摘要： Systems and methods are discussed that allow profile information to be reused by various versions of a program. One illustrative aspect includes a method for comparing versions of a program in binary format. The method includes finding equivalent contents in portions of two versions of the program, finding equivalent structure in the portions of the two versions, and forming a match when a portion of one of the two versions is an equivalence of a portion of the other of the two versions.

摘要： Systems, methods, and/or techniques (“tools”) are described herein that relate to automated secure pairing for devices, and that relate to parallel downloads of content using devices. The tools for pairing the devices may perform authentication protocols that are based on addresses and on keys. The address-based authentication protocol may operate on address book entries maintained by the devices. The key-based authentication protocol may operate using a key exchange between the devices.

摘要： Techniques are disclosed to provide randomized signal transforms and/or their applications. More particularly, a signal (e.g., an audio signal, an image, or a video signal) is transformed by applying randomly-selected basis functions to the signal. The applications of the randomized signal transforms include, but are not limited to, compression, denoising, hashing, identification, authentication, and data embedding (e.g., watermarking).

摘要： A classification system is described for resilient classification of data. In various embodiments, the classification system divides a full set of the training data into a positive subset and a negative subset. The positive subset contains all training data with a positive classification value and the negative subset contains all training data with a negative classification value. The classification system constructs several subsets of the training data wherein each subset contains data randomly selected from both the positive subset and the negative subset. The classification system then creates at least two classifiers based on each of the randomly created subsets of the training data.

摘要： The present invention leverages a series of media watermark locations to provide information relating to media ownership and/or distribution source. This provides a forensic means to establish a source of media with a high degree of certainty despite malicious and/or non-malicious attacks. By providing embedded user unique identification, a source of copied media can be determined without the embedded information substantially interfering with the intended purpose of the media itself. In one instance of the present invention, digital media is transformed into an N-dimensional media signal. User unique keys are then utilized along with a master key to determine locations for embedding a watermark signal that possesses substantially similar quantized statistics as the transformed media signal. The watermark signal is then embedded into the media signal, fingerprinting the media.

摘要： Software protection using data structures is described. In one implementation, an engine between the processor and the memory of a computing device encrypts and stores data and program variables in blocks of memory that correspond to nodes of a tree-like data structure. When accessed, the nodes of this search tree are rearranged according to various schemata to obscure memory access patterns from being detected by cache attacks or side-channel attacks. In one implementation, the data structure is a splay tree that self-rearranges upon access and increases efficiency while providing security.

摘要： A technique for imparting substantial break-once-run-everywhere (BORE) resistance to passive and active software objects, and for controlling access and use of resulting protected objects by a client computer (400). Specifically, a relatively large number, n, of identical watermarks (1720) are embedded throughout a software object (1700), through use of n different secret watermark keys to form a protected object, with each key defining a pointer to a location in the protected object at which a corresponding watermark appears.
