A method and apparatus to modify control devices residing on a Fieldbus communications network, without interrupting the operation of the control devices. The control device updating may further be controlled and monitored by a remotely located host that also communicates on the Fieldbus network. The control device may comprise at least two distinct memory areas, wherein at least one memory area must be active, and at least one memory area must be inactive. Active memory areas provide the control device microprocessor operating system with executable instructions or data. The host downloads new executable instructions or data to inactive memory areas, with associated data entry points, during unscheduled communications periods wherein data input / output is not being performed between the control device and the host or another control device. Upon a full data transfer and proper verification of the new data, the host may issue an activation command that causes a selector device to activate the previously inactive memory area by directing the microprocessor to the entry points of the newly downloaded executable instructions or data. The memory activation must occur while the microprocessor is not performing application execution, application input / output, or application communications. By timing the memory activation in this manner, the microprocessor may be redirected to the newly downloaded executable instructions or data without microprocessor interruption.

A piracy protection system incorporates tamper detection capabilities into a protected copy of an application by disassembling a statically linked binary of the application, modifying some of the instructions in the application, and then rewriting all of the modified and unmodified instructions to a new executable file, a protected copy. The piracy protection system comprises an offline tamper detection technique in which the software itself detects the tampering and causes the program to fail, therefore protecting itself from malicious attacks. The system further comprises a dynamic software-watermarking process that incorporates code obfuscation to prevent reverse engineering.

A method and system for checking whether customer orders for transactions of financial instruments conform to business logic rules. Executable rule files are created and stored in a repository. New executable rule files can be created by scripting the new business logic rules in a script file which is converted into a corresponding source code file written in a computer programming language. The source code file is compiled to create an individual executable rule file. A rule selection repository contains identification of groups of selected executable rule files. The invention determines the category of the customer order and reads, from the rule selection repository, a group of executable rule files that correspond to the identified category of the customer order. The selected executable rule files are executed to check the conformance of the customer order. Execution results are stored in a status repository for subsequent retrieval and analysis.

The invention discloses a method and device for implementing hot update of executable files of a smart card. The method includes: when the card receives a start hot update command sent by a host computer, acquiring the executable file to be updated; The file registry information of the executable file to be updated, the registry information of all applications belonging to the executable file to be updated in the registry, and the user information specified by all applications to be backed up are backed up to the first storage area of ​​the non-volatile memory ;Download the new executable file and reinstall the application according to the backup file registry information and the backup application registry information through the new executable file, and call the backup function in the reinstalled application to save the User information is restored to the reinstalled app. The invention can update executable files and applications to be updated, and retain the previous data of application users, which is convenient for users to use and improves user experience.
