 205 then selects the maximum ratio of the unique spectra ratios (step 775) and generates a comparison score based on the selected maximum ratio (step 780). The generated comparison score is then used by processor 205 to identify infringement of one of the compiled computer binaries (step 785).
- the comparison score is generated by comparing the selected maximum ratio of the unique spectra ratios to a threshold, and accordingly infringement is identified when the selected maximum ratio is above the threshold.
- the threshold can be set, for example, by training the system using known data and a particular compiled computer binary for which it is to be determined whether there are other compiled computer binaries infringing the particular compiled computer binary. This training identifies commonalities between the known data and the particular compiled computer binary so that the threshold can be set to avoid false positives indicating infringement due to code commonly used across different pieces of software that would not be an indicator of infringement.
- processor 205 can notify the owner of one of the compiled computer binaries of the potential infringement via output 220 (step 790).
- the notification can include details of the regions of the allegedly infringing computer binary that is most likely involved in the infringement.
- the collection of compiled computer binaries, fingerprint generation, and fingerprint matching can be automated and scheduled to execute using any type of task scheduling technique.
- the present invention provides a particularly cost- and time-effective way to discover, remediate, and enforce intellectual property rights, and accordingly acts as a deterrence against the theft of software code. Further, by identifying infringement based on the functions contained within compiled computer binaries, the present invention can identify an entirely copied compiled computer binary, as well as copied portions of a compiled computer binary.
