Abstract: A method and apparatus for enabling compression of a stream of pictures according to a target bit rate are described. A first configuration parameter for a first portion is determined based at least in part on a first relative weight of the first portion with respect to a first set of N portions, where the first set of N portions includes the first portion and N-1 portions which succeed the first portion. A second configuration parameter for a second portion of a second picture is determined based at least in part on a second relative weight of the second portion with respect to a second set of M portions of pictures, where the second set of M portions includes a subset of the N-1 portions from the first set and zero or more additional portions of pictures from the stream of pictures.

Abstract: The present disclosure relates to methods for securing an application. A first method generates a unique cipher for securing the application, by performing iterations of: inputting a random number corresponding to a pre-defined operation, inputting at least one operand, and executing instructions for applying the pre-defined operation to the at least one operand. A second method secures an application by means of a multi-threaded cipher, which executes a ciphering function as a plurality of threads. Two threads of the ciphering function are performed in synchronicity. A third method secures an application by means of a multi-level cipher. The application is secured by applying an application cipher part and an OS cipher part. A fourth method secures an application by means of a multi-level security function. The application is secured by executing an application part security function and an OS part security function.

Abstract: A system and method for transforming a software application comprising binary code and optionally associated data, from an original form to a more secure form. The method includes performing a combination of binary transmutations to the application, and interlocking the transmutations by generating and placing interdependencies between the transmutations, wherein a transmutation is an irreversible change to the application. Different types of the transmutations are applied at varied granularities of the application. The transmutations are applied to the application code and the implanted code as well. The result is a transformed software application which is semantically equivalent to the original software application but is resistant to static and/or dynamic attacks.
