In addition, the translator may be configured to perform a bi-directional translation between the two streams as well as translation between two distinct protocol sequences. Further a translator may working in streaming mode, to facilitate streaming processing of documents.

Systems and methods are disclosed for protecting a computer program from unauthorized analysis and modification. Obfuscation transformations can be applied to the computer program's local structure, control graph, and / or data structure to render the program more difficult to understand and / or modify. Tamper-resistance mechanisms can be incorporated into the computer program to detect attempts to tamper with the program's operation. Once an attempt to tamper with the computer program is detected, the computer program reports it to an external agent, ceases normal operation, and / or reverses any modifications made by the attempted tampering. The computer program can also be watermarked to facilitate identification of its owner. The obfuscation, tamper-resistance, and watermarking transformations can be applied to the computer program's source code, object code, or executable image.

A method and system for modifying computer program logic with respect to a predetermined aspect, comprising (a) before run time: analyzing compiled computer program logic of a module for processes involving the predetermined aspect before run time, substantially without decompilation or reference to computer program source code; and storing a set of modifications relating to computer program logic modifications of the module relating to the predetermined aspect; and (b) at run time: based on the stored set of modifications, selectively transferring program control from the module to a separate logical structure, executing modified logical operations with respect to the predetermined aspect, and subsequently returning program control to the module. The predetermined aspect may be, for example, a data type, algorithm type, or interface specification. In a preferred embodiment, the predetermined aspect is date related data, and more particularly, to logical operations relating to date related data which are flawed. The system preferably operates in a mainframe environment, wherein the compiled computer program constitutes one or more load modules, executing under an operating system, wherein the computer program logic modifications preferably comprise program flow control diversions in an original object module, which selectively transfer logical control to a separate object module to effect modifications to the computer program logic, followed by a return of control to the original object module.

Apps are secured or security-wrapped either before they are downloaded onto a device, such as a smartphone or tablet device, or after they are downloaded but before they are allowed to access the device operating system and cause any potential damage to the device. An app provider, such as an employer or a cellphone provider, can secure its apps before consumers download an app from their app store or marketplace. The app is secured before it is allowed to access the operating system of the device, thereby preventing the app from malicious behavior. Core object code of the app is obtained and the digital signature is removed. App object code is substituted with security program object code, thereby creating a security-wrapped app. The security-wrapped app is prepared for execution on the device and is re-signed with a new key.

A set of user defined platform dependent compiler architecture descriptors that describe corresponding architectural features and a set of instruction predicates defining those instructions to be selected are converted to platform dependent compiler object code and instruction selector object code, respectively. The platform specific compiler having the embedded instruction selector is formed from the platform dependent compiler object code, the instruction selector object code, and the platform independent compiler object code.

An object code expansion profiler equips a program for execution profiling by preprocessing the object code files of the program so as to add profiling monitoring code to the beginning of all or substantially all functions. The preprocessing includes, for each function, the steps of grouping the function's instructions into basic blocks, counting the number of cycles required to execute the instructions of the basic block, and inserting special monitoring code with the basic block. The special monitoring code is executed each time the basic block is executed, and updates the profiling information to reflect the number of cycles required to execute the basic block. Special handling is provided for profiling calls to the Operating System (OS). The resultant profiling information is converted into a call graph image most useful for human users. For each arc in the graph connecting a calling-function / parent-node to a called-function / child node, the displayed arc image has a width logarithmically proportional to the self+descendants time for the called function.

Apps are secured or security-wrapped either before they are downloaded onto a device, such as a smart phone or tablet device, or after they are downloaded but before they are allowed to access the device operating system and cause any potential damage to the device. The app is secured before it is allowed to access the operating system of the device, thereby preventing the app from malicious behavior. App object code is substituted with security program object code, thereby creating a security-wrapped app. The app is provisioned with a geo-fencing policy which prevents execution of an app outside a pre-defined geographical area. If the device is within the defined area, the app is allowed to execute. The geographical area, such as a building or company campus, is defined using longitude and latitude coordinates and a location accuracy value. Device location is obtained using location / GPS services on the device.
