Recovering structure from binaries is disclosed. A binary file having components including a plurality of linker objects is received. A cross reference map of linker objects is created. The linker objects are associated based on calls. An address space distance for each call is determined. Boundaries are defined in the cross reference map based on the address space distance. Subsets are defined as portions of the file that are separated by the boundaries.

Recovering source code structure from program binaries

Similarity analysis of software is disclosed. An input file is received. Pairs of files that consist of the input file and files included in a corpus are categorized into one of a possible match and a mismatch. Those pairs classified as possible matches are analyzed using a pairwise component analysis.

Software similarity searching

Technologies are disclosed to transfer responsibility and control over security from player makers to content authors by enabling integration of security logic and content. An exemplary optical disc carries an encrypted digital video title combined with data processing operations that implement the title's security policies and decryption processes. Player devices include a processing environment (e.g., a real-time virtual machine), which plays content by interpreting its processing operations. Players also provide procedure calls to enable content code to load data from media, perform network communications, determine playback environment configurations, access secure nonvolatile storage, submit data to CODECs for output, and/or perform cryptographic operations. Content can insert forensic watermarks in decoded output for tracing pirate copies. If pirates compromise a player or title, future content can be mastered with security features that, for example, block the attack, revoke pirated media, or use native code to correct player vulnerabilities.
